Description

[Technical field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing program for evaluating a user's stress level. [Background technology]

[0002] In recent years, it has become an issue that occupational stress can induce stress disorders such as mental illness (mental illness, depression, etc.), mental burden, maladaptive behavior, and cognitive problems, and a stress check system has been introduced to periodically examine the stress status of workers. In this stress check system, workers with high stress levels are selected based on a stress check questionnaire, and a doctor provides interview guidance to these workers.

[0003] Such stress check systems have become mandatory for certain business operators, and in recent years various systems have been proposed for introducing stress check systems using IT technology.

[0004] For example, Patent Document 1 discloses a stress check system that notifies the examinee's terminal of information related to a questionnaire for a stress check and requests the examinee to answer, and also notifies the examinee's terminal of an answer reminder if the examinee has not answered yet. This stress check system can provide a technology that helps the business operator to appropriately and promptly conduct an occupational stress check and the accompanying interview guidance by grasping the general state of the examinee's answers and notifying the answer reminder. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2017-97772 A Summary of the Invention [Problem to be solved by the invention]

[0006] Under the current stress check system, which was implemented in December 2015 under the revised Industrial Safety and Health Act, workplaces with 50 or more employees are required to conduct stress checks once a year. This makes it possible to select high-stress workers based on a stress check questionnaire and have a doctor interview them for guidance. However, in order to properly grasp the causes of stress, the questionnaire tends to have many questions, which creates a problem in that the burden on users to answer the questions is relatively large. If the burden on users becomes too large, there is a risk that some workers will hesitate to take the stress check, or take the stress check for the sake of appearance without giving sufficient thought to the questions on the questionnaire.

[0007] Here, according to the technology described in Patent Document 1, it seems that the stress check system using IT technology can efficiently carry out the occupational stress check. However, this technology ensures the speed of the occupational stress check by having the business operator grasp the overview of the examinee's answers and notify the examinee of the answer reminder, and does not reduce the burden on the user who takes the occupational stress check. Furthermore, there is still room for improvement in the technology to carry out the occupational stress check more simply and efficiently.

[0008] An object of the present disclosure is to provide technology that enables occupational stress checks to be carried out more simply and efficiently. [Means for solving the problem]

[0009] The information processing device disclosed herein is an information processing device that evaluates the level of stress of a user. The information processing device includes a control unit that executes acquiring response information from the user to a simple questionnaire that includes three areas related to causes, reactions, and influencing factors of stress, and evaluating the level of stress of the user based on the response information. The control unit acquires the response information to the simple questionnaire that is generated based on a predetermined analysis of each of the three areas in a predetermined standard questionnaire.

[0010] The information processing device described above can significantly reduce the burden on workers (users) when answering the occupational stress check. This improves the response rate of workers (users) to the occupational stress check, and further reduces the burden by efficiently checking using a simple questionnaire, making it easier to repeat the check multiple times, such as monthly, and enabling it to be used in conjunction with surveys other than stress checks.

[0011] Here, in the above information processing device, the cause area of ​​the three areas in the simple questionnaire may include a first group of questions that are questions selected from four causal factors. In this case, the first group of questions may include questions about the quantitative burden of work and work control. Alternatively, the reaction area of ​​the three areas in the simple questionnaire may include a second group of questions that are questions selected from two reaction factors. In this case, the second group of questions may include questions about anxiety and mental and physical fatigue. Alternatively, the influencing factor area of ​​the three areas in the simple questionnaire may include a third group of questions that are questions selected from two influencing factors. In this case, the third group of questions may include questions about support from the workplace and support from family and friends.

[0012] In addition, in the information processing device of the present disclosure, the simplified questionnaire may be a questionnaire composed of questions selected from factors having factor loadings equal to or greater than a predetermined value in an exploratory factor analysis for each of the three areas, and questions about work burden, which is one of the factors included in the cause area of ​​the three areas, that may have a negative impact on the user.

[0013] In the information processing device described above, the control unit may evaluate the user's level of stress as a high stress state when the reaction evaluation result, which is the evaluation result in the reaction area of ​​the three areas, is equal to or greater than a predetermined first evaluation criterion, regardless of the evaluation results in the cause area and the influencing factor area of ​​the three areas, and when the reaction evaluation result is less than the first evaluation criterion and equal to or greater than a predetermined second evaluation criterion, and when the sum of the evaluation results in the cause area and the influencing factor area of ​​the three areas is equal to or greater than a predetermined third evaluation criterion, evaluate the user's level of stress as the high stress state.

[0014] The present disclosure can also be understood from the aspect of an information processing method by a computer. That is, the information processing method of the present disclosure is an information processing method for evaluating a user's stress level, in which a computer executes the following: acquiring answer information from the user to a simplified questionnaire including three areas related to causes, reactions, and influencing factors of stress, the simplified questionnaire being generated based on factor analysis for each of the three areas in a predetermined reference questionnaire; and evaluating the user's stress level based on the answer information. In this case, the computer may execute the following: when a reaction evaluation result, which is an evaluation result in the reaction area of ​​the three areas, is equal to or greater than a predetermined first evaluation standard, the computer may evaluate the user's stress level as a high stress state regardless of the evaluation results in the cause area and the influencing factor area of ​​the three areas; and when the reaction evaluation result is less than the first evaluation standard and equal to or greater than a predetermined second evaluation standard, the computer may execute the following if a sum of the evaluation results in the cause area and the influencing factor area of ​​the three areas is equal to or greater than a predetermined third evaluation standard, the computer may execute the following if a sum of the evaluation results in the cause area and the influencing factor area of ​​the three areas is equal to or greater than a predetermined third evaluation standard.

[0015] The present disclosure can also be understood from the aspect of an information processing program. That is, the information processing program of the present disclosure is an information processing program for evaluating the degree of stress of a user, and causes a computer to execute the following: acquiring answer information from the user to a simplified questionnaire including three areas related to causes, reactions, and influencing factors of stress, the simplified questionnaire being generated based on factor analysis for each of the three areas in a predetermined reference questionnaire; and evaluating the degree of stress of the user based on the answer information. In this case, the computer may be caused to evaluate the degree of stress of the user as a high stress state when a reaction evaluation result, which is an evaluation result in the reaction area of ​​the three areas, is equal to or greater than a predetermined first evaluation standard, regardless of the evaluation results in the cause area and the influencing factor area of ​​the three areas; and, when the reaction evaluation result is less than the first evaluation standard and equal to or greater than a predetermined second evaluation standard, evaluating the degree of stress of the user as the high stress state when the sum of the evaluation results in the cause area and the influencing factor area of ​​the three areas is equal to or greater than a predetermined third evaluation standard.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The configurations of the following embodiments are merely examples, and the present disclosure is not limited to the configurations of the embodiments.

[0019] First Embodiment The outline of the information processing system in the first embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing a schematic configuration of the information processing system in the present embodiment. The information processing system 100 according to the present embodiment includes a network 200, a server 300, and a user terminal 400. The information processing system of the present disclosure is a system for evaluating the degree of stress of a user, and the evaluation of the degree of stress is performed by the server 300. In the following description, among the user users who use the information processing system 100, workers who take the occupational stress check are referred to as examinee users, and among the user users who use the information processing system 100, businesses that have workers take the occupational stress check are referred to as implementer users. Each of the examinee users and implementer users may have a user terminal 400.

[0020] The network 200 is, for example, an IP network. If the network 200 is an IP network, it may be wireless, wired, or a combination of wireless and wired. For example, in the case of wireless communication, the user terminal 400 may access a wireless LAN access point (not shown) and communicate with the server 300 via a LAN or WAN. Furthermore, the network 200 is not limited to these examples, and may be, for example, a public switched telephone network, an optical fiber line, an ADSL line, a satellite communication network, or the like.

[0021] The server 300 is connected to a user terminal 400 via a network 200. For ease of explanation, one server 300 and four user terminals 400 are shown in Fig. 1, but it goes without saying that the number of users is not limited to this.

[0022] The server 300 may be any electronic device having a processing capability for arithmetic processing such as data acquisition, generation, and updating, and processing, such as a personal computer, a server, a mainframe, or other electronic device. That is, the server 300 may be configured as a computer having a processor such as a CPU or GPU, a main storage device such as a RAM or ROM, and an auxiliary storage device such as an EPROM, a hard disk drive, or a removable medium. The removable medium may be, for example, a USB memory or a disk recording medium such as a CD or DVD. The auxiliary storage device stores an operating system (OS), various programs, various tables, and the like.

[0023] In addition, the server 300 may appropriately use SaaS (Software as a Service), Paas (Platform as a Service), or IaaS (Infrastructure as a Service) provided by a cloud server, without providing software, hardware, an OS, etc., dedicated to the information processing system 100 of this embodiment.

[0024] The user terminal 400 may be any electronic device such as a mobile terminal owned by a user (this includes test taker users and implementer users) who uses the information processing system 100, and may be, for example, a mobile terminal, a tablet terminal, a smartphone, a wearable terminal, a personal computer, or other terminal devices.

[0025] Next, the components of the server 300 will be mainly described in detail with reference to Fig. 2. Fig. 2 shows the components of the server 300 included in the information processing system 100 in the first embodiment in more detail, and also shows the components of the user terminal 400 that communicates with the server 300.

[0026] The server 300 has, as functional units, a communication unit 301, a storage unit 302, and a control unit 303, and can realize functions that match the predetermined purpose of each functional unit by loading a program stored in an auxiliary storage device into a working area of ​​a main storage device and executing the program, and controlling each functional unit through the execution of the program. However, some or all of the functions may be realized by hardware circuits such as ASIC and FPGA.

[0027] Here, the communication unit 301 is a communication interface for connecting the server 300 to the network 200. The communication unit 301 includes, for example, a network interface board and a wireless communication circuit for wireless communication. The server 300 is connected to the user terminal 400 and other external devices via the communication unit 301 so as to be able to communicate with them.

[0028] The storage unit 302 includes a main storage unit and an auxiliary storage unit. The main storage unit is a memory in which the programs executed by the control unit 303 and data used by the control programs are expanded. The auxiliary storage unit is a device in which the programs executed by the control unit 303 and data used by the control programs are stored. A simple questionnaire, which will be described later, is stored in advance in the storage unit 302. The storage unit 302 also stores data transmitted from the user terminal 400 and the like, and the storage unit 302 can store answer information, which will be described later. The server 300 can acquire data transmitted from the user terminal 400 and the like via the communication unit 301.

[0029] The control unit 303 is a functional unit that manages the control performed by the server 300. The control unit 303 can be realized by an arithmetic processing device such as a CPU. The control unit 303 further includes two functional units, an acquisition unit 3031 and an evaluation unit 3032. Each functional unit may be realized by executing a stored program by the CPU.

[0030] The acquiring unit 3031 acquires answer information from the test-taker user to the simplified questionnaire. Here, the simplified questionnaire is a questionnaire including three areas related to causes, reactions, and influencing factors of stress, and is generated based on a predetermined analysis of each of the three areas in a predetermined standard questionnaire. As described below, the answer information may be transmitted from the user terminal 400 of the test-taker user. The acquiring unit 3031 acquires the answer information by acquiring information transmitted from the user terminal 400 of the test-taker user, and stores the answer information in the memory unit 302 of the server 300.

[0031] Here, the user terminal 400 in this embodiment has a communication unit 401, an input / output unit 402, and a storage unit 403 as functional units. The communication unit 401 is a communication interface for connecting the user terminal 400 to the network 200, and is configured to include, for example, a network interface board and a wireless communication circuit for wireless communication. The input / output unit 402 is a functional unit for displaying information transmitted from the outside via the communication unit 401, and inputting the information when transmitting the information to the outside via the communication unit 401. The storage unit 403 is configured to include a main storage device and an auxiliary storage device, similar to the storage unit 302 of the server 300.

[0032] The input / output unit 402 further includes a display unit 4021, an operation input unit 4022, and an image / audio input / output unit 4023. The display unit 4021 has a function of displaying various information, and is realized, for example, by an LCD (Liquid Crystal Display) display, an LED (Light Emitting Diode) display, an OLED (Organic Light Emitting Diode) display, or the like. The operation input unit 4022 has a function of accepting operation input from a user, and is specifically realized by soft keys or hard keys such as a touch panel. The image / audio input / output unit 4023 has a function of accepting input of images such as still images and videos, and is specifically realized by a camera using an image sensor such as a Charged-Coupled Devices (CCD), a Metal-oxide-semiconductor (MOS), or a Complementary Metal-Oxide-Semiconductor (CMOS). The image / audio input / output unit 4023 has a function of accepting input and output of audio, and is specifically realized by a microphone or a speaker.

[0033] The test-taker user can then use the user terminal 400 configured in this manner to transmit answer information to the server 300. Here, the server 300 may provide the user terminal 400 of the test-taker user with an interface for inputting answer information. The test-taker user can then transmit answer information to the server 300 by inputting information into the interface via the user terminal 400.

[0034] The evaluation unit 3032 evaluates the stress level of the test-taker user based on the above-mentioned answer information. Details of the process executed by the evaluation unit 3032 will be described later with reference to FIG.

[0035] The control unit 303 executes the processes of the acquisition unit 3031 and the evaluation unit 3032, thereby functioning as a control unit according to the present disclosure.

[0036] Here, the flow of operations of the information processing system 100 in this embodiment will be described. Fig. 3 is a diagram illustrating the flow of operations of the information processing system 100 in this embodiment. Fig. 3 illustrates the flow of operations between the server 300 and the user terminal 400 in the information processing system 100 in this embodiment, and the processing executed by the server 300 and the user terminal 400. The flow illustrated in Fig. 3 illustrates the flow of operations between the server 300 and the user terminals 400 of the test taker users and the implementer users, and the processing executed by the server 300 and the user terminals 400 of the test taker users and the implementer users.

[0037] In this embodiment, first, the test-taker user information is input to the user terminal 400 of the implementer user (S101). Here, the test-taker user information is information including the name, identification information, contact information, etc. of the test-taker user, and the implementer user can input such test-taker user information using a specified interface. The test-taker user information is then transmitted from the user terminal 400 of the implementer user to the server 300. The server 300 then acquires the information transmitted from the user terminal 400 of the implementer user (S102).

[0038] Next, the server 300 executes a process of calling up the simplified questionnaire (S103). As described above, the simplified questionnaire is a questionnaire that includes three areas related to causes, reactions, and influencing factors of stress, and is generated based on a predetermined analysis of each of the three areas in a predetermined standard questionnaire.

[0039] Here, in the past, occupational stress checks often used a questionnaire with 57 questions provided by the Ministry of Health, Labor and Welfare. This questionnaire corresponds to the standard questionnaire mentioned above.

[0040] This standard questionnaire (a questionnaire with 57 questions) includes questions related to the causes area shown in Table 1 below. [Table 1]

[0041] In addition, the baseline questionnaire (a questionnaire with 57 questions) includes questions that fall into the response domains shown in Table 2 below. [Table 2]

[0042] In addition, the standard questionnaire (a questionnaire with 57 questions) includes questions that belong to the area of ​​influencing factors shown in Table 3 below. [Table 3]

[0043] In addition, the baseline questionnaire (a questionnaire with 57 questions) also included the questions shown in Table 4 below. [Table 4]

[0044] By conducting an occupational stress check using such a standard questionnaire, it becomes possible to select high-stress individuals from among workers and have them undergo interview guidance by a doctor.

[0045] However, the standard questionnaire has a relatively large number of questions (57) to properly grasp the stress factors of workers, and this causes a problem that the burden on the test-taker user to answer the questions is relatively large. If the burden on the test-taker user is large in this way, there is a risk that some workers will hesitate to take the stress check, or take the stress check for the sake of formality without giving sufficient thought to the questions on the questionnaire.

[0046] Therefore, as a result of careful consideration, the present inventor has newly discovered that it is possible to easily and appropriately evaluate the level of stress of a test-taker user based on a simplified questionnaire generated by the following analysis for each of the three areas of cause, reaction, and influencing factors in the above-mentioned standard questionnaire, and a specific evaluation method for the simplified questionnaire.

[0047] Here, the first group of questions, which are questions included in the cause area of ​​the simple questionnaire, are shown in Table 5 below. [Table 5]

[0048] The first group of questions shown in Table 5 above are questions about the quantitative burden of work and work control, and can be selected from the four causal factors included in the cause area of ​​the standard questionnaire above (quantitative and qualitative burden of work, lack of job satisfaction / mismatch in suitability, interpersonal problems, and lack of a sense of control).

[0049] Additionally, the second group of questions, which are questions included in the response area of ​​the simple questionnaire, are shown in Table 6 below. [Table 6]

[0050] The second set of questions shown in Table 6 above are questions about anxiety and mental and physical fatigue, and can be selected from two response factors (depression / anxiety, and mental and physical fatigue) included in the response area of ​​the standard questionnaire mentioned above.

[0051] Additionally, the third group of questions, which are questions included in the area of ​​influencing factors in the simple questionnaire, are shown in Table 7 below. [Table 7]

[0052] The third group of questions shown in Table 7 above are questions about support from the workplace and from family and friends, and can be selected from the two influencing factors included in the influencing factors area of ​​the baseline questionnaire above (support from superiors and colleagues, support from family and friends).

[0053] 3, the server 300 transmits the above-mentioned simplified questionnaire to the user terminal 400 of the test-taker user (S104). The user terminal 400 of the test-taker user then acquires the information transmitted from the server 300 (S105).

[0054] Then, answer information to the simple questionnaire is input to the user terminal 400 of the test-taker user (S106). Here, the answer information is information including the answers of the test-taker user to the questions included in the simple questionnaire. The test-taker user can input such answer information using a specified interface. Then, the answer information is transmitted from the user terminal 400 of the test-taker user to the server 300.

[0055] When the server 300 receives the answer information transmitted from the user terminal 400 of the test-taker user (S107), it then executes an evaluation process for evaluating the stress level of the test-taker user based on the answer information (S108). This evaluation process will be described below with reference to Figs. 4 and 5.

[0056] Fig. 4 is a diagram illustrating an example of evaluation raw scores for answers to a simple questionnaire in this embodiment, and Fig. 5 is a first diagram for explaining a method for evaluating the stress level of a test-taker user based on answers to a simple questionnaire in this embodiment.

[0057] In the flowchart of the evaluation method illustrated in FIG. 5, first, the evaluation raw scores are summed up for each area of ​​stress causes, reactions, and influencing factors (S1081). Here, in this embodiment, as illustrated in FIG. 4, an evaluation raw score of 1 to 4 points is given to the answer to each question item of the simple questionnaire. For example, the answer options to the question item "I can't finish my work within the time" in the area of ​​stress causes are "Yes", "Somewhat yes", "Slightly different", and "Different". If the test-taker user answers "Yes", an evaluation raw score of 4 points is given, if the test-taker user answers "Somewhat different", an evaluation raw score of 3 points is given, if the test-taker user answers "Somewhat different", an evaluation raw score of 2 points is given, and if the test-taker user answers "I can work at my own pace", an evaluation raw score of 1 point is given, if the test-taker user answers "Yes", an evaluation raw score of 2 points is given, if the test-taker user answers "Somewhat different", an evaluation raw score of 3 points is given, and if the test-taker user answers "I can work at my own pace", an evaluation raw score of 4 points is given.

[0058] For example, the answer options for the question "Very tired" in the stress reaction area are "Almost never", "Sometimes", "Often", and "Almost always", and if the test-taker user answers "Almost never", an evaluation score of 1 point is given, if the test-taker user answers "Sometimes", an evaluation score of 2 points is given, if the test-taker user answers "Often", an evaluation score of 3 points is given, and if the test-taker user answers "Almost always", an evaluation score of 4 points is given. For example, the answer options for the question "How easily can you talk with your boss?" in the stress influence factor area are "Very", "Quite", "Somewhat", and "Not at all", and if the test-taker user answers "Very", an evaluation score of 1 point is given, if the test-taker user answers "Quite", an evaluation score of 2 points is given, if the test-taker user answers "Somewhat", an evaluation score of 3 points is given, and if the test-taker user answers "Not at all", an evaluation score of 4 points is given.

[0059] Then, in the process of S1081, the server 300 calculates the total score of the above-mentioned evaluation raw scores for each question item included in each area of ​​causes, reactions, and influencing factors of stress.

[0060] 5, next, in S1082, the server 300 determines whether the total score of the stress reaction area (corresponding to the reaction evaluation result of the present disclosure) is 17 points or more (corresponding to the first evaluation standard of the present disclosure). If the determination in S1082 is affirmative, the server 300 proceeds to processing of S1085, and if the determination in S1082 is negative, the server 300 proceeds to processing of S1083.

[0061] If the determination in S1082 is negative, then in S1083, the server 300 determines whether the total score combining the stress cause area and the influencing factor area is 16 points or more (corresponding to the third evaluation criterion of the present disclosure). If the determination in S1083 is positive, the server 300 proceeds to processing of S1084, and if the determination in S1083 is negative, the server 300 proceeds to processing of S1086.

[0062] If the determination in S1083 is affirmative, then in S1084, the server 300 determines whether the total score of the stress reaction area is 13 points or more (corresponding to the second evaluation criterion of the present disclosure). If the determination in S1084 is affirmative, the server 300 proceeds to processing of S1085, and if the determination in S1084 is negative, the server 300 proceeds to processing of S1086.

[0063] If the result of S1082 is affirmative or if the result of S1084 is affirmative, then in S1085, the test-taker user having such answer information is evaluated for a high stress state as a stress level. After the process of S1085, the execution of this flow is terminated.

[0064] On the other hand, if the result of S1083 is negative, or if the result of S1084 is negative, then in S1086, the test-taker user having such answer information is evaluated as having no problem with his / her stress level. After the process of S1086, the execution of this flow is terminated.

[0065] In other words, in this embodiment, if the evaluation result in the reaction area of ​​the three areas of cause, reaction, and influencing factors is 17 points (first evaluation criterion) or more, the server 300 evaluates the level of stress of the test-taker user as a high stress state regardless of the evaluation results in the cause area and influencing factor area of ​​the three areas, and if the evaluation result in the reaction area is less than 17 points (first evaluation criterion) and 13 points (second evaluation criterion) or more, and the total evaluation results in the cause area and influencing factor area of ​​the three areas is 16 points (third evaluation criterion) or more, the server 300 evaluates the level of stress of the test-taker user as a high stress state.

[0066] Furthermore, the present disclosure verified the validity of the assessment of the stress level of the test-taker user based on the above-mentioned simple questionnaire and the above-mentioned evaluation method for the simple questionnaire by comparing it with an occupational stress check using a standard questionnaire.

[0067] In detail, a comparison of the occupational stress checks of 18,155 people using the standard questionnaire and the simple questionnaire and its evaluation method disclosed herein showed that the number of test-takers whose stress level was determined to be high was 16,581, and it was confirmed that the recall rate of the simple questionnaire and its evaluation method disclosed herein was 91.3% compared to the standard questionnaire. This demonstrated the validity of using the simple questionnaire and its evaluation method disclosed herein.

[0068] 3, the server 300 transmits the evaluation result by the above-mentioned evaluation process to the user terminal 400 of the implementer user (S109). Then, the user terminal 400 of the implementer user acquires the information transmitted from the server 300 (S110).

[0069] According to the above-described process, in a stress check system utilizing IT technology, by using a simple questionnaire, in other words, by simplifying the questions, the burden required for the examinee user to answer the questions can be significantly reduced. This improves the response rate from workers to the occupational stress check, and furthermore, by reducing the burden due to efficient checking using the simple questionnaire, it becomes easy to repeat the test multiple times, such as monthly, and it becomes possible to use the test in combination with other surveys. In this way, the technology disclosed herein suggests new possibilities for the use of stress checks. From the perspective of the person who implements the stress check, when selecting high-stress workers from among the workers based on the questionnaire related to the stress check and conducting interview guidance for the high-stress workers by a doctor, the effects of the simple questionnaire, such as an improvement in the response rate from workers and the ability of the workers to fully consider the questions when answering the questions, and the validity of using the simple questionnaire and the evaluation method disclosed herein described above, make it possible to implement the occupational stress check more efficiently.

[0070] The evaluation process based on the answer information of the simple questionnaire of the present disclosure may use the evaluation method described below. Figures 6a to 6c are second diagrams for explaining the evaluation method of the stress level of the test-taker user evaluated based on the answers to the simple questionnaire in this embodiment.

[0071] In the flowchart of the evaluation method illustrated in Fig. 6a, first, the raw evaluation scores for each of the areas of causes, reactions, and influencing factors of stress are totaled (S2081). The process of S2081 is similar to the process of S1081 shown in Fig. 5 above.

[0072] In the flow shown in Fig. 6a, next, in S2082, the server 300 determines whether or not the total score of the stress reaction area is equal to or greater than 19. If the determination in S2082 is affirmative, the server 300 proceeds to processing of S2085, and if the determination in S2082 is negative, the server 300 proceeds to processing of S2083.

[0073] If the determination in S2082 is negative, then in S2083, the server 300 determines whether or not the total score combining the stress cause area and the stress influencing factor area is 19 points or more. If the determination in S2083 is positive, the server 300 proceeds to the process of S2084, and if the determination in S2083 is negative, the server 300 proceeds to the flow shown in FIG. 6b.

[0074] If the determination in S2083 is affirmative, then in S2084, the server 300 determines whether or not the total score of the stress reaction area is equal to or greater than 15. If the determination in S2084 is affirmative, the server 300 proceeds to the process of S2085, and if the determination in S2084 is negative, the server 300 proceeds to the flow shown in FIG.

[0075] If the result of S2082 is affirmative or if the result of S2084 is affirmative, then in S2085, the stress level of the test-taker user having such answer information is evaluated as being in an extremely high stress state. After the process of S2085, the execution of this flow is terminated.

[0076] On the other hand, if the determination in S2083 is negative, or if the determination in S2084 is negative, then in S3082 of the flow shown in Fig. 6b, the server 300 determines whether or not the total score of the stress reaction area is 17 points or more. If the determination in S3082 is positive, the server 300 proceeds to the process of S3085, and if the determination in S3082 is negative, the server 300 proceeds to the process of S3083.

[0077] If a negative determination is made in S3082, then in S3083, the server 300 determines whether or not the total score combining the stress cause area and the influencing factor area is equal to or greater than 16. If a positive determination is made in S3083, the server 300 proceeds to the process of S3084, and if a negative determination is made in S3083, the server 300 proceeds to the flow shown in FIG.

[0078] If the determination in S3083 is affirmative, then in S3084, the server 300 determines whether or not the total score in the stress reaction area is equal to or greater than 13. If the determination in S3084 is affirmative, the server 300 proceeds to the process of S3085, and if the determination in S3084 is negative, the server 300 proceeds to the flow shown in FIG.

[0079] If the result of S3082 is affirmative or if the result of S3084 is affirmative, then in S3085, the test-taker user having such answer information is evaluated for his / her stress level and is determined to be in a high stress state. After the process of S3085, the execution of this flow is terminated.

[0080] On the other hand, if a negative determination is made in S3083 or if a negative determination is made in S3084, then in S4082 of the flow shown in Fig. 6c, the server 300 determines whether or not the total score of the stress reaction area is 15 points or more. If a positive determination is made in S4082, the server 300 proceeds to processing of S4085, and if a negative determination is made in S4082, the server 300 proceeds to processing of S4083.

[0081] If a negative determination is made in S4082, then in S4083, the server 300 determines whether or not the total score combining the stress cause area and the influencing factor area is 14 points or more. If a positive determination is made in S4083, the server 300 proceeds to processing of S4084, and if a negative determination is made in S4083, the server 300 proceeds to processing of S4086.

[0082] If an affirmative determination is made in S4083, then in S4084, the server 300 determines whether or not the total score of the stress reaction area is equal to or greater than 11. If an affirmative determination is made in S4084, the server 300 proceeds to processing of S4085, and if a negative determination is made in S4084, the server 300 proceeds to processing of S4086.

[0083] If the result of S4082 is affirmative or if the result of S4084 is affirmative, then in S4085, the test-taker user having such answer information is evaluated for a degree of stress and is judged to be in a semi-high stress state. After the process of S4085, the execution of this flow is terminated.

[0084] On the other hand, if the result of S4083 is negative, or if the result of S4084 is negative, then in S4086, the test-taker user having such answer information is evaluated as having no problem with his / her stress level. After the process of S4086, the execution of this flow is terminated.

[0085] Here, the super-high stress state is a stress state higher than the high stress state shown in Fig. 5, and it can be determined that a test-taker user judged in this way needs to be treated immediately. Also, the semi-high stress state is a stress state lower than the high stress state shown in Fig. 5, but with a higher evaluation point than the average, and it can be determined that a test-taker user judged in this way also needs to be careful.

[0086] According to the information processing system 100 described above, the occupational stress check can be carried out more simply and efficiently.

[0087] <Second embodiment> A second embodiment will be described. Fig. 7 is a diagram showing components of the server 300 included in the information processing system 100 in the second embodiment in more detail, and also showing components of the user terminal 400 that communicates with the server 300. In this embodiment, the control unit 303 is configured to have three functional units: an acquisition unit 3031, an evaluation unit 3032, and a generation unit 3033.

[0088] The generating unit 3033 is a functional unit for generating the simplified questionnaire described in the first embodiment above, and generates a simplified questionnaire that is configured with questions selected from factors with factor loadings equal to or greater than a predetermined value in an exploratory factor analysis for each of the three areas of cause, reaction, and influencing factors, and questions about work burden, which is one of the factors included in the cause area of ​​the three areas, and which may have a negative impact on workers (examinee users). This will be described in detail below.

[0089] The generating unit 3033 first performs an exploratory factor analysis on each of the three areas of causes, reactions, and influencing factors of stress in the standard questionnaire (a questionnaire with 57 questions). At this time, for example, the factor extraction method may be maximum likelihood method, the factor rotation method may be promax rotation, and questions with a factor loading of 0.4 or more and a simple structure may be adopted.

[0090] And, as a result of the above-mentioned exploratory factor analysis, it is found that the area of ​​causes of stress in the standard questionnaire (a questionnaire containing 57 questions) includes four causal factors, namely, quantitative and qualitative burden of work, lack of job satisfaction and mismatch of suitability, interpersonal problems, and lack of a sense of control, as shown in Table 8 below. [Table 8]

[0091] Similarly, the results of the above exploratory factor analysis reveal that the stress response area in the standard questionnaire (a questionnaire with 57 questions) includes two response factors: depression / anxiety and mental and physical fatigue, as shown in Table 9 below. [Table 9]

[0092] Similarly, the results of the above exploratory factor analysis reveal that the area of ​​influencing factors regarding stress in the standard questionnaire (a questionnaire with 57 questions) includes two influencing factors: support from superiors / colleagues and support from family / friends, as shown in Table 10 below. [Table 10]

[0093] Then, when the generating unit 3033 selects questions from the four factors in the cause domain, the two factors in the reaction domain, and the two factors in the influencing factor domain, it selects a question item (e.g., the question item "I can't finish my work in time") that may have a negative impact on the worker (examinee user) among the factors included in the cause domain, which are the quantitative and qualitative burden of work. This is because, for example, a question item "I have to always think about work while at work" may be interpreted as applying to oneself even if the situation is not perceived as negative (stressful), making it difficult to clarify the content to be evaluated, whereas, for example, a question item "I can't finish my work in time" clearly reflects the "burden at work" of the person concerned.

[0094] Furthermore, based on statistical data evaluating the impact of work stress on the health of workers, specifically, on data showing that "amount of work / control" and "support from the workplace" have a large impact on health risks, the generating unit 3033 selects, in the cause area, a question item included in "lack of a sense of control," which is one of the factors included in the cause area (for example, the question item "being able to work at one's own pace"), and, in the influencing factor area, selects a question item included in "support from superiors / coworkers," which is one of the factors included in the cause area.

[0095] In addition, in the reaction region, the generation unit 3033 selects each question item from the two factors contained therein.

[0096] In this way, the generation unit 3033 generates a simple questionnaire based on exploratory factor analysis for each of the three areas of causes, reactions, and influencing factors, and the server 300 uses the simple questionnaire and an evaluation method for it, thereby enabling the test-taker user's level of stress to be evaluated simply and appropriately.

[0097] <Modification of the second embodiment> A modified example of the second embodiment will be described. In the above-mentioned second embodiment, an example was described in which the generation unit 3033 generates a simplified questionnaire based on exploratory factor analysis for each of the three areas of cause, reaction, and influencing factor. In contrast, in this modified example, the generation unit 3033 generates a simplified questionnaire by deductively selecting questions from a standard questionnaire (a questionnaire having 57 questions) based on theoretical and clinical experience.

[0098] At this time, the generation unit 3033 may select questions by referring to previous research that has measured similar concepts in the past, may select questions based on the theory assumed behind the concept to be measured, or may select questions based on experience in the field (industrial or medical fields).

[0099] Furthermore, the generating unit 3033 may perform exploratory factor analysis in addition to such a priori selection based on theoretical and clinical experience.

[0100] <Other Modifications> The above embodiment is merely an example, and the present disclosure may be modified as appropriate without departing from the spirit and scope of the present disclosure. For example, the processes and means described in the present disclosure may be freely combined and implemented as long as no technical contradiction occurs.

[0101] Furthermore, the processing described as being performed by one device may be shared and executed by a plurality of devices. For example, the acquisition unit 3031 and the evaluation unit 3032 may be formed in separate arithmetic processing devices. In this case, these arithmetic processing devices are configured to be able to cooperate with each other suitably. Furthermore, the processing described as being performed by different devices may be executed by one device. In a computer system, the hardware configuration (server configuration) by which each function is realized can be flexibly changed.

[0102] The present disclosure can also be realized by supplying a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors of the computer read and execute the program. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (floppy disk, hard disk drive (HDD), etc.), an optical disk (CD-ROM, DVD disk, Blu-ray disk, etc.), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, and any type of medium suitable for storing electronic instructions.
