DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0010] FIG. 1 is a diagram showing an example of the configuration of a task support system 10 (hereinafter, simply referred to as "system 10") according to an embodiment. The task support system 10 is a system mainly intended to provide task support for registered dietitians who perform nutritional guidance tasks for subjects of nutritional guidance. In the system 10, the terminal used by the registered dietitian is a nutritionist terminal 110, and the task support server 100 provides various information related to task support to the nutritionist terminal 110, thereby supporting the task of the registered dietitian. Therefore, the system 10 is configured as a minimum configuration in which the task support server 100 and the nutritionist terminal 110 are connected via a network 120. Although FIG. 1 shows a state in which only one nutritionist terminal 110 is connected, this is merely an example, and a large number of nutritionist terminals 110 can be connected to the network 120 and information can be provided from the task support server 100.

[0011] The business support server 100 transmits screen information required for the registered dietitian to perform nutritional guidance work on the nutritionist terminal 110 to the nutritionist terminal 110, and executes processing according to the input contents by the registered dietitian. The nutritionist terminal 110 is a terminal used by the registered dietitian, and the registered dietitian provides nutritional guidance to a subject of nutritional guidance (hereinafter simply referred to as "subject") according to the information provided from the business support server 100 to the nutritionist terminal 110.

[0012] The network 120 is a communication means for connecting the task support server 100 and the dietitian terminal 110, and may be, for example, the Internet, or may be a network that can be accessed only within a specific organization, such as an intranet.

[0013] Next, an example of the hardware configuration of the business support server 100 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the hardware configuration of the business support server 100. The business support server 100 can be configured to include, for example, a CPU 201, a ROM 202, a RAM 203, a bus 204, an input / output interface 205, an output unit 206, an input unit 207, a storage unit 208, a communication unit 209, and a drive 210.

[0014] The CPU 201 executes a program recorded in the ROM 202 or a program loaded from the storage unit 208 to the RAM 203 to execute various processes corresponding to this embodiment. The RAM 203 functions as a work area for the CPU 201, and also stores data and the like necessary for the CPU 201 to execute various processes as appropriate. The CPU 201, the ROM 202, and the RAM 203 are connected to each other via a bus 204. An input / output interface 205 is also connected to the bus 204, and an output unit 206, an input unit 207, a storage unit 208, a communication unit 209, and a drive 210 are further connected via the input / output interface 205.

[0015] The output unit 206 is composed of a display, a speaker, etc., and outputs various information as images and sounds. The input unit 207 is composed of a keyboard, a mouse, a touch panel, etc., and can input various information. The storage unit 208 is composed of a hard disk, a DRAM, etc., and stores various data including a processing program corresponding to this embodiment. The storage unit 208 stores information on a subject table that registers information on subjects of nutritional guidance, a table 400 that registers a question list, and a table 410 that registers guidance information, which will be described later in relation to Figures 3 to 5. The communication unit 209 communicates with other devices (dietitian terminal 110 in the example of Figure 1) via the network 120. A storage medium 211 consisting of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately mounted in the drive 210. A program read from the storage medium 211 by the drive 210 is installed in the storage unit 208 as necessary. In addition, the storage medium 211 can store various data stored in the storage unit 208 in the same manner as the storage unit 208.

[0016] The dietitian terminal 110 may also have a hardware configuration similar to that shown in FIG.

[0017] Next, the flow of processing corresponding to this embodiment will be described with reference to Fig. 3. Fig. 3 is a timing chart showing the flow of processing in the task support system 10 corresponding to this embodiment. This processing is realized by the task support server 100 and the dietitian terminal 110 executing corresponding processing programs by the CPU, or by the CPU controlling the operation of functional blocks such as the output unit 206, input unit 207, storage unit 208, and communication unit 209 shown in Fig. 2.

[0018] In nutritional guidance, in order to achieve behavioral change in the subject of nutritional guidance, it is not enough to simply give the subject knowledge. It is important to appropriately evaluate the subject's attitude and motivation through dialogue, and to approach them in a way that suits them while sharing correct information and encouraging behavioral change. However, dietitians with little experience in the field are not always able to properly evaluate the subject's attitude and motivation, and may take the wrong approach. An incorrect approach may lead to the subject dropping out of lifestyle-related disease prevention and treatment. Lifestyle-related diseases such as diabetes, high blood pressure, and dyslipidemia are caused by poor eating habits and lack of exercise, and there is a risk of developing life-threatening complications, so they are diseases that must be addressed immediately. Therefore, it is important for dietitians to take an appropriate approach to the subject and guide them to continue lifestyle-related disease prevention and treatment.

[0019] Therefore, a method is provided that enables even a dietitian with little field experience to take an appropriate approach to a subject. In this embodiment, the subject's motivation and attitude are quantified by a number of questions to determine the subject's psychological level, and an approach is made according to the subject's mental state based on the determined psychological level, thereby improving the feasibility of behavioral change. The process flow in this embodiment is explained below according to the steps in FIG. 3.

[0020] First, in S301, the dietitian terminal 110 accepts input of information on the subject from the registered dietitian. The subject's information includes the name, date of birth, and other personal information. This information is managed in association with identification information (user ID) for uniquely identifying the subject. In the case of a registered subject, the subject and the information can be specified by inputting the user ID.

[0021] The subject information or user ID entered in S302 is sent from the dietitian terminal 110 to the business support server 100. In the business support server 100, based on the subject information received from the dietitian terminal 110, the subject information is searched for in the subject table stored in the storage unit 208. If the subject is new, no information is found, and the process proceeds directly to S304. If the subject is already registered, the results of the previous instruction (particularly information on the determined psychological level) are registered in the subject table, so this information is read out and the process proceeds to S304.

[0022] In S304, a list of questions to be asked to the subject (question list) is created in the business support server 100. For subjects receiving nutritional guidance for the first time, a question list for the initial guidance is created, and for subjects who are already registered, a question list is created based on information on the psychological level of the previous guidance. A question list table 400 is registered in the memory unit 208 of the business support server 100, and a question list for the initial guidance and a question list according to the subject's level may be read from the table 400 and created.

[0023] The questions included in the question list are mainly related to one of six items, namely, consciousness change, behavior change, current status grasp, sense of crisis, motivation, and dissonance. The number of questions can be equal for each of the five items excluding dissonance. Alternatively, the scores are allocated so that there is at least no variation in the scores for each item. The question list includes a question list for the first instruction and a question list corresponding to the psychological level determined last time. Since the question list for the first instruction cannot evaluate consciousness change and behavior change, the five items of questions are used to evaluate the current status grasp, sense of crisis, and motivation, and to separately evaluate dissonance. In this embodiment, the psychological level is determined in four stages from level 1 to level 4, so at least five types of question lists are created. In addition, the question list when the previous level was 2 or more may be common. In that case, three types of question lists are created for the first instruction, previous level 1, and previous level 2 or more.

[0024] Table 400 in Fig. 4(A) shows an example of the data configuration of a question list table. Table 400 includes a list name 401, questions about changes in awareness 402, questions about changes in behavior 403, questions about the degree of understanding of the current situation 404, questions about a sense of crisis 405, questions about motivation 406, and questions about dissonance 407. For each question, the contents according to the subject's situation, for example, whether it is the first instruction or a determined psychological level, are registered.

[0025] Among the question list, the questions 402 regarding changes in consciousness may include, for example, a question about what prompted the patient to receive the guidance at the first instruction, and from the second instruction onwards, may include questions according to the psychological level, such as changes in consciousness regarding dietary habits since the previous instruction. Also, the questions 403 regarding changes in behavior may include questions according to the psychological level, such as actions and ideas taken regarding dietary habits since the previous instruction.

[0026] The questions 404 regarding the degree of understanding of the current situation can include questions according to the psychological level, for example, about medical history, weight, etc. The questions 405 regarding the sense of crisis can include questions according to the psychological level, for example, about whether or not the patient wants to change the current situation, or about their thoughts about their weight or test results, etc. The questions 406 regarding motivation can include questions according to the psychological level, for example, about whether or not the patient wants to receive dietary support from a registered dietitian, or about the presence or absence of motivation to improve their lifestyle, etc.

[0027] In this embodiment, a question list is prepared with questions for each psychological level, so even an inexperienced registered dietitian can ask questions that match the psychological level of the subject. For example, even if the questions have the same meaning, it may be better to ask the questions in a way that matches the psychological level of the subject, or to ask questions in a different way for each psychological level.

[0028] Specifically, in a question intended to confirm behavior regarding dietary life, at level 1, confirmation is limited to whether the behavior has been performed, whereas at higher levels, the scope of confirmation can be deepened by confirming whether the behavior is being continued, the specific content of the behavior, or whether a new behavior has been performed, etc. In this way, the level of detail of the information expected as an answer can be increased with each increase in level.

[0029] If detailed answers are requested in a situation where the level is low, the act itself puts pressure on the subject, which may lead to the subject abandoning lifestyle-related disease prevention and treatment. When the subject has little experience in the act of questioning itself, it may be difficult to judge how far the subject should go in order to confirm, so by presenting a way of asking questions according to the determined psychological level, it is possible to avoid an incorrect approach. In this embodiment, the question list is created including a way of asking questions according to the psychological level, so a more appropriate approach that matches the psychological level is possible.

[0030] Regarding the question 407 regarding dissonance, for example, it may include a question regarding the presence or absence of concerns, including illness, in daily life. The question may be changed according to the psychological level, or may be common. Dissonance refers to a situation in which the subject feels strong resistance to nutritional guidance or the instructor through the interview, and can be judged by the answer to the question and the attitude at that time.

[0031] When the business support server 100 creates a question list, it transmits the question list to the dietitian terminal 110 in S305. The transmitted information includes the question list and screen information for inputting the evaluation. When the dietitian terminal 110 receives the question list, in S306, the dietitian terminal 110 displays the question list on the display using the screen information. The registered dietitian can ask questions to the subject according to the displayed question list.

[0032] In the next step S307, the dietitian terminal 110 can accept input of an evaluation score for each question according to the answer to the question and the attitude at the time of answering. For example, the evaluation score may be selected from 1 point, 3 points, or 5 points for each question, or a score of 1 point or 5 points may be selected. However, for dissonance, only two options, yes or no, may be used.

[0033] At this time, the dietitian can ask the subject questions while checking the contents of the screen displayed on the dietitian terminal 110, and input evaluation points according to the answers. Six questions, Question 1 to Question 6, are displayed on the screen, and an evaluation point can be input for each question. After the dietitian has finished asking questions and inputting the evaluation points, the input evaluation point information is sent to the business support server 100.

[0034] Returning to the explanation of FIG. 3, in response to clicking the send button 507, in S308, the information is sent from the dietitian terminal 110 to the business support server 100. In S309, when the business support server 100 receives the information on the evaluation points from the dietitian terminal 110, it judges the psychological level of the subject according to the total evaluation points and the result of the presence or absence of dissonance. If it is evaluated that there is a feeling of dissonance, it is judged as level 1 regardless of other evaluation points. If there is no feeling of dissonance, for example, if the total evaluation points for the questions included in the question list is 10 points or less, it can be judged as level 1, if it is 11 points to 15 points, it can be judged as level 2, if it is 16 points to 20 points, it can be judged as level 3, and if it is 21 points or more, it can be judged as level 4. The reference points for level judgment shown here are merely examples, and can be changed according to the number of questions, the total score, and even the teaching performance. The above threshold value for level judgment is common regardless of age and sex, but the threshold value may be changed according to age and sex.

[0035] In the next S310, the business support server 100 generates guidance information according to the determined level, and in S311, the business support server 100 transmits the guidance information to the dietitian terminal 110. The dietitian terminal 110 displays the received guidance information on a display. The registered dietitian can provide nutritional guidance to the subject according to the displayed guidance information.

[0036] Table 410 in Fig. 4(B) shows an example of the data configuration of the instruction information table. Table 410 includes instruction information name 411, instruction posture 412, instruction content 413, assignment 414, points to note 415, and others 416. A set of information corresponding to the psychological level of the subject is registered in the instruction information. In instruction information name 411, a name indicating which of four psychological levels the instruction information corresponds to is registered. Other items of instruction information may include, for example, the following information.

[0037] The instruction attitude 412 is instruction information on the attitude of the registered dietitian toward the subject, the way of thinking and mental preparation toward lifestyle-related diseases, and the approach to the subject, and the content varies depending on the psychological level of the subject. In particular, for subjects at a low level, points are included to encourage them to continue receiving instruction in the future. Also, even for subjects at a high level, points are included to prevent the condition from relapsing.

[0038] The instruction content 413 includes information such as points to note when instructing the target person, mental preparation, and relationship with the target person.

[0039] Task 414 provides examples of tasks to be completed before the next instruction depending on the level of the recipient. At level 1, the continuation of nutritional guidance is given top priority, and simple tasks that lead to this are presented. From level 2 onwards, small tasks that can be completed without significantly changing the recipient's lifestyle are presented. It is also possible to gradually increase the burden of the tasks as the level increases. Alternatively, you can work together to set tasks that meet the recipient's requests.

[0040] The points to be careful about 415 include information on things that should not be done, things to be considered, and points to be careful about when giving guidance to the target. For example, level 1 patients often speak of lifestyle habits and thoughts that are generally not considered good, but rather it is important to accept them rather than immediately correcting them. It also includes information on the way of thinking and mindset of the registered dietitian when giving guidance. For example, when it comes to bad lifestyle habits and ways of thinking, consider the causes and background of why such habits and ways of thinking exist. It also includes points to be careful about regarding the distance from the target.

[0041] Other 416 includes any other information not included in instructional information 412-415 above.

[0042] According to the above embodiment, the registered dietitian can assign evaluation points based on the subject's answers to the questions included in the question list, or the subject's attitude when answering, and determine the psychological level based on the total score.

[0043] In this embodiment, the psychological level is set with reference to the transtheoretical model, which is a theory that shows that a person's behavior changes and is maintained through five stages, namely, the indifference stage, the interest stage, the preparation stage, the execution stage, and the maintenance stage, and that the effective method of influencing the subject varies depending on which stage the subject is currently in.

[0044] In this embodiment, the psychological level is set in four stages from level 1 to level 4, with level 2 corresponding to the preparation stage, level 3 corresponding to the execution stage, and level 4 corresponding to the maintenance stage, while level 1 includes both the indifferent stage and the interested stage. Subjects in the indifferent stage and the interested stage have in common a strong resistance to behavioral change, and the dietitian's response method is the same, so they are all categorized as level 1.

[0045] Here, the indifferent stage of level 1 refers to a state where the patient does not understand that behavioral change is necessary and has no motivation, while the interested stage refers to a state where the patient vaguely understands that behavioral change is necessary but has no motivation. Subjects who fall into level 1 are in a state where they "won't do it even if they are told," and the more something is pointed out to them, the more resistant they tend to be. Factors contributing to this include a low importance attached to behavioral change, low confidence, and an immature relationship of trust with the instructor, and they are at the highest risk of dropping out of nutritional guidance.

[0046] Level 2, the preparation stage, refers to a state in which it is known that behavioral change is necessary and people want to do it, but they do not act voluntarily. Subjects who fall into level 2 are in a state of "I will do it if I'm told, but I won't do it voluntarily," and although the importance of behavioral change has increased slightly, their confidence in carrying it out is still low. They are also at the stage where they are starting to build a relationship of trust with their instructor little by little, so they will try if asked to do it, but once they fail, there is a high possibility that they will drop out.

[0047] Level 3, the action stage, refers to a state in which the person acts spontaneously but is not independent and requires support. Subjects who fall into level 3 are in a state of "acting spontaneously but not independently," and with support they can get by with their own ingenuity, but are likely to drop out if support is removed. They are gaining confidence and behavioral change is becoming a habit, but they are in an unstable state where some events can shake their habits and cause them to revert (revert to a lower level).

[0048] The maintenance stage of level 4 refers to a state where the subject is acting voluntarily and is independent, so that the nutritional guidance can essentially be terminated. Subjects who fall into level 4 are in a state of "acting voluntarily and being independent" and can operate independently without support. At the level 4 stage, results are being seen, and behavioral changes often become habitual without the subject realizing it.

[0049] As described above, in this embodiment, when a lifestyle improvement proposal is made to a subject, the subject's psychological level is first determined, and guidance information according to the determined psychological level is provided, so that the subject's behavior can be promoted according to the subject's condition. The guidance information can make up for the lack of experience and knowledge of the registered dietitian in how to treat the subject, so that the nutritional guidance by the registered dietitian can more efficiently lead to the improvement of the subject's lifestyle, and the subject's behavior can be promoted in a step-up manner with each nutritional guidance session. In addition, it is possible to prevent the subject from abandoning lifestyle-related disease prevention and treatment, and to increase the possibility of behavioral change.
