Description

Technical Field

[0001] The present invention belongs to the technical field of mental health assessment, and specifically relates to a multi-dimensional psychological test assessment method and system based on an adaptive algorithm. Background Art

[0002] According to the "China National Mental Health Development Report (2019-2020)", about 15% of the population in my country belongs to the high-risk group for depression. In comparison, the mental health problems of low-income, low-educated, and unemployed people are particularly prominent. In the current complex social environment, people face many opportunities and challenges, are under great psychological pressure, and may face various risks at any time. If problems arise and are not identified and paid attention to in a timely manner and the best time for intervention is missed, it will often cause immeasurable losses to the individual, the family, and even the entire society. Therefore, scientifically assessing the mental health level of the general public plays a vital role in understanding the mental health needs of various groups and subsequent targeted services.

[0003] Due to the defects of traditional psychological assessment tools, such as large number of questions, time-consuming and labor-intensive, high surface validity, and assessment errors caused by subject fatigue and concealment, it is difficult to promote and apply mental health screening and assessment on a large scale. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, improve the efficiency of mental health screening, and enhance the pertinence and effectiveness of assessment, the present invention provides a multi-dimensional psychological test assessment method and system based on an adaptive algorithm.

[0005] The specific scheme is as follows:

[0006] On the one hand, the present invention provides a multi-dimensional psychological test evaluation method based on an adaptive algorithm, and the method adopted is as follows:

[0007] Step 1: Create an assessment question bank containing a variety of questions;

[0008] Step 2, assigning multi-dimensional mental health variables to each question branch contained in each question in the assessment question bank according to the semantic information of each question;

[0009] Step 3, according to the occupations and life situations familiar to the test subject, the psychological test answer questions of each dimension are matched in the test question bank in the order of the set test dimensions;

[0010] Step 4: When the subject answers the psychological test questions of the current dimension, if the subject reaches the set number of times of selecting the same psychological health variable question, the psychological assessment of the current dimension is terminated;

[0011] Step 5: Analyze the selected branches included in all the answered questions of the measured psychological dimensions to determine whether to continue pushing questions from the test question bank for the next dimension of psychological assessment until the requirements of Step 4 are met, at which point the psychological assessment for the next dimension ends.

[0012] Step 6: Repeat Step 5 until all dimensions of the psychological assessment of the subject are completed or the set number of answered questions is reached, at which point the psychological test task ends and a psychological assessment conclusion is given.

[0013] Furthermore, the multi-dimensional mental health variables assigned to each branch of each question in Step 2 include psychological aspects or psychological variables that reflect the subject's personality type, emotional state, and functional level, and each psychological aspect or psychological variable is set with a fixed identification code.

[0014] Furthermore, in Step 3, first conduct a psychological test on the subject according to the personality type assessment dimension, and then conduct a psychological test analysis of the emotional state and a functional level assessment in sequence.

[0015] Furthermore, in Step 4, when conducting a psychological test on the subject in the personality type assessment dimension, the question-pushing method used is as follows:

[0016] Step 4.1: Randomly push answered questions containing personality type branches from the test question bank to the subject.

[0017] Step 4.2: When the subject first selects a branch of a certain personality type in the answered questions, continue to randomly push unextracted answered questions corresponding to the branches of the same personality type as the first selected one from the test question bank.

[0018] Step 4.3: If the subject selects a branch of the same personality type again in the answered questions, record and confirm the subject's personality type, and end the personality type test.

[0019] Step 4.4: If the subject does not select a branch of the same personality type in the answered questions, record the personality type selected by the subject.

[0020] Step 4.5: Continue to randomly push unextracted answered questions corresponding to the branches of the same personality type as the currently selected one from the test question bank for the subject to answer.

[0021] Step 4.6: Until there are two selections of branches of the same personality type or all personality types are screened, end the personality type test.

[0022] Further, the response questions pushed in step 4.1 include multiple branch options with different personality types and a confusing option or blank item without personality type meaning; if in step 4.4, the subject selects the confusing option or blank item in the response questions, then response questions corresponding to the branches with the same personality type as the previously selected branch are continuously pushed from the evaluation question bank, or response questions corresponding to the branches with different personality types from the previously selected branch are randomly pushed from the evaluation question bank.

[0023] Further, in step 4.3, the response questions with the same personality type selected twice include: continuously selecting the branches of the same target personality type twice when pushing response questions containing branches of the same personality type, or the branches of the same personality type are selected twice for the first time among the answered questions.

[0024] The psychological test of the emotional state includes a depression emotional state test and an anxiety emotional state test.

[0025] In step 5, after the personality type test is completed, the selected branches in all the answered questions are analyzed, and the branches with the emotional state evaluation dimension are selected. If the branches of the same emotional state are selected a set number of times, the test of the emotional state evaluation dimension ends; otherwise, questions are randomly pushed according to the psychological aspects or psychological variables expressed by the selected emotional state branches until the branches of the same emotional state are selected a set number of times or all the set emotional state evaluation dimensions are screened, and then the test of the emotional state evaluation dimension ends.

[0026] The psychological evaluation conclusion given in step 6 includes the evaluation conclusions of the emotional state, personality type, and corresponding functional levels.

[0027] On the other hand, the present invention also provides a multi-dimensional psychological test and evaluation system based on an adaptive algorithm. The system includes: a mobile terminal and an evaluation question bank, a multi-dimensional psychological evaluation module, a question-pushing algorithm module, and an evaluation analysis module running in the mobile terminal;

[0028] The evaluation question bank contains evaluation questions with several question numbers, and each evaluation question consists of several branch options;

[0029] The multi-dimensional psychological evaluation module. Each psychological evaluation module includes several mental health variable sub-modules. Each mental health variable sub-module includes multiple branches. Each branch corresponds to the evaluation question of the corresponding question number in the evaluation question bank, and the branches included in the same mental health variable sub-module are given the same psychological aspect or psychological variable;

[0030] The question-pushing algorithm module extracts, in real time according to the selected option branches in the previous assessment question by the test taker and in accordance with the set question-pushing algorithm, the assessment questions corresponding to the option branches in the mental health variable sub-module for the test taker to answer;

[0031] The assessment and analysis module analyzes all the selected option branches in the questions already answered by the test taker, forms a multi-dimensional psychological test assessment conclusion, and outputs it through the mobile terminal.

[0032] Furthermore, a basic information registration module is also stored in the mobile terminal, which is used to record the basic information of the test taker such as gender, age, marital status and occupation. The question-pushing algorithm module extracts the basic information registered by the test taker from the basic information registration module, and extracts the answering questions matching the occupations and life situations familiar to the test taker from the assessment question bank.

[0033] Preferably, the multi-dimensional psychological assessment module includes a personality type detection module, an emotional state detection module and a functional level detection module. There are 4 - 13 personality type variable sub-modules based on personality type tests in the personality type detection module, 4 depression variable sub-modules based on depression state tests and 3 anxiety variable sub-modules based on anxiety state tests in the emotional state detection module; there are 3 functional level variable sub-modules based on functional level detection in the functional level detection module, and each option branch included in all the assessment questions in the assessment question bank is assigned a functional level.

[0034] The technical solution of the present invention has the following advantages:

[0035] A. The present invention breaks the focused idea of evaluating a single dimension by a single question in traditional assessments, allows users to make selections in one scenario (question), and the same option branch in each assessment question reflects the characteristics of the individual on multiple psychological aspects or psychological variables (personality type, emotional characteristics, mental health indicators, functional status, etc.). Without compromising the accuracy of the assessment, it maximizes the use of the semantic information of the assessment questions, improves the efficiency of psychological assessments, and completes a more comprehensive assessment of users with fewer questions.

[0036] B. The present invention can, in ways such as based on user characteristics, real-time interaction during answering, and adaptive algorithm question-pushing, automatically generate a customized questionnaire (about 30 - 45 questions) with the highest personal matching degree for the test taker from nearly a thousand questions in multiple test question banks. In only about 15 minutes, it can present a complete screening and assessment of multiple mental health indicators and dimensions such as mental health and emotional health, and provide professional, content-rich assessment reports, risk warnings and countermeasure suggestions for organizations and individuals.

[0037] C. In the internal logic design of the assessment questions of the present invention, a progressive mode of "general traits to individual traits" and "major categories to sub-categories" is adopted. As the user progresses through the answering order, the assessment question bank will perform real-time matching of the answered questions, gradually locking in the most suitable differential questions for the user, and finally presenting a customized assessment effect, improving the pertinence and effectiveness of the assessment.

[0038] D. Based on the basic information registered by the test taker, the present invention extracts from the assessment question bank scenarios that are familiar to the test taker in terms of occupation and life, and buries the function of mental health screening into the scenario-based questions. The questions are directed towards life scenarios, making it difficult to conceal and disguise answers, making the present invention more localized. The questions and answer options are set to be more in line with Chinese national conditions and culture, having a more efficient and accurate screening ability.

[0039] E. The present invention is highly adaptable, efficient, agile, and flexible, enabling more citizens to obtain professional psychological assessments, contributing to the construction of social psychological services, and solving problems such as a large number of service objects and significant background differences limited by resources.

[0055] Preferably, the present invention first conducts a psychological test on the test taker according to the personality type evaluation dimension, and then sequentially conducts psychological test analysis of the emotional state and evaluation of the function level. Of course, other orders of psychological tests can also be set, which are not specifically limited in the present invention and are all within the protection scope of the present invention.

[0064] The two selections of answering questions of the same personality type in the above steps include: continuously selecting branches of the same target personality type twice when pushing answering questions of the same personality type, or the first appearance of two selections of branches of the same personality type in the answered questions.

[0065] There are 13 personality types set in the present invention, and their identification codes respectively correspond to the following semantic meanings:

[0066] Pd-1 Pd-2 Pd-3 Pd-4 Pd-5 Pd-6 Pd-7 Antisocial Borderline Paranoid Schizotypal Schizoid Passive-Aggressive Narcissistic Pd-8 Pd-9 Pd-10 Pd-11 Pd-12 Pd-13 Histrionic Avoidant Dependent Obsessive-Compulsive Depressive Psychopathic

[0067] The following takes Figure 4 as an example to illustrate the specific question-pushing algorithm.

[0068] Figure 4 The question-pushing algorithms involved in include four personality types, namely Pd-1: Antisocial type, Pd-2: Borderline type, Pd-3: Paranoid type, Pd-13: Psychoticism.

[0069] When a subject answers the questions pushed by the assessment question bank, if the branch of Pd-1 type is selected, other questions corresponding to the branch of Pd-1 type are randomly pushed from the assessment question bank. For the other branch options in this question, 3 branches of the remaining types can be selected from the remaining branches included in this question, and then 1 option of "none of the above" is selected, or 2 branches of the remaining types are selected, and then 1 confusing option and 1 option of "none of the above" (i.e., the blank option) are selected to form a five-choice single-choice answering question containing Pd-1. The selection of all branches is randomly selected by the system. If the subject further selects the branch option with the Pd-1 identification code, it is confirmed that the subject's personality type is positive, and the personality type test can be ended. Otherwise, if the subject does not select the branch option with the Pd-1 identification code but selects the branch option with the Pd-2 identification code, the system should push the question number corresponding to the branch option with the Pd-2 identification code from the assessment question bank and randomly combine it into a new answering question with five branch options containing the Pd-2 identification code to further confirm the subject's choice. According to the principle of confirming the personality type by selecting twice in the figure, the subject's personality type is determined. Otherwise, it is determined that the subject's personality type is negative, which is the normal personality type.

[0070] Of course, during the subject's answering process, it is possible to select "none of the above" or the confusing option. In this case, the system continues to push the answering questions corresponding to the branches with the same personality type as the previously selected branch from the assessment question bank, or randomly pushes the answering questions corresponding to the branches with different personality types from the previously selected branch from the assessment question bank. The specific question-pushing method can be set according to the test procedure and will not be elaborated here.

[0071] In the present invention, when the answering question corresponding to the branch of a certain personality type is first selected, it is necessary to further confirm whether the subject really belongs to this personality type, and then continue to push the question numbers corresponding to the other branch options with the same personality type as the previously selected branch and form a new answering question. The previously answered questions will not be pushed again. If the subject does not select the branch option with the same personality type again, the personality type expressed by the currently selected branch option is used as a reference, and the questions corresponding to the branches with the same personality type as the previous selected branch option are further pushed for answering. After the answering is completed, a comprehensive analysis of all the previously selected branch situations is also carried out. If the answering questions corresponding to the other branch options with the same personality type were selected previously, the subject's personality type is confirmed, that is, the personality type detection is completed.

[0072]

[0073] After the personality type test is completed, analyze all the answered questions, select the answered branches with the emotional state assessment dimension that have been selected. If the same emotional state branch is selected twice, end the test for the emotional state assessment dimension; otherwise, randomly push questions according to the psychological aspects or psychological variables expressed by the selected emotional state branches until the same emotional state branch is selected twice or all the screening of the set emotional state assessment dimensions is completed, and then end the test for the emotional state assessment dimension.

[0074] If, after analyzing the answered questions, branches of the same depressive state and the same anxiety state are not selected twice, it is necessary to further detect the emotional state. Specifically, as Figures 5 to 9 is the calculation description of the depressive state detection module. Figures 10 to 12 is the calculation description of the anxiety state detection module.

[0075] The principles of psychological test assessment for the depressive state and the emotional state are the same as those for the personality type. The system can push questions with reference to the branches of an emotional state selected for the first time or the last time, or randomly push the questions corresponding to the branches of a certain emotional state for answering. The present invention does not specifically limit this.

[0076]

[0077] The present invention can, in ways such as based on user characteristics, real-time interactive answering, and adaptive algorithm question pushing, automatically generate a customized questionnaire (about 30 - 45 questions) with the highest personal matching degree for the subject from 33 sub-question banks and nearly a thousand questions. In only about 15 minutes, it can present a complete screening and evaluation of various mental health indicators and dimensions such as mental health and emotional health, and provide professional, content-rich assessment reports, risk warnings, and countermeasure suggestions for organizations and individuals.

[0078] As Figure 14 shown, the present invention also provides a multi-dimensional psychological test assessment system based on an adaptive algorithm, including a mobile terminal and a test question bank, a multi-dimensional psychological assessment module, a question pushing algorithm module, and an assessment analysis module running on the mobile terminal.

[0079] Among them, the test question bank is as Figure 2and Figure 3 As shown, there are several assessment questions with numbers, and each assessment question consists of several option branches.

[0080] The multi-dimensional psychological assessment module. Each dimension of the psychological assessment module contains several sub-modules of mental health variables. Each sub-module of mental health variables contains multiple option branches (or options). Each option branch corresponds to the assessment question (or stem) with the corresponding question number in the assessment question bank. And the option branches included in the same sub-module of mental health variables are given the same psychological aspect or psychological variable; that is, the question number corresponding to each option branch is unique. For example Figure 2 and Figure 3 As shown, multiple option branches can be set under one question. For example Figure 3 In the question with question number 98 in , there are 10 option branches. For example, extract four of the option branches, and add an option of "none of the above" to form a response question composed of five randomly selected option branches. Of course, among the option branches, there are also option branches without identification codes. This kind of option branch can be used as a confounding item to participate in the response question. For example Figure 2 or Figure 3 as shown in .

[0081] The question-pushing algorithm module extracts the assessment questions (or question numbers) corresponding to the option branches in the sub-module of mental health variables in real time according to the response of the test taker to the previous assessment question, according to the set question-pushing algorithm, for the test taker to answer; the tested assessment questions will not be extracted and pushed in subsequent assessments. The present invention preferably conducts two confirmations for the same psychological assessment dimension. Of course, three or more repeated tests can also be set according to specific situations. The more times of confirmation are set, the more response questions need to be pushed, and the relatively longer the response time is.

[0082] The assessment analysis module comprehensively analyzes all the questions that the test taker has answered, forms a multi-dimensional psychological test evaluation conclusion, and outputs it through the mobile terminal for the test taker to view.

[0083] In order to enable the system to timely master the basic situation of the test taker, the present invention also stores a basic information registration module in the mobile terminal, which is used to record the basic information of the test taker such as gender, age, marriage and occupation. The question-pushing algorithm module extracts the basic information registered by the test taker from the basic information registration module, and extracts response questions that match the occupations and life situations familiar to the test taker from the assessment question bank. Of course, multiple related questions can also be set in the same situation. Each question contains multiple option branches that need to detect the psychological aspects or psychological variables of the test taker, so that the test taker can more easily integrate into the situation environment, show the true psychological state of the test taker, and obtain a more accurate test evaluation conclusion.

[0084] The multi-dimensional psychological assessment module adopted by the present invention includes a personality type detection module, an emotional state detection module, and a functional level detection module. The personality type detection module is provided with 4-13 personality type variable sub-modules based on personality type tests, specifically including: any combination of four or more of the anti-social type sub-module, the borderline type sub-module, the paranoid type sub-module, the schizotypal type sub-module, the schizoid type sub-module, the passive-aggressive type sub-module, the narcissistic type sub-module, the histrionic type sub-module, the avoidant type sub-module, the dependent type sub-module, the obsessive-compulsive type sub-module, the depressive type sub-module, and the psychoticism type sub-module.

[0085] The emotional state detection module is provided with four depression variable sub-modules based on depression state tests and three anxiety variable sub-modules based on anxiety state tests; among the depression variable sub-modules, there are the anhedonia sub-module, the depressed mood sub-module, the low self-worth sub-module, and the sense of meaninglessness sub-module; among the anxiety variable sub-modules, there are: the sympathetic nervous symptom sub-module, the uneasiness sub-module, and the catastrophic cognition sub-module, which are respectively represented by An-1, An-2, and An-3 in Figures 10 to 12 ; each sub-module involves several question branches corresponding to the psychological aspect or psychological variable.

[0086] The functional level detection module is provided with three functional level variable sub-modules based on functional level detection, and each question branch included in all the assessment questions in the assessment question bank is assigned a functional level, such as Figure 2 and Figure 3 shown. Among them, the functional level variable sub-modules include the high-function sub-module, the medium-function sub-module, and the low-function sub-module, which respectively contain question branches with different functions, and Fu-1 represents high function, FU-2 represents medium function, and FU-3 represents low function in the question branches respectively, and a comprehensive evaluation can be carried out in combination with the functional level of the selected question branches.

[0087] As Figure 13 shown, analyze all the selected question branches, and successively conduct the determination of low function, medium function, and high function. When a function is confirmed, the assessment of this dimension is ended. The determination methods for low, medium, and high functional levels are as follows:

[0088] Among them, the low function determination: n1 / N1≥30%

[0089] n1 - the selected frequency of the low-function question branch options

[0090] N1 - the number of questions with low-function question branch options among the answered questions

[0091] The medium function determination: n2 / N2≥30%

[0092] n2 - the selected frequency of the medium-function question branch options

[0093] N2-The number of questions with middle function options in the answered questions

[0094] Installation judgment: n3 / N3≥90%

[0095] n3- Frequency of selection of high-function topic options

[0096] N3-The number of questions with high-functioning branch options among the answered questions.

[0097] When the result does not belong to the fitted result, the subject is judged to be at a high functional level.

[0098] Of course, the present invention is not limited to the psychological tests of several dimensions as exemplified above, and psychological aspects or psychological variables of other dimensions can also be given to the question options on this basis, such as Figure 2 and Figure 3 Add psychological tests on interpersonal patterns.

[0099] The present invention automatically infers questions and detects the personality type, depressive traits and anxious traits of the subject in turn from the assessment question bank according to the established inferring method, and generates a profiling report.

[0100] The present invention breaks the focus of traditional assessments in which one question evaluates a single dimension, and allows users to make choices in a situation (question). The same question branch in each assessment question reflects the characteristics of the individual in multiple psychological aspects or psychological variables (personality type, emotional characteristics, mental health indicators, functional status, etc.). The questions are close to life scenes and are not easy to conceal or disguise in answers, making the present invention more localized. The setting of questions and question branches is more in line with Chinese customs and culture. The questions set maximize the use of the semantic information of the assessment questions without compromising the accuracy of the assessment, thereby improving the efficiency of psychological assessment and completing a more comprehensive evaluation of users with fewer questions.

[0101] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
