  However, in the system disclosed in Patent Document 1 described above, since the psychological examination is performed by asking a number of question items, the examination time becomes long and the burden on the examinee increases. was there. Further, in Patent Document 1 described above, since the same question item is repeatedly used, the inspected person learns the tendency of the question, and there is a concern that the reliability and validity of the examination may be reduced. In particular, if the number of question items is simply reduced, the person to be inspected memorizes the question items, and the decrease in inspection accuracy due to the learning effect becomes significant.

  Therefore, the present invention has been made in view of the above points, and a psychological examination system and a psychological examination method capable of shortening the examination time without reducing the reliability and validity of the examination when performing a psychological examination. The issue is to provide.

  In order to solve the above-mentioned problem, the present invention groups the question items for performing a psychological examination on the network according to the characteristics and accumulates them in the item pool unit, and stores the group items stored in the item pool unit. From each, a predetermined number of question items are arbitrarily selected and extracted, psychological test information is generated by the test information generation unit based on the extracted question items, and sent and received through the data transmitting and receiving unit that transmits and receives data through the communication network. Present test information and get answers from users.

  According to the present invention, a plurality of question items having the same characteristics are grouped and accumulated in the item pool part, and a necessary number of question items are extracted from the group to create an inspection problem (inspection information). And conduct the inspection. For this reason, by reducing the number of question items, the inspection time can be shortened and the burden on the inspected person can be reduced, and the required number of question items are set for each characteristic, resulting in a decrease in inspection accuracy. There is no.

  In the above invention, in the grouping in the item pool part, a characteristic that does not depend on the group is set, the characteristic of the question item is described by a numerical value that can be compared such as difficulty level and discriminating power, and the characteristic satisfies a certain reference value. It is preferable to set a plurality of question items. In this case, so-called item response theory is applied to group the question items, so that they are not affected by the characteristics of the examinee population, such as the average value or standard deviation, and are based on general characteristic values. The question items can be classified, and the inspection accuracy is not lowered even if the number of question items is reduced.

  As described above, according to the present invention, when a psychological test is performed, the test time can be reduced without reducing the reliability and validity of the test by reducing the number of question items by applying item reaction theory or the like. Can be shortened, and the burden on the examinee can be reduced.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a schematic configuration of a psychological examination system according to the present embodiment.

  As shown in the figure, the psychological examination system according to the present embodiment is roughly configured by user terminals 11 to 13 that can be connected to the Internet 2 and a Web server 3 arranged on the Internet 2.

  These user terminals 11 to 13 can transmit and receive data to and from the Web server 3 by a browser function. The browser function is realized by application software for browsing Web pages. It downloads HTML (HyperText Markup Language) files, image files, music files, etc. from the Internet, analyzes the layout, and displays / plays them. With this browser function, it is also possible for the user to transmit data from the user terminals 11 to 13 to the Web server using the form, or to operate application software described in various computer languages.

  The Internet 2 is a distributed communication system constructed by connecting various communication lines (public lines such as telephone lines, ISDN lines, ADSL lines, private lines, and wireless communication networks) using the communication protocol TCP / IP. This communication network includes a LAN such as an intranet (company network) or a home network based on 10BASE-T or 100BASE-TX.

  The Web server 3 is a server computer that transmits information such as an HTML file, an image file, and a music file in a document system such as the World Wide Web (WWW) or software having a function thereof. This information is transmitted through an IP network such as the Internet 2 in response to a request from client software such as a Web browser.

  Specifically, the Web server 3 includes a data transmission / reception unit 31 that transmits and receives data via the Internet 2, an item pool 32 that accumulates question items, an item extraction unit 34, and inspection information that creates inspection information (inspection sheet). A generation unit 35, a test execution unit 36 that executes a psychological test, and a user database 39 that accumulates test results are provided. The “module” used in the following description is a functional unit for achieving a predetermined operation, which is configured by hardware such as a device or equipment, software having the function, or a combination thereof. Indicates.

  The data transmission / reception unit 31 is a module that transmits a web page to the browser software on the user side through the Internet 2 by using a protocol such as HTTP (HyperText Transfer Protocol), for example, and receives data input in the browser software. Specifically, the inspection information generated by the inspection information generating unit 35 is transmitted to the user terminals 11 to 13, the response data input on the user terminals 11 to 13 side is received, and the received response data is received. The data is input to the inspection execution unit 36.

  The user database 39 is a database device that accumulates personal information of a user who is an examinee, authentication information such as a user ID and password, name, age, address, etc., psychological test response data, psychological test results As a record for each user. Note that the examination results of the psychological examination accumulated in the user database 39 can be examined based on data specifying the user such as a user ID and a name. The answer data stored in the user database 39 is output in response to a request from the item pool update unit 37 and can be aggregated in the item pool update unit 37.

  The item pool 32 is a database device that accumulates question items to be asked in the psychological examination as text data. Each question item is classified according to its characteristics and is stored in groups 331 to 33n for each characteristic. In this embodiment, each group stores, for example, six or more question items Q1 to Q6. Then, the item pool 32 outputs necessary question items to the item extraction unit 34 in response to a request from the item extraction unit 34.

  The item extraction unit 34 randomly selects and reads out a predetermined number (for example, two items) of question items from the question items Q1 to Q6 respectively stored in the groups 331 to 33n in the item pool 32. This is a module for outputting the question items to the examination information generating unit 35.

  The inspection information generation unit 35 is a module that generates an inspection sheet based on the question item selected by the item extraction unit 34. Specifically, the inspection sheet is generated by embedding the text data of the question item extracted by the item extraction unit 34 in the inspection sheet template formed in a predetermined format.

  The inspection information generation unit 35 may be provided with a function for arbitrarily rearranging the order of question items to be embedded in the template when an inspection sheet is created. In order to rearrange the order of the question items, if there are questions that should be fixed in order or position, the order of the questions may be changed or not. Alternatively, information such as the question position may be added, and embedding into the template may be executed based on this information.

  The inspection execution unit 36 is a module that presents an inspection sheet through the data transmission / reception unit 31 and obtains an answer from the user. Specifically, the response data returned from the user terminals 11 to 13 is received, the response data is analyzed, and the response data and the analysis result are stored in the user database 39 for each user.

The analysis in the examination execution unit 36 is roughly divided into two functions: analysis for individuals and analysis for organizations. For personal analysis, there are seven factors related to stress,
(1) Workplace stressor
(2) Family stressor
(3) Coping (strategies for dealing with stressors)
(4) Psychological stress reaction caused by stressors
(5) Social support to assist parties in stress
(6) Social skills for interpersonal response
(7) Based on job satisfaction, analyze the stress status of individual units from multiple angles. Specifically, questions about 56 questions extracted by the item extraction unit 34 in relation to the above stress-related factors are presented to the user, and how much is applicable to 5 levels (not applicable at all, not much applicable, Answer by selecting from “None”, “Slightly applicable, Well applicable”.

  Further, the Web server 3 includes an item pool update unit 37 and a question item creation unit 38 as maintenance means for the item pool 32.

  The item pool update unit 37 is a module that reclassifies the question items stored in the item pool 32 based on the answer data stored in the user database 39. In other words, new question items are grouped based on the predicted response tendency, but may be found to be unpredictable characteristics by actually being asked and answered by the subject. The item pool updating unit 37 analyzes appropriate characteristics of each question item based on the answer data accumulated in the user database 39, and deletes the question item included in the inappropriate group or moves it to the appropriate group. It has a function.

  The question item creation unit 38 acquires a new question item as text data, and stores it in the item pool 32 through the item pool update unit 37. For this new question item, a storage destination group is designated based on characteristics measured by other means. The new question items are actually presented, and the answer data is accumulated in the user database 39, so that the answer data can be analyzed and reclassified into an appropriate group by the item pool update unit 37. can do.

(Grouping in the item pool)
The question items in the item pool 32 described above are grouped according to the item reaction theory in this embodiment. That is, as shown in FIG. 1, the groups in the item pool 32 are configured according to the characteristics of psychological items such as “feeling of fatigue”, “feeling of irritation”, “feeling of tension”, “indifference”, etc. Each question item is created in a plurality so as to be suitable for examining these psychological items, and is grouped for each same characteristic.

  More specifically, in this embodiment, an item response theory is applied, a characteristic θ that does not depend on a group is set, and a characteristic of each item is described by a numerical value (parameter) that can be compared such as difficulty level and discriminating power. Specifically, in each group prepared for each scale, a plurality of question items satisfying a standard value with a certain degree of difficulty and discriminatory power are set in each group based on the item response theory.

The theoretical formula of the item response theory is as follows.

  Here, the above-mentioned difficulty level is a numerical value indicating how easily “applicable” is answered for a certain item. Taking stress response as an example, if the degree of difficulty is low even if the stress response is low, the answer is “applicable” (choose an option). On the other hand, if the degree of difficulty is high, the stress response is not very bad. It's harder to answer that.

  The discriminating power is a numerical value of how much a person in a certain state can be identified. Taking stress response as an example, if the discrimination power is too low, for example, even if the stress response is low, people who answered “applicable” and people who answered “not applicable” were mixed, and correct results were obtained. There will be no.

  As shown in FIG. 2, these parameters can be represented by, for example, a line graph in which the response rate and stress response for each option are plotted. Characteristics can be analyzed.

(Psychological examination method)
The psychological examination method of the present invention can be implemented by operating the psychological examination system having the above configuration. FIG. 3 is a flowchart showing the operation of the psychological examination system according to the present embodiment.

  First, the psychological examination system is activated when the examinee accesses the Web server 3. At this time, an authentication process for specifying the person to be inspected is performed. Then, the item extraction unit 34 randomly selects and extracts a predetermined number of question items from each of the groups 331 to 33n accumulated in the item pool 32 (S101).

  Next, the inspection information generation unit 35 embeds the extracted question item text data in a template of a predetermined format to create an inspection sheet (S102). Then, the data transmission / reception unit 31 displays the inspection sheet on the browser software of the user terminals 11 to 13 through the Internet 2 (S103).

  The examinee answers the question items on the Web, and returns the answered data to the Web server 3 side. On the Web server 3 side, the response data is acquired by the examination execution unit 36 and analyzed (S104). The analysis result is accumulated in the user database 39 together with the response data (S105).

(Item pool maintenance)
The answer data of the psychological examination executed in this way is totaled by the item pool updating unit 37, and the totaled result can be used for the maintenance of the item pool 32. FIG. 4 is a flowchart showing a maintenance procedure of the item pool 32.

  Here, it is assumed that psychological tests have already been performed many times and the test results are accumulated in the user database 39. First, the response data accumulated in the user database 39 is totaled by the item pool updating unit 37, and the general characteristic values of all the test subjects for the characteristics of each group and the response rate for each question item are obtained (S201). ).

  For each group characteristic, as shown in FIG. 2, the general characteristic value (for example, stress response) of all the test subjects is taken as the X axis, and the response rate for each option of the question items belonging to this group is shown. Plot as Y axis (S202).

  Next, the plot patterns of the question items belonging to each group are sequentially compared (S203), and it is determined whether or not they match the pattern tendency for each group (S204). If they match (“Y” in step S204), the next question item is compared (S205 and S209). If they do not match (“N” in step S204), the question item is deleted. Or move to an appropriate group (S208).

  When the comparison is completed for all question items (“Y” in step S205), the item pool 32 is updated (S206). The update of the item pool 32 reflects the deletion and movement of the question item in step S208, and adds a new question item when it is created (S209).

(Operational effects of this embodiment)
According to the psychological inspection system and method according to the present embodiment described above, a plurality of question items having the same characteristics are grouped and accumulated in the item pool 32, and a necessary number of question items are extracted from the group and inspected. In order to conduct inspections by creating a sheet, the number of questions can be reduced to shorten the inspection time and reduce the burden on the inspected person, and the inspection accuracy ensures reliability and validity. be able to.

  In the present embodiment, since the item response theory is applied to the grouping in the item pool 32, the general characteristic value is not affected by the characteristics of the examinee group like the average value and the standard deviation. Based on the above, the question items can be classified, and even if the number of question items is reduced, the inspection accuracy is not lowered.

  Furthermore, in this embodiment, since the item pool 32 is optimized by using the answer data stored in the user database 39, maintenance for improving inspection accuracy can be easily performed.
