| Research Abstract |
The purposes of this study were (1) development of a convenient mental health evaluation (IRT-CAT)system for students and adults (workers) and (2) verification of the availability of that mental health evaluation system in school and occupational settings. As the first part of the study, response data of adult workers on the mental health scales, CES-D, K6 and STAI-YZ, were subjected to an analysis of polytomous item response theory model to identify the threshold and discrimination parameters of each item on a latent trait continuum for mental health. Responses of junior and senior high school students on SRQ-20, PSI junior high school student stress reaction scale and Birleson's depression self-rating scale for children (DSRS-C) were also subjected to the same IRT analysis. The initial version of IRT-CAT system was developed using these parameters. As the second, a field trial of that IRT-CAT system was conducted in two occupational settings. As discussed with occupational physicians and health care staff, the trial system consisted not only of mental health assessment but of measurements for factors affecting mental health of workers, such as stressors at workplace, social support, and organizational commitment. Thus, the system covered overall life and health conditions of workers. After the revision based on these trials, the final version of IRT-CAT system for mental health assessment of workers was constructed.
