| Outline of Final Research Achievements |
The authors have been involved with research using ecological momentary assessment technique, and also developed an electronic food diary application, which was validated. The aim of the present study was to develop a self-management tool for physical and psychological aspects using smartphones. To develop computerized adaptive testing (CAT) system, we developed item pools for psychological states such as depressive mood. The subjects were 313 healthy people, 101 patients with depression, 69 patients with anxiety disorders, and 100 patients with metabolic syndrome. Using item response theory, item pools for psychological states were developed, and their reliability and validity were confirmed. Then, the CAT system was implemented into smartphones, and visualization function of symptoms and behavior was developed to accomplish a self-care tool.
