"The Checklist for Evaluation of Mental Health Activities at the Workplace" was developed for workplace staff evaluating mental health activities in their own workplace. The validity and reliability of the checklist were examined and criteria for evaluation were developed for workplace/organization/companies with 50 or more employees in Japan. The checklist initially included 33 items covering seven major domains of occupational mental health, with a four-point response option, based on the Japanese Guideline for Worker Mental Health in the Workplace and a relevant literature review. A questionnaire was send to 60 members of the Occupational Mental Health Committee (OMHC) of the Japan Society for Occupational Health to ask their opinions on the checklist and on the minimum requirement for each item on the checklist; 30 (50%) responded. A random sample of 1,335 workplaces from a contractor list of workplaces for worker compensation insurance and a questionnaire was send to the personnel department to fill in the checklist; 412 (31.5%) responded and data from 335 of them with 50 or more employees were analyzed. Some OMHC members felt that one of the items (concerning the Total Health Promotion program) should be dropped; thus the checklist was revised to include 32 items, still covering the seven domains. Based on the workplace survey data, most domain scales showed internal consistency reliability at an acceptable level; explanatory factor analysis yielded a four-factor structure that was well concordant with the hypnotized seven-domain structure. Three levels of adequacy of mental health activities were set for each domain scale: "red" (inadequate), "yellow" (minimal), and "green" (adequate). One third of occupational health professionals from 49 workplaces rated the evaluation result based on the checklist as concordant with their view; 95% of them said the checklist would be useful in promoting occupational mental health activities. The study indicated that the checklist had reliability (based on internal consistency reliability) and content- and construct-validity (based on expert opinions, a factor-structure concordant with empirical data, and evaluation by workplace staff). The checklist seems useful in promoting occupational mental health activities.
