[Development of the Brief Scales for Coping Profile (BSCP) for workers: basic information about its reliability and validity].

Coping profile of workers greatly affects the process where job stressors develop health problems, but most of the previously proposed questionnaires for the coping profile are too long to be applied to the program of occupational mental health. In the present study, the authors report the process of developing a new self-rating questionnaire for assessing workers' coping profile which includes only 18 questions. Based on the results of a preparatory study, the 18 questions which provide 6 scales about coping strategies were proposed as the Brief Scales for Coping Profile (BSCP). A self-administered questionnaire including BSCP, Brief Scales for Job Stress (BSJS), and a depression scale (CES-D) was applied to 394 workers in a company, and 328 (83%) responded. Their age was 40.1 +/- 10.0 yr (mean +/- SD), 78% were men, 75% were married, and most of them were white collar workers. Six factors extracted through factor analysis of BSCP closely agreed with the expected 6 scales and also with the results of previous studies. They were named "active solution", "seeking help for solution", "changing a point of view", "changing mood", "emotional expression involving others", and "avoidance and suppression". The Cronbach's reliability coefficients for the scales were from 0.66 to 0.75, showing sufficiently high internal consistency. None of them related to gender or age. Multiple regression analysis revealed that 38% of the variance of the depression score was explained by "workload", "problems in personal relationships", and "reward from work" scores in BSJS, and also with "active solution" and "avoidance and suppression" scores in BSCP. Interaction analysis revealed that the coping profile modifies the relationship between job stressors and depressive symptoms; the "active solution" score was inversely associated with the depression score, particularly for the workers with high "problems in personal relationships" scores and low "reward from work" scores, while "avoidance and suppression" scores were positively associated with the depression score particularly for the workers with high "problems in personal relationships" scores. These results support part of the reliability and validity of BSCP, and also support the feasibility of BSCP as a tool for self-management and health education concerning job stress in the field of occupational mental health. The test-retest reliability and concurrent validity of BSCP should be confirmed in a future study. It also should be confirmed in future whether the coping profile relates with gender, age, job type, or other outcome of job stress in other populations.
