Workaholism among employees in Japanese corporations: An examination based on the Japanese version of the workaholism scales

To examine the validity and reliability of the Japanese version of the Workaholism Scales developed originally by J. T. Spence and A. S. Robbins (1992), a questionnaire survey of workers in Japanese industrial organizations was conducted. The Japanese questionnaire was developed by back-translation, Added to the original questionnaire were scales for work overload - quantity, work overload - quality, role ambiguity and role conflict. A total of 1,072 workers (962 men, 110 women) returned usable data (response rate = 87.5%). The factor structure and reliability of the workaholism instrument for Japanese male subjects look almost identical to those obtained by the original study in America except that the work involvement dimension was not reproduced as an independent factor, but overlapped with the drive dimension for the Japanese sample. There was 3 significant impact of workaholism on job stress and health complaints among Japanese male employees.
