The present paper reviewed the findings about the psychological consequences of Tanshinfunin on transferees and their familles, and made suggestions for the future. Tanshinfunin is the relocation of company members, with their family left behind. Such study began in around 1980. Five approaches were found out in the studies: the family, the developmental, the industrial, and the social psychological approaches, and finally the cross-cultural approache. The family psychological approach had the lead based on the family stress theory studying the effects of family separation or father/ husband absence on family members' mental stress and family stress, and the moderators of the relationship between family separation and stresses. This paper also reviewed overseas studies on job-related family separation of air force families etc., though such cases might be somewhat different from the Tanshinfunin in Japan. The most important findings were that there were less findings compared with more data, and studies with clear-cut hypothesis must be emphasized in the future.
