The Effect of Divorce on Suicide in Japan: A Time Series Analysis, 1950-1980.

The article explores the relationship with data from a nation with a substantially different social context, Japan. American research on suicide has been based largely on American samples. Little is known about whether the results of this work, such as the link between divorce and suicide, will be replicated for nations with substantially different institutional and cultural structures. The present paper tests the marital integration theory of suicide with data from Japan. Briefly, the marital integration theory holds that as bonds to marriage weaken, suicide risk increases. Further, the kinship system in Japan is apparently more integrated than it is in the United States. For example, in Japan 37.3% of the elderly lived in three-generation households compared to only 0.5% of the elderly in the United States. Durkheim's theory of social integration and suicide emphasizes the subordination of the individual to group life as a prophylactic against suicide. Individualism in family life was emerging as the pattern for the future at the time of Durkheim's study. It is anticipated that a rising divorce rate should affect suicide risk for several groups: divorced persons; separated persons who are contemplating divorce; married persons with severe marital problems; and the children in such families.
