Abstract
The authors conducted a nationwide psychiatric hospital survey in Japan to investigate the characteristics of solvent abusers among patients who visited or were admitted to psychiatric hospitals for solvent dependence or mental disorders resulting from solvent abuse. The findings from this survey confirm that the relationship between the parents and the cohesiveness of the family have a strong influence on juvenile solvent abuse. The survey data show several characteristic features in the attitudes of patients' parents toward their children. The data also show an association between the age when patients were separated from their parents and the patients' first solvent abuse.
