Objective: To assess the family-of-origin characteristics of patients with
bipolar disorder relative to those of control subjects.
Method: Fifty-six euthymic patients meeting research diagnostic criteria fo
r bipolar disorder and 21 control subjects completed the Family Environment
Scale (FES) for the family they grew up with.
Results: The 2 groups showed strikingly similar profiles on 10 indices of f
amily functioning or structure.
Conclusions: The results do not support the hypothesis that specific family
attributes contribute to the development of bipolar disorder.
