Relationship of temperament and perceptions of nonshared environment in bulimia nervosa

Objective: Examine the relationship between temperament variables and perce ptions of nonshared environment as they relate to bulimia nervosa. Method: Fifty-seven adult women completed the Tridimensional Personality Questionna ire and the Sibling Inventory of Differential Experience. These measures pr ovided assessments of frequently studied temperament traits as well as nons hared environmental factors believed to be associated with psychopathology and temperament. Results: Bulimic subjects showed higher levels of harm avo idance than did control subjects. Also, bulimic subjects perceived their fa thers as less affectionate and more controlling than control subjects. Amon g bulimics, high levels of harm avoidance were associated with high levels of maternal affection and low levels of maternal control. Similarly, among bulimics, high levels of novelty seeking were more likely to be associated with decreased paternal control than was true for control subjects. Discuss ion: These findings highlight the possible relationship between particular temperamental variables and associated family responses in bulimia nervosa. (C) 2000 by John Wiley & Sons, Inc.
