Expressed emotion attitudes and individual psychopathology among the relatives of bipolar patients.

This study investigated the relationships between expressed emotion (EE) and individual psychopathology among 82 biological and non-biological relatives of 66 patients with bipolar I disorder. Relatives' psychopathology was assessed via the Structured Clinical Interview for DSM-III-R, Patient Version (SCID-P) and the General Behavior Inventory (GBI), a self-report measure of lifetime subsyndromal mood disturbances. We hypothesized that relatives who held high-EE critical, hostile, and/or overinvolved attitudes toward their bipolar family member, as measured via the Camberwell Family Interview, would be more likely to have DSM-III-R Axis I diagnoses on the SCID, as well as more mood and temperamental disturbances on the GBI, than those who held low-EE attitudes. The findings did not support a significant relationship between overall EE status and psychopathology in family members. However, relatives without significant Axis I pathology scored significantly higher than those with Axis I pathology on one measure of EE, emotional overinvolvement. The findings are discussed with reference to explanations for the genesis of high-EE attitudes.
