Expressed emotion (EE) is a robust predictor of outcome in bipolar disorder. Despite decades of research, interventions to reduce EE levels have had only modest effects. This study used an expanded model of EE to develop an intervention. Research has demonstrated a strong link between attributions and EE in families of patients with psychiatric disorders. There is also substantial research to suggest that anger can drive blaming attributions. Combining these ideas, this study built on previous psychoeducation interventions through the addition of an acceptance component designed to decrease anger and blaming attributions among family members of those with bipolar disorder. Twenty-eight family members attended a 1-day or 2-evening multifamily group workshop and completed a follow-up assessment 1 week later. At follow-up, participants demonstrated more knowledge about bipolar disorder. Anger, blaming attributions, and number of criticisms remained unchanged. Results of this study are consistent with others in that it is difficult to change EE. Implications for future clinical research in this area are addressed. (Contains 4 tables.)
