Brief group psychoeducation for caregivers of individuals with bipolar disorder: A randomized controlled trial.

BACKGROUND

Bipolar disorder is associated with significant impairment in personal and social functioning for the individual and their caregivers. Psychoeducation for caregivers is beneficial, but interventions have typically required a significant time commitment and have not assessed changes in self-efficacy. This study evaluated the effectiveness of a brief, two-session psychoeducational intervention for caregivers. It was hypothesized that the intervention would reduce caregiver burden and distress, and increase bipolar disorder knowledge and bipolar disorder self-efficacy.

METHODS

Participants (N=32) were randomized to immediate or waitlist control conditions. The intervention involved two, 150-minute group sessions spaced one-week apart. At pre-, post-, and one-month follow-up participants completed the Depression, Anxiety, Stress Scale (DASS-21), Burden Assessment Scale, Knowledge of Bipolar Disorder Scale, and a Bipolar Disorder Self-efficacy Scale.

RESULTS

Compared to the waitlist control group, the immediate treatment group demonstrated large and significant reductions in caregiver burden, and increases in bipolar disorder knowledge and bipolar disorder self-efficacy. These improvements maintained or increased to follow-up. No significant change was observed on the DASS-21.

LIMITATIONS: Reliance on self-report and the sample comprised mostly of parents and partners, so it unclear if results generalize to other carer groups.

CONCLUSIONS

Large and enduring improvements in carer burden, knowledge, and bipolar disorder self-efficacy can be achieved from a very brief, two-session intervention.
