Randomized trial comparing caregiver-only family-focused treatment to standard health education on the 6-month outcome of bipolar disorder

Abstract

Objectives: Caregivers of people with bipolar disorder often have depression and health problems. This study aimed to evaluate the sustained effects of a 12-15 week psychoeducational intervention on the health and mental health of caregivers of persons with bipolar disorder. We also evaluated the effects of the intervention on patients' mood symptoms over 6 months post-treatment.

Methods: Caregivers of 46 persons with bipolar disorder were randomized to 12-15 weeks of a caregiver-only adaptation of family-focused treatment (FFT), in which caregivers were instructed on self-care strategies and ways to assist the patient in managing the illness, or to 8-12 sessions of standard health education. Independent evaluators assessed caregivers' depression and physical health and patients' mood symptoms before treatment, immediately after the treatment, and at 6 months post-treatment.

Results: Randomization to FFT was associated with greater decreases in depression for both caregivers and patients over a 6-month follow-up period post-treatment. Reductions in patients' depression scores over 6 months post-treatment were mediated by reductions in caregivers' depression scores (z = -2.74, P < .01).

Conclusions: Interventions that are effective in reducing mood symptoms and improving health behavior in caregivers may have important health and mental health benefits for patients with bipolar disorder. Specifically, a treatment focused on caregiver education about bipolar disorder and the need for the caregiver to attend to his/her own health and mental health can benefit patients, even without their direct participation.
