Abstract

Background: Interventions to prevent depression in older adults have mainly focused on young-old ambulatory adults, not on the old-old with disabilities who receive supportive services in their homes. Objective: The Depression Agency-Based Collaborative (Dep-ABC)is a single-blind pilot randomized controlled trial assessing the effect of an intervention-development strategy using problem-solving therapy (PST)on the risk of common mental health disorders in this vulnerable population. Methods: The intervention involved six to eight sessions of PST over 12 weeks. Participants were followed up to 12 months postintervention. Results: Dep-ABC randomized 104 participants—68.4% of eligible and 17.5% of all older adults screened. The proportion of participants with incident major depressive disorder or generalized anxiety disorder was 11.4% in PST and 14.3% in the enhanced usual care control arm. A test of the interaction between time and intervention for anxiety symptoms favored the PST arm (p = 0.04). Conclusion: PST did not lower the risk of incident common mental illness but did lower anxiety symptom burden. Apart from low power, the effects of PST may have been blunted by referral for medical and aging services in the enhanced usual care group.
