Feasibility study of a peer-facilitated low intensity cognitive-behavioral intervention for mild to moderate depression and anxiety in older adults

摘要

Objectives: The majority of older adults experiencing depression and/or anxiety do not receive adequate treatment due to limited access to evidence-based practices. Low intensity cognitive-behavioral intervention has been established as an evidence-based practice with the potential to increase the reach to older adults. The purpose of the current study is to evaluate the feasibility, acceptability, and potential efficacy of a low intensity, peer-supported, cognitive-behavioral intervention for mild to moderate depression and/or anxiety delivered by a local intergovernmental agency serving older adults.Method: Sixty-two older adults (81% female) between 55 and 96years of age were randomly assigned to either a peer-facilitated cognitive-behavioral bibliotherapy condition (n = 31) or a wait-list control condition (n = 31).Results: The 10-week feasibility trial data indicated that (1) a majority of the participants were highly engaged in the intervention with an average number of 7.3 peer sessions attended and 2.1 workbooks completed, (2) the participants were quite satisfied with the peer mentoring sessions and moderately satisfied with the workbooks, and (3) there were clinically meaningful reductions in depressive symptoms for those assigned to the treatment condition compared to those that were wait-listed (d = .43), though the effect was non-significant (p = .099) due to the small sample size. The evidence for the impact on reducing anxiety symptoms was more equivocal with a non-significant, small effect size favoring the treatment condition.Conclusion: The pilot study provided preliminary evidence for the feasibility, acceptability, and potential efficacy of the peer-facilitated low intensity cognitive-behavioral therapy intervention approach.
