The impact of primary care behavioral health services on patient behaviors: A randomized controlled trial.

Abstract

Greater understanding of the impact of low intensity psychosocial interventions delivered by behavioral health clinicians (BHCs) working in an integrated care program (ICP) may promote better depression care. In a randomized controlled trial, 153 participants identified as depressed by their primary care provider (PCP) were assigned to ICP or usual care (UC, management by PCP, including specialty referral). In the ICP condition, BHCs worked collaboratively with PCPs and liaison psychiatrists. ICP participants with lower and higher severity symptoms reported significantly greater use of coping strategies than UC participants at the 1-month follow up (lower: p = .002; higher: p = .016). ICP participants with lower severity continued to report significantly greater use of coping strategies than UC participants at the 4-month (p = .024), and 7-month (p = .012) follow ups. ICP participants were more likely to be following relapse preventions plans at the 4-month follow up (lower: 89.5% vs. 50%, p = .0.000; higher 74.1% vs. 33%, p = .0001). ICP participants also reported use of antidepressant medications on more days than UC participants at the 4-month follow up (lower: 21.27 vs. 14.49 days, p = .049; higher: 24.61 vs. 17.08 days, p = .035). Patient retention in the ICP was high, and ICP participants were significantly more satisfied with depression care than UC participants at follow-up assessments. Delivery of low intensity psychosocial interventions by BHCs was associated with improvements to behavior charge targets. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
