Pilot Trial of a Transdiagnostic Cognitive Behavioral Therapy (CBT)-Based Group Intervention to Reduce Psychological Distress, Facilitate Positive Behavior Change, and Mitigate Inflammation in Older People with HIV.

Abstract

More than half of adults with HIV in the United States are aged 50 or older. Older people with HIV (OPWH) are disproportionately affected by age-related health disparities and non-communicable diseases associated with inflammation. The current pilot randomized controlled trial (RCT) evaluated the feasibility and acceptability, while exploring signals of effects of a transdiagnostic cognitive behavioral therapy (CBT) modular group teaching skills to cope with distress, make positive health behavior changes, and ultimately reduce inflammation. Participants were 31 virally undetectable, and psychiatrically stable OPWH (age [Formula: see text]50 years). Participants were randomized 1:1 to enhanced usual care or CBT for HIV and Symptom Management (CHAMP). CHAMP consists of 12-weekly virtual group sessions led by two interventionists. Self-report questionnaires and intravenous blood draws were collected at baseline and follow-up. Intervention participants completed an exit interview. Of those screened eligible, 96.8% (30/31) were randomized (n = 15 per group), 86.7% (13/15) completed the intervention, and 87% (26/30) completed the follow-up. On acceptability questionnaires scaled 0-3, participants reported high satisfaction and the intervention to be of high quality (M(SD)=3.00(0.0) for both). They also indicated their needs were met (2.67(0.50)) and coping improved (2.60(0.52)). Intervention participants showed a mean decrease in anxiety (-1.07(6.08)) and depressive (-1.71(5.37)) symptoms on clinical screeners, and mean increase in quality of life (2.86(3.59)). CHAMP is both feasible and acceptable for OPWH. Exploratory analyses indicate favorable outcomes for improving psychological distress and health-related quality of life.
