Harm Reduction Behavioral Activation Teletherapy for People Who Inject Drugs: Development, Feasibility, and Acceptability.

People who inject drugs (PWID) experience severe substance-related harms and yet have low rates of engagement in substance use disorder treatment. Low-barrier and telepsychology interventions represent promising strategies for engaging PWID in treatment, but few studies have tested the feasibility of these approaches among non-treatment-seeking PWID. A behavioral activation (BA) treatment for substance use was adapted through a harm reduction lens to assist PWID in working toward healthy, meaningful lives and achieving their goals. This study aims to: (a) describe the development and harm reduction-focused adaptation of the BA intervention, and (b) examine the feasibility and acceptability of administering a telepsychology BA treatment for substance use among non-treatment-seeking PWID. We recruited N = 23 PWID (65.2% White; 52.2% women; mean age 35.4±7.8 years) from syringe services programs into an open trial and n = 19 received up to eight sessions of BA over 4 weeks. Qualitative treatment feedback interviews occurred at posttreatment. Among those who attended ≥1 session of treatment, 84% attended a second assessment, and 58% attended ≥7 intervention sessions. Feasibility challenges were primarily related to participant vulnerabilities (e.g., hospitalization, incarceration, loss of access to technology). Participants indicated high acceptance of the intervention and its telepsychology format. In conclusion, while PWID face significant barriers to engaging in treatment, some also demonstrate a desire, willingness, and capacity for psychological intervention. Remote interventions may help increase feasibility of treatment participation. Future studies should examine longer harm reduction-focused treatments for PWID that balance barriers to initial engagement with the need to reinforce treatment gains and improve long-term outcomes.
