ABSTRACT
BACKGROUND: Two, randomized controlled trials found harm-reduction treatment for AUD (HaRT-A) improves alcohol outcomes for adults experiencing homelessness. HaRT-A, which neither requires nor precludes abstinence, entails tracking alcohol-related harm, harm-reduction goals, and safer-use strategies. This secondary dual study qualitatively describes this last component, safer-use strategies, and their quantitative association with treatment outcomes. METHODS: Participants were people who experienced homelessness and AUD and were enrolled in the active HaRT-A treatment arms in 2 randomized control trials (Trial 1 N = 86; Trial 2 N = 208). Trial 1was a 2-arm study with randomization to HaRT-A or services as usual. Trial 2 was a 4-arm study combining HaRT-A and extended release naltrexone. In HaRT-A sessions, participants received a list of 3 categories of safer-use strategies (i.e., buffering alcohol's effects on the body, changing the manner of drinking to be safer and healthier, and reducing alcohol use). Mixed methods were used to qualitatively describe safer-use strategies implemented and quantitatively test their association with alcohol outcomes (i.e., peak quantity, frequency, alcohol-related harm). RESULTS: In Trial 1, but not Trial 2, participants committed to more safer-use strategies across time, which was associated with reductions in alcohol frequency over the past 30 days. In both trials, participants committing to reducing alcohol consumption drank on a quarter fewer days overall, and in Trial 2, experienced 15 % less alcohol-related harm. In Trial 1, participants who committed to changing the manner of drinking were heavier drinkers overall, and although they showed significant reductions in alcohol-related harm, their reduction rate was slower than for participants who selected other strategies. In Trial 2, strategies to buffer alcohol's effects were associated with a monthly 14 % decrease of alcohol-related harm. CONCLUSION: This study replicated prior findings that people experiencing homelessness and AUD regularly adopt strategies to reduce alcohol-related harm. The implementation of safer-use strategies was favorably associated with alcohol outcomes, but specific associations differed by trial and outcome. Discussion of safer-use strategies appears helpful; however, further research is needed to firmly establish how this HaRT-A component works.
ABSTRACT
Prior research suggests that culturally aligned, accessible and lower-barrier interventions are well-placed to align with the needs of American Indian and Alaska Native (AI/AN) people with alcohol use disorder (AUD). Taking into account community members' suggestions and the need for physical distancing during the COVID-19 pandemic, our team developed a protocol for virtual Harm Reduction Talking Circles (HaRTC) to incorporate these points. The aims of this 8-week, single-arm pilot were to initially document feasibility, acceptability, and outcomes associated with attendance at virtual HaRTC, which integrates the accessibility of virtual connection, a lower-barrier harm-reduction approach, and a culturally aligned intervention. Participants (N = 51) were AI/AN people with AUD (current or in remission) across 41 Tribal affiliations and 25 US states. After a baseline interview, participants were invited to attend 8, weekly virtual HaRTC sessions. At the baseline, midpoint and post-test assessments, we collected data on virtual HaRTC acceptability, cultural connectedness, quality of life, and alcohol outcomes. Of the 123 people approached, 63% were interested in and consented to participation. Participants attended an average of 2.1 (SD = 2.02) virtual HaRTC sessions, with 64% of participants attending at least one. On a scale from 1 to 10, participants rated the virtual HaRTC as highly acceptable (M = 9.3, SD = 1.9), effective (M = 8.4, SD = 2.9), culturally aligned (M = 9.2, SD = 1.5), helpful (M = 8.8, SD = 1.9), and conducted in a good way (M = 9.8, SD = 0.5). Although the single-arm study design precludes causal inferences, participants evinced statistically significant decreases in days of alcohol use and alcohol-related harm over the three timepoints. Additionally, both sense of spirituality, which is a factor of cultural connectedness, and health-related quality of life increased over time as a function of the number of HaRTC sessions attended. Virtual HaRTC shows initial feasibility and acceptability as a culturally aligned intervention for AI/AN people with AUD. Future randomized controlled trials will provide a test of the efficacy of this approach.
