An acceptance-based, intersectional stigma coping intervention for people with HIV who inject drugs-a randomized clinical trial

Substance use stigma: A systematic review of measures and their psychometric properties

Background

Instruments to measure substance use stigma are emerging, however little is known regarding their psychometric properties. While research has evolved to view substance use stigma as a context sensitive international phenomenon that is embedded within cultures, validated self-report measures are lacking and comprehensive reviews of the existing measures are extremely limited. In this systematic review of substance use stigma and shame measures, we aim to contextualize results from existing research, lay the groundwork for future measurement development research, and provide a thorough resource for research scientists currently designing studies to measure substance use stigma.

Methods

We searched three databases using Boolean search terms for psychometric evaluations of measures of substance use stigma and shame and evaluated the quality/psychometric properties using an adaptation of the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) systematic review guidelines.

Results

We identified 18 measures of substance use stigma. Overall, most measures had minimal psychometric assessments and none of the measures met all domains of the COSMIN measure quality criteria. However, most studies reported satisfactory factor analyses and internal consistency scores.

Conclusions

Most measures of substance use stigma and shame had psychometric assessment across a limited range of criteria and no measures of structural substance use stigma were found. The most reported psychometric properties were structural validity and convergent validity. We suggest future researchers investigate test-retest reliability and cross-cultural validity for existing substance use stigma measures, as well as develop and evaluate novel measures assessing structural stigma of substance use.

Effectiveness of a mindfulness and acceptance-based intervention for improving the mental health of adolescents with HIV in Uganda: An open-label trial

Adolescents with HIV (AWH) face the double burden of dealing with challenges presented by their developmental phase while coping with stigma related to HIV, affecting their mental health. Poor mental health complicates adherence to daily treatment regimens, requiring innovative psychosocial support strategies for use with adolescents. We assessed the effectiveness of a mindfulness and acceptance-based intervention on the mental health of AWH in Uganda. One hundred and twenty-two AWH, mean age 17 ±1.59 (range 15 to 19 years), 57% female, receiving care at a public health facility in Kampala were enrolled in an open-label randomized trial (ClinicalTrials.gov: NCT05010317) with assessments at pre-and post-intervention. The mindfulness and acceptance-based intervention involved weekly 90-minute group sessions for four consecutive weeks facilitated by two experienced trainers. Sessions involved clarifying values, skillfully relating to thoughts, allowing and becoming aware of experiences non-judgmentally, and exploring life through trial and error. The control group received the current standard of care. Three mental health domains (depression, anxiety, and internalized stigma) were compared between the intervention and control groups. A linear mixed effects regression was used to analyze the effect of the intervention across the two time points. Results showed that the intervention was associated with a statistically significant reduction in symptoms of depression (β = -10.72, 95%CI: 6.25, -15.20; p < .0001), anxiety (β = -7.55, 95%CI: 2.66, -12.43; p = .0003) and stigma (β = -1.40, 95%CI: 0.66 to -2.15; p = .0004) over time. Results suggest that mindfulness and acceptance-based interventions have the potential to improve the mental health of AWH.

Stigma and other correlates of sharing injection equipment among people with HIV in St. Petersburg, Russia

Stigma that people with HIV who inject drugs experience negatively impacts HIV and substance use care, but stigma's association with sharing injection equipment is not known. This is a cross-sectional analysis of data from two studies of people with HIV reporting drug injection (N = 319) in St. Petersburg, Russia (September 2018-December 2020). We used logistic regression to examine associations between HIV stigma and substance use stigma scores (categorised into quartiles) and past 30-day equipment sharing, adjusting for demographic and clinical characteristics. Secondary analyses examined associations of arrest history and social support with sharing equipment. Almost half (48.6%) of participants reported sharing injection equipment. Among groups who did and did not share, mean HIV stigma (2.3 vs 2.2) and substance use stigma (32 vs 31) scores were similar. Adjusted analyses detected no significant associations between HIV stigma quartiles (global p-value = 0.85) or substance use stigma quartiles (global p-value = 0.51) and sharing equipment. Neither arrest history nor social support were significantly associated with sharing equipment. In this cohort, sharing injection equipment was common and did not vary based on stigma, arrest history, or social support. To reduce equipment sharing, investments in sterile injection equipment access in Russia should be prioritised over interventions to address stigma.
