Changes in Attitudes toward People with Substance Use Disorder: A Comparative Study of the General Population in Mexico

Promoting substance use stigma resistance through an automated text message intervention (project RESTART): Outcomes of a pilot feasibility trial

BACKGROUND

Stigma in people who use drugs predicts treatment engagement, psychosocial health, and overdose, yet there are few evidence-based interventions to support people who use drugs in managing and coping with substance-related stigma and even fewer for people in active use. mHealth is one option to engage this hard-to-reach population.

METHODS

Premised on the theory of stigma resistance, this mixed-methods study explored the feasibility, acceptability, and preliminary effectiveness of Project RESTART, a four-week, automated text message intervention for rural-dwelling people who use drugs (n = 30) using a one-group pre-post design. The study recruited participants from syringe service programs and by word-of-mouth.

RESULTS

Key outcomes included high retention (90 %), message engagement (median responses: 4, interquartile range: 1-17), acceptability (mean item score: 3.55, standard deviation: 0.34, range: 1-4), and preliminary effectiveness in the main outcomes (Cohen's d: stigma resistance (0.56), self-stigma (0.50)). Results were corroborated in sub-sample follow-up interviews (n = 13).

CONCLUSION

These promising findings suggest text messaging is a feasible and acceptable modality for delivering stigma education and coping resources. Effectiveness should be established in a full-scale randomized controlled trial. This trial was registered at ClinicalTrials.gov on February 20, 2024 (NCT06281548).

Perceptions of substance use disorder in rural areas: how the brain disease model impacts public stigma

BACKGROUND

Rural communities are disproportionately affected by substance use disorder (SUD) and public stigma impedes access to and utilization of treatment and support services.

METHODS

This study compares data from a 2020 study conducted in rural Ohio (N = 173) with results from a recent study conducted in South Dakota (N = 41) on publicly-held stigmatizing views of SUD. South Dakota participants were recruited at several public events across the state via convenience sampling between August 2022-February 2023 to complete a survey. Data from responses to 19 stigma-related questions were merged with the associated data from the 2020 Ohio study and a comparative analysis was performed using Fisher's exact and Chi square tests.

RESULTS

The data shows that respondents in South Dakota, when compared to respondents in Ohio, are more likely to believe addiction is an illness (SD = 86.5%, OH = 48.5%, p < 0.001). The belief in SUD as an illness aligns with reduced stigmatizing beliefs, as indicated by respondents in SD showing lower stigmatizing ideologies and higher support for naloxone and harm reduction services, when compared to Ohio respondents. In both studies, the belief that SUD is an illness was associated with a reduction in other stigmatizing beliefs.

CONCLUSIONS

These results can be used to inform more focused anti-stigma efforts. As more people adopt fewer stigmatizing views on SUD in rural areas, more people with SUD may be supported to seek treatment and recovery services.

Initial evidence of reliability and validity of an implicit association test assessing attitudes toward individuals who use substances

Background: Substance use disorders (SUDs) are stigmatized conditions, with individual biases driving poor health outcomes. There are surprisingly few validated measures of bias or stigma toward individuals who use substances. Bias can be classified as explicit (self-report) or implicit (behaviorally based).Objectives: The goal of the present study was to establish preliminary indices of reliability and validity of an implicit association test (IAT) designed to measure implicit bias toward individuals who use substances.Methods: A large United States-based, crowd-sourced sample (n = 394, 51.5% male, 45.4% female, 2.5% nonbinary) completed the IAT and a small battery of survey instruments that assessed social distance to mental illness (including heroin use), attitude toward and perceived controllability of injection drug use, perception of public stigma, and social desirability.Results: Nearly all (92%; n = 363) scores on the IAT indicated greater negative than positive attitudes toward those who use substances. Spearman-Brown corrected split-half reliability on the IAT scores was excellent, r = .953. Controlling for social desirability, IAT scores positively correlated with all included measures pertaining to substance use as well as social distance for heroin and schizophrenia (but not diabetes). A principal component analysis resulted in two interpretable components representing disapproval (perceived controllability and negative attitudes) and perceived stigma (social stigma and social distance). Scores on the IAT positively correlated to scores on both components, again, controlling for social desirability.Conclusion: These results provide compelling preliminary evidence of validity of an IAT designed to measure bias toward individuals who use substances.

Community-level determinants of stakeholder perceptions of community stigma toward people with opioid use disorders, harm reduction services and treatment in the HEALing Communities Study

BACKGROUND

Community stigma toward people with opioid use disorder (OUD) can impede access to harm reduction services and treatment with medications for opioid use disorder (MOUD). Such community OUD stigma is partially rooted in community-level social and economic conditions, yet there remains a paucity of large-scale quantitative data examining community-level factors associated with OUD stigma. We examined whether rurality, social inequity, and racialized segregation across communities from four states in the HEALing Communities Study (HCS) were associated with 1) greater perceived community stigma toward people treated for OUD, 2) greater perceived intervention stigma toward MOUD, and 3) greater perceived intervention stigma toward naloxone by community stakeholders in the HCS.

METHODS

From November 2019-January 2020, a cross-sectional survey about community OUD stigma was administered to 801 members of opioid overdose prevention coalitions across 66 communities in four states prior to the start of HCS intervention activities. Bivariate analyses assessed pairwise associations between community rural/urban status and each of the three stigma variables, using linear mixed effect modeling to account for response clustering within communities, state, and respondent sociodemographic characteristics. We conducted similar bivariate analyses to assess pairwise associations between racialized segregation and social inequity.

RESULTS

On average, the perceived community OUD stigma scale score of stakeholders from rural communities was 4% higher (β=1.57, SE=0.7, p≤0.05), stigma toward MOUD was 6% higher (β=0.28, SE=0.1, p≤0.05), and stigma toward naloxone was 10% higher (β=0.46, SE=0.1, p≤0.01) than among stakeholders from urban communities. No significant differences in the three stigma variables were found among communities based on racialized segregation or social inequity.

CONCLUSION

Perceived community stigma toward people treated for OUD, MOUD, and naloxone was higher among stakeholders in rural communities than in urban communities. Findings suggest that interventions and policies to reduce community-level stigma, particularly in rural areas, are warranted.

Equine-assisted therapy effectiveness in improving emotion regulation, self-efficacy, and perceived self-esteem of patients suffering from substance use disorders

Substance Use Disorders (SUD) is a universal overwhelming public health problem and is associated with other psychological and mental health ailments such as emotion regulation, perceived self-esteem, and self-efficacy problems. Complementary and alternative medicine may be beneficial. The aim of this study was to assess the effectiveness of equine-assisted therapy in improving emotion regulation, self-efficacy, and perceived self-esteem among patients suffering from substance use disorders. It was carried out using a randomized controlled trial design at Behman hospital, Cairo, Egypt. It included 100 patients suffering from SUD attending the setting, equally randomized into an intervention group to receive the equine assisted therapy and a control group to receive the regular care. Data were collected using a self-administered questionnaire with standardized tools for assessment of emotion regulation, General Self-Efficacy (GSE), and perceived self-esteem. The intervention group received weekly equine-assisted therapy sessions over 6 weeks in addition to their standard regular therapy. Patients in both groups had similar demographic and SUD characteristics, as well as baseline scores of reappraisals, suppression, GSE and perceived self-esteem. At post-intervention, the intervention group had significant improvements in all these scores in comparison with the control group, as well as their baseline. The multivariate analysis identified the study intervention as a significant positive predictor of the reappraisal and GSE scores, and a negative predictor of the suppression and perceived self-esteem negative score. In conclusion, equine assisted-therapy as a complementary treatment in patients suffering from SUD is effective in improving their emotion regulation, self-efficacy, and perceived self-esteem. A wider use of this approach is recommended in SUD patients along with provision of needed facilities and resources, and training nurses in its administration. Further research is proposed to assess its long-term effectiveness. The clinical trial was registered in the "Clinical Trials.gov Protocol Registration and Results System (PRS);" registration number is (05632185/2022) and the full date of first registration is 10/11/2022.
