Studying Psychosocial Barriers to Drug Treatment Among Chinese Methamphetamine Users Using A 3-Step Latent Class Analysis

Non-engagement in substance use treatment among women with an unmet need for treatment: A latent class analysis on multidimensional barriers

BACKGROUND

Women with substance use disorders experience multifaceted barriers in accessing substance use treatment. Little is known about how these barriers may aggregate. Using a person-centered approach, this study evaluates patterns of treatment barriers and the factors associated with experiencing distinct sets of barriers among women.

METHODS

Data were from the NSDUH (2015-2019). 461 adult women with an unmet need for substance use treatment in the last year reported on 14 treatment barriers. Latent class analysis examined classes of barriers; multinomial logistic regression assessed predictors of class membership.

RESULTS

Three classes were identified: just not ready to abstain (71.2%), logistical barriers and stigmatization (18.2%), and barriers across all dimensions (10.6%). Higher education (aOR:1.94, p = 0.03) and psychological distress (aOR:2.19, p = 0.02) predicted higher odds-and identifying as African American predicted lower odds (aOR:0.17, p = 0.02)-of belonging to the "Logistics and Stigma Barriers" class relative to the "Just Not Ready" class. Similarly, higher education (aOR: 2.57, p = 0.02) and having children (aOR:2.28, p = 0.03) predicted higher odds-and marriage predicted lower odds (aOR:0.22, p = 0.02)-of belonging to the "High and Diverse Barriers" class relative to the "Just Not Ready" class. Having children predicted higher odds (aOR: 2.93, p = .02), and marriage predicted lower odds (aOR:0.19, p = 0.02) of belonging to the "High and Diverse Barriers" class relative to the "Logistics and Stigma" class.

CONCLUSION

A lack of readiness to abstain, socioeconomic circumstances, and family obligations are main barriers to SUD treatment among women. Interventions incorporating motivational interviewing, family systems, and social networks are needed.

Barriers to accessing methamphetamine treatment: A systematic review and meta-analysis

BACKGROUND

Methamphetamine use is associated with a range of poor health, social and justice outcomes. In many parts of the world increased methamphetamine use has been identified as a major public health concern. Methamphetamine treatment programmes have been effective in reducing and ceasing use, however a range of barriers have prevented these programmes being widely adopted by methamphetamine users. This review examines the barriers to accessing meth/amphetamine treatment identified in the literature.

METHODS

Databases were systematically searched using relevant terms for peer-reviewed articles describing original research exploring the barriers to accessing treatment for meth/amphetamine use. Reviews and grey literature were excluded. Eleven studies conducted in 5 countries were included in data synthesis; this involved a systematic review of all 11 studies, and meta-analysis of the prevalence of barriers reported in 6 studies that published sufficient quantitative data.

RESULTS

Psychosocial/internal barriers to accessing methamphetamine treatment were most prevalent across studies (10/11 studies). Meta-analysis confirmed the four most commonly endorsed barriers to treatment access across studies all psychosocial barriers were embarrassment or stigma (60%, 95% CI: 54-67%); belief that treatment was unnecessary (59%, 95% CI:54-65%); preferring to withdraw alone without assistance (55%, 95% CI:45-65); and privacy concerns (51%, 95% CI:44-59%).

CONCLUSIONS

The primary barriers to accessing methamphetamine treatment are psychosocial/internal. Services and treatment models that address these barriers are urgently required. There is a growing need for methamphetamine-appropriate treatment services. Further research evaluating treatment engagement and effectiveness for methamphetamine and polysubstance use, including the development of effective pharmacotherapies is warranted.
