A measure of subjective substance use disorder awareness - Substance Use Awareness and Insight Scale (SAS)

Quasi-randomized trial of solution-focused brief therapy intervention for readiness to change and alcohol and other drug use in a Brazilian community-based treatment center

OBJECTIVE

Strategies to increase readiness to change may enhance community-based substance use treatment outcomes. This study evaluated the effect of solution-focused brief therapy (SFBT) on readiness to change and substance use compared to treatment as usual (TAU) in a Brazilian community-based substance use treatment center.

METHODS

One hundred two adults (M = 36.79, SD = 10.29) were quasi-randomized into SFBT or TAU groups. Assessments were completed at baseline, post-test, and 1-month follow-up. The primary outcome was the changes in readiness to change at post-test and 1-month follow-up. The secondary outcome was the change in substance use at 1-month follow-up.

RESULTS

Through Quade non-parametric analysis of covariance (ANCOVA), both groups decreased tobacco, alcohol, and cocaine/crack use at 1-month follow-up, but SFBT had greater reductions in alcohol use (p = .05). ANCOVA analysis demonstrated no differences between groups on readiness to change at any time point. However, among participants who used multiple substances (n = 59), SFBT showed higher readiness to change at post-test (p = .05).

CONCLUSIONS

These findings strengthen the evidence that SFBT holds promise for positive community-based substance use treatment outcomes.

Associations between cannabis policies and state-level specialty cannabis use disorder treatment in the United States, 2004-2019

BACKGROUND

Cannabis use disorder (CUD) treatment prevalence decreased in the US between 2002 and 2019, yet structural mechanisms for this decrease are poorly understood. We tested associations between cannabis laws becoming effective and self-reported CUD treatment.

METHODS

Restricted-use 2004-2019 National Surveys on Drug Use and Health included people ages 12+ classified as needing CUD treatment (i.e., past-year DSM-5-proxy CUD or last/current specialty treatment for cannabis). Time-varying indicators of medical cannabis laws (MCL) with/without cannabis dispensary provisions differentiated state-years before/after laws using effective dates. Multi-level logistic regressions with random state intercepts estimated individual- and state-adjusted CUD treatment odds by MCLs and model-based changes in specialty CUD treatment state-level prevalence. Secondary analyses tested associations between CUD treatment and MCL or recreational cannabis laws (RCL).

RESULTS

Using a broad treatment need sample definition in 2004-2014, specialty CUD treatment prevalence decreased by 1.35 (95 % CI = -2.51, -0.18) points after MCL without dispensaries and by 2.15 points (95 % CI = -3.29, -1.00) after MCL with dispensaries provisions became effective, compared to before MCL. Among people with CUD in 2004-2014, specialty treatment decreased only in MCL states with dispensary provisions (aPD = -0.91, 95 % CI = -1.68, -0.13). MCL were not associated with CUD treatment use in 2015-2019. RCL were associated with lower CUD treatment among people classified as needing CUD treatment, but not among people with past-year CUD.

CONCLUSIONS

Policy-related reductions in specialty CUD treatment were concentrated in states with cannabis dispensary provisions in 2004-2014, but not 2015-2019, and partly driven by reductions among people without past-year CUD. Other mechanisms (e.g., CUD symptom identification, criminal-legal referrals) could contribute to decreasing treatment trends.

Association of sugar-sweetened beverage consumption and sleep quality with anxiety symptoms: a cross-sectional study of Tibetan college students at high altitude

Background

Research on the association between sugar-sweetened beverages (SSBs) consumption and sleep quality with anxiety symptoms has been highly emphasized. However, past studies have focused on college students in plains areas, while fewer research studies have been conducted on Tibetan college students at high altitudes. Whether this association changes due to ethnicity or altitude is unclear. The present study will contribute to the prevention and intervention of depressive symptoms among Tibetan college students at high altitude.

Methods

A self-assessment questionnaire was administered to 3,026 university students (1,491 boys students, 49.27%) on SSBs consumption, sleep quality and anxiety symptoms status in the Tibetan Plateau, a high-altitude region of China. Logistic regression analysis and ordered logistic regression analysis in generalized linear model were used to analyze the association between SSBs consumption and sleep quality with anxiety symptoms.

Results

The prevalence of anxiety symptoms among Tibetan college students at high altitude was 26.9%. SSBs consumption of ≤1 times/week, 2-5 times/week, and ≥ 6 times/week were 20.7, 28.1, and 45.7%, respectively, with statistically significant differences (χ2 value of 134.353, p < 0.001). Anxiety detection rates for Sleep quality of Good (PSQI ≤5), Moderate (PSQI 6-7), and Poor (PSQI >7) were 16.8, 19.8, and 32.0%, respectively, and the difference was also statistically significant (χ2 value was 73.761, p < 0.001). The ordered logistic regression analysis in the generalized linear model showed that, overall, the group of college students with SSBs ≤1 times/week and sleep quality of Good served as the reference group, and the group with SSBs ≥6 times/week and sleep quality of Poor (OR: 5.06, 95% CI: 3.75-6.83) had the highest risk of anxiety symptoms.

Conclusion

SSBs consumption and sleep quality were associated with anxiety symptoms, and there was an interaction effect. Effective control of SSBs consumption and improvement of sleep quality may be important factors in preventing and reducing the occurrence of anxiety symptoms.

Individual differences and predictors of general awareness in problem gambling

In Canada, up to 3% of individuals have or are at risk of gambling disorder. Among these individuals, a lack of awareness of their problem gambling is a common barrier to treatment and negatively affects treatment adherence. A secondary analysis was conducted on data from 1346 individuals (mean age = 43.4, SD = 14.4; 54.3 % male) with problem gambling who did and did not perceive having a problem with their gambling as assessed by the fifth item of the Problem Gambling Severity Index, "In the past twelve months, how often have you felt that you might have a problem with gambling?" Additionally, we investigated predictors of increased general awareness at 12-month follow-up. At baseline, individuals who perceived a problem with their gambling experienced more gambling-related harms (OR = 1.714), had greater total gambling losses (OR = 1.067), were more likely to have a family history of problem gambling (OR = 2.143), experienced a greater loss of control (OR = 1.313) and more often gambled alone than with others (OR = 0.879), accounting for 26.6 % of the variance in general awareness. Baseline problem awareness was positively associated with attempts to cut down or control gambling at follow-up (χ²=11.350,p<.001), but negatively associated with remission (χ²=18.392,p<.001). Increases in awareness were related to an increase in the number of gambling-related harms, gambling involvement, impaired control, and lower educational attainment, explaining 35.5% of the variance in increased general awareness. The results indicate that experiencing more gambling-related harms increases the salience and awareness of problem gambling, and that awareness is also associated with an individual's gambling context, their loss of control, and their level of gambling involvement. The findings highlight the importance of gambling harms as they pertain to general awareness and suggest that improving the recognition of gambling harms could be beneficial for the prevention and intervention of gambling disorder.
