Background: Substance abuse is a critical problem in most countries, especially in developing ones. Early detection is the pre-requisite of early control, for which reliable and valid tools are required. In the present study, we aimed at measuring the psychometric properties of the 10-item Drug Abuse Screening Test (DAST-10) in Iranian individuals.
Methods: After translation and back-translation of the questionnaire, 244 adults were recruited from Tehran Megacity, Iran, and completed the questionnaires. Participants were recruited by a multistage randomized cluster sampling method. Reliability was determined by Cronbach's alpha. Also, construct validity was evaluated using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA).
Findings: The internal consistency using Cronbach's alpha coefficients for the total score of the Persian version of DAST-10 was 0.93. EFA evoked only one factor for DAST-10. The CFA for 1-factor models for DAST-10 indicated an acceptable fit for the proposed models.
Conclusion: The results prove desirable reliability and validity of the Persian version of the DAST which can be utilized as a screening instrument for drug abuse among Iranian adults.

This integrative review systematized the factors that influence access to mental health services for the Homeless Population (HP) in harmful use of alcohol and other drugs in the Psychosocial Care Network (RAPS) in Brazil by categorizing the factors into access "barriers" and "facilitators". We selected 13 corresponding articles and subsequently assessed their methodological quality. We identified 19 access barriers and 22 access facilitators, observing a convergence and complementarity of the factors identified, with no disagreements between authors.

Fatal overdoses among people with HIV experiencing nonfatal overdoses in British Columbia, Canada.

The breadth of the overdose crisis is underestimated because of a lack of quantifying nonfatal overdoses. We estimate the proportion of nonfatal overdoses among all people with HIV (PWH) in British Columbia, Canada, and the prevalence of fatal overdoses among people who had a nonfatal overdose, stratified by sex. A small proportion of PWH who experienced a nonfatal overdose subsequently died of a fatal overdose, signaling opportunities for crucial interventions and treatment to prevent overdose death.
