psychometrics properties of the persian version of distress tolerance scale for alcoholics and drug addicts

Background: alcohol and drugs have been widely consumed over the past centuries. distress tolerance, defined as the capacity to maintain goal-directed activities while experiencing psychological distress, is linked to unfavorable outcomes in substance use treatment, including dropout from drug and alcohol programs and relapse. objectives: this study aims to evaluate the psychometric features of the persian version of the distress tolerance scale (dts) in iranian drug addicts and alcoholics. methods: this study was performed to assess the psychometric features of the dts by using a convenient sampling method on 470 drug and alcohol users among iranian sample populations in prisons, addiction rehabilitation camps, hospitals, addiction treatment clinics that dispense methadone, and na centers in the year 2021. the methodology of this study is divided into two stages. in the first stage, the dts was translated into persian. the second stage was performed to check the validity and reliability. statistical analysis of this study was conducted using spss, amos25, and jasp 0.9.0.1 software. results: the outcome of this study revealed that the dts, with two factors including behavioral reactions and perceived feelings, explained 50.08% of the overall extracted variance. additionally, the results disclosed the acceptance of both internal consistency as well as construct validity. conclusions: the present study successfully translated and validated the dts into persian, demonstrating robust psychometric properties among alcohol consumers and drug users. the findings revealed two significant constructs, behavioral reactions and perceived feelings, which accounted for over 50% of the variance, highlighting the emotional and behavioral dimensions of distress tolerance in these populations. overall, the dts's strong internal consistency and confirmatory factor analysis (cfa) results suggest it is a reliable tool for assessing distress tolerance in persian-speaking individuals.
