Relationship between substance use-associated stigma and executive dysfunction

Abstract

ABSTRACT Background Among individuals who use substances, the perceived stigma of substance use harms their quality of life and may be an obstacle to quitting. We explored the effect of the stigma perceived due to substance use on executive functioning. Methods This cross-sectional study involved 80 individuals who used substances and sought to quit while admitted to a public neuropsychiatric hospital in south Iran in March 2022. Data were collected using the Barkley Executive Function Questionnaire and the Stigma Scale. Statistical analyses were done using SPSS v. 25. Results The participants’ mean age was 36.56 ± 9.37 years, and most (85.0%) were males. Among them, 28 (35%) used narcotics, 7 (8.8%) used stimulants, and 45 (56.3%) used multiple substances. Increased total sigma scores correlated with deficits in self-management to time, self-organization/problem-solving, self-regulation of emotion, self-motivation, self-restraint, and total executive function. Moreover, each stigma dimension had some correlations with executive dysfunction or its subscales. Conclusions Self-perceived stigma is directly linked with executive dysfunction in individuals who use substances and seek to quit. Since stigma and executive function both play essential roles in addiction treatment success, interventions should be adjusted to reduce self-perceived stigma and executive function deficits among individuals who use substances.
