However, the intricacies of this mechanism remain obscure.AimThis study investigates the potential mediating role of psychological flexibility in the relationship between distress tolerance and perceived stress among individuals with SUD.MethodThis cross-sectional study evaluated 187 individuals with SUD, selected through non-probability convenience sampling, using the Introductory Information Form, the Perceived Stress Scale, the Distress Tolerance Scale and the Acceptance and Action Questionnaire-Substance Abuse. Data analysis was conducted using SPSS 25 and further refined with Jamovi 2.4.14, employing advanced mediation analysis techniques.ResultsSignificant relationships were found between distress tolerance, perceived stress and psychological flexibility. Mediation model analysis showed that psychological flexibility mediated the relationship between distress tolerance and perceived stress.DiscussionThis study revealed that higher distress tolerance, higher psychological flexibility and lower perceived stress were associated. As individuals adopt a more flexible and accepting attitude towards distressing situations, they perceive stressful events as less threatening and more manageable.Implications for PracticeThe study suggests the need for psychiatric and mental health nursing practice and education to incorporate strategies to increase psychological flexibility.eninfo:eu-repo/semantics/closedAccessArticleNovember3955259010.1111/jpm.13140WOS:001356835800001Q1
