An ethnical study on the relationship between well-being and dyadic adjustment with the mediation role of satisfaction with life among Baluch male drug users

This study aimed to evaluate the relationship between well-being and dyadic adjustment, with life satisfaction serving as a mediator among Baluch male drug users in Zahedan city, located in southeastern Iran. For this study, 224 Baluch male drug users were selected from the city of Zahedan through a convenience sampling method. The data gathering involved the Well-Being Questionnaire (WBQ), the Dyadic Adjustment Scale, and the Life Satisfaction Scale. The findings from the structural equation model (SEM) showed that happiness, optimism, and life satisfaction had a notable direct impact on dyadic adjustment and life satisfaction (<i>p</i> < .05). Satisfaction with life had a notable impact on dyadic adjustment (<i>p</i> < .05). Life satisfaction significantly mediated the connection between happiness and optimism with dyadic adjustment, and it also mediated the relationship between life satisfaction and dyadic adjustment significantly (<i>p</i> < .5). The remaining direct and indirect effects were insignificant. It is determined that life satisfaction, happiness and optimism can influence dyadic adjustment among Baluch men who abuse substance. Consequently, addiction healthcare facilities in Baluchestan, Iran, should focus on the psychological well-being of substance abusers.
