Abstract
<jats:p>Substance use disorder (SUD) is a disease that affects not only the individual but also the family system in a multidimensional way. This chapter addresses the psychosocial impacts experienced by the families of individuals living with addiction, their help-seeking processes, and the dynamics of their participation in treatment, with a specific focus on the context of Türkiye. The literature shows that families struggle to cope with feelings associated with addiction, such as stress, guilt, shame, and helplessness, but that effective participation in the treatment process both supports the individual’s recovery and strengthens family functioning. The evidence-based effects of family therapies and psychoeducational models in addiction treatment are discussed, emphasizing the importance of culturally sensitive approaches in intervention processes. Furthermore, the current state of addiction-related services in the Turkish context, the limitations of family-based practices, and areas for improvement are examined. This chapter concludes with recommendations for future research regarding the development of family-centered, culturally sensitive, and evidence-based policy frameworks.</jats:p>
