Unveiling Substance Use Patterns and Dysfunctional Family Dynamics Among Adults in Rehabilitation

Substance use disorder is commonly approached as an individual condition; however, increasing evidence highlights the role of family environments in shaping substance use behaviors. This study examines how dysfunctional family dynamics influence substance use patterns among adults undergoing rehabilitation in the Philippines, addressing the gap between individual-focused treatment and relational influences A qualitative case study design was employed involving five participants selected through purposive sampling. Data were collected using semi-structured interviews, the McMaster Family Assessment Device, and secondary records. Thematic analysis was applied to identify recurring patterns across cases. Findings revealed four consistent patterns: early initiation of substance use, coping-driven use, progression from experimentation to dependence, and delayed help-seeking. These patterns were strongly associated with family conditions such as emotional neglect, poor communication, lack of supervision, trauma, and substance use modeling. Across cases, substance use emerged as a response to sustained emotional and relational difficulties. The study demonstrates that substance use is not solely an individual behavior but a relationally shaped process. Findings highlight the importance of integrating family-centered approaches into rehabilitation programs to improve long-term recovery outcomes. These results provide a basis for developing culturally grounded intervention strategies within family contexts.
