Addiction can be a manifestation of dysfunctional relationships and interactions in the family. In such situations, the family, with its complex network of relationships and behavioural interactions, is considered the most suitable unit for intervention. Family therapy focusses on the patterns of communication within the family and helps the family understand the dynamics and how these intersect with the family member’s addiction. Some examples of such interventions include brief strategic family therapy, multidimensional family therapy (MDFT), and multisystemic therapy (MST). While the effectiveness evidence of many of these family interventions for addiction is robust, their reach is limited, primarily due to implementation barriers such as limited human and financial resources. Increasing access to such interventions will require expanding effectiveness research to the developing world and developing and testing low-cost interventions that are suitable for scaling up in low-resource settings.
