Conceptualizing aetiology underpinning an individual’s substance use disorder (SUD) not only facilitates insight and understanding, but also serves to identify targets for treatment and aid practitioners in selecting the most appropriate interventions. There is now a wealth of literature on aetiology and treatment approaches, and in more recent years, also literature to support the concept of ‘recovery’ from a condition which was previously thought of as a chronic, relapsing condition. The burgeoning literature around research into recovery is revealing how recovery can best be defined and what factors might be associated with recovery from SUD. To add further to this growing body of literature, a new six-domain, explanatory biopsychosocial model of substance dependence and recovery, the Lifestyle Balance Model (LBM) is proposed. Based on research findings and theory reported in the literature, the LBM is a generic model depicting six domains of biopsychosocial functioning and includes within it the role of lifestyle. The LBM has been constructed as a domain model, allowing conceptualisation of the relationships between the six domain areas that perpetuate dependence and may also be associated with recovery from SUD, providing service users and clinicians with a tool for the delivery of case formulation and identification of target areas for intervention.
