Reflections on volatile substance dependency treatment. Negotiating the boundary between inner and outer reality

A brief review of the causal and treatment literature relating to volatile substance dependency suggests the interaction between individual and system requires careful attention and understanding. A model is tentatively and provisionally adumbrated to help clarify the main factors involved from a dynamic biopsychosocial perspective. Ego boundary disturbances emerge from and reciprocally influence behaviour and social interactions. These disturbances can be avoided temporarily, although inevitably deepened in the long-term, by substance dependence. Two case examples, selected because they differ in many respects, including relative treatment effectiveness, illustrate this integrative perspective. The discussion focuses on explaining the differing outcomes in terms of the extent to which the inner-outer boundary is open to modification and how far it can be successfully negotiated and clarified. A major factor in differentiating between inside and outside is thought to be causal perceptions or "attributions." Successful differentiation tends to facilitate change, as opposed to reinforcing maladaptive homeostasis. Key issues for therapists overlap with addictions treatment in general, including emotional blocks or barriers in patients, difficulty engaging systems in a strategic manner, and countertransference problems. It is argued that these difficulties in therapy might respond to integrative psychotherapeutic responses, provided the differences in perspective are sufficiently understood.
