There has been a growing interest in the substance abuse treatment field in bringing together the treatment and research communities. While dialogues about logistical and philosophical issues are important, the development of shared core concepts could potentially be quite helpful in facilitating communication and creating common treatment and research goals. It is the contention of this paper that all psychosocial and, potentially, pharmacological treatments ideally address, in part or in full, three aspects of the self--the capacity to regulate emotional and behavioral expression, the ability to engage in future-oriented, goal-directed behavior, and the development of nonaddict and/or recovery-oriented identities. Examples from the research and treatment literature are provided.
