This qualitative case study explored one client’s recovery from borderline personality disorder, trauma, and problem gambling. The client attended 18 months of integrative treatment and was followed for 5 years. The study included 106 data points of both client and therapist data. We identified three phases to treatment. First, alliance formation and normalization appeared as mechanisms, and the client experienced dependence. Second, working alliance and countertransference appeared as mechanisms, and the client experienced reduced gambling and suicidal ideation. Third, external controls and increased opportunity appeared as mechanisms, and "moving into the world" was the client experience. The findings give preliminary support to a phase-based constructivist treatment including trauma assessment to normalize self-feelings, countertransference work to support motivation for restraint, and case management principles to support continuity of change efforts.
