The Melbourne Study of Psychoanalytic Psychother-apy examined the implementation, lived experience, and perceived therapeutic gains of psychoanalytic psychother-apy in a low-cost, private-sector community clinic. A first in Australia, this 8-year demonstration project allowed natural-istic study of the impact and process of intensive, long-term, time-limited psychoanalytic psychotherapy delivered to self-referred adults by clinicians with a common theoretical frame of practice. Presented in three papers, the research employed the RE-AIM planning and evaluation framework, using complementary quantitative and qualitative methods, to study the psychotherapy service in terms of Reach, Effec-tiveness, Adoption, Implementation and Maintenance. This first paper reports the Reach of the program to be 67% for those presenting for assessment for psychoanalytic psycho-therapy, with Adoption of the full 2-year treatment program being 60%. Improvements in mental health and life function-ing provided quantitative evidence of Effectiveness for those completing the 2-year treatment program, with Maintenanceat 8-month follow-up.
