Meaning-Centered Psychotherapy (MCP) is a manualized, evidence-based intervention designed to help cancer patients to find meaning and alleviate distress. Meaning-Centered Psychotherapy Training (MCPT) is a multicomponent program for cancer care clinicians that consists of didactics, group experiential learning, and role-plays with simulated patients to learn MCP and acquire skills to deliver it in real-world oncology settings. The efficacy and impact of MCPT for multidisciplinary cancer care clinicians to learn and disseminate MCP is described and evaluated. A multilevel evaluation based on the RE-AIM framework was utilized to assess the efficacy of the MCPT program over the initial 5 years of the program. The outcomes of the evaluation supported MCPT goals. Three hundred forty-two participants attended MCPT. Overall satisfaction measured in the post-training assessment was high. Significant increases in MCP skills were demonstrated by participants over the course of the role-play sessions, and participants showed significant improvements in pre/post-training MCP knowledge assessment scores, as well as significant increases in self-reported overall MCP skills and core competencies. Follow-up survey responses indicate that MCP trainees were utilizing MCP, had made changes to their clinical practice, and progressed on individual implementation goals. During the first 5 years, the MCPT program was successfully developed, established, implemented, and shown to be effective in the dissemination of MCP across the RE-AIM domains. Future directions for training and implementation research include increasing diversity of providers and investigating the impact of the program on patient outcomes.
