University of Missouri--Kansas City, 2020The purpose of this study was to examine the implementation and effectiveness of Cognitive Enhancement Therapy (CET) within a real-world, community mental health program. Evidence-based programs for people with schizophrenia and other serious mental illnesses are not widely available for eligible clients. Thus, real-world research is essential to address this underutilization of needed programs. This study intended to describe implementation of a 12-month version of CET, including descriptive participant, clinician, and setting information, as well as to test the program effectiveness. Thirty-four individuals who engaged in CET participated in the study. The majority of participants had a schizophrenia or schizoaffective disorder diagnosis. Results indicated that eligible participants attended and engaged with the program, and the majority reported high satisfaction. Implementation of CET was bolstered with funding to support clinician training and utilization of a train-the-trainer model. Using an intent-to-treat model, effectiveness was partially supported; Participants improved in attention, verbal memory, and visual memory, as well as several domains of positive and negative symptoms. This study was the first comprehensive evaluation to demonstrate that CET was successfully and effectively implemented in a real-world program. Research and clinical implications are discussed.Overview -- Review of the literature -- Methodology -- Results -- Discussion -- Tables and figures -- Appendix A.
