The primary research objective of the Psychotherapy Program is to determine which psychotherapeutic treatments are the most effective for different patient problems. A secondary research objective is to understand the mechanisms that underlie differential effectiveness. We are dedicated to using the highest scientific and professional standards to achieve these ends. Program members study the most current and successful psychotherapeutic techniques available in an effort to advance the research, clinical, and educational goals of the UBC Psychotherapy Program. Several different strategies are used to investigate the effectiveness of different psychotherapies and their change mechanisms. These include randomized controlled trials, process analyses, and comprehensive case examinations. A wide variety of short-term, time-limited psychotherapies, that represent different theoretical orientations (e.g., psychodynamic, cognitive-behavioural, interpersonal) and treatment formats (e.g., individual, group, partial hospitalization), are studied. Government (federal, provincial) organizations, private foundations, and local hospitals fund our research.
