Standing on the shoulders of a giant: Development of an outcome management system based on the dose model and phase model of psychotherapy

Ken Howard's major contributions to psychotherapy research include his studies of the sequence (phase model), rate (dose-response model), and predictability (expected treatment response modeling) of changes that occur during psychotherapy. This body of work formed the foundation for the development of an outcomes management system: Treatment Evaluation and Management (TEaM). The authors describe the development of TEaM measures corresponding to the central constructs of the phase model: subjective well-being, symptoms, and functional disability. Scale scores are combined to derive a composite score, the Behavioral Health Status (BHS) index, which provides a global measure of a patient's psychological status and functioning. The authors present psychometric information about each of the measures and the composite BHS index. Ken was working on finalizing the TEaM at the time of his death. Thus, this measurement approach is his final contribution to the field of outcomes management.
