Article Description: This study identified a pathway from in session process, and problem resolution, to post session change and final outcome. Two brief treatments for depression, one using client-centered (CC) and the other process-experiential (PE) interventions were compared on client process and outcome. The PE group showed significantly higher levels of experiencing, vocal quality and expressive stance, and greater problem resolution than the CC group in two of three PE interventions that were studied. Clients' Degree of Problem Resolution (DRS) correlated significantly with depth of experiencing, and sustained resolution over treatment resulted in better outcome.
