Reports of Therapy Skill Use and Their Efficacy in Daily Life in the Short-term Treatment of Depression.

Previous studies have shown that the use of therapy skills in between sessions is an important mechanism of symptom improvement. The current study expands this line of research by using a diary approach to examine the use of therapy skills in daily life. A sample of 39 depressed adults (85% female, mean age 38) were signaled twice per week throughout the course of either cognitive-behavioral therapy (CBT) or self-system therapy (SST).
