Design outcomes

Secondary

MeasureTime frame
The secondary outcome measures are as follows. Symptom-related measures: GRID-HAMD-17 and MADRS, response rate (50 percent or greater improvement), remission rate (GRID-HAMD-17 score of 7 or less), and dropout rate. Satisfaction measure: CSQ-8J. Psychological-behavioral and neuroimaging measures: reaction time on the future thinking task (FT_RT), and changes in brain function and brain structure assessed by fMRI and structural MRI. Patient-reported outcomes: QIDS-J, SRS, SWLS, FS, RRS, EQ, and CBTSQ. Therapist-rated measure: CTRS-R. One recorded CBT session during the intervention period will be independently rated by an evaluator.
