Table 3. Performance of circuit predictor models using 2-month cognitive control circuit changes to predict future improvements of treatment outcome for hypothesis 3.
Circuit model: using 2-month cognitive control circuit activity changes as well as baseline demographic and symptom characteristics as predictors to predict treatment outcomes at 6, 12, and 24 months. Baseline model: excluding 2-month cognitive control circuit measures and only including baseline demographic and symptom characteristics. Problem-solving ability was measured using the SPSI; depression symptoms were measured using the SCL-20. rp, Pearson correlation coefficient; MAE, mean absolute error.
