Abstract
There is little evidence regarding which therapist strategies promote cognitive change in cognitive therapy (CT) of depression. Drawing from a sample of CT patients, we selected two consecutive sessions for which patients reported markedly different amounts of cognitive change (CC; i.e., a low and high cognitive change session). We then investigated whether four observer-rated psychotherapy process variables differentiated high and low CC sessions. Our analyses focused on 62 patients with large session-to-session differences in self-reported CC. Results from single predictor models showed the therapeutic alliance and therapists’ use of cognitive methods predicted high versus low CC session type. In a model including multiple predictors, only cognitive methods remained significant. These findings are consistent with the view that cognitive methods promote CC in CT.

Notes
Multiple patients near the 50th percentile had the same maximum absolute value of CC difference scores. We opted to select the patients with maximum scores greater than these values. This resulted in selecting 62 patients representing the top 49% of session-to-session shifts in CC.
Using data from the 62 included patients only, we calculated the z-score for high and low cognitive change sessions for each patient. The average of these scores was 0.91 for high CC sessions, which corresponds to the 82nd percentile of all CC scores in this group. For low CC sessions, the average was − 1.88, which corresponds to the 3rd percentile of CC scores in this group.
