Emotional and cognitive processes in psychotherapy are associated with different aspects of the therapeutic relationship.

Objective: In this naturalistic study we aimed to investigate the relationships between two central change processes (affective and cognitive) and two common relationship factors ("Confidence in the therapist" and "Confidence in the treatment"), which have been shown to impact outcomes in a clinical context. We also investigated whether these interrelationships varied across treatment orientations (i.e., cognitive or psychodynamic focused).

Method: The sample consisted of 631 patients with a primary anxiety or depressive disorder who were admitted to an inpatient program and treated with psychotherapy. The data consisted of weekly measures of cognitive (i.e., "rumination") and affective (i.e., "problems with emotional clarity") change processes as well as scores on Confidence in the therapist and Confidence in the treatment and symptom distress. A multivariate version of the latent curve model with structured residuals was used to investigate the within-patient effects of week-to-week changes in all variables.

Results: Initial analyses established that both problems with emotional clarity and rumination predicted symptom distress. Further, we found that higher Confidence in the therapist predicted higher emotional clarity (but not lower rumination) whereas higher Confidence in the treatment predicted lower rumination (but did not affect emotional clarity). Post hoc analyses found that these interrelationships varied across treatment orientation (i.e., cognitive vs. psychodynamic).

Discussion: The results indicate that patients' experience of the therapist is associated with emotional change processes, and that patients' experience of the coherence and meaningfulness of treatment, on the other hand, is associated with cognitive change processes. Implications for clinical practice are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
