The relation of baseline skills to psychotherapy outcome across diverse psychotherapies.

Objective: We explored whether patients with varied levels of baseline deficits in compensatory skills and self-understanding had different outcomes across cognitive and dynamic therapies.

Method: The assessment battery was administered at intake and termination (N = 97; 66% female, 81% Caucasian). We conducted regression analyses predicting symptom change from baseline levels of self-understanding and compensatory skills. We also evaluated the interaction between baseline skill levels and treatment condition in the prediction of psychotherapy outcome.

Results: There was a significant interaction between treatment group and baseline compensatory skills in the prediction of Hamilton Depression Rating Scale (HAMD) symptom change, F(1,76) = 4.59, p = .035. Baseline deficits in compensatory skills were significantly related to symptom change for patients who received cognitive treatment, ηρ = .40, p = .037, while baseline levels of self-understanding were not significantly predictive of treatment outcome in either condition. Baseline skill variables did not predict symptom change as measured by the HAMA.

Conclusions: The findings support a capitalization model of cognitive therapy, whereby patients with relative strengths in compensatory skills at baseline have better treatment outcomes.
