Relationship Between Satisfaction, Patient-Centered Care, Adherence and Outcomes Among Patients in A Collaborative Care Trial for Depression

Abstract

Collaborative care is known to improve satisfaction, patient-centered care, adherence, and depression symptom severity. However, associations among these outcomes have not been examined. Outcomes were measured at 6 months for 360 primary care patients with depression enrolled in a randomized trial of collaborative care. Main effects and mediation effects were examined using logistic regression analyses. Collaborative care significantly improved both satisfaction and patient-centered care. Patient-centered care did not mediate the positive effect that collaborative care had on satisfaction. Improvements in symptom severity partially mediated collaborative care's effect on satisfaction. Satisfaction did not mediate collaborative care's positive effect on antidepressant adherence.
