Brief Summary:
The purpose of this study was to examine the effect of a new disease management model for depression, the Collaborative Depression Management Program (CDMP), designed to improve clinical outcomes and increase depression treatment in general medical settings.

Condition or disease Intervention/treatment Phase
Major Depression Other: Collaborative Care Not Applicable

Detailed Description:

Clinically depressed individuals that could benefit from newer treatments for depression often do not receive care. Low treatment rates are of particular concern since depression is projected to be the second leading cause of disability worldwide by 2010. Major depression has been the focus of numerous intervention studies with primary care patients during recent years. However, despite advances in the development and testing of quality intervention models for depression treatment, very little is known about the effectiveness of interventions with Latinos. This is important because Latinos are less likely than whites to receive depression treatment, even though the rates of depression are similar for both groups. A major public health challenge is to make available the benefits of intervention developments in depression treatment for all groups in society. As a first step, we examined the impact of a quality depression intervention with Puerto Ricans. The specific aims were:

  1. To examine the effect of a Collaborative Depression Management Program in reducing depressive symptoms, improving quality of life, and decreasing health-related functional impairment among Puerto Rican patients in general medical settings.
  2. To determine whether a Collaborative Depression Management Program is effective in improving satisfaction with care and reducing barriers to depression treatment among Puerto Rican patients in general medical settings.

This study employed a randomized experimental design. Depressed patients receiving general medical care were assigned to one of two conditions: 80 to the Depression Management Program and 80 to treatment as usual. All subjects completed assessments at baseline, week 8, week 16 and week 24. Our overall programmatic goals were to increase the likelihood that depressed patients receive care and to make available for the Puerto Rican community advances in the treatment of major depression.
