Arms Assigned Interventions
Experimental: Culturally congruent assessment and treatment
Outreach by phone to primary care patients interested in mental health referral. Engagement and evaluation approach conducted using the DSM-IV cultural formulation model. Same treatment choices as in control arm (medication, interpersonal psychotherapy, and combination treatment).
Behavioral: Culturally Congruent Assessment and Treatment
Referral, engagement, and treatment is done following the cultural formulation model in DSM-IV in which patients' views and expectations about depression treatment are included in the assessment and treatment process.
Active Comparator: Usual referral and treatment
Usual referral procedure from primary care: PC clinician gives patient information on how to access mental health care at research site. Usual engagement and evaluation approach without using cultural formulation model. Same treatment choices (medication, interpersonal psychotherapy, and combination treatment) as in experimental arm.
Behavioral: Culturally Congruent Assessment and Treatment
Referral, engagement, and treatment is done following the cultural formulation model in DSM-IV in which patients' views and expectations about depression treatment are included in the assessment and treatment process.

Detailed Description:

Major depressive disorder (MDD) is a type of depression that is characterized by a combination of symptoms that can interfere with the ability to work, study, sleep, eat, and enjoy activities that were once pleasurable. Studies have shown that individuals of Hispanic descent underutilize specialized mental health care services (SMHS), despite their need for it. In addition, Hispanic individuals have been associated with lower rates of retention in specialized mental health treatment. In particular, dropout rates from medication therapy for the treatment of MDD within SMHS are two to three times higher in Hispanics than in non-Hispanic whites. This study will develop and evaluate the effectiveness of a culturally-based program that aims to facilitate entry, retention, and successful treatment in specialized mental health services for Hispanics with MDD.

This open-label study will consist of four phases. Participants will be recommended for inclusion in the study upon receiving a diagnosis of MDD based on a standard health questionnaire completed in their primary care physician's office. Phase 1 of the study will entail an initial evaluation of the culturally congruent program of care for Hispanics with MDD (CCP-MDD). Participants will be placed in one of two focus groups, each composed of 8 to 10 people. One group will include individuals referred by their primary care physician. The other group will include family members of Hispanics with MDD. Discussions will focus on participants' understandings of depression-like illness, their treatment expectations for these conditions, and their perceived barriers to SMHS utilization. Information gathered in the focus groups will be used to develop a second version of CCP-MDD. Phase 2 of the study will evaluate the revised version of CCP-MDD and will include additional treatments with antidepressant medication, weekly interpersonal psychotherapy, or a combination of the two. Following treatment, participants will take part in a focus group, which will involve participant feedback.

Based on the information obtained in the focus groups and from clinical observations, a third version of CCP-MDD will be developed. In Phase 3, two sets of primary care offices will participate. One set will be assigned to the intervention arm, and receive the third version of the CCP-MDD intervention. A second set will be assigned to the control arm and receive usual referral to mental health services at the research site. All participants will be offered the same choice of treatments: antidepressant medication, weekly interpersonal psychotherapy, or a combination of the two. Treatment in both arms will be of the same duration, 18 wks. Focus groups will be held following treatment in order to obtain information about individuals' satisfaction or dissatisfaction with their care. Based on these findings, as well as clinical observations, a fourth and final version of CCP-MDD will be developed in Phase 4. All treatments will last a total of 18 weeks. A follow-up session will be held at Week 30 to assess depressive symptoms.
