Do Latino and non-Latino White Medicaid-enrolled adults differ in utilization of evidence-based treatment for major depressive disorder?

Homework completion via telephone and in-person Cognitive Behavioral Therapy among Latinos

Homework completion in cognitive behavioral therapy (CBT) for depression is an integral ingredient in treatment that often goes unreported. Furthermore, many studies of homework completion focus on patient adherence without considering the therapists' role in reviewing and reinforcing this behavior. No studies to date have assessed the relationship between homework variables and outcomes among Latinos receiving CBT for depression. Since this population has often been difficult to engage in CBT, this study aims to assess whether homework completion and therapist review of homework are related to improved outcomes in a CBT intervention (telephone or in person) for Latinos with depression. We found that higher homework completion was significantly related to lower depression scores at the end of final treatment (as measured by PHQ-9) (B = -1.38, p < 0.01). However, the significant association of homework with depression went away when clinician review of homework was included in a subsequent step of the model (B = -0.42, p = 0.45). The number of times a clinician actively reviewed homework was still significantly related to a decrease in PHQ-9 when controlling for demographic factors (B = -1.23, p < 0.01). This study found that homework is a predictor of improved outcomes in CBT for depression but highlights the role of therapists reviewing homework as a predictor of lower depression symptoms among Spanish speaking Latinos from low socioeconomic backgrounds.

A preliminary RCT of CBT-AD for adherence and depression among HIV-positive Latinos on the U.S.-Mexico border: the Nuevo Día study

We conducted a preliminary RCT among 40 HIV-positive Latinos of Mexican descent on the U.S.-Mexico border who indicated imperfect adherence and depressive symptomatology. Participants were randomly assigned to culturally adapted cognitive-behavioral therapy for adherence and depression with an alarmed pillbox or usual care. Outcomes were depressive symptoms (self-report and blind clinician ratings), adherence (self-report and electronic pillbox), and biological markers. The intervention, delivered in English and Spanish, proved feasible and acceptable. Generalized estimating equations in intent-to-treat analyses showed some effects of "moderate" to "large" size, with maintenance over time. For example, intervention (vs. control) participants demonstrated at post-intervention a greater drop in BDI scores (OR = -3.64, p = 0.05) and greater adherence according to the electronic pillbox (OR = 3.78, p = 0.03). Biological markers indicated some relative improvement for CD4 count but not VL. The promising results suggest a larger trial to determine efficacy is warranted.

Translating knowledge to practice: optimizing the use of guidelines

Guidelines support health care decision-making but continue to be underused, therefore more research is needed on how they can be better developed and implemented. The same is true of mental health care, for which there is recent growing interest in improving care delivery and associated outcomes by optimizing the use of mental health care guidelines. This editorial describes the key concepts from accumulated research on guideline implementation to suggest a number of avenues for research on implementation of mental health care guidelines.
