Latinos are underrepresented in clinical trials, where they encounter challenges in participation and a lack of effective recruitment and retention strategies. For Latino migrants with mental health and substance use problems, these challenges are even greater. Analyzing results from a multicenter randomized clinical trial for Latino migrants with mental health and substance use problems in Boston, Massachusetts, USA as well as Madrid and Barcelona, Spain, we describe six retention strategies used to facilitate participant engagement in follow-up assessments, and report the sociodemographic, clinical, and educational factors associated with research assessment completion. Among 341 randomized participants, 77% completed the 12-month follow-up and 75% completed at least 3 of the 4 follow-up assessments. Having a high school diploma, being recruited at community centers versus other sites, and having a less severe mental health condition were significantly associated with completing more follow-up interviews. Rigorous and customized methods reflecting participant's individual context can bolster research assessment completion for diverse Latino populations with behavioral health concerns.

We identify the prevalence and correlates of posttraumatic stress (PTSD) symptoms and their relationship to alcohol and substance use disorders (AUD/SUD) among Latino immigrants in two countries. A screening battery assessing PTSD symptoms (PCL-C), alcohol use (AUDIT), drug abuse (DAST), and psychological measures was administered to 562 Latino immigrants recruited in clinics. We used logistical regression analyses to evaluate the relationship between PTSD symptoms and AUD/SUD. Prevalence of elevated PTSD symptoms was high (53.7 % in Boston, 47.9 % in Madrid and, 43.8 % in Barcelona). Screening positive for psychological measures was significantly correlated to screening positive on the PCL-C (p < 0.001). Significant gender differences in risk of AUD/SUD were moderated by PTSD symptoms. Presence of any PTSD symptoms predicted problems with benzodiazepine misuse. Given the high rates of co-morbidity between PTSD symptoms and AUD/SUD, we recommend early interventions for dual pathology for Latino immigrants with trauma history. [ABSTRACT FROM AUTHOR]

Despite recent growth in the variety of antidepressant medications available, many patients discontinue medication prematurely for reasons such as nonresponse, side effects, stigma, and miscommunication. Some analysts have suggested that Latinos may have higher antidepressant discontinuation rates than other US residents. This paper examines Latino antidepressant discontinuation, using data from a national probability survey of Latinos in the USA. In this sample, 8% of Latinos had taken an antidepressant in the preceding 12 months. Among those users, 33.3% had discontinued taking antidepressants at the time of interview, and 18.9% had done so without prior input from their physician. Even controlling for clinical and other variables, patients who reported good or excellent English proficiency were less likely to stop at all. Patients were also less likely to stop if they were older, married, had public or private insurance, or had made eight or more visits to a nonmedical therapist. [ABSTRACT FROM AUTHOR]

The present study examines the extent of turnover in mental health provider networks within public sector managed mental health care over a 1-year period and its association to provider and practice characteristics. Telephone interviews were conducted with a sample of mental health services providers listed the previous year in the networks of the 3 public sector managed mental health care organizations operating in Puerto Rico. Thirty-one percent of respondents had dropped out of networks. The drop-out rate was significantly associated (P < or = .05) with increasing number of years in practice and decreasing years under contract. A nonsignificant trend was observed, suggesting that providers with subspecialty training are less likely to drop out. The results may be signaling an emerging problem in public sector managed mental health care. Stability of provider networks should be monitored by state agencies contracting out mental health care.

Although a health advantage in hypertension has been documented among Latinos, this advantage appears to be eroding. Of particular concern is the observation that Latinos are less likely to be screened and treated for hypertension and to having it controlled. Scholars have suggested that, above and beyond individual-level factors, neighborhood characteristics may be important predictors of health and health care. We analyzed 2001-2003 data from the Chicago Community Adult Health Study to examine (a) the relationship between the Latino and immigrant composition of neighborhoods in Chicago and several outcomes among Latinos: having hypertension, utilizing hypertension-related health care, and being treated for hypertension; and (b) whether there was a differential effect of neighborhood Latino/immigrant concentration by language of interview and nativity status. We controlled for additional neighborhood characteristics relevant to hypertension and to the availability and accessibility of health care resources. Neighborhoods with higher concentrations of immigrants and Latinos were associated with Latinos having lower odds of hypertension (OR = 0.60, p = 0.03). However, among those with hypertension, our results point to deleterious effects on hypertension care (OR = 0.55, p = 0.06) and treatment (OR = 0.54, p = 0.04) associated with living in neighborhoods with higher concentrations of immigrants and Latinos. We detected no significant interaction effects between immigrant/Latino neighborhood composition and language of interview or being an immigrant in this sample. These results suggest that improving access to care for Latinos with hypertension requires enhanced placement of community clinics and other safety-net health centers in neighborhoods with higher proportions of immigrants and Latinos.
