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.

Purpose: There has been no comprehensive examination of how race/ethnicity and nativity intersect in explaining differences in lifetime prevalence of mental disorders among Asian, Black, Latino, and White adults. This study aims to estimate racial/ethnic differences in lifetime risk of mental disorders and examine how group differences vary by nativity.Methods: Survival models were used to estimate racial/ethnic and nativity differences in lifetime risk of DSM-IV anxiety, mood, and substance use disorders in a nationally representative sample of over 20,000 respondents to four US surveys.Results: Asians had the lowest lifetime prevalence of mental disorders (23.5%), followed by Blacks (37.0%), Latinos (38.8%), and Whites (45.6%). Asians and Blacks had lower lifetime risk than Whites for all disorders even after adjusting for nativity; Latinos and Whites had similar risk after adjusting for nativity. Risk of disorder onset was lowest for foreign-born respondents in years before migration. There were significant race/ethnicity and nativity interactions for mood and substance use disorders. Odds of mood disorder onset were higher for Whites with at least one US-born parent. Odds of substance use disorder onset among Asians were higher for US-born respondents; for Latinos, they were higher for those with at least one US-born parent.Conclusions: Parental foreign-born nativity is associated with a low risk of mental disorders, but not uniformly across racial/ethnic groups or disorders. Exposure to the US context may be associated with greater mental disorder risk for Latinos and Whites particularly. Investigations of cultural processes, including among Whites, are needed to understand group differences. [ABSTRACT FROM AUTHOR]

Background: This study describes the prevalence of comorbid physical and mental health problems in a national sample of US Latinos. We examined the co-occurrence of anxiety and depression with prevalent physical chronic illnesses in a representative sample of Latinos with national origins from Mexico, Cuba, Puerto Rico, and other Latin American countries.Method: We used data on 2,554 Latinos (75.5% response rate) ages 18 years and older from the National Latino and Asian American Study (NLAAS). The NLAAS was based on a stratified area probability sample design, and the sample came from the 50 states and Washington, DC. Survey questionnaires were delivered both in person and over the telephone in English and Spanish. Psychiatric disorders were assessed using the World Mental Health Survey Initiative version of the World Health Organization Composite International Diagnostic Interview (WMH-CIDI). Physical chronic illness was assessed by self-reported history.Results: Puerto Ricans had the highest prevalence of meeting criteria for any comorbid psychiatric disorder (more than one disorder). Puerto Ricans had the highest prevalence (22%) of subject-reported asthma history, while Cubans had the highest prevalence (33%) of cardiovascular disease. After accounting for age, sex, household income, number of years in the US, immigrant status, and anxiety or depression, anxiety was associated with diabetes and cardiovascular disease, in the entire sample. Depression and co-occurring anxiety and depression were positively associated with having a history of asthma but not with other physical diseases, in the entire sample. Interestingly, Puerto Ricans with a depressive disorder had a lower odds of having a history of cardiovascular disease than Puerto Ricans without a depressive disorder. The relationship between chronic physical and mental illness was not confounded by immigration status or number of years in the US.Discussion: Despite previous findings that link acculturation with both chronic physical and mental illness, this study does not find that number of years in the US nor nativity explain the prevalence of psychiatric-medical comorbidities. This study demonstrates the importance of considering psychiatric and medical comorbidity among specific ethnic groups, as different patterns emerge than when using aggregate ethnic measures. Research is needed on both the pathways and the mechanisms of comorbidity for the specific Latino groups. [ABSTRACT FROM AUTHOR]

In clinical practice, denial has long been thought to be a determinant of treatment initiation and retention; however, little empirical research has focused on denial as a mechanism. For example, denial has not been standardized or operationalized in epidemiological studies for mental health services research and, thus, the magnitude of the effects of denial on mental health care use are unknown. This study makes use of the "Mental Health Care among Puerto Ricans" study, a 3-wave island-based probability epidemiological study conducted from 1992 to 1998. For all the 3 waves, 2928 individuals participated (81.5% response). The analyses were limited to only those participants who were objectively determined to have a severe need for mental health care (n = 742). The findings from this study show that admitting to a mental health problem is related to the increased odds of using any mental health care, any specialty care, psychotropic drugs, and retention in mental health care, after adjusting for potential confounding. Similar patterns were observed even after the data were limited to those participants who did not previously seek mental health care, and the trends persisted when determining changes from denial to admitting a mental health problem. The study confirms that denial is a significant factor for treatment initiation and retention, particularly for Puerto Ricans, and denial should be considered an important mechanism in planning interventions to eliminate mental health care disparities.

This article examines problem recognition across ethnic groups by focusing on parental reports of mental health problems in adolescents. Data were collected from 1 youth (aged 11-17) and 1 caregiver from a community-based sample of households in the Houston metropolitan area. The sample was 4175 youths and their caregivers (37.8% European, 35.00% African, 25.4% Latino, and 1.8% other American). Indicators of mental health were perceived mental health, life dissatisfaction, and whether adolescents had a mental health problem in the past year. European Americans were more likely to rate the mental health of adolescents as fair or poor, were about twice as likely to report that adolescents were dissatisfied with their lives, and that adolescents had a mental health problem in the past year. Interventions to help minority families in the identification of youth's mental health problems may need to address cultural differences in the definition of mental health problems or in the benefit of labeling mental health problems that may serve as barriers to help-seeking.
