Understanding Latino Ethnic Identity Development: A Review of Relevant Issues

One of the most promising areas in cross-cultural psychology is the development of identity among various ethnic groups in the United States. This article has a twofold purpose. First, it offers the concept of ethnic identity as defined and studied within the social sciences — sociology, anthropology, and psychology — including a review of some of the recent work on ethnic identity development proposed by leading investigators in the field of psychology. The author discusses their generalizability across ethnic groups. Second, it presents a number of dimensions considered important in conceptualizing and studying Hispanic ethnic identity development. These include acculturation, the notion of biculturalism, and gender and generational differences. Implications for mental health practitioners and recommendations in the area of public policy are discussed

Lower Serum Testosterone Associated with Elevated Polychlorinated Biphenyl Concentrations in Native American Men

Background: Polychlorinated biphenyls (PCBs) and chlorinated pesticides are endocrine disruptors, altering both thyroid and estrogen hormonal systems. Less is known of action on androgenic systems. Objective: We studied the relationship between serum concentrations of testosterone in relation to levels of PCBs and three chlorinated pesticides in an adult Native American (Mohawk) population. Methods: We collected fasting serum samples from 703 adult Mohawks (257 men and 436 women) and analyzed samples for 101 PCB congeners, hexachlorobenzene (HCB), dichlorodiphenyldichloroethylene (DDE), and mirex, as well as testosterone, cholesterol, and triglycerides. The associations between testosterone and tertiles of serum organochlorine levels (both wet weight and lipid adjusted) were assessed using a logistic regression model while controlling for age, body mass index (BMI), and other analytes, with the lowest tertile being considered the referent. Males and females were considered separately. Results: Testosterone concentrations in males were inversely correlated with total PCB concentration, whether using wet-weight or lipid-adjusted values. The odds ratio (OR) of having a testosterone concentration above the median was 0.17 [95% confidence interval (CI), 0.05–0.69] for total wet-weight PCBs (highest vs. lowest tertile) after adjustment for age, BMI, total serum lipids, and three pesticides. The OR for lipid-adjusted total PCB concentration was 0.23 (95% CI, 0.06–0.78) after adjustment for other analytes. Testosterone levels were significantly and inversely related to concentrations of PCBs 74, 99, 153, and 206, but not PCBs 52, 105, 118, 138, 170, 180, 201, or 203. Testosterone concentrations in females are much lower than in males, and not significantly related to serum PCBs. HCB, DDE, and mirex were not associated with testosterone concentration in either men or women. Conclusions: Elevation in serum PCB levels is associated with a lower concentration of serum testosterone in Native American men

Culturally Adapted Behavioral Activation a Treatment Approach for a Latino Family

The scarcity of accessible culturally competent service providers and a general sense of mistrust in Eurocentric-based mental health settings exacerbate the lack of help seeking and effective therapeutic engagement for Latinos. Thus, clinical interventions that account for diverse values and worldviews may be an important step in the helpful treatment of U.S. Latino populations. Behavioral activation (BA), an evidence-based intervention for the treatment of depression, was recently evaluated through a preliminary clinical trial study in a community clinic primarily serving Spanish-speaking Latinos, and the results were promising. A culturally adapted version of BA was developed for Latinos, which took into consideration the cultural value of familismo (a collectivist worldview and preference for maintaining close connections to family); however, BA has not been previously applied to Latino families. The current case study presents the clinical treatment of a Mexican American family living in the southwest of the United States experiencing numerous stressors resulting in depressive symptoms. Specifically, this family sought therapy having experienced many negative life events, including stressors associated with institutionalized racism, their financial situation, and acculturation process. This led to a disruption of the family hierarchy, anger, unhappiness, fear, and isolation among family members. Outcomes of the intervention include a decrease in depressive symptoms and improved family communication and relationships by their involvement in activities such as attending cultural events in their community, family outings, and the children’s participation in extracurricular activities.</jats:p

Environmental Toxins and Depression in an American Indian Community

Abstract Polychlorinated biphenyls (PCBs) are a public health problem affecting many minority communities. We examined relationships between PCBs and depression among 306 adults on the Akwesasne Reservation (68% females; 18-79 years) exposed to PCBs through industrial contamination. Blood was collected to measure total PCB levels, which also were categorized based on level of chlorination and dioxin-like structure. The Center for Epidemiology Studies of Depression (CES-D) scale scores increased as terciles of measured PCB blood level increased, though increases were not significant (p\u3e0.05). While there are documented health effects of PCBs, these results, consistent with one previous study, demonstrate depression is not associated with PCB exposure. Further study of the mechanisms for successfully coping with such adverse circumstances is warranted

Exposure to an Environmental Toxin, Quality of Life and Psychological Distress

This study examined the effects of polychlorinated biphenyls (PCBs), a toxic substance considered carcinogenic in nature, on the socio-psychological well-being of a Native American community located in upstate New York. A sample of 353 men and women completed a demographics questionnaire and measures assessing quality of life, psychological distress and depression. Blood samples were obtained for chemical analyses of PCBs and thyroid hormone levels. Urine samples were obtained to conduct the analysis of homovanillic acid (HVA), a proxy for dopamine function. The results of the study revealed that PCB exposure, as measured by body burden levels, was not significantly related to distress and depression. Likewise, PCB exposure was not significantly related to job, family and personal aspects of quality of life. However, the study revealed that lower quality of life in each of these domains was significantly related to higher levels of psychological distress in this sample

Evidence of an Age-Related Threshold Effect of Polychlorinated Biphenyls (PCBs) on Neuropsychological Functioning in a Native American Population

Polychlorinated biphenyls (PCBs) have been suspected for some time of having adverse effects on neuropsychological functioning in humans. While there is evidence of slowing of cognitive function in children associated with exposure to PCBs, the evidence of comparable effects on adults is far less well understood. We report here on the neuropsychological evaluation of 277 Native American adults, ranging in age from 18 to 79, who were exposed to PCBs by way of environmental contamination in the St. Lawrence region of upstate New York. PCB body burden was estimated by 101 PCB congeners and neuropsychological functioning was assessed by a battery of 18 tests. Spline regression models were fitted to the latent variables of memory, motor function, and higher-order executive functioning. After adjusting for age, gender, and education the analyses revealed a threshold effect of PCBs at approximately 2 ppb. An age-by-PCB interaction effect was also observed for several variables which suggests that the threshold effect was largely confined to the age range of 40–79 and was not observable in the 18–40-year-old group. Implications of these results are discussed in comparison to previously published similar work with adults and in terms of its potential clinical meaningfulness

Cultural and linguistic competence: Welcome challenges from successful diversification

The increasing numbers of ethnically diverse professionals is filling a need for service provision in agencies that provide mental health services for a diverse clientele. However, the rapid shift in professional demographics provides a sharp generational contrast; these emerging psychologists are placed in potentially ethically charged positions before their careers truly begin as a result of the gap between institutional resources (materials and supervisors) and trainees\u27 specialized needs. The lead article reviews a broad array of points to consider when a supervisee is providing services in the native language of the client and does not know that language. The three invited commentaries highlight (a) the role of language in emotion and subsequent implications for treatment and supervision, (b) the slow institutional development to meet the training needs of emerging therapists that will treat ethnically diverse clients, and (c) the importance of following decision-making models to inform ethical supervisory practice when there is a language mismatch
