Racial discrimination and the stress process.

The unique and combined effects of chronic and daily racial discrimination on psychological distress were examined in a sample of 174 African American doctoral students and graduates. Using a daily process design, 5 models of the stress process were tested. Multilevel random coefficient modeling analyses revealed that chronic exposure to racial discrimination predicted greater daily discrimination and psychological distress. Further, results show that differences in daily discrimination and negative events accounted for meaningful variation in daily distress responses. Finally, findings indicate that daily discrimination and negative events mediated the relationship between chronic discrimination and psychological distress. The study provides support for the need to measure chronic strains as distinctive from daily stressors in the lives of African Americans.

Racial microaggressions and daily well-being among Asian Americans.

Although epidemiological studies and community surveys of Asian Americans have found that lifetime occurrences of racial discrimination are associated with increased risk for psychological morbidity, little is known about how exposure to racial discrimination is patterned in everyday life. Extrapolating from previous qualitative research (Sue, Bucceri, Lin, Nadal, & Torino, 2007), this study presents data on the prevalence and psychological correlates of everyday racial microaggressions that reflect the Asian American experience. Measures of positive affect, negative affect, somatic symptoms, and racial microaggressions were completed by 152 Asian Americans each day for up to 14 consecutive days. Approximately 78% of participants reported some form of racial microaggression within the 2-week study period. Multilevel analyses indicated that elevations in daily microaggressions, as well as greater microaggressions on average, predicted increases in somatic symptoms and negative affect. Implications of these findings for racial microaggression research and clinical practice are discussed.

Differential Effects of Perceived Discrimination on the Diurnal Cortisol Rhythm of African Americans and Whites

The current study considered the influence of perceived discrimination on the diurnal cortisol rhythm of 50 African American older adults and a matched comparison groups of 100 Whites (M(age)=56.6; 58% female). The role of socioeconomic status (SES) as a moderator of the effects of discrimination on the diurnal decline was also considered for each group. In support of the idea that perceptions of unfair treatment take on a unique meaning for stigmatized minority groups, results suggest that perceived discrimination is associated with a flatter (less healthy) diurnal slope among Whites but a steeper (more healthy) diurnal slope among African Americans. Perceived discrimination was also found to be more strongly associated with a steepening of the diurnal slope among lower SES African Americans than higher SES African Americans.

Childhood Cumulative Risk and Obesity: The Mediating Role of Self-Regulatory Ability

Objectives: We tested whether early childhood risk exposures are related to weight gain in adolescence and evaluate an underlying mechanism, self-regulatory behavior, for the risk-obesity link. Methods: Cumulative risk exposure to 9 sociodemographic (eg, poverty), physical (eg, substandard housing), and psychosocial (eg, family turmoil) stressors was assessed in 244 nine-year-old children. BMI was calculated at age 9 and then 4 years later. At age 9, children’s ability to delay gratification as an index of self-regulatory behavior was assessed. Path analyses were then estimated to evaluate our mediational model (Cumulative risk → Self-regulation → BMI) over a 4-year period in a prospective, longitudinal design. Results: Nine-year-old children exposed to a greater accumulation of multiple risk factors show larger gains in adiposity over the next four year period, net of their initial BMI. These gains in BMI during early adolescence are largely accounted for by deteriorated self-regulatory abilities among children facing more cumulative risks. Conclusions: Early childhood risk exposure leads to larger gains in BMI in adolescence. Given the importance of childhood adiposity to the development of obesity later in life, understanding the underlying mechanisms that link early experience to weight gain is an essential task. Deficiencies in self-regulation in response to chronic stress appears to be an important agent in the obesity epidemic.

Poverty and Health The Mediating Role of Perceived Discrimination

Social-class discrimination is evident in many societies around the world, but little is known about its impact on the poor or its role as an explanatory variable in the link between socioeconomic status and health. The current study tested the extent to which perceived discrimination explains socioeconomic gradients in physical health. Participants were 252 adolescents (51% male, 49% female; mean age = 17.51 years, SD = 1.03 years) who participated in Wave 3 of an ongoing longitudinal study focusing on the developmental consequences of rural poverty. Physical health was operationalized as allostatic load, a measure of cumulative wear and tear on the body caused by overactivation of physiological systems that respond to stress. Mediation analyses suggested that 13% of the effect of poverty on allostatic load is explained by perceived discrimination. The findings suggest that social-class discrimination is one important mechanism behind the influence of poverty on physical health.

Cumulative risk and adolescent's internalizing and externalizing problems: The mediating roles of maternal responsiveness and self-regulation.

The purpose of the present study was to examine longitudinal associations among maternal responsiveness, self-regulation, and behavioral adjustment in adolescents. The authors used structural equation modeling to test a model that demonstrates that the effects of early cumulative risk on behavioral problems is mediated by maternal responsiveness and self-regulation. Furthermore, the authors examine the contributions of cumulative risk and maternal responsiveness on childrens self-regulatory abilities. The study uses a 3-wave longitudinal design with multiple measures of risk and self-regulation from multiple observers. Data were collected from adolescents (N = 265, male = 140) and their parents at age 9, 13, and 17. Results suggest that the mediation hypothesis held true for externalizing, but not internalizing problems. Furthermore, cumulative risk and maternal responsiveness contributed uniquely to childrens self-regulation abilities. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

Environmental Volunteering and Health Outcomes over a 20-Year Period

PURPOSE This study tested the hypothesis that volunteering in environmental organizations in midlife is associated with greater physical activity and improved mental and physical health over a 20-year period. DESIGN AND METHODS The study used data from two waves (1974 and 1994) of the Alameda County Study, a longitudinal study of health and mortality that has followed a cohort of 6,928 adults since 1965. Using logistic and multiple regression models, we examined the prospective association between environmental and other volunteerism and three outcomes (physical activity, self-reported health, and depression), with 1974 volunteerism predicting 1994 outcomes, controlling for a number of relevant covariates. RESULTS Midlife environmental volunteering was significantly associated with physical activity, self-reported health, and depressive symptoms. IMPLICATIONS This population-based study offers the first epidemiological evidence for a significant positive relationship between environmental volunteering and health and well-being outcomes. Further research, including intervention studies, is needed to confirm and shed additional light on these initial findings.

Prospective Predictors of Positive Emotions Following Spousal Loss

Whereas theoreticians are interested in modeling how bereavement contributes to health, the bulk of research on spousal bereavement is conducted after a loss has occurred. Using prospective longitudinal data, this study examined the extent to which positive emotion following spousal loss varies on the basis of preloss characteristics of the bereaved spouse and the marital relationship prior to loss. Analyses are based on the National Survey of Midlife Development (MIDUS), a 2-wave panel survey of adults in the contiguous United States. Results indicate that compared with continuously married controls, widowed participants experienced a significant decline in positive emotion within 3 years following loss. Conversely, no significant declines in positive emotion were evident among widowed persons with greater preloss trait resilience or greater marital strain. Results provide support for the notion that adjustment to loss may be linked to factors that precede actual loss.

Measurement of Ethnic Identity: Recurrent and Emergent Issues

Recent years have witnessed a proliferation of research on ethnic identity. To date, this research has been dominated by individual differences methods. Both Gaines, Bunce, Robertson, Wright, Goossens, Heer, et al. (this issue) and Juang and Nguyens (this issue) examination of the psychometric properties of the Multigroup Ethnic Identity Measure (MEIM; Phinney, 1992) demonstrate the promise of such methods. In this commentary, we briefly consider the measurement issues raised by Gaines et al. (this issue) and Juang and Nguyen (this issue). We then highlight the importance of taking a process approach to understanding ethnic identity. Our goal is to highlight new developments and unanswered questions. In so doing, we hope to detail the ways in which ethnic identity research has evolved over the past two decades and provide an impetus for the empirical investigation of unresolved issues.

The Social Costs of Academic Success Across Ethnic Groups

This study explores the longitudinal association between academic achievement and social acceptance across ethnic groups in a nationally representative sample of adolescents (N = 13,570; M(age) = 15.5 years). The effects of school context are also considered. Results show that African American and Native American adolescents experience greater social costs with academic success than Whites. Pertaining to school context, findings suggest that the differential social consequences of achievement experienced by African Americans are greatest in more highly achieving schools, but only when these schools have a smaller percentage of Black students. Students from Mexican descent also showed differential social costs with achievement in particular contexts. The implications of these findings to theory, policy, and future research are discussed.
