Allostatic Load in Childhood, Adolescence, and Young Adulthood: Are Assumptions of Measurement Invariance Warranted?

OVERVIEW: Allostatic load represents the cumulative toll of chronic mobilization of the body's stress response systems, as indexed by biomarkers. Higher levels of stress and disadvantage predict higher levels of allostatic load, which, in turn, predict poorer physical and mental health outcomes. To maximize the efficacy of prevention efforts, screening for stress- and disadvantage-associated health conditions must occur before middle age-that is, during childhood, adolescence, and young adulthood. However, this requires that models of allostatic load display properties of measurement invariance across age groups. Because most research on allostatic load has featured older adults, it is unclear if these requirements can be met. METHODS: To address this question, we fit a series of exploratory and confirmatory analytic models to data on eight biomarkers using a nationally representative sample of N = 4260 children, adolescents, and young adults drawn from the National Health and Nutrition Examination Survey dataset. RESULTS: Exploratory and confirmatory models indicated that, consistent with allostatic load theory, a unidimensional model was a good fit to the data. However, this model did not display properties of measurement invariance; post-hoc analyses suggested that the biomarkers included in the final confirmatory model were most strongly intercorrelated among young adults and most weakly intercorrelated among adolescents. CONCLUSIONS: These results underscore the importance of testing assumptions about measurement invariance in allostatic load before drawing substantive conclusions about stress, disadvantage, and health by directly comparing levels of allostatic load across different stages of development, while underscoring the need to expand investigations of measurement invariance to samples of longitudinal data.

Black Young Adult Superwomen in the Face of Gendered Racial Microaggressions: Contextualizing Challenges With Acceptance and Avoidance and Emotional Eating.

BACKGROUND: Black young adult women (ages 18-35) are at disproportionate risk for obesity and emotional eating. Emotional eating interventions target psychological flexibility, such as reducing experiential avoidance and increasing acceptance of food-related thoughts. Yet Black women face gendered racism, and some endorse roles that reduce psychological flexibility, such as the superwoman schema role. Culturally centered stress and coping has often been overlooked, leading to an incomplete understanding of processes that engender emotional eating and the implications for appropriate and effective interventions for Black young adult women. PURPOSE: We investigated direct and indirect pathways of associations between stress from gendered racial microaggressions to emotional eating through the endorsement of superwoman schema and two aspects of psychological flexibility. METHODS: Black young adult women (N = 504; Mage = 24.72; 75.2% African American; 98.4% cisgender) participated in an online survey wherein they reported demographics, stress from gendered racial microaggressions, superwoman schema, experiential avoidance, acceptance of food-related thoughts, and emotional eating. Path analysis was conducted to examine direct and indirect effects. RESULTS: Results provided evidence for indirect associations between more stress from gendered racial microaggressions and more emotional eating. More stress was associated with greater endorsement of the superwoman schema which was associated with more experiential avoidance and less acceptance of food-related thoughts, which were each associated with more emotional eating. CONCLUSIONS: Endorsement of superwoman schema and concomitant avoidance and less acceptance may be one way that gendered racial stress propels emotional eating. Future research could test intervention components that disrupt this path.

Emotional eating is eating in order to alleviate negative emotions, like those from stress. Black young adult women face particular forms of stress from being mistreated at the intersection of their race and gender. This research was needed to better understand processes that engender emotional eating for Black young adult women so that appropriate and effective interventions can be developed for this group. In this correlational study, Black young adult women (ages 18­35) completed an online survey wherein they answered questions about their experiences, thoughts, and behaviors. The study results indicated that stress from mistreatment due to being a Black woman was associated with endorsing a need to be strong. This need to be strong was associated with avoiding experiences that may lead to negative emotional states and being less accepting of distressing thoughts about food. More avoidance and less acceptance were each associated with more emotional eating. Therefore, if emotional eating or obesity-related interventions already target acceptance and avoidance, but do not reference or contextualize them for Black young adult women­particularly in terms of stress from mistreatment as a Black woman and the need to be strong­such interventions may be less effective.

Same Goals, but Different Outcomes: Present-Focused versus Future-Focused Memory Beliefs Differentially Predict Young and Older Adults' Everyday Use of Memory Strategies.

OBJECTIVE: We investigated whether beliefs about the current versus future effectiveness of memory strategies predict young and older adults' everyday strategy use. METHOD: 103 young and 91 older adults reported their memory goals, beliefs about the current and future effectiveness of various strategies, and frequency of use of each strategy type. RESULTS: The two age groups equally valued current and future memory. Young adults' strategy selection related only to their beliefs about the strategies' current effectiveness; older adults utilized approaches they perceived as effective for improving both future and current memory. IMPLICATIONS: Findings highlight the importance of the temporal nature of memory strategy beliefs.

Mother knows best or does she? Perceptions of the memory abilities of pediatric patients with epilepsy as reported by patients and their parents across time.

PURPOSE: This study compared the self-reported and parent-reported memory of children with epilepsy across time and explored the relationships between these measures of subjective memory and the children's actual performance on objective neuropsychological tests. METHOD: One-hundred and nineteen children with epilepsy who were surgical candidates underwent comprehensive neuropsychological testing that included the Everyday Verbal Memory Questionnaire (EVMQ). Each child's parent and 82 of the children themselves completed the appropriate version of this subjective memory measure. After 9 months, the children returned for a second neuropsychological evaluation with 71 parents and 39 children completing the same questionnaire. Approximately one-third of the children in the study underwent surgery between the two evaluations. Standardized regression-based norms were used to quantify change in cognitive abilities across assessments. RESULTS: Results revealed significant relationships between parent reports and child reports of the children's memory abilities. Parent reports, but not child reports, correlated with the children's objective test scores at baseline. In contrast, children were more attuned to changes in their memory across time. CONCLUSIONS: These findings demonstrate the importance of considering both parent and child perceptions of everyday cognitive functioning when evaluating cognition and cognitive changes over time in pediatric patients with epilepsy.
