Childhood maltreatment exposure and physical functional limitations in late adulthood: examining subjective sleep quality in midlife as a mediator.

Objective: The present study had three major aims: 1) To identify sub-groups of adults with differing combinations of childhood maltreatment exposures, 2) to understand the association of childhood maltreatment sub-group membership with subjective sleep quality in midlife, and 3) to assess poor sleep quality in midlife as a mechanism between childhood maltreatment sub-group membership and physical functional limitations in late adulthood. Design: Data come from the Biomarker project of the Midlife Development in the United States study (n = 1251). Outcome measures: The Pittsburgh Sleep Quality Index (Buysse et al., 1989) was used to assess sleep quality in midlife. Functional limitations in late adulthood were measured using a version of the SF-36 (Brazier et al., 1992). Results: Two vulnerable childhood maltreatment sub-groups emerged (Physical and Emotional Maltreatment Sub-group, n = 49, and Sexual Abuse Sub-group, n = 105) and a normative sub-group (n = 1087; low exposure to childhood maltreatment). Poor sleep quality in midlife mediated the association between both maltreatment sub-groups and functional limitations in late adulthood. Conclusion: Results highlight the role of sleep in linking childhood maltreatment with functional impairments in adulthood and offer a potential target for interventions to improve quality of life in older adults.

Developmental antecedents of adolescent optimism in rural midwestern U.S. Latinx youth.

AIMS: Decades of scientific research have found optimism to have wide-ranging effects on individuals' health and well-being. Researchers have largely examined optimism in adults, but have begun addressing the benefits of optimism in adolescents. Challenges and stressors in adolescence can threaten youths' subjective well-being; therefore, identifying factors that contribute to the growth of optimism could have important health implications. However, researchers have more often examined the effect of optimism on youth outcomes rather than factors that might positively or negatively contribute to the development of optimism. METHODS: We assessed how salient developmental tasks (resilience, ethnic pride, and school attachment), family stress, and depressive problems individually contribute to Latinx youths' optimism at two time points (N = 123, 58.8% female, M age = 11.54 years). RESULTS: We found support for associations between both resilience and school attachment and optimism, but findings were weaker across time and with stressors included in the model. Depressive problems also appeared to weaken optimism across time. CONCLUSION: Given the established links between optimism and health, it will be important for researchers to continue to identify factors that contribute to the development of youth optimism, and assess whether they could be used in interventions to foster optimism.

Associations between Effortful Control, Cortisol Awakening Response, and Depressive Problems in Latino Preadolescents.

The present study examined associations between effortful control, a trait marker of self-regulation, adaptive HPA system functioning (as reflected by the CAR), and concurrent and longitudinal depressive problems, in a sample of preadolescent Latino youth (N = 119, mean age = 11.53 years, 59% female). We hypothesized that trait readiness for self-regulation (e.g., effortful control) could be related to physiological state readiness for self-regulation (e.g., CAR), and that both may counter depressive problems. We found that youth's CAR was positively associated with effortful control, and negatively with youth depressive problems. Effortful control and youth depressive problems were also negatively associated. Longitudinal relations of CAR and effortful control on depressive problems at T2 were not significant in the structural equation model after controlling for T1 depressive problems, although these variables were significant in the bivariate correlations. Results suggest that both trait-regulation and physiological regulation may counter depressive problems in Latino youth.

Parental restrictive feeding with Latinx adolescents: Examining the role of adolescent effortful control.

The objective of this study was to test if youth effortful control, a general process of self-regulation that is rooted in temperament, uniquely predicts maternal restrictive feeding with Latinx adolescents above and beyond demographic/contextual factors, prior use of restrictive feeding, and common markers of obesity-proneness. The study sample consisted of Latinx fifth and sixth graders and their mothers residing in the Midwestern U.S. (N =  97 dyads). Effortful control, maternal restrictive feeding, demographic/contextual factors, and markers of obesity proneness were measured across two waves of data collection approximately one year apart. Results demonstrated an inverse relation between effortful control and maternal restrictive feeding after controlling for Time 1 demographic/contextual factors, maternal BMI, maternal restrictive feeding, youth BMI z-score, and perceived youth weight. Future directions include testing for the presence of an ironic feedback process such that Latinx mothers' attempts to overcome deficits in their children's self-regulation skills through restrictive feeding may be inadvertently maintaining the problem.

Project SWEAT (Summer Weight and Environmental Assessment Trial): study protocol of an observational study using a multistate, prospective design that examines the weight gain trajectory among a racially and ethnically diverse convenience sample of economically disadvantaged school-age children.

INTRODUCTION: Racial/ethnic minority school-age children are at risk for unhealthy weight gain during the summer, and there is a dearth of information regarding the underlying behavioural and environmental factors. The study objective is to provide an in-depth examination of dietary and physical activity behaviours and food, physical activity, and social environments of African American and Hispanic school-age children during the summer. METHODS AND ANALYSIS: An observational study will be conducted using a multistate (Ohio and Indiana, USA) prospective design examining the weight gain trajectory among a racially/ethnically diverse convenience sample of economically disadvantaged school-age children. In addition, a subset of these children will be evaluated to learn their daily health behaviours and food, physical activity, and social environments during the summer. Comparisons will be made between children who routinely attend programming and those who do not, both in the larger sample and subset. Determinants of programme participation and factors that may enhance the beneficial effects of programme participation will also be identified. Data collection at the Indiana site is planned for summer 2018. ETHICS AND DISSEMINATION: This study is approved by The Ohio State University Behavioral and Social Sciences Institutional Review Board. Results from this study will be disseminated in publications for practitioners, scientists and stakeholders. TRIAL REGISTRATION NUMBER: NCT03010644; Pre-results.

Interpersonal Problems and Their Relationship to Depression, Self-Esteem, and Malignant Self-Regard.

DSM-5 Section III recommends that level of personality functioning be assessed. This requires an assessment of self and other representations. Malignant self-regard (MSR) is a way of assessing the level of functioning of those with a masochistic, self-defeating, depressive, or vulnerably narcissistic personality. In Study 1, 840 undergraduates were assessed for MSR, depressive symptoms, self-esteem, anaclitic and introjective depression, and interpersonal problems. MSR, self-esteem, depressive symptoms, and anaclitic and introjective depression were correlated with multiple dimensions of interpersonal problems, and MSR predicted the most variance in interpersonal scales measuring social inhibition, nonassertion, over-accommodation, and excessive self-sacrifice. MSR, anaclitic, and introjective depression predicted unique variance in six of the eight domains of interpersonal problems assessed. In Study 2, 68 undergraduates were provided positive or negative feedback. Consistent with theory, MSR predicted unique variance in state anxiety but not state anger. Results support the validity of the MSR construct.

Expanding the utility of the malignant self-regard construct.

The empirical and theoretical literature suggest that several proposed personality disorders (PDs) - Masochistic/Self-Defeating, Depressive, and Vulnerably Narcissistic - may be related through a common self-representation know as Malignant Self-Regard (MSR). To assess this construct, the MSR Questionnaire (MSRQ) was developed. Though its initial psychometric properties were very strong, the present study extended these findings by examining the relationship of the MSRQ with measures of other PDs and depressive subtypes, and by establishing four-week and eight-week test-retest reliability in two samples (Ns=840, 911) of undergraduate students. The MSRQ was internally consistent and temporally stable over four and eight weeks. It was positively correlated with measures of introjective and anaclitic depression, measures of Self-Defeating, Depressive, and Vulnerably Narcissistic personalities (rs ranging between 0.60 and 0.82), and other select PDs. After controlling for depressive symptoms and self-esteem, the highest remaining partial correlations were with Vulnerably Narcissistic, Self-Defeating, Depressive, and Avoidant personalities. A factor analysis of the MSRQ with measures of other PDs yielded a two-factor solution, with MSR loading most strongly on one factor, along with Vulnerably Narcissistic, Avoidant, Depressive, and Self-Defeating personalities. It is concluded that MSR is a psychometrically supported construct that might have good clinical utility in explaining personality pathology that has historically been difficult to assess.
