Plasma BDNF is reduced among middle-aged and elderly women with impaired insulin function: Evidence of a compensatory mechanism

Brain-derived neurotrophic factor (BDNF) plays a regulatory role in neuronal differentiation and synaptic plasticity and has been linked to glucose regulation and cognition. Associations among plasma BDNF, cognition, and insulin function were explored. Forty-one participants with impaired insulin function (IIF), ranging from insulin resistance to type 2 diabetes mellitus (T2DM), were matched with 41 healthy controls on gender, age, education, and IQ. Participants received complete medical, neurological, psychiatric, and neuropsychological evaluations. IIF individuals had significantly lower plasma BDNF levels than controls, particularly females, and higher BDNF levels were associated with poorer explicit memory in IIF females, suggesting that higher levels within this group may reflect the body’s efforts to respond to damage. After accounting for age, education, and HbA1c, BDNF significantly predicted 13.1–23.5% of the variance in explicit memory in IIF women. These findings suggest that BDNF elevations within diseased groups may not always be a marker of health.     

Embodied Discrimination: The Relation of Sexism and Distress to Women’s Drinking and Smoking Behaviors

Discrimination has been conceptualized as a stressor that may be more negative than generic stress because it is tied to valued and unchangeable social identities. As with other stressful events, the experience of sexism has been related to poorer mental health and some physical health outcomes. This study of 179 female college students (79% of whom were White) showed that the relation between perceived sexism and binge drinking and smoking was mediated by psychological distress. In addition, there was a direct relation between sexism and smoking for weight control. Given the large toll that tobacco and excessive alcohol use exact on the U.S. population, we suggest that policy makers aim to reduce discrimination as one method to improve overall health.     

Gender Differences in Spiritual Development During the College Years

Gender differences in spirituality and related traits are an assumed reality despite the lack of empirical information that directly compares women and men. I used a national and longitudinal sample of 3,680 college students surveyed with the Cooperative Institutional Research Program (CIRP) Freshman Survey (2000) and later with the College Students’ Beliefs and Values (CSBV) Survey (2003) to examine gender differences on 13 spiritual characteristics and explore the personal and educational factors associated with changes in spirituality during college. The results showed marked gender differences in spiritual qualities, and gendered patterns of spiritual development were identified that are associated with religious identity, peer relationships, and science exposure.     

The use of background and ability profiles to predict college student outcomes

To determine whether profiles of predictor variables provide incremental prediction of college student outcomes, the authors 1st applied an empirical clustering method to profiles based on the scores of 2,771 entering college students on a battery of biographical data and situational judgment measures, along with SAT and American College Test scores and high school grade point average, which resulted in 5 student groups. Performance of the students in these clusters was meaningfully different on a set of external variables, including college grade point average, self-rated performance, class absenteeism, organizational citizenship behavior, intent to quit their university, and satisfaction with college. The 14 variables in the profile were all significantly correlated with 1 or more of the outcome measures; however, nonlinear prediction of these outcomes on the basis of cluster membership did not add incrementally to a linear-regression-based combination of these 14 variables as predictors.     

Black and White women's perspectives on femininity

The authors explore how Black and White women view three aspects of normative femininity, and whether self-rated femininity is related to feminism. Through telephone surveys, a nationally representative sample of women (N=1130) rated themselves on feminism and items derived from Collins' (2004) benchmarks of femininity: feminine appearance, traits, and traditional gender role ideology. Confirmatory factor analysis revealed both groups conceptualized femininity as including the same dimensions, although Black women rated themselves higher on items related to feminine appearance. Among White women, traditional gender ideology was negatively related to feminism; among Black women, wearing feminine clothes was positively related to feminism. Results are discussed in terms of possibilities for resistance to the hegemonic concept of femininity that both groups share.     

A cognitive-emotional model of NSSI: using emotion regulation and cognitive processes to explain why people self-injure

Non-suicidal self-injury (NSSI) is a complex behaviour, routinely engaged for emotion regulatory purposes. As such, a number of theoretical accounts regarding the aetiology and maintenance of NSSI are grounded in models of emotion regulation; the role that cognition plays in the behaviour is less well known. In this paper, we summarise four models of emotion regulation that have repeatedly been related to NSSI and identify the core components across them. We then draw on social cognitive theory to unite models of cognition and models of emotion in developing a new cognitive-emotional model of NSSI. Our model articulates how emotion regulation and cognition can work in concert to govern NSSI, and offers several new research questions that can be addressed within this framework.     

Early executive control and risk for overweight and obesity in elementary school

An emerging literature suggests that poor executive control (EC) may be associated with clinical weight problems, e.g., body mass index (BMI) for age percentile ≥85 in children. However, our understanding of the impact of EC on overweight and obesity in childhood is limited by the lack of longitudinal studies spanning critical developmental periods and assessing EC using comprehensive performance-based batteries. The current study addresses these limitations in a longitudinal examination of 212 children who completed an extensive laboratory-based EC task battery in preschool (age 4 years and 6 months) and were followed through elementary school (Grades 1 through 4) with objective measures of weight status. The logistic regression results indicate that poorer EC in preschool is associated with significantly greater risk for clinical weight problems (either overweight or obese status, as defined by BMI-for-age percentile ≥ 85) in elementary school, controlling for maternal education. EC in preschool was not significantly associated with risk for obese status, specifically (defined by BMI-for-age percentile ≥ 95), but the trend was in the expected direction. The results suggest that early executive abilities are relevant for children’s subsequent health status, with deficits in EC in the critical period of preschool conferring risk for later problems with weight. Based on these findings, early interventions to promote stronger EC may be a promising, yet currently overlooked, component in pediatric obesity prevention efforts.     

Examination of a Multi‐Element Intervention on College Students' Electricity Consumption in On‐Campus Housing

Use of electricity is a significant contributor to climate change. Results from several studies have demonstrated short‐term success but long‐term success is rarely assessed, and weather is rarely measured despite its effects on energy use. We evaluated the long‐term effects of a multi‐element intervention package including visual prompts, feedback, and incentives on energy usage in two sorority houses over two years (four semesters) using a multiple baseline with reversal design while also accounting for weather fluctuations over that time period. Although daily graphs suggested intervention houses reduced their relative energy use compared to baseline, functional control over behavior was not established because reductions in energy consumption were observed approximately halfway through baseline, due possibly to reactivity; control houses showed no such pattern. Moreover, bubble graphs accounting for weather suggested an increase in energy use for the intervention house during Semester 1. We discuss the limitations of this study, suggestions for future research, and use of innovative methods of graphing energy use to better understand usage patterns and account for weather fluctuations.

Reactive vs. proactive antisocial behavior: differential correlates of child ADHD symptoms?

This study examines the relation between proactive and reactive antisocial behavior with Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms. Caregivers of children aged 8 to 15 (n = 84) being evaluated at a child psychiatry outpatient clinic served as participants. Given the conceptual similarity between reactive antisocial behavior (ASB) and particular ADHD symptoms, we hypothesized that ADHD symptoms would be more closely related to reactive than to proactive ASB. Based on peer deviancy training models of ASB, we also hypothesized that the relation between ADHD symptoms and proactive ASB would increase from middle childhood to adolescence. Both hypotheses were supported. These findings suggest that reactive ASB is relatively specific to ADHD symptoms, and that intervening before early adolescence may be critical to prevent the onset of comorbid proactive ASB.     

Pure Versus Co-occurring Externalizing and Internalizing Symptoms in Children: The Potential Role of Socio-Developmental Milestones

Co-occurring internalizing and externalizing disorders are moderately prevalent in children, adolescents, and adults (Anderson, Williams, McGee, & Silva, 1987; McConaughy & Skiba, 1994), but much remains to be understood regarding why some children show “pure” versus co-occurring internalizing and externalizing symptoms. One possible influence that has previously not been considered is the failure to attain socio-developmental milestones, which paradoxically may prevent the development of co-occurring symptoms for some children. The present study proposes a model in which failure to attain relevant socio-developmental milestones might explain why some children may not develop heterotypic co-occurring symptoms. Specifically, it is proposed that specific clusters of internalizing symptoms (i.e., high social anxiety, withdrawal, and inhibition) and externalizing symptoms (i.e., high impulsivity, hyperactivity, and emotional reactivity) may be associated with the failure to attain socio-developmental milestones (i.e., poor peer relations for anxious children, lack of self-reflection and evaluation for impulsive/reactive children) that, in turn, may prevent subgroups of children from developing co-occurring, heterotypic symptoms.
