Associations Between Cumulative Risk, Childhood Sleep Duration, And Body Mass Index Across Childhood, Tiffany Phu, Jenalee R. Doom

Psychology: Faculty Scholarship

Background: Although associations between cumulative risk, sleep, and overweight/obesity have been demonstrated, few studies have examined relationships between these constructs longitudinally across childhood. This study investigated how cumulative risk and sleep duration are related to current and later child overweight/obesity in families across the United States sampled for high sociodemographic risk.

Methods: We conducted secondary analyses on 3690 families with recorded child height and weight within the Fragile Families and Child Well-Being Study. A cumulative risk composite (using nine variables indicating household/ environmental, family, and sociodemographic risk) was calculated for each participant from ages 3-9 years. Path analyses …

Preconception Maternal Posttraumatic Stress And Child Negative Affectivity: Prospectively Evaluating The Intergenerational Impact Of Trauma, Danielle A. Swales, Elysia Poggi Davis, Nicole E. Mahrer, Christine M. Guardino, Madeleine Shalowitz, Sharon L. Ramey, Christine Dunkel Schetter

Psychology: Faculty Scholarship

The developmental origins of psychopathology begin before birth and perhaps even prior to conception. Understanding the intergenerational transmission of psychopathological risk is critical to identify sensitive windows for prevention and early intervention. Prior research demonstrates that maternal trauma history, typically assessed retrospectively, has adverse consequences for child socioemotional development. However, very few prospective studies of preconception trauma exist, and the role of preconception symptoms of posttraumatic stress disorder (PTSD) remains unknown. The current study prospectively evaluates whether maternal preconception PTSD symptoms predict early childhood negative affectivity, a key dimension of temperament and predictor of later psychopathology. One hundred and eighteen …

Timing Of Childhood Adversities And Self-Injurious Thoughts And Behaviors In Adolescence, Samantha J. North, Kathryn R. Fox, Jenalee R. Doom

Graduate School of Professional Psychology: Faculty Scholarship

Greater childhood adversity predicts a higher likelihood of later self-injurious thoughts and behaviors (SITB). There is little research focused on whether the timing of childhood adversity predicts SITB. The current research examined whether the timing of childhood adversity predicted parent- and youth-reported SITB at age 12 and 16 years in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) cohort (n = 970). We found that greater adversity at age 11–12 years consistently predicted SITB at age 12 years, while greater adversity at age 13–14 years consistently predicted SITB at age 16 years. These findings suggest there may be sensitive …

Parental Buffering In The Context Of Poverty: Positive Parenting Behaviors Differentiate Young Children's Stress Reactivity Profiles, Samantha M. Brown, Lisa J. Schlueter, Eliana Hurwich-Reiss, Julia Dmitrieva, Elly Miles, Sarah Enos Watamura

Psychology: Faculty Scholarship

Experiencing poverty increases vulnerability for dysregulated hypothalamic–pituitary–adrenal (HPA) axis functioning and compromises long-term health. Positive parenting buffers children from HPA axis reactivity, yet this has primarily been documented among families not experiencing poverty. We tested the theorized power of positive parenting in 124 parent–child dyads recruited from Early Head Start (Mage = 25.21 months) by examining child cortisol trajectories using five samples collected across a standardized stress paradigm. Piecewise latent growth models revealed that positive parenting buffered children's stress responses when controlling for time of day, last stress task completed, and demographics. Positive parenting also interacted with income such that …

Child Abuse And Revictimization: Improving Models Of Revictimization Risk, Julie M. Olomi

Electronic Theses and Dissertations

Child abuse (CA) puts women at risk for later victimization by a different perpetrator, referred to as revictimization (RV); however, how this risk is conveyed is not well understood. CA is associated with a diverse set of negative sequelae (e.g., posttraumatic symptomology, emotion regulation difficulties), many of which could plausibly affect risk for RV. To date, most empirical studies of RV have mainly compared groups of women with and without abuse and RV histories using variablecentered approaches. This approach has led to a focus on differences between abused and non-abused women on a few CA-related variables tested at a time. …

Neural Processing Of Infant And Adult Face Emotion And Maternal Exposure To Childhood Maltreatment, Aviva K. Olsavsky, Joel Stoddard, Andrew Erhart, Rebekah C. Tribble, Pilyoung Kim

Psychology: Faculty Scholarship

Face processing in mothers is linked to mother–infant social communication, which is critical for parenting and in turn for child development. Neuroimaging studies of child maltreatment-exposed (CME) mothers are sparse compared to studies of mothers with postpartum depression, which have suggested blunted amygdala reactivity to infant stimuli. We expected to see a similar pattern in CME mothers. Based on broader studies in trauma-exposed populations, we anticipated increased amygdala reactivity to negative adult face stimuli in a comparison task in CME mothers given heightened evaluation of potential threat. We examined Neuroimaging studies of mothers with childhood maltreatment exposure (CME) (18–37 years …
