Individual Longitudinal Changes In Dna-Methylome Identify Signatures Of Early-Life Adversity And Correlate With Later Outcome, Annabel K. Short, Ryan Weber, Noriko Kamei, Christina Wilcox Thai, Hina Arora, Ali Mortazavi, Hal S. Stern, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

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 …

A Predictable Home Environment May Protect Child Mental Health During The Covid-19 Pandemic, Laura M. Glynn, Elyssia Poggi Davis, Joan L. Luby, Tallie Z. Baram, Curt A. Sandman

Psychology Faculty Articles and Research

Objective

Information about the adverse effects of the COVID-19 pandemic on adolescent and adult mental health is growing, yet the impacts on preschool children are only emerging. Importantly, environmental factors that augment or protect from the multidimensional and stressful influences of the pandemic on emotional development of young children are poorly understood.

Methods

Depressive symptoms in 169 preschool children (mean age 4.1 years) were assessed with the Preschool Feelings Checklist during a state-wide stay-at-home order in Southern California. Mothers (46% Latinx) also reported on externalizing behaviors with the Strengths & Difficulties Questionnaire. To assess the role of environmental factors in …

Stress And Negative Affect As Mediators In The Association Between Parental Social Support And Lung Function In Adolescents With Asthma, Amber Osorno, Eric Sternlicht, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Zeev N. Kain, Brooke Jenkins

SURF Posters and Papers

Asthma is the leading chronic condition amongst children in the United States as 7.5% of children are diagnosed with asthma. Studies have shown that positive social support is associated with positive asthma management. A strong social support system predicts good management of asthma symptoms; however, current literature has not yet examined how social support impacts lung function as opposed to merely symptom management. Stress and negative affect have been revealed to be associated with worse asthma control, as well as exacerbation of symptoms. Stressful situations, such as the death of a family member, unemployment, and familial tensions lead to worsening …

Efficacy Of Mindfulness On Stress And Anxiety In Adolescents: A Systematic Review, Callimarie Bell

Psychology Capstone Projects

Most mental health problems begin early in life, with 50% of all problems beginning by the age of 14. Thus, adolescents are a vulnerable population and factors impacting their mental health should be examined. One factor is stress. Stress has been linked to both mental and physical health problems, depression, and anxiety. Anxiety disorders are the most prevalent mental health problem among adolescents. A potential treatment is that of mindfulness. Mindfulness originated from Buddhism and is the non-judgmental acceptance of thought, feelings, and experiences. Mindfulness has been found to reduce symptoms of stress and anxiety, alleviate chronic pain, and reduce …

Executive Control In Hispanic Children: Considering Linguistic And Sociocultural Factors, Miriam M. Martinez

Department of Psychology: Dissertations, Theses, and Student Research

Executive control represents a collection of high-order cognitive processes that are associated with important child outcomes, including academic achievement and social competencies. Despite the burgeoning interest in examining the development of executive control, less is known about the development of these skills among ethnic minority children. Hispanic children are currently the largest ethnic minority group in the United States and their diverse sociocultural and linguistic backgrounds provide an excellent context to study the influence of linguistic and sociocultural factors on the development of child executive control. The purpose of the three complementary studies reported in this dissertation is to contribute …

Parental Efficacy, Experience Of Stressful Life Events, And Child Externalizing Behavior As Predictors Of Filipino Mothers' And Fathers' Parental Hostility And Aggression., Aileen S. Garcia, Liane Peña Alampay

Psychology Department Faculty Publications

This study assessed relations of parental efficacy, experience of stressful life events, and child externalizing behavior to Filipino mothers and fathers’ parental hostility and aggression. Orally-administered surveys were conducted with 117 mothers and 98 fathers for the first year of data collection, and again a year later with 107 mothers and 83 fathers. Path analyses showed that mothers’ report of child externalizing behavior predicted subsequent parental hostility and aggression. For fathers, child externalizing behavior and experience of stressful life events predicted parental hostility and aggression. Additionally, fathers’ parental efficacy was found to moderate the relationship between experience of stressful life …

Prenatal Maternal Stress Programs Infant Stress Regulation, Elyssia Poggi Davis, Laura M. Glynn, Feizal Waffarn, Curt A. Sandman

Psychology Faculty Articles and Research

Objective: Prenatal exposure to inappropriate levels of glucocorticoids (GCs) and maternal stress are putative mechanisms for the fetal programming of later health outcomes. The current investigation examined the influence of prenatal maternal cortisol and maternal psychosocial stress on infant physiological and behavioral responses to stress.

Methods: The study sample comprised 116 women and their full term infants. Maternal plasma cortisol and report of stress, anxiety and depression were assessed at 15, 19, 25, 31 and 36 + weeks' gestational age. Infant cortisol and behavioral responses to the painful stress of a heel-stick blood draw were evaluated at 24 hours after …

Stress Levels And Development: A Phenomenology Of Autistic Children And Their Parents, Tiffany R. Wiggs

Senior Honors Theses

Being a parent means taking on both the joys and struggles that come with it. When a parent discovers that his or her child has been diagnosed with autism spectrum disorder (ASD), the level of stress changes. It could be helpful to discover the severity of change that the stresses involved in parenting a child with ASD brings to the parent/child relationship and what effect this has on a child’s physical, cognitive, emotional, and spiritual development. To attempt to answer these questions, six parents were interviewed. Findings suggested that structure in daily living improves the quality of the child/parent relationship …
