Patterns And Predictors Of Stability And Change In Representations Of Romantic Relationships In Adolescence And Young Adulthood, Claire Stephenson Flansburg

Electronic Theses and Dissertations

Research on the stability of attachment representations across the lifespan has led to two alternative perspectives: the prototype and revisionist perspectives (Fraley, 2002). The prototype perspective posits that there is a stable factor underlying fluctuations in representations and the revisionist perspective argues that there is no inherently stable factor. The current study employed a latent trait-state model to investigate these alternative models of stability and change in representations of romantic relationships in adolescence and young adulthood. The study also sought to identify individual characteristics and relationship experiences that are associated with changes in representations. In a sample of 200 participants, …

Risk For Engagement In Nonsuicidal Self-Injury In Children And Adolescents, Andrea Lee Barrocas Gottlieb

Electronic Theses and Dissertations

Although NSSI engagement is a growing public health concern, little research has documented the developmental precursors to NSSI in longitudinal studies using youth samples. This study aimed to expand upon previous research on groups of NSSI engagement in a population-based sample of youth using multi-wave data. Moreover, this study examined whether chronic peer and romantic stress, the serotonin transporter gene (5-HTTLPR), parenting behaviors, and negative attributional style predicted the NSSI group membership as well as the role of sex and grade. Participants were 549 youth in beginning in the 3^rd, 6^th, and 9^th grades at …

Examining The Relationship Among Genes, Attention Bias To Emotion, Depression In Youth, Jessica L. Jenness

Electronic Theses and Dissertations

The investigation of biologically initiated pathways to psychological disorder is critical to advance our understanding of mental illness. Research has suggested that attention bias to emotion may be an intermediate trait for depression associated with biologically plausible candidate genes, such as the serotonin transporter (5-HTTLPR) and catechol-o-methyl-transferase (COMT) genes, yet there have been mixed findings in regards to the precise direction of effects. The experience of recent stressful life events (SLEs) may be an important, yet currently unstudied, moderator of the relationship between genes and attention bias as SLEs have been associated with both gene expression and attention to emotion. …

The Role Of Passage Topic Knowledge In Typical And Poor Comprehenders' Recall, Chelsea E. Meenan

Electronic Theses and Dissertations

This dissertation examines the role of topic knowledge (TK) in comprehension among typical readers and those with Specifically Poor Comprehension (SPC), i.e., those who demonstrate deficits in understanding what they read despite adequate decoding. Previous studies of poor comprehension have focused on weaknesses in specific skills, such as word decoding and inferencing ability, but this dissertation examined a different factor: whether deficits in availability and use of TK underlie poor comprehension. It is well known that TK tends to facilitate comprehension among typical readers, but its interaction with working memory and word decoding is unclear, particularly among participants with deficits …

Examining The Complex Relationships Of Early Intervention On Language And Psychosocial Development In Families Facing Multiple Risks With A Focus On Children Of Hispanic Immigrants, Marina Marie Mendoza

Electronic Theses and Dissertations

Abundant research has shown that poverty has negative influences on young child academic and psychosocial development, and unfortunately, disparities in school readiness between low and high income children can be seen as early the first year of life. The largest federal early care and education intervention for these vulnerable children is Early Head Start (EHS). To diminish these disparate child outcomes, EHS seeks to provide community based flexible programming for infants and toddlers and their families. Given how relatively recent these programs have been offered, little is known about the nuances of how EHS impacts infant and toddler language and …

The Impact Of Prefrontal Cortex "Warm Up" On Immediate Cognitive Reappraisal Ability In Older Adolescents With Elevated Symptoms Of Depression, Emma L. Peterson

Electronic Theses and Dissertations

Cognitive Reappraisal (CR) is a central component of Cognitive Behavioral Therapy for adolescent depression. Yet, previous research indicates that a brain region highly associated with successful CR in adults, the Prefrontal Cortex (PFC), is not fully developed until early adulthood. Thus, there is growing concern that CBT interventions directed at building CR abilities in depressed teens might be constrained by PFC immaturity. However, CR is an effective strategy for regulating affect. The current study evaluated an intervention aimed at enhancing CR performance through PFC “warm up” with a working memory task. Additionally, the study examined moderators of intervention response, as …

The Caregiver–Child Relationship, Youth Mental Health, And Placement Stability In A Child Welfare Sample, Laura A. Rindlaub

Electronic Theses and Dissertations

Objective: Healthy relationships between adolescents and their caregivers have been robustly associated with better youth outcomes in a variety of domains. Youth in contact with the child welfare system are at higher risk for worse outcomes including mental health problems and home placement instability. A growing body of literature points to youth mental health problems as both a predictor and a consequence of home placement instability in this population; the present study aimed to expand our understanding of these phenomena by examining the interplay among the caregiver-child relationship, youth mental health symptoms, and placement change over time. Method: The sample …

Internet Delivery Of Prep-Based Relationship Education For Older Couples, Benjamin A. Loew

Electronic Theses and Dissertations

Healthy marriage has been associated with increased longevity and better health in later life. At the same time, many older couples will confront age-related stressors that may result in relationship distress, such as declining health, decisions about retirement, and caring for elderly parents and/or adult children. Yet empirical knowledge of relationship dynamics among older couples is limited, and there appears to have been little development, provision, or assessment of research-based relationship services for this population.

In the current study, 93 individuals representing 61 older-adult couples participated in a randomized, waitlist-controlled trial of an online version of the Prevention and Relationship …

Gender Differences In Risk Factors And Mechanisms For Adolescent Offending, Emma Venell Espel

Electronic Theses and Dissertations

From 1985 to 2009, the juvenile justice system processed 86% more offending cases for females, with only a 17% rise in male cases (Puzzanchera et al., 2012), highlighting the urgent need for understanding of gender differences in etiological factors of offending. Specifically, there is an essential need to understand mechanisms of the relationship between risk factors and offending behavior. The current work combines two studies with a gender-sensitive approach and an aim to investigate gender differences in a subset of modifiable mechanisms, such as anxiety and impulse control, which link interpersonal risk and offending. The first study tests gender differences …
