Investigating The Shared And Unique Mechanisms Of The Development Of Comorbid Eating Disorder-Anxiety Symptoms During Adolescence., Leigh Cara Brosof

Electronic Theses and Dissertations

Introduction: Eating disorders are associated with significant morbidity, psychiatric comorbidity, and impairment. Despite the detrimental outcomes associated with eating disorders, effective treatments for eating disorders are lacking. One factor that has impeded the identification of targets for intervention in eating disorders is the high comorbidity rate with other psychiatric disorders. Comorbidity models can inform treatments by showing which mechanisms are shared in comorbidity and which mechanisms are unique to specific disorders. Anxiety disorders are the most frequently co-occurring disorders with eating disorders, as 85% of individuals with eating disorders have a comorbid anxiety disorder. One mechanistic process in both anxiety …

Co-Rumination, Romantic Relationships, And Depressive Symptom Development In Adolescence, Jessica L. Shankman

Electronic Theses and Dissertations

The present research aimed to better understand the associations among romantic involvement, co-rumination with friends, and depressive symptom development in a sample of 338 adolescents (ages 14-19 years). Using a multi-method, longitudinal study design, the present study examined whether co-rumination (self-reported and observed) mediated the relationship between romantic involvement and depressive symptoms over time. Next, analyses separately tested whether this process was further moderated by positive friendship quality, whether youth discuss romantic experiences during problem talk with friends, and/or gender. Analyses also tested whether romantic relationship quality among romantically involved youth influenced depressive symptoms over time via co-rumination.

Early Adolescent Social Isolation, Hope, And Well-Being During A Pandemic, Alicen Hauck

Electronic Theses and Dissertations

Social isolation is often divided into two subcategories of objective and subjective. The COVID-19 pandemic has led to an increase in objective social isolation in the form of social distancing and fewer social events. Research delineating the relationship between social isolation and adolescent well-being utilize measures of subjective social isolation. Whereas, measures of objective social isolation are more commonly used with geriatric populations. Therefore, there is a lack of information specific to the impact of objective social isolation on adolescent well-being, particularly during a pandemic. The effects of social isolation due to COVID-19 will not be short lived. Deciphering the …

Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna

Electronic Theses and Dissertations

Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social …

Gender Differences In Co-Rumination Processes In The Friendships Of Late Adolescents: Relations To Depression Vulnerability, Helen J. Day

Electronic Theses and Dissertations

The primary aim of this study was to investigate gender differences in problem content and dyadic problem talk duration as potential contributors to previously documented depressogenic effects of co-rumination in late adolescence. Participants (N = 176 undergraduate students) included pairs of same-gender female (n = 37), same-gender male (n = 15), and cross-gender (n = 36) friends who completed self-report measures assessing individual depressive symptom severity, as well as within-dyad co-rumination habits and friendship quality. Dyads also participated in an observational problem talk task, which asked each dyad member to identify a current personal problem and discuss it with …

Ruminative Exploration In Late Adolescence And Its Relationship To Depression, Self-Esteem, And Parental Autonomy Support, Kelsey A. Redmayne

Electronic Theses and Dissertations

Ruminative exploration is considered a maladaptive dimension of identity development that appears to be at its highest during emerging adulthood (Luyckx, Klimstra, Duriez, Petergem, & Beyers, 2013a). Previous studies have assessed the relationship between ruminative exploration and well-being in populations in Dutch speaking populations of university students in Belgium (Luyckx, Gossens, & Soenens, 2006a; Luyckx, Gossens, Soenens, & Beyers, 2006b; Luyckx et al., 2007a; Luyckx et al., 2008; Luyckx et al., 2013a). Following the Dutch research, it was predicted that ruminative exploration will be positively correlated with symptoms of depression and low self-esteem among US college students. Beyond replicating the …

Development Of Cognitive Vulnerability For Depression In Youth: Sex, Emotional Maltreatment, And Depression Predict Negative Cognitive Style, Jessica R. Technow

Electronic Theses and Dissertations

Hopelessness theory is a prominent cognitive theory of depression that has been shown to predict depression in youth. However, research has yet to elucidate normative mean-level development of the cognitive risk factor in hopelessness theory from childhood through adolescence. The current study utilized a multi-wave design and hierarchical linear modeling (HLM) analyses to examine mean-level negative cognitive style growth and stability in late childhood, early adolescence, and mid-late adolescence. Participant sex, emotional maltreatment, and major depression were also tested as predictors of negative cognitive style. For three years, youth (N = 681, ages 7-18 at baseline) were assessed every 1.5 …

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …

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, …

A Study Of Suicide: A Latent Class-Evidence Based Model For Screening Of Suicidal Behaviors Among Adolescents Living In The United States From 1991-2011, Ryan Christopher Butterfield

Electronic Theses and Dissertations

The purpose of this study is to use self-reported data from adolescents as the foundation for a statistical screening process of suicidal behavior. Latent Class Analysis (LCA) is used to study patterns of suicidal behavior among adolescents and by extension, the development of evidence-based behavioral profiles of those adolescents identified as having suicidal-related behaviors. Suicidal behavior variables in the Youth Risk Behavior Survey (YRBS) ask about specific actions related to suicide ideation, planning, attempts and injury, but it is the underlying construct of "suicidal behavior" that is the ultimate question of interest. LCA allows for the development of evidence-based behavioral …

Trauma-Focused Involvement In Psychotherapy: Relations With Therapeutic Alliance And Symptoms Of Post-Traumatic Stress Disorder, Tess Siler Simpson

Electronic Theses and Dissertations

Childhood trauma is a risk factor for a wide range of psychopathology and other damaging outcomes later in life (Cohen, Mannarino, Murray, & Igleman, 2006; Saunders, 2003). Among the many treatment models developed for maltreated youth and their families, both specific and non-specific therapeutic factors such as developing a trauma narrative (e.g., trauma self-disclosure) and forming a strong therapeutic alliance have been identified as ―active ingredients‖ that contribute to positive treatment outcome (Cohen & Mannarino, 1996a, 1998a; Friedrich, 1990). The current study used data from the Aurora-Adolescent Mood Project, a community based randomized controlled trial, which evaluated the effectiveness of …

Longitudinal Interplay Of Dating Anxiety And Romantic Cognitions And Behaviors From Adolescence To Young Adulthood, Jessica K. Winkles

Electronic Theses and Dissertations

Dating is normative in adolescence and young adulthood, but can be disrupted and distressing to individuals experiencing dating anxiety. Cognitive-behavioral theories suggest dating anxiety impacts romantic cognitions and behaviors, and romantic cognitions and behaviors impact dating anxiety. Thus far, investigators have been unable to explore the interplay between dating anxiety and romantic cognitions and behaviors because studies are limited by cross-sectional designs. The present study examined longitudinal associations between two types of dating anxiety (dating interactions and active intentions for dating) and romantic appeal, jealousy, and compliance during conflict. Two hundred adolescents participated in the study, which began in the …

Examining The Alliance-Outcome Relationship: Reverse Causation, Third Variables, And Treatment Phase Artifacts, John Paul M. Reyes

Electronic Theses and Dissertations

Psychotherapy research reveals consistent associations between therapeutic alliance and treatment outcomes in the youth and adult literatures. Despite these consistent findings, prospective associations are not sufficient to support the claim that the alliance is a change mechanism in psychotherapy. The current study examined the direction of effect of the alliance-outcome relationship, the contribution of early symptom change in treatment to the development of therapeutic alliance, and the potential for pretreatment interpersonal functioning characteristics to be third variables that account for the association between alliance and outcome. Participants were adolescents with depression and a history of interpersonal trauma that presented to …

Development During Middle School: An Ecological-Transactional, Cross-Section Examination Of Early Adjustment, Rachel Susan White

Electronic Theses and Dissertations

This study utilized an ecological framework to investigate the types of variables that influence adolescent adjustment during middle school and how influences change or stay the same depending on grade level. A cross-sectional approach was taken in which students entering the beginning of their Sixth Grade year and students nearing the end of their Eighth Grade year were administered a comprehensive questionnaire including items about psychological adjustment, parenting characteristics, community support characteristics, ethnic identity, acculturation status, and socio-economic status. Findings suggest that Sixth and Eighth Graders’ experience of emotional and behavioral problems is influenced differently. This is particularly salient as …

Perceived Parental Characteristics And Neighborhood Support: How Do They Relate To Adolescents' Externalizing Behavior Problem, Rachel White

Electronic Theses and Dissertations

Externalizing behavior problems are related to many problematic outcomes for children and adolescents in their home, school, and community settings. Given the ramifications of difficulties related to externalizing behavior problems, the present study examines the relationships among adolescents' externalizing behavior problems, characteristics of adolescents' families, and their perceived neighborhood support in a sample of adolescents who are in the Sixth through Eighth Grades. As part of this study, adolescents were assessed one time in their school setting with a set of brief questionnaires. In particular, adolescents completed measures assessing their levels of externalizing behavior problems, characteristics of their families, their …

Peer And Maternal Relationship Predictors Of Adolescent Romantic Conflict Resolution, Pallavi Visvanathan

Electronic Theses and Dissertations

The objective of the current study was to examine whether change in adolescent conflict resolution in romantic relationships is predicted by adolescents' prior interactions with mothers and friends. A community sample of 191 adolescents (96 female), representative of the U.S. population, their mothers and close friends participated in this study. Data collection began when adolescents were in 10th grade (¬Average age = 15.9, SD = .52) and continued for the next five and a half years. Results indicated that teens engaged in positive problem solving, withdrawal, and compliance far more frequently than in aggressive conflict resolution strategies. Hierarchical linear modeling …
