Long-Term Effects Of Adolescent Fluoxetine Exposure On Hippocampal Gene Expression In Male C57bl/6 Mice, Anapaula Themann

Open Access Theses & Dissertations

Mood-related disorders, including depression and anxiety, are prevalent among children and adolescents. This poses a public health challenge, given their adverse impact on these young populations. Treatment with the selective serotonin reuptake inhibitor fluoxetine (FLX) is the first line of pharmacological intervention in pediatric patients suffering from affect-related illnesses. Although the use of this antidepressant has been deemed efficacious in the juvenile population, the enduring neurobiological consequences of adolescent FLX exposure are not well understood. For this reason, we explored for persistent molecular adaptations, in the adult hippocampus, as a function of adolescent FLX pretreatment. To do this, we administered …

Identifying Risk Factors For Ptsd Symptom Clusters In Maltreated, Multiracial Youth Using Nonparametric Modeling, Mallory Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Multiracial youth are one of the most at-risk racial groups for child maltreatment. Multiracial individuals are also more likely to report mental health concerns than other racial or ethnic groups. This study aimed to identify demographic and psychological risk factors that are unique to multiracial, maltreated youth with respect to PTSD symptoms (i.e., re-experiencing, hyperarousal, avoidance) through classification and regression tree (CART) analyses. Participants included 99 multiracial, maltreated youth directly following their placement in an emergency group shelter due to substantiated maltreatment. The first hypothesis was that female gender, English first language, questions related to guilt and self-blame, and depressive …

To Engage Or Disengage: The Impact Of Coping Strategies, Sex, And Stress History On Cortisol Reactivity Among Urban Adolescents, Madeline Curzon

College of Science and Health Theses and Dissertations

Stress affects people daily and can prove maladaptive to mental health if chronic or acute. Effective coping responses may mitigate the negative effects of intense or prolonged stress through physiological processes such as HPA axis activity. Previous research has found one specific coping dimension, engagement/disengagement, to be predictive of cortisol reactivity in response to lab-induced stressors. Sex and stress history also contribute to the relationship between coping and cortisol reactivity. However, these processes are not as well understood in adolescent populations and have not been explored across different types of stressors. The present study explored the relationship between coping and …

Resting State Functional Connectivity In The Default Mode Network: Relationships Between Cannabis Use, Gender, And Cognition In Adolescents And Young Adults, Megan Ritchay

Theses and Dissertations

Introduction: Cannabis is the most commonly used illicit substance in the United States, and nearly 1 in 4 young adults are current cannabis users. The psychoactive component of cannabis, THC, is active at cannabinoid receptors, type 1, or CB1 receptors. CB1 receptors play a critical role in neural development, and chronic cannabis use causes desensitization and downregulation of these receptors. Chronic cannabis use is associated with changes in resting state functional connectivity (RSFC) in the default mode network (DMN) in adolescents and young adults, although results are somewhat inconsistent across studies, likely due to differing methodologies. Additionally, cannabis effects appear …

Differences In Compulsive-Like Ethanol Consumption In Adolescent-Trained And Adult-Trained Rats Exposed To Acute Isolation Stressors, Maria J. Lopez

Seton Hall University Dissertations and Theses (ETDs)

The Pavlovian Conditioned Approach (PCA) procedure is an experimental procedure used with animals to induce compulsive-like behaviors directed towards an object conditioned stimulus (CS) paired with a sucrose pellet unconditioned stimulus (US) presented in a nearby food tray (sign tracking). When the object CS is an alcohol-containing bottle, the rats demonstrate compulsive-like interactions with the bottle object (e.g., approach, contact, and licking) that also results in alcohol consumption (drinking) in most rats. Compulsive alcohol drinking in a sign-tracking procedure is a result of the combined effects of schedule-induced compulsive-like behavior and the intake of alcohol (Tomie & Sharma, 2013).

The Relationship Between Neighbourhood-Level And Family-Level Factors And Sleep Problems Among Children And Youth, Katarina Mckenzie

Electronic Thesis and Dissertation Repository

There is little research on the effects of neighbourhood factors on child sleep outcomes. No study to date has investigated the interactive effects of neighbourhood and family socio-economic characteristics (SECs) on child sleep outcomes. This study aimed to fill this gap. Secondary data analyses were completed on two samples (children and youth) from the 2014 Ontario Child Health Study, a cross-sectional, province-wide sample of 10,802 children aged 4 to 17. Multi-level modeling was used to assess the relationship between child- (e.g., age), family- (e.g., negative parenting) and neighbourhood-level factors and their relationship to sleep outcome variables: problems falling asleep, problems …

Reducing Stigma Associated With Growing Up Poor: How To Create A More Equitable Future For Working Class Adolescents, Jessica Goodpaster

University Honors Theses

I examine how stigma associated with socioeconomic status (SES), or social class, has the potential to negatively impact individuals during adolescence. Specifically, I focus on the impact of class stigma, and the institutional barriers faced by adolescents as they prepare for adulthood. These barriers and the stress felt due to both stigmatization, and environmental stimuli specifically pertaining to low-income neighborhoods/environments, can hinder or alter the development of the four major domains of development: physical, social, emotional and cognitive development. Stigmatization has resulted in physically and socially isolating low-income communities from middle- or high-income communities, hindering social mobility for L-SES adolescents. …

An Investigation Of Developmental Precursors And Consequences Of Self-Sacrificing Behaviors In Young Adult Romantic Relationships, Emme Lis

Masters Theses, 2020-current

It has been well established that the early attachment relationship a child forms with their parent or caregiver is foundational in influencing subsequent relationships throughout life. Adolescence itself is also a critical developmental period for future relationship development. The current study therefore was interested in examining ways in which attachment orientations youth carry into adolescence combine with parental influences to shape teens’ future relational behaviors and attitudes in young adulthood. Specifically, the parental influences of promotion of autonomy and positive relatedness, as well as parental valuing of prosocial behaviors and self-directed behavior during adolescence were investigated in interaction with early …

Effects Of Adolescent Motivation And Personality On Adherence And Success In A Voluntary Residential Bootcamp Program, Lydia Sigurdson

Master's Theses

The Youth ChalleNGe Program is a voluntary program for adolescents who have dropped out of high school and is intended to address various needs of at-risk youth. As a result, individuals are motivated to enroll for an array of reasons. Though prior research on the Youth ChalleNGe Program has sought to identify individual factors that determine program outcomes, no study has considered motivation for enrollment as a predictor of program success. Further, personality traits related to goal setting and self-regulation may impact the relationship between motivation and program outcome. Archival data was gathered from 710 participants in the Youth ChalleNGe …

How An Adolescent Athlete's Status And Deviation From Masculine Norms Is Perceived By Adult Men: The Impact Of Observers' Masculine Ideology, Brandon C. Martin

Undergraduate Theses

Masculinity has been at the forefront of discussion surrounding social change in American popular culture. After consideration of the historical context of masculinity in the 20th century, development and sport were discussed. To evaluate the effects of adult men’s masculinity ideology on their perceptions of gender nonconforming behavior (pink nail polish), an adolescent male athlete target was utilized. A 2 x 2 between-subjects design used sport (football and swimming), and status (a freshman and a senior) in vignettes which described an adolescent male athlete. Participants’ unique attributes, such as degree of conformity to masculine norms, gender role conflict, and policing …

The Effect Of Depression On Adolescent Deviant Behavior And The Mediating Effect Of Autonomy, Theresa Lee

University of the Pacific Theses and Dissertations

The purpose of this study was to synthesize the relations among the adolescent need for autonomy in decision making process, depression, and tendencies for deviant or risk-taking behaviors as adolescents. Background variables such as socio-economic status, sex, race, previous academic achievement, parent warmth and support, resistance to peer pressure were controlled for. Using the NICHD database set, multiple regression analyses revealed that adolescent autonomy was not correlated with adolescent depression, and earlier depression at sixth grade was not a significant mediator of the effect of earlier deviant behaviors at sixth grade on later adolescent deviant behaviors. More importantly, however, the …

Adults’ Reflections On Their Lived Experiences With Adolescent Social Anxiety Disorder, Shelley Marie Skelton

Walden Dissertations and Doctoral Studies

Anxiety disorders are the most prevalent mental health disorders for children and youths, and social anxiety disorder (SAD) is the third most common anxiety disorder. SAD can negatively impact school performance, mental health, and healthy social development. In comparison to other forms of anxiety, current treatments for SAD have not been as efficacious. The purpose of this qualitative phenomenological study was to explore other factors of adolescent SAD, such as the role of resilience. The two research questions addressed the lived experiences of adolescents with SAD and how they developed resilience in relation to their SAD. Bronfenbrenner’s bioecological theory of …

Coparenting Among Families Of Treatment-Seeking Adolescents: Associations With Coping Behaviors And Psychological Adjustment, Andrew Joseph Flannery

Graduate Research Theses & Dissertations

In recent decades, the family literature has demonstrated that the influences of coparenting spread through the entire family system and also uniquely affect child and adolescent psychosocial outcomes. For example, extant evidence shows that coparenting influences the connection between marital conflict and adolescent psychosocial outcomes. However, the period of adolescence is underscored by novel stressors, as teenagers experience biological, psychological, social, and cognitive transformations. Moreover, the median age of onset for mood, anxiety, substance use, and impulse-control disorders is before 25 years of age and most frequently during adolescence. Additionally, the manner in which adolescents cope with stressors may buffer …

Fitting In: A Study On Adolescent Identity-Uncertainty And Group Entitativity, Isabela Ixchel Cruz-Vespa

Senior Projects Spring 2021

Uncertainty-Identity Theory hypothesizes that the more uncertain people are about themselves, the more likely they are to identify with groups as a way to define themselves and guide their behavior. Research has shown that this identification can happen to an extreme level when the group is highly entitative, or provides clear expectations for how group members should behave, think and feel, thereby resolving their uncertainty. Adolescence is a development period defined by self-uncertainty, and therefore also heightened vulnerability to highly entitative, extremist groups. This experiment tests the prediction that adolescents who are experiencing high self-uncertainty will be more likely to …

Co-Constructing Stigma: Treating Trauma In Adolescence, Isabelle Sanderson

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Public stigma and self-stigma are major factors that impede the seeking of mental health treatment as well as the development of an effective therapeutic alliance. This paper explores the co-creation of stigma dynamics from an intersubjective systems theory lens suggesting these dynamics may play a role for adolescent clients who have experienced significant trauma. Specifically, the potential overlooking and/or misdiagnosis of trauma-related experiences and symptoms often occurring with adolescents diagnosed with ADHD may be contributing to a co-constructed dynamic between the therapist and client to avoid an exploration of trauma that would be experienced as more stigmatizing, more threatening, and …
