Neuromodulation To Enhance Attention Training In Socially Anxious Adolescents, Daniella Vaclavik

FIU Electronic Theses and Dissertations

Anxiety and its disorders are prevalent and impairing in adolescents, often following a chronic course, and are associated with heightened prospective risk of depressive disorders, substance use disorders, and suicidal behaviors. Traditional interventions such as cognitive behavioral therapy (CBT) have yielded response rates that highlight the critical need to examine treatment outcome moderators in underrepresented populations (i.e., Latino youth), as well as identify and evaluate innovative and alternative interventions that are brief, efficacious, and grounded in neuroscience. In a series of three manuscripts, this dissertation project presents findings on moderators of CBT outcomes in Latino youth (Chapter II) and explores …

Examining The Influence Of Parenting Practices On Youth's Sleep Health During A Sensitive Developmental Period, Juliana Acosta Lievano

FIU Electronic Theses and Dissertations

Sleep problems among youth are highly prevalent and associated with mental and physical health concerns. During early adolescence, youth’s sleep health is at risk for disturbance, and problems with sleep around this developmental period have been shown to longitudinally predict escalating rates of anxiety and depression later in adolescence. Sleep-related behaviors are embedded within the family system and as such they are influenced by familial processes including parenting practices. However, the influence of parenting practice on young adolescents’ sleep health has been understudied. Moreover, there is limited evidence on the concept of nighttime parenting as it relates to youth’s sleep …

Building Bridges: A Brief School Readiness Intervention Designed To Guide Families Transitioning From Early Head Start To Head Start, Katherine A. Zambrana

FIU Electronic Theses and Dissertations

The transition into the early school years is a salient developmental milestone, which lays the groundwork for later school success. Parent involvement in children’s development and early learning experiences has been widely examined and identified as a strong predictor of children’s school readiness. Therefore, promoting positive parent involvement during the early school years and during developmental transitions is key to children’s later school success. Recognizing the importance of early school success, several programs have been developed to support children and families in the transition to kindergarten. Yet, as early as preschool, a number of children display significant behavioral and academic …

Tolerance To Psychostimulant Medication Among Children With Adhd, Fiona Macphee

FIU Electronic Theses and Dissertations

Medication is the most commonly received treatment for childhood Attention-Deficit/Hyperactivity Disorder (ADHD) with 90% of children with ADHD having received it at some point in their lives (Danielson et al., 2018). Central Nervous System (CNS) stimulant medication is a well-established short-term treatment for childhood ADHD (Pliszka, 2007). However, there is little support in the literature for long-term benefit of psychostimulants. One possible explanation for this lack of sustained effect is the development of tolerance to the drug. The current study aimed to examine possible evidence of short-term tolerance to stimulant medication, methylphenidate (MPH). Additionally, we investigated previous stimulant medication treatment …

Detecting Risk For Treatment Nonresponse Among Families Of Young Children With Behavior Problems: Candidate Tailoring Variables And Early Decision Points For Adaptive Interventions, Natalie Hong

FIU Electronic Theses and Dissertations

Heterogeneity in mental health treatment outcomes and high rates of treatment nonresponse highlight the need for adaptive interventions that align with precision mental health care approaches to tailor treatments according to individual differences in progress over time. Modern clinical trial methodologies and analytic strategies can inform dynamic mental health treatment decisions, but the potential to improve patient outcomes is only as strong as the extent to which selected tailoring variables (i.e., interim response factors that dictate whether treatment should shift course) accurately detect risk for treatment nonresponse. Identifying empirically informed tailoring variables and the most appropriate timepoint(s) to assess them …

Alliance-Outcome Associations In Interventions For Youth Internalizing Disorders: Identifying Mediators And Moderators, Deepika Bose

FIU Electronic Theses and Dissertations

Suboptimal treatment response rates in interventions for youth internalizing disorders (anxiety, depression, OCD) highlight a critical need to enhance intervention outcomes. My dissertation project addresses this need by identifying therapeutic process variables that predict intervention outcomes, and examining how, for whom, and under what circumstances they contribute to outcomes. In a series of three manuscripts, I present findings on a systematic review and meta-analysis of alliance-outcome associations in youths receiving intervention for internalizing disorders (Chapter II) and examine variables that may explain or influence alliance-outcome associations in interventions for internalizing problems in university-based (Chapter III) and usual care …

Examining Positive Behavioral Supports For Children With Challenging Behaviors Across Culturally And Linguistically Diverse Head Start Settings, Bridget Poznanski

FIU Electronic Theses and Dissertations

Persistent challenging behaviors occur in approximately 30% of children in Head Start, yet only 2% receive services. Children with persistent challenging behaviors in Head Start do not experience the same academic benefit as their peers. Left untreated, behaviors persist and are related to a number of adverse outcomes, which disproportionately impact children from low-income, culturally and linguistically diverse backgrounds. Preschool staff feel unprepared to manage challenging behaviors and experience high levels of stress and burnout, indicating need for workforce enhancement. Though interventions that address challenging behaviors in Head Start exist, these programs lack wide dissemination and rely heavily on coaching, …

Exercise, Cognition, And Cannabis Use In Adolescents, Ileana Pacheco-Colón

FIU Electronic Theses and Dissertations

Heavy and/or chronic cannabis use has been associated with neurocognitive impairment and decline, often in domains such as memory and executive functioning. On the other hand, exercise has been linked to positive effects on brain and cognitive health across the lifespan, as well as to better substance use outcomes. Despite this, little is known about the ways in which exercise could help prevent or ameliorate adverse cannabis-related outcomes among adolescents.

Through three separate studies, the current dissertation examines interrelations among exercise, cognition, and cannabis use in children and adolescents in an effort to determine whether exercise can prevent or ameliorate …

Considering Culture And Context: A Mixed-Methods Approach To Examining Adolescent Engagement And Parent Satisfaction In Urban Out-Of-School-Time Programs, Jacqueline Oluwakemi Moses

FIU Electronic Theses and Dissertations

Adolescents of color living in poverty are at elevated risk for mental health problems with limited access to quality care, and 21% of youth in poverty are diagnosed with mental health disorders that, left untreated, lead to significant long-term consequences. Positive future orientation – optimistic expectations for graduation, gainful employment, and healthy relationships – among vulnerable adolescents has been identified as a unique protective factor associated with positive mental health trajectories. Out-of-school-time (OST) programs in neighborhood settings can promote positive future orientation and maximize benefits for adolescents, but we know little about cultural and contextual influences on youth enrollment and …

Promoting School Readiness In At-Risk Children: An Evaluation Of A Behavioral Parent Training Program In An Early Childhood Community Setting, Randi J. Cheatham-Johnson

FIU Electronic Theses and Dissertations

Behavioral parent training (BPT) is the gold standard for the treatment of externalizing behavior problems in young children. However, many programs have failed to consistently replicate positive outcomes in economically and socially disadvantaged populations. Given the lasting negative impact of early behavioral problems on youth, families, and society as well as the heightened risk such families face, it is important to examine BPT within particularly vulnerable populations. A pilot open trial of a novel BPT, the School Readiness Parenting Program (SRPP), was conducted to examine the acceptability, feasibility, and promise of the manualized treatment as a standalone intervention for economically …

Examining Maternal Emotion Regulation In Children With And Without Adhd: A Multimodal Approach, Alexis Garcia

FIU Electronic Theses and Dissertations

Objectives: Our study utilized a multimodal approach to explore profiles of emotion regulation (ER) in mothers of young children with and without attention-deficit/hyperactivity disorder (ADHD). We also sought to understand how parent factors (i.e., skills, stress, ADHD symptoms) as well as child factors were associated with membership to these profiles. Methods: The final sample consisted of 182 parent-child dyads. Sixty-six children were in the typically developing group (Mean age = 5.47, SD = .90, 74.2% males), and there were 116 children in the ADHD group (Mean child age = 5.41, SD = .75, 80.2% males). Dyads completed a stress-inducing task …

The Effects Of Childhood Adversity, Juvenile Arrest, And Self-Regulation On Adults With Delinquency Histories, Michelle Ann Rhoden

FIU Electronic Theses and Dissertations

Previous studies reported that childhood adversity has debilitating effects on adult well-being. A high prevalence of youths with delinquency histories experience childhood adversity and are at high risk for lasting negative outcomes. Research identifies that the disruption in self-regulation (SR) development explains the effects of childhood adversity on well-being outcomes.

Using data from Add Health, a national study, this dissertation (1) developed a valid and reliable measure of adult SR deficiency, (2) assessed the mediating effects of adult SR deficiency on the association between childhood adversity (i.e., child maltreatment [CM], violent victimization [VV], and economic hardship [EH]) and adult well-being …

Attentional Processes In Anxiety: Examining Threat-Related Attention Bias And Attentional Control In Anxious Youth, Raquel Melendez

FIU Electronic Theses and Dissertations

Attention bias modification treatment (ABMT) is a computer-administered intervention informed by theoretical models implicating the role of attentional processes in the etiology and maintenance of anxiety. Attention bias modification treatment presents an innovative, cost-effective approach to meeting demand for treatment of anxiety disorders; however data are limited regarding long-term outcomes and related predictors of ABMT treatment outcomes in youth. Therefore, the present study examined long-term outcomes of ABMT as a standalone or adjunctive treatment in 74 youth referred to an anxiety disorders clinic. Three groups of youth (ages 9 to 22) were identified and assessed approximately one to six years …

The Effect Of Methylphenidate On Associative Learning Among Youth With Attention-Deficit/Hyperactivity Disorder, Amy R. Altszuler

FIU Electronic Theses and Dissertations

Despite strong evidence supporting the short-term efficacy of interventions for youth with Attention-Deficit/Hyperactivity Disorder (ADHD), and despite the fact that the majority of youth with ADHD receive treatment for the disorder at some point over the course of childhood, the long-term prognosis for individuals with ADHD remains poor. One potential explanation for the gap between short-term efficacy and long-term outcomes is that the most common intervention for youth with ADHD, stimulant medication, paradoxically undermines children’s abilities to learn from contingencies through their action on the dopaminergic system. The dynamic dopamine theory posits that by increasing levels of dopamine, stimulant medication …

Poly-Strengths Skill Building For Urban Teens At High-Risk For Violence Exposure: Leveraging Community After-School Programs To Promote Youth, Kelly D. Cromer M.S.

FIU Electronic Theses and Dissertations

Violence exposure increases teens’ risk for emotion dysregulation, anxiety, depression, and aggression towards peers. Urban teens are disproportionately more likely to be exposed to violence and less likely to receive mental health services. Community after-school programs can help to reduce these disparities by offering opportunities for skills development and mental health promotion to mitigate risk associated with violence exposure.

The current study examined the implementation and promise of brief meditation and sleep health journaling activities infused within a pre-existing parks-based after-school program for black and Latinx teens. Data include pre-/post-measures of violent and non-violent adversity, emotion regulation, anxiety, depression, and …

Self-Concept In Children And Adolescents As A Lever For Change In Academic Success For Under-Served Youth, Robert Ray Ogle

FIU Electronic Theses and Dissertations

Children and adolescents in under-resourced urban communities simultaneously experience higher rates of major life stressors, including mental health problems, and less access to the services needed to address these concerns. The combination of high need and few resources makes identifying broadly effective, resource-minimal interventions a critical goal. Amongst potential targets for intervention, academic success, particularly graduating from high school, predicts positive life outcomes across a wide range of health factors. To be effective in supporting academic success in under-served communities, an intervention must be universally applicable, inexpensive, and easy to deliver with fidelity. The current study examined the promise of …

Improving Satisfaction, Engagement And Clinical Outcomes Among Traditionally Underserved Children Through Cultural Formulation, Amanda Lucia Sanchez

FIU Electronic Theses and Dissertations

Economically disadvantaged and ethnic/racial minority children are more likely to suffer from disruptive behavior problems than their middle-to-upper-income Caucasian counterparts, yet they are less likely to receive quality care and are more likely to drop out of treatment services. Disparities in the reception of and engagement with mental health services suggests that standard mental health practices may not properly consider the unique cultural context of child mental health problems in traditionally underserved families. Initial research focused on adult populations has suggested that incorporating the brief Cultural Formulation Interview (CFI) as part of baseline assessment can promote improved medical communication, leading …

Cognitive Factors And Parasympathetic Regulation As Interacting Mechanisms Of Attention-Deficit/Hyperactivity Disorder, Anthony R. Ward

FIU Electronic Theses and Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is among the most commonly diagnosed mental health disorders in childhood, and yet, the causal mechanisms of the disorder remain unclear. Deficits in attention regulation, inhibition, and working memory are frequently proposed as core mechanisms of ADHD, but these deficits are highly heterogeneous at the individual level, which hampers advances in understanding the etiology of the disorder. Recent research has shown that parasympathetic nervous system (PNS) regulation is linked to cognitive function and emotion regulation; atypical PNS regulation is associated with problems in these domains as well as higher risk for psychopathology overall. This dissertation examined aspects …

The Effect Of Parent Emotion-Related Talk On Infant Behavior And Emotion Regulation, Nicole Elise Lorenzo

FIU Electronic Theses and Dissertations

Early parent-infant interactions play a critical role in the social, emotional, and behavioral development of children. While several aspects of parent-infant interactions have been thoroughly examined, parent emotion socialization has not been examined to the same extent. The current work aimed to examine the development of parent emotion-related talk in mothers of infants with and without elevated behavior problems in two studies. The first study examined the developmental trajectory of parent emotion-related talk among mothers of infants with and without elevated behaviors. Furthermore, a secondary goal of the study was to examine the effect of parent emotion-related talk on infant …

Reducing Risks For Anxiety And Depression Among Urban Youth: Leveraging After School Programs To Promote Emotion Regulation, Erin R. Hedemann

FIU Electronic Theses and Dissertations

Rates of internalizing disorders in childhood are around 10% and higher among racial/ethnic minority youth and youth living in poverty. Targeting empirically derived processes associated with anxiety and depression may be an efficient and effective way to minimize risks for internalizing symptoms and impairment. Deficits in emotion regulation (e.g., increased use of emotional suppression, decreased use of cognitive reappraisal) are associated with anxiety and depression in youth and improve with treatment. The current study examined the acceptability and promise of an intervention targeting these emotion regulation strategies in the context of an after-school music program. Reflecting a community-based participatory research …

Evaluating Intensive Group Behavioral Treatment For Children With Selective Mutism, Danielle Cornacchio

FIU Electronic Theses and Dissertations

Selective mutism (SM), an anxiety disorder most commonly presenting in childhood, is characterized by a failure to speak in certain social situations. Due to its unique presentation (e.g., lack of speech) and low prevalence, expertise in the treatment of SM is scarce, leaving many affected families without access to care. Intensive Group Behavioral Treatment (IGBT) allows families to travel to a specialty clinic to receive a course of treatment in a single week. This study is the first to evaluate IGBT for SM in a randomized controlled trial. 29 children aged 5-9 with SM were randomized to immediate IGBT or …

Self-Regulation As A Transdiagnostic Predictor Of Treatment Response For Preschoolers With Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder, Rosmary Ros

FIU Electronic Theses and Dissertations

The current work examined the feasibility and initial efficacy of the Summer Treatment Program for Pre-kindergarteners (STP-PreK) for 37 preschoolers with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Parents and teachers reported on children’s behavior, social/adaptive skills, executive functioning (EF), and emotion regulation (ER). Children completed a standardized achievement and EF battery and an emotion knowledge task. Improvements were reported in parent rated hyperactivity, inattention, aggression, and social and adaptive skills. Children also improved performance across achievement, emotion knowledge, and EF, and were rated by parents as having better EF and ER. Findings highlight the initial efficacy of an …

Identifying And Intervening On Neural Markers Of Attention To Threat In Children With Anxiety Disorders, Michele Bechor

FIU Electronic Theses and Dissertations

Objective: Attention Bias Modification Training (ABMT) for anxiety aims to train attention away from threatening stimuli and toward neutral stimuli. Although ABMT shows promising anxiety reduction effects in children and adolescents, no study has examined its influence on neural indicators of attention measured using event-related potentials (ERPs) in children or adolescents (i.e., youths). The present study examined the influence of ABMT on the P1, N170, P2 and P3 ERP components during completion of the emotional faces dot probe task in youths with anxiety disorders who failed to respond to cognitive behavioral therapy. Method: Thirty youths (M age = 11.97, …

Longitudinal Effects Of Peer, School, And Parenting Contexts On Substance Use Initiation In Middle School Adolescence, Barry Allen Ladis

FIU Electronic Theses and Dissertations

Substance use initiation (SUI) among adolescents is a critical public health concern. Research indicates SUI in middle adolescence increases the risk of substance use in adulthood and later dependence, which can result in deleterious consequences for youth, family relationships, and community (Substance Abuse and Mental Health Services Administration, [SAMSHA], 2014). This study investigated the role of involvement with deviant peers, school connectedness, and parenting quality on SUI (e.g., alcohol, cigarettes, and marijuana) in middle adolescence using secondary data from a 5-year longitudinal study (N = 387). First, exploratory factor analyses and confirmatory factor analyses with a separate independent sample …

Priming For Honesty: A Novel Technique For Encouraging Children's True Disclosures Of Adult Wrongdoing, Allison P. Mugno

FIU Electronic Theses and Dissertations

Children are often involved in the legal system as victims of maltreatment, and their disclosure of adult wrongdoing is necessary to initiate effective legal responses and protect them from continued abuse. However, external pressures and children's perceptions of the consequences of truth-telling (e.g., punishment, removal from the home) may result in the delay of disclosure or failure to disclose altogether. Research examining techniques for promoting children's truth-telling has almost exclusively relied on explicit requests to tell the truth (e.g., a promise, reassurance, assessments of conceptual knowledge and moral discussions), and the success of these techniques has varied. The present study …

Jarnail Singh Bhindranwale: A Charismatic Authority And His Ideology, John P. Cibotti

FIU Electronic Theses and Dissertations

Sikh leader Jarnail Singh Bhindranwale’s militant and masculinist discourses were embraced by Punjabi Sikhs because of his presence as a charismatic authority, a concept first developed by sociologist Max Weber to understand the conditions surrounding and personal qualities of a figure which attracts followers. The rebellion he led in Punjab resulted from his radical exploitation of issues concerning the Sikh community. Religion was wielded as a tool, legitimizing Sikh violence as commanded by the Gurus. Radical interpretations of Sikh scripture and folklore were initially preached to rural, less educated crowds. While his sermons brought out their frustrations with the government, …

Cognitive Beharioal-Therapy For Child Anxiety: Long-Term Follow-Up And Predictors Of Long-Term Outcomes, Cristina T. Del Busto

FIU Electronic Theses and Dissertations

Anxiety and its disorders are highly prevalent in childhood and adolescence, and are associated with impairment in social and academic functioning. Empirical evidence has accumulated demonstrating the efficacy of cognitive-behavioral therapy (CBT) for youth anxiety disorders delivered in individual, group, and parent formats. This dissertation study compared two of these formats, a youth only individual format, and two types of parental involvement formats to answer questions related to the long-term diagnostic outcomes and psychosocial functioning outcomes of youth who receive CBT for anxiety disorders. Specifically, this dissertation sought to compare individual and parent involvement to determine whether targeting parenting behaviors …

Anxiety And Callous-Unemotional Traits: Physiological And Behavioral Responses To Others' Distress, Kathleen I. Crum

FIU Electronic Theses and Dissertations

Research documents considerable anxiety-related heterogeneity in youth with callous-unemotional traits (CU), a pattern of callousness and shallow emotionality (Frick & Ellis, 1999) associated with lasting impairment (Fontaine et al., 2011). This heterogeneity may relate to behavioral differences, with the presence of both CU and anxiety associated with increased questionnaire-based reports of aggression and/or historical documentations of past aggression (Kahn et al., 2013). Anxiety in CU youth is associated with greater attention to others’ distress cues (Kimonis et al., 2012) compared to CU-only counterparts, in contrast to the decreased distress-cue attentiveness thought to contribute to aggression in CU youth (Dadds et …

Reward Responsivity In Parenting: Development Of A Novel Measure In Mothers, Chelsey M. Hartley

FIU Electronic Theses and Dissertations

The purpose of the current dissertation was to develop a measure of mother’s reward responsivity in parenting. I proposed that deficits in reward responsivity may contribute to maladaptive parenting behaviors, especially among depressed mothers. Reward responsivity is conceptualized as an individual difference in reactivity to pleasurable stimuli and represents a key motivational component that could contribute to the frequency and quality of mothers’ interactions with their infants.

To empirically evaluate the link between mother reward responsivity, behaviors towards their infant, and infant behavior outcomes, a measure of reward responsivity in relation to parenting behavior was needed. The current dissertation addressed …

Parent-Child Interaction Therapy As A Family-Focused Approach For Young Children With Traumatic Brain Injury, Dainelys Garcia

FIU Electronic Theses and Dissertations

Traumatic Brain Injury (TBI) is the leading cause of death and disability in children and adolescents in the U.S. and disproportionately affects young children. The negative consequences of early childhood TBI include deficits in behavior and attention, cognitive abilities, and academic skills. Behavior problems in particular are one of the most common and persistent consequences following TBI in young children. Therefore, interventions are needed that target the adverse effects of TBI on behavior. The purpose of the current work was to examine the initial outcome, feasibility, acceptability, and satisfaction of a time-limited and intensive format of Parent-Child Interaction Therapy (PCIT) …
