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 …

Associations Between Adolescent Cannabis Use Trajectories And Anxiety, Jacqueline C. Duperrouzel

FIU Electronic Theses and Dissertations

Understanding the effects of cannabis use is critical for reducing adverse behavioral, social, and academic outcomes, particularly among adolescent users who are most at risk for cannabis related problems. Although support from both the animal and human literatures suggests the relationship between cannabis and anxiety may be associated with levels of use, much is still unknown. Thus, examining relationships between the most common mental health issue in adolescence and one of the most commonly used drugs is of great public health significance and impact. Prior longitudinal studies assessing effects of cannabis use on anxiety have not evaluated different patterns of …

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 …

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 …

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, …

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 …

Cognitive Behavior Therapy For Anxiety Disorders In Youth: Treatment Specificity And Mediation Effects, Ileana Hernandez

FIU Electronic Theses and Dissertations

The present study investigated the efficacies of Individual CBT (ICBT), Parent Relationship Skill Training (RLST, which targets increasing parental acceptance of youth and increasing autonomy granting) and Parent Reinforcement Skills Training (RLST, which targets increasing parental positive reinforcement and decreasing negative reinforcement). The specific aims were to examine treatment specificity and mediation effects of parenting variables. ICBT was used as a baseline comparison condition.

The sample consisted of 253 youth (ages 5-16 years; M = 9.38; SD = 2.42) and their parents. To examine treatment outcome and specificity, the data were analyzed using analysis of variance within a structural equation …

The Impact Of Maternal Acculturation, Youth Age, Sex And Anxiety Sensitivity On Anxiety Symptoms In Hispanic Youth, Maria Pienkowski

FIU Electronic Theses and Dissertations

Despite progress that has been made in the areas of maternal acculturation and internalizing symptoms in Hispanic youth, much remains to be learned about the relation between maternal acculturation and youth anxiety. The inclusion of cognitive vulnerabilities such as anxiety sensitivity (AS) further adds to the understanding the development of anxiety in Hispanic youth. Examining the role that youth age and youth sex play in the relation between AS and youth anxiety symptoms also can further understanding of the development of youth anxiety. Thus, the specific aims of this dissertation were to examine whether: (1) a confirmatory factor analysis (CFA) …
