An Examination Of The Relationship Between Adolescent Depression, Anhedonia, And Behavioral Therapy, Alison A. Delizza Aug 2019

An Examination Of The Relationship Between Adolescent Depression, Anhedonia, And Behavioral Therapy, Alison A. Delizza

Dissertations

Adolescent depression is a significant public health problem, however the current characterization of depression as a categorical label is problematic for understanding individual phenomenology, interindividual variability, and best treatment practices (Lewinsohn, Solomon, Seeley, & Zeiss, 2000). Anhedonia has been posited as a process underlying depression that may contribute to poorer outcomes (Gabbay, 2015). The current project examines large samples of adolescents diagnosed with depression to identify common features at a symptom level and the relationship these features have with behavioral therapy outcomes. Four phases of analyses were completed to 1) examine symptomology of multiple depressed adolescent samples in order to identify core features of depression in adolescents; 2) extend a factor analysis to a new sample to determine if the same factors on the Children’s Depression Rating Scale emerge; 3) determine if a prior finding that anhedonia is predictive of poorer outcomes replicates in a new sample from a large scale clinical trial; and 4) explore whether behaviorally oriented treatments appear to specifically target and diminish anhedonia symptoms. Results suggest that anhedonic symptoms ...


Preventing Sexual Victimization: An Assertiveness Training Program For Female Adolescents, Emily Morgan Dec 2018

Preventing Sexual Victimization: An Assertiveness Training Program For Female Adolescents, Emily Morgan

Dissertations

Unwanted sexual experiences occur too frequently in the United States and result in myriad deleterious consequences. The first instances of unwanted sexual experiences for females most frequently occur during adolescence (ages 12 to 17). Despite this, the majority of literature on sexual victimization and victimization prevention programs focus on college-aged females, thus leaving a need for research on prevention programs for adolescent females. The present study examined the effects of an assertiveness training program on the risk for sexual coercion among adolescent females. A behavioral skills training model (i.e. instruction, model, rehearsal, and feedback) was used to teach seven ...


Examination Of The Effects Of Computer Assisted Mindfulness Strategies With Adolescents In An Alternative High School Setting, Justin A. Moore Aug 2017

Examination Of The Effects Of Computer Assisted Mindfulness Strategies With Adolescents In An Alternative High School Setting, Justin A. Moore

Dissertations

Based on growing evidence that suggests mindfulness practices may improve psychological functioning, recent decades have seen a surge in mindfulness interventions and the use of technology as a means for teaching them. The primary purpose of this study was to examine the effects of four weeks of (twice weekly) training sessions using two computer-based strategies for teaching mindfulness-related skills to adolescents. The strategies included Breath Counting Training (BCT; Levinson et al., 2014) and Self-Compassion Training (SCT; Weng et al., 2013; Alberston, Neff, and Dill-Shackleford, 2014). Twenty adolescents (M age = 17.30; 40% male, 55% female, 5% gender neutral; 60% African ...


Combined Effects Of Mdma And Ethanol On Locomotor Activity And Place Conditioning In Male And Female Adolescent Sprague-Dawley Rats, Keli A. Herr Jun 2014

Combined Effects Of Mdma And Ethanol On Locomotor Activity And Place Conditioning In Male And Female Adolescent Sprague-Dawley Rats, Keli A. Herr

Master's Theses

MDMA, ("Ecstasy") is commonly abused in combination with ethanol (EtOH). Relatively few preclinical studies have investigated sex differences in animal models of polysubstance use. The current study employed a conditioned place preference (CPP) procedure to assess the behavioral effects of the co-administration ofMDMA /EtOH in 32 male and 32 female adolescent Sprague-Dawley rats. Following a 15 min habituation trial, eight 30-min conditioning trials were conducted in two- compartment chambers with different environmental cues. Before each drug conditioning trials, rats were administered intraperitoneal (i.p.) injections of MDMA(6.6 mg/kg), EtOH (1.5 g/kg), MDMA (6.6 mg ...
