Preclinical Behavioral Assessment Of Chronic, Intermittent Low-Dose Psilocybin In Rodent Models Of Depression And Anxiety, Harmony I. Risca

Dissertations

Recent studies have demonstrated the clinical efficacy of psychedelic-assisted psychotherapy for treatment-resistant depression and anxiety. Amidst the overall success of recent clinical trials using a single high dose of psilocybin, anecdotal reports indicate anxiolytic and antidepressant effects following a repeated low dose regimen. As therapeutic outcomes are often tightly intertwined with the individual’s subjective experience, animal models are used as objective measures to investigate the underlying mechanisms responsible for the putative antidepressant/anxiolytic effects of psychedelics. Three rodent models predictive of anxiolytic or antidepressant effects were used to evaluate effects of chronic intermittent low dose (CILD) psilocybin treatment; the Light/Dark conflict …

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 …

The Lived Experience Of Individuals With Chronic Back And Neck Pain, Depression, And/Or Anxiety, Tara L. Palmeri

Dissertations

More than 1.5 billion people worldwide suffer from chronic pain (CP). People who experience chronic pain are 20 to 40% more likely to meet criteria for an anxiety disorder, and three to four times more likely to be clinically depressed than their pain-free counterparts. The relationship between CP and mental health has been studied quantitatively; however, few researchers have investigated co-morbid CP and mental health through a phenomenological lens. The subjective nature of the relationship is not comprehensively addressed within the literature.

This qualitative phenomenological study explored (a) how individuals with chronic back and/or neck pain (CBNP) experience, understand, and …

Yoga As An Ancillary Treatment To Acceptance And Commitment Therapy For Depression, Jeralee M. Briggs

Dissertations

It is estimated that up to 30% of college students feel clinically depressed, and these feelings can lead to poor grades, substance abuse, unsafe sex, and suicide (National Institute of Mental Health, 2016). Acceptance and Commitment Therapy (ACT) has shown to be an effective form of psychotherapy for depression and was listed in 2014 as an evidence-based treatment for depressive disorders according to the APA Presidential Task Force on Evidence-Based Practice (2006). In addition to psychological treatment, various exercise interventions have been shown to be effective in reducing depressive symptoms (e.g., Rehorst, Wipfli, & Landers, 2009). Yoga is one such …

An Evaluation Of The Acceptability And Effects Of A Computer-Delivered Values-Based Behavioral Activation Treatment For Depression Among Older Adults, Kellie Reynolds

Dissertations

Depression is a common psychological disorder among older adults and is associated with serious secondary effects to health and social well-being. Behavioral activation has been found to be an efficacious treatment for depression. However, there is limited research on the treatment effects of behavioral activation with older adults. In general, older adults under-utilize mental health treatments. Computer-delivered treatments have been developed to address access and under-utilization. The purpose of this dissertation was to evaluate the acceptability and effects of a computer-delivered values-based behavioral activation treatment for depression in older adults. This study consisted of two phases. Phase I consisted of …

Learning To Learn And Naming Through Receptive And Expressive Identification, Kelli Perry

Dissertations

Poor or no language skills are typical of most preschool children with autism (American Psychological Association, 2013). Language can be divided into the two components of receptive, or listener, skills and expressive, or speaker, skills. Recommendations for sequencing language instruction vary across the different behavior-analytic instructional models (Lovaas, 1981; Barbara & Rasmussen, 2007; Sundberg & Partington, 1998; Sundberg, 2008). The current study sought to examine those recommendations using young children (three- to four-years-old) with limited vocal repertoires and to explore the acquisition of learning to learn (Harlow, 1949) and naming (Greer & Ross, 2007). This research (1) adds to the …

Testing A Model Of Maladaptive Perfectionism And Depression Symptoms: The Roles Of Emotional Disclosure, Emotion Regulation Strategies, Adult Attachment, And Shame, Angela M. Garrison

Dissertations

Previous research has supported a link between maladaptive perfectionism and higher levels of depression symptoms. However, researchers have not yet investigated the ways in which emotion regulation processes may mediate this relationship. Therefore, the primary purpose of this study was to evaluate emotional disclosure, emotional avoidance, and rumination as mediators of the relation between maladaptive perfectionism and depression symptoms. Additionally, this study also investigated the role that insecure attachment orientations play in the relationship between maladaptive perfectionism and use of particular emotion regulation strategies. Further, the role of shame in the emotion regulation processes of individuals with higher levels of …

A Brief Acceptance And Commitment Therapy Protocol For Depression In An Inpatient Setting: An Effectiveness Study, Lucas Broten

Dissertations

The present study sought to investigate the utility of a brief Acceptance and Commitment Therapy (ACT) protocol for the treatment of depression in an inpatient setting. ACT is a generally promising treatment for a variety of psychological issues. Thirty-nine participants were randomly assigned using and weighted, blocked distribution to either Treatment as Usual (TAU) or individual sessions of ACT in conjunction with treatment as usual (ACT). The study compared re-admission rates between the ACT intervention group and the TAU group at 3 and 6 months. In addition, the study examined the proposed mechanisms of change between groups and depression rates …

Computerized Behavioral Activation Treatment For Major Depressive Disorder And The Effects On Sexual Desire, Anthony G. Bonita

Dissertations

The present study was designed to examine the effects of a computerized behavioral activation treatment program on sexual desire, sexual behavior, and depression symptoms. Seven adults who met criteria for either major depressive disorder or dysthymic disorder were recruited from Kalamazoo, Portage, and surrounding areas in Southwestern Michigan. All participants completed at least five sessions of behavioral activation treatment, and six out of seven participants completed all ten sessions. Symptoms of depression, sexual desire, and sexual behavior were assessed at pretreatment and before each treatment session through a combination of the Beck Depression Inventory – II (BDI-II), the Revised Hamilton …

An Evaluation Of Social Capital's Effect On Depression Among Adolescents, Ezechukwu Awgu

Dissertations

Mental illness has been described as a “global burden of disease,” and depression accounts for a large part of the burden (Aslund, Starrin, Nilsson, 2010). In 2009, 35.7 percent of the adolescent population in the United States who reported past-year symptoms of a major depressive episode, for example, feelings of sadness, discouragement, loss of feelings of self-worth, and loss of interest in social activities, also used illicit drugs including marijuana, inhalants, hallucinogens, cocaine, heroin, and prescription-type psychotherapeutics for non-medical purposes (SAMHSA, 2009, APA, 1994). Additionally, substance abuse due to alcoholism was among the major causes of death for adolescents aged …
