Measurement Of Defusion: Further Validation Of The Drexel Defusion Scale, Christopher A. Briggs

Dissertations

Acceptance and Commitment Therapy (ACT) seeks to develop psychological flexibility through the engagement of the six interrelated processes. Four processes employ mindfulness and acceptance strategies and consist of acceptance, defusion, present moment awareness, and the contextualized self. Two other processes, values and committed action, are grouped with present moment awareness and the contextualized self and are termed behavior change strategies. One issue encountered by contemporary behavioral approaches in general, and ACT in particular, is the measurement of the proposed processes. Measurement is complicated by the functional nature of some of the repertoires described making the development of instruments for assessment …

A Single Session Of Acceptance And Commitment Therapy To Promote Health-Related Behavior Change: A Randomized Controlled Trial, Monica Barreto

Dissertations

The Centers for Disease Control and Prevention have identified physical activity, nutrition, and sleep as three key health-related behaviors that can help the prevention of chronic disease. Only a fraction of the population met the recommended guidelines across these domains. It is important to develop interventions that can be simultaneously focused, flexible, efficient, and efficacious as a means of impacting population health. This study examined the efficacy of a single 60-minute Acceptance and Commitment Therapy (ACT) session targeting health-related behavior change and compared it to an information-only wait-list (WL) control condition. Forty-five collegians (Mage = 22.35 [6.91], 78% female, 56% …

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 …

Examining The Effects Of Cell Phone Use On Caregiver Supervision And Child Injury Risk, Mckenna Corlis

Dissertations

Unintentional injuries are the leading killer of children in the United States. Research indicates caregiver supervision decreases child injury risk, but has not examined how different distractions may affect this relation. Specifically, research has not considered if and how caregiver cell phone use affects child injury risk. Given the prevalence and distracting effects of cell phones noted in previous studies, it is imperative to examine how caregiver cell phone use and child injury risk relate.

The present study examined how distractions influenced caregivers’ ability to tend to their child and their child’s engagement in risky behavior. Using a within-subjects design, …

Sexual Coercion: The Role Of Communication And Heteronormative Beliefs, Brianna Lindley Forbis

Dissertations

Sexual assault is a pervasive issue on college campuses, with large numbers of students experiencing sexual assault during their college careers (Fisher, Cullen, & Turner, 2000). Sexual assault is often perpetrated by a known offender, which has brought increased attention to forms of sexual assault that do not necessarily include violence or the direct threat of violence. Sexual coercion is one such construct that has received increased attention in the literature, with several studies finding associations between heteronormative beliefs and sexual coercion (Eaton & Matamala 2014; Haworth- Hoeppner, 1998; Vanwesenbeek, 1998). Aims of the current study included further exploring the …

Measuring Contextual Factors Associated With Experiential Avoidance Using A Behavior Analogue Paradigm, Meaghan M. Lewis

Dissertations

The purpose of the present study was to investigate the relationship between levels of state and trait experiential avoidance across two different contexts using behavior analogue methodology. Performance on the cold pressor task (threshold, tolerance, endurance, and intensity; Zettle et al., 2012) was compared to performance on a modified version of the Trier Social Stress Test (TSST; Kirschbaum et al., 1993) to obtain a behavioral measure of experiential avoidance that was standardized across these four behavioral indices. Data were collected from a convenience sample of undergraduate students (N = 133) from college classrooms on the campus of Western Michigan University. …
