Exploring Unintended Pregnancy In The United States Military: A Phenomenological Approach, Mary Kathryn Phillips

Dissertations

Nearly half of the 6.7 million pregnancies in the United States each year are unintended. The U.S. unintended pregnancy rate is significantly higher than the rate in many other developed countries. By age 45, more than half of all American women will have experienced an unintended pregnancy, and three in ten will have had an abortion. Previous empirical research aimed to fix the rate of unintended pregnancy before it was adequately explored. The rationale for this study emanated from the belief that interventions intended to reduce the rate of unintended pregnancy will be more successful if the essence of unintended …

Sleep Disordered Breathing And Pregnancy: Prevalence And Outcomes At Delivery, Ryan Lyle Nations

Dissertations

Introduction
Sleep Disordered Breathing (SDB) during pregnancy is associated with maternal and neonatal morbidity, and in-hospital mortality. A recent prevalence study using the Nationwide Inpatient Sample reported an obstructive sleep apnea (OSA) prevalence of 7.3 per 10,000 in 2013, a rate of 24% per year over the last decade. The rise in prevalence mirrors the rise in obesity. Military Treatment Facilities (MTF) have seen an increase in obesity and related co-morbidities with an unknown prevalence of SDB. Most studies have been conducted in high-risk populations; the general prevalence of SDB and its association with adverse pregnancy outcomes in a military …

The Effects Of Schedule Density Of Reinforcement For Alternative Behavior On Resurgence, Kathryn M. Kestner

Dissertations

Resurgence is the reemergence of a previously extinguished response when an alternative response no longer produces reinforcement. Although returning to previously successful methods for obtaining reinforcement is likely advantageous, resurgence also occurs in the form of treatment relapse. An individual may return to problematic behavior (e.g., aggression, self-injury, drug use) when an alternative behavior (e.g., communication response, coping skill, social behavior, etc.) is no longer successful at producing a reinforcer. Behavior analysts rely on treatments based on differential reinforcement of alternative behavior, and resurgence has been demonstrated following changes to reinforcement schedules due to errors in treatment integrity or intentional …

Increasing Physical Activity In Young Adults With Autism Spectrum Disorder, Katherine B. Lalonde

Dissertations

Experts recommend that individuals walk 10,000 steps or more per day and doing so has been shown to have several health benefits. Unfortunately, many people fall short of 10,000 steps per day. Exercise levels are characteristically lower in people with Autism Spectrum Disorders (ASD) than in people without ASD. The present study comprised two experiments that used goal setting and reinforcement to increase physical activity in young adults with ASD. The first study employed a multiple-baseline-across-participants design in combination with a reversal design to determine the effects of a treatment package on the number of daily steps taken by young …

Choices Related To Maximizing Quality Of Life At End Of Life, Theresa Lynn

Dissertations

Humans, including those residing in the United States, can live in denial of their own mortality. Because of this, futile care is sometimes provided, often at great monetary expense and for little or no return in terms of quality or length of life. At least two opportunities exist for making choices regarding care at the end of life in the U.S.: completing advance directives and choosing hospice care. This dissertation consists of three studies related to this topic. The first is a quantitative study about advance directives and attitude toward death. The advance directive completion rate among adults in the …

Preferences For Evidence-Based Depression Treatments: An Emphasis On Patient-Focused Care, Lauren A. Frye

Dissertations

Research indicates most depressed patients in the general U.S. adult population seek depression treatment in primary care settings where the prevailing method of treatment is antidepressant medication. Although primary care physicians regard this approach as a preferable first line method of depression treatment, studies indicate many patients do not. Several studies have found depressed patients in these settings prefer psychotherapy or counseling over anti-depressant medication. Many advocate patient preferences should be integral to the treatment decision making process. There is a demonstrated propensity towards psychotherapy or counseling over antidepressant medication among depression patients. However, it is unclear which psychological depression …

An Evaluation Of The Primary Care Providers’ Perspective Of The Effects Of Moderate Alcohol Consumption On Health, Gisele Tchamba
