Major Depressive Disorder: Precursors, Predictors, And Coping Mechanism Among Undergraduate Students, Grace Antia Bickham

Walden Dissertations and Doctoral Studies

Major depressive disorder (MDD) is common among college students. The disease perpetuates depressive symptoms and potentially leads to chronic depressive episodes. Existing literature has shown that students who use both cognitive and behavioral maladaptive coping skills are more prone to endure depressive symptoms and poorer academic performance. Despite these known associations, little research has examined the relationship between coping skills and self-efficacy in response to warning signs of MDD in college students. This study sought to fill the gaps in the research of MDD related to precursors, predictors, and coping mechanisms among undergraduate students in a national sample of U.S. …

Relationship Between Modality And The Degree Of Knowledge Retention In Bioterrorism Training, Gaylon Rashun Crawford

Walden Dissertations and Doctoral Studies

A public health workforce must be trained to react quickly, especially in the case of terrorist attack. Political leaders and emergency management experts have often cited inadequate emergency training as a contributing factor in the public health system's failed preparations for a bioterrorist event. As a result of these failures, billions of dollars have been allocated towards correcting infrastructure deficiencies including training for public health nurses (PHNs), who are critical to a communitywide medical response. This quantitative study used Pearson's correlation and a multivariate regression analysis to evaluate the most effective modality of bioterrorism training (BTT) for PHNs working in …

Differences Between For-Profit And Nonprofit Hospitals: Perceived Quality And Access, Michael Ray Eiland

Walden Dissertations and Doctoral Studies

Despite a large body of literature addressing the issue, questions remain about whether nonprofit hospitals provide more community benefit than do for-profit hospitals. This lack of information impacts governments, hospitals, and the healthcare industry, as stakeholders attempt to generate requirements to which hospitals should adhere to maintain nonprofit status, and thus tax exemption. This study addressed this lack of information by examining U.S. hospitals through the lens of stewardship theory to determine whether nonprofits are better stewards of the public good than for-profits, and thus likely to provide higher quality and access. The study applied logistic regression to Centers for …

Psychosocial Predictors Of Successful Bariatric Surgery, Rodney D. Grim

Walden Dissertations and Doctoral Studies

Obesity is an epidemic that can lead to a wide range of physical and mental problems. When traditional weight-loss methods are not effective, bariatric surgery is a viable weight-loss option. While previous researchers have investigated the role of psychological factors in relation to obesity, few have investigated psychological factors as predictors of weight loss and complications after bariatric surgery. The purpose of this study was to determine the prevalence of psychological disorders/conditions (e.g., depression and abuse) in the study population, evaluate weight and psychosocial variables before and 6 months after weight-loss surgery, and identify psychosocial factors that are predictors of …

Bright Facet Sign And Its Association With Demographic And Clinical Variables, Gary Andrew Longmuir

Walden Dissertations and Doctoral Studies

Low back pain has a significant impact on global public health and economics. The bright facet sign (BFS), a common finding on magnetic resonance imaging (MRI) of the lumbar spine, is associated with low back pain. While degenerative joint disease (DJD) affects low back pain, its presence appears independent of the BFS at the disc and facet joints at the same spinal level. Increased BMI, considered a risk factor for DJD, has an inverse association with the BFS. The independent relationship of DJD and the BFS is poorly understood and may represent a previously unreported pain pathway. In this nested …

Induction Of The Novice Teacher In Urban Schools, Janice Marie Ridley

Walden Dissertations and Doctoral Studies

New teachers entering the urban pre-K-12 school setting require an induction program to perform their teaching duties. Despite modifications to improve an existing induction program, novice teachers in a Midwestern urban school district were underperforming in the classroom, leaving administrators to address new teacher turnover and a disrupted learning process for students. Drawing from Knowles's adult learning theory and state guidelines to fulfill federal legislation mandates for proper induction, this qualitative case study was designed to explore beginning teachers' perceptions of the modifications in the district's induction program. A sample of 8 novice teachers was recruited to participate in open-ended, …

Mri As An Adjunct To Conventional Mammography Screening For Cancer In Dense Breast Tissue, Rachel Sunmattie Connett

Walden Dissertations and Doctoral Studies

Diagnostic methods to effectively image dense breast tissue (DBT) can pose challenges for breast cancer screening. While conventional mammography is the gold standard for breast cancer screening, this technique has a low sensitivity to DBT and can miss about 78% of cancers in DBT, but magnetic resonance imaging (MRI) has a high sensitivity for imaging DBT, and produces a smaller number of false positives. The purpose of this study was to determine the extent to which conventional mammograms can miss breast cancer in women with DBT and to determine if an adjunct method of imaging DBT might detect breast cancers …
