A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk
Walden Dissertations and Doctoral Studies
Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …

Gatekeeper Suicide Prevention Training And Its Impact On Attitudes Toward Help Seeking, John Angelo Cascamo Jr.
Walden Dissertations and Doctoral Studies
Gatekeeper Suicide Prevention Trainings such as Question Persuade and Refer (QPR) are used to increase suicide awareness and teach participants basic suicide intervention skills. Previous researchers showed that QPR training increases knowledge of suicide risk factors and increases participants' willingness to intervene with individuals at risk of suicide. It was hypothesized that completion of QPR would also increase positive attitudes toward the utilization of mental health services and that this outcome would be more pronounced among male participants. The examination of attitudes was rooted in the theoretical framework of Ajzen's theory of planned behavior. The Inventory of Attitudes toward Seeking …
The Influence Of Hiv Stigma And Disclosure On Psychosocial Behavior, James Minson
The Influence Of Hiv Stigma And Disclosure On Psychosocial Behavior, James Minson
Walden Dissertations and Doctoral Studies
Human Immunodeficiency Virus (HIV) remains a serious public health issue, and many social factors are involved in virus transmission and treatment. The current conceptualization of how HIV status disclosure and perceived stigma of HIV diagnosis interact is undeveloped. This study was based on social cognitive theory and tested hypothesized positive relations between HIV serostatus disclosure, social support, and self-efficacy. In addition, self-rated HIV stigma was examined as a potential mediating variable. Participants were 109 HIV positive, mostly White gay men recruited via an online bulletin board. They completed the medical outcomes study social support survey, the general self-efficacy scale, the …
Discrete Trial Instruction: Comparing The Abbreviated Performance Feedback And Lecture Test Models, Tammy J. Dobbs
Discrete Trial Instruction: Comparing The Abbreviated Performance Feedback And Lecture Test Models, Tammy J. Dobbs
Walden Dissertations and Doctoral Studies
Growing media attention and a high diagnosis rate of autism places significant demand on the service industry to provide qualified staff to work with individuals who have autism. Discrete trial instruction (DTI) is one of the most sought-after treatment approaches for those individuals. However, there is a gap in research regarding the efficacy of training methods for those who train direct staff to implement DTI. This quantitative study used an applied behavior analysis basis, deriving from foundations of behavior theory, to compare the abbreviated feedback form (AFF) to the lecture test model (LTM) to understand which will improve direct staff's …
