The Health Belief Model was used to study HIV/AIDS beliefs of 419, 18 to 24 year old, never married, sexually active, heterosexual college students and predict their AIDS preventive behaviors from a larger sample of 662 college students. The structural properties of the scales used were evaluated using confirmatory factor analysis. Recent preventive behaviors were predicted in a LISREL Structural Equation Modeling analysis.

This dissertation breaks new ground. It examines the perceptions of older adults towards AIDS prevention. Using the National Health Interview Survey, 1988: AIDS Knowledge and Attitudes Supplement, a modified Health Belief Model is developed. Despite the low number of older adults 55+ with AIDS, some extenuating circumstances increase their risk of AIDS contraction. Older adults have lower levels of knowledge about AIDS, weaker immune systems and receive more blood transfusions. Societal influences include educational neglect at the hands of physicians, healthcare workers and social service personnel. The first stage of the dissertation involved establishing older adults as an at-risk population through an extensive literature review. Next, the data was described utilizing frequencies, correlations and factor analysis. Frequencies clearly indicated that older adults in the data set had low levels of AIDS knowledge and did not view themselves at risk for AIDS contraction. Correlations between the variables were minimal. A modified Health Belief Model was developed and tested. Multiple regression determined that minimal variation in the two dependent variables, "Perceived Effectiveness of Effective Methods to Prevent AIDS Contraction" and "Perceived Effectiveness of Ineffective Methods to Prevent AIDS Contraction" was accounted for by the independent variables. Although F ratios allowed rejection of the two null hypotheses, beta weights were low. Adjusted R^2's accounted for only 21% and 16% respectively of the variation in the dependent variables. Finally, discrepancies in the model were determined and recommendations made for further research. Most health belief models concentrate on individual social-psychological variables. Due to AIDS' societal consequences, it is proposed that societal providers of education: physicians, social service workers and healthcare personnel need to be included in the model. Recommendations were made for additional research into sexual behavior of older adults and exploration of available training of physicians, healthcare and social service professionals. Finally, recommendations were made to provide training and education for both professionals as well as the elderly to prevent their growth into an at-risk population.

Because of the high and rapidly increasing cost of health care, wellness has become a significant issue for both health care practitioners and the general public. This research examines the issue of wellness and seeks to develop a model that identifies the factors that are most significant in explaining why people engage in wellness activities. A questionnaire was mailed to a sample (n = 499) randomly selected from the general population of the United States. Predictor variables are the demographic variables of age, income, education and gender together with the cognitive variables of self-actualization, benefits of wellness behavior, health locus of control and threat to health. Dependent variables are the health-seeking behaviors of exercise, stress management, nutrition, health responsibility and social support. Canonical correlation, t-tests, regression and analysis of variance are used to analyze the data. Chapter one presents two existing health models. The first presents prevention or threat to health and the second proposes self-actualization as motivating wellness behavior. The research model combines the two models. Chapter two presents relevant studies in the literature regarding use of multivariate models in consumer behavior, dimensions of wellness and empirical findings of wellness-related research. Chapter three presents the research hypotheses, research design and techniques of analysis. Chapter four presents analysis of the data and results of statistical tests. Conclusions and limitations of the research are discussed in chapter five along with recommendations for further research. The study finds threat to health as the strongest driver of wellness behavior followed closely by self-actualization thus supporting the study model. Results indicate that older persons and females perform more wellness behaviors than do younger individuals and males. Two 3-way interactions were found: (1) Income, age and marital status; (2) Education, age and marital status. Internal locus of control was not found to influence wellness behavior.

Background: Current literature on caregivers of children with chronic illnesses and developmental disabilities primarily focuses on negative aspects of adjustment, with maternal stress and depression as common outcome variables (Duvdevany & Abboud, 2003; Shin and Crittenden, 2003). While these pediatric caregivers have been shown to struggle more than caregivers of typically developing children, the possibility of positive psychological outcomes from such an experience is only beginning to be explored (Kim, Greenberg, Seltzer & Krauss, 2003; Scallan, Senior & Reilly, 2010). One such positive outcome is the idea of Posttraumatic Growth (PTG), a construct for which a widely accepted theoretical model exists (Tedeschi & Calhoun, 2004). This model has yet to be empirically validated and fails to provide an exhaustive picture of PTG. The current study aims to document this phenomenon among caregivers of children with Williams, empirically evaluate a portion of the proposed theoretical model, and explore possible extensions of the model in the form of health behaviors. Methods: Participants included 104 primary caregivers of children with Williams syndrome who were recruited through the Williams Syndrome Association List serve. Caregivers completed an online survey through SurveyMonkey software that included the posttraumatic growth inventory, the deliberate rumination scale, the MOS social support survey, and the taking care of yourself questionnaire. Results: The vast majority of caregivers reported some degree of growth following a diagnosis of Williams syndrome (M =55.91, SD =22.63), consistent with reports of other pediatric caregivers (Polantinsky & Esprey, 2000). Further, perceived social support was found to predict posttraumatic growth, F(2,73) = 2.488, p=.029, consistent with model predictions. However, perceived social support was not predictive of an increase in deliberate rumination, F(2,72) = 0.143, p=.867, failing to support the mediational model. Finally, posttraumatic growth was not found to predict health behaviors, although those caregivers who reported more posttraumatic growth also reported being less bothered by sleep-related caregiving burdens. Conclusion: Posttraumatic growth is prevalent among Williams syndrome caregivers, indicating the need for future research in facilitating this process among pediatric caregivers and patients alike. Further, a better understanding of the cognitive constructs involved in the posttraumatic growth process is essential. This improved understanding will facilitate more accurate measurement tools for evaluating these cognitive processes along with additional clarity with regards to the theoretical model. Finally, the identification of health behaviors and health belief constructs that are impacted by posttraumatic growth would improve the depth of the theoretical model and improve overall understanding of the construct.

Public health campaigns might not be universally helpful and could have detrimental consequences. The current investigation explored the effects of obesity prevention campaigns. Their impact was assessed using an experiment in which participants were randomized to view either weight focused obesity prevention campaigns or obesity prevention campaigns that did not use weight related terms. Results demonstrated that compared with campaigns without weight related terminology, weight focused campaigns increased negative perceptions of obesity and decreased self-efficacy for health behavior change. No differences in body satisfaction, thin-ideal internalization, state anxiety, or frequency of positive health behaviors were found based on the type of campaign viewed. Finally, exposure to both types of campaigns increased internalization of the thin-ideal. This study demonstrates that weight focused prevention messages pose serious public health consequences. Obesity prevention campaigns should refrain from using weight-related terminology and instead emphasize the positive health consequences of a healthy diet and physical activity.

Background: Dietary supplements (DS) use has increased in the U.S. in the past 20 years. More than half of the U.S. population reported using DS. There are few studies to our knowledge that have assessed DS use specifically for older adults. In this study we purposed to evaluate the trend of using DS among older adults and to test the association between using DS and several demographics, socioeconomics and health characteristics. The second objective was to evaluate the reasons behind using DS among older adults using a nationally representative database. Methods: This is a cross sectional study using the most recent National Health and Nutrition Examination Survey (NHANES) database 2009-2012. It is a nationally representative sample of noninstitutionalized adults in the U.S. Frequency and weighted percentage (standard error) were reported for dichotomous variables. Multiple logistic regressions model analyses were used to evaluate the predictors of DS use after testing model assumptions, multicollinearity, and outliers. P values 0.05 were considered significant. All the statistical analyses were conducted using SAS software version 9.4. Results: Out of 2625 older adult participants (65 years and older) 70.5% of them reported using DS in the past 30 days. Female, non-hispanic white, obese, overweight and excellent and very good self-reported health status participants were more likely to use DS. Multivitamin-multiminerals (MVMM), calcium and vitamin D were the most commonly reported supplements among older adults. 71% of oldest old (80≥ years) reported taking DS and prescription medication in the past 30 days concomitantly and 73% of polypharmacy users reported using DS. To stay healthy, to improve overall health and for bone health were the most commonly reported reasons behind using DS. Conclusion: majority of older adult participants reported using DS in the past 30 days. Health care professionals need to evaluate the dietary supplement information from older adults in order to improve health care.

Hypertension is a preventable and yet major risk factor for early death and morbidity among African Americans. Compared to other women in the US, African American women continue to die earlier and more frequently from preventable and controllable chronic health conditions that are notably due to hypertension and hypertension-related illnesses. While there are multiple factors contributing to the high death rates of African American women, hypertension is one of the most common and modifiable risk factors associated with fatal health outcomes among African American women. The rate of death resulting from hypertension is more than double for African American females compared to white females. Even armed with increased knowledge and awareness, African American women are encountering barriers to controlling their hypertension, which places them at higher risk of becoming sicker and dying earlier than their white counterparts. The purpose of this mixed-methods study was to examine the effects of psychosocial stress on the hypertension self-management behaviors. The rationale for the study is supported by findings from a systematic literature review identifying gaps and contributions in the health literature on African American women and hypertension management. Findings underscore a need to continue to examine psychosocial factors as barriers to African American women’s hypertension self-management. Specifically, the study found statistically significant associations between psychosocial stress and depression as it relates to the hypertension self-management of African American women. Further investigation is warranted to better understand the significance of the relationships between psychosocial stress, depression and African American women’s hypertension self-management.

The purpose of this study was to investigate the preferred method of learning about heart disease by adult learners. This research study also investigated if there was a statistically significant difference between race/ethnicity, age, and gender of adult learners and their preferred method of learning preventative heart disease care. This research study further explored the effectiveness of adult education on reducing or preventing serious, life-threatening heart disease, including heart attack. This research is of significant importance as the adult population and age in many developed countries is increasing. It was anticipated that the study would unearth the effectiveness of various educational methods of providing information to adult learners to inform them how to prevent heart attacks. For this quantitative investigation, participants were limited to students enrolled in at least one college course (three credit hours) at the Florida Atlantic University Boca Raton campus who were 25 years of age or older. During the course of this study, three methods of learning; formal, informal, and non-formal, as well as two delivery methods; online and traditional, were evaluated. Over one third of the study’s participants (35%) preferred to receive healthrelated information via email (35%). This major finding was statistically significant (x² (6) = 82.171; p < .001). Further, statistically significant findings were manifest for study participants for omnibus age grouping and in the 25-35 years of age grouping, for those who were White and Hispanic by ethnic background, and for both females and males participating in this study. The results of this research may assist health department administrators in utilizing varying methods for distributing health information, keeping the preferred knowledge acquisition method of students on college and university campuses especially in mind. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Background: There are naturally occurring health events, such as illness diagnosis, that motivate people to spontaneously adopt healthy behaviours. Such events are often re-ferred to as teachable moments. They have the potential to increase the effectiveness of behaviour change interventions, when people are already motivated to change behaviour. However, it is unclear what makes illness diagnosis a teachable moment for some people but not for others. This project aims to identify the factors determining whether and for whom diagnosis of type 2 diabetes is a teachable moment, and to explore the components of a potential intervention to reduce the risk of type 2 diabetes among high-risk groups. Method: A mixed-methods design, divided into two studies, was employed. The first study was a qualitative study and used semi-structured interviews (n=10 patients and n=13 relatives). It explored the changes occurring in people after diagnosis of type 2 diabetes in oneself or a family member in an effort to identify what factors make diagnosis a teachable moment. The study also explored people's suggestions for a potential diabetes prevention intervention. The second study was a quantitative study and used postal questionnaires (n=85 patients and n=55 relatives). It investigated the relationship between potential teachable moment factors and primary outcomes (physical activity, diet, interest in diabe-tes-related information and education course). Results: This mixed-methods study suggests that the factors that may make diagnosis of type 2 diabetes a teachable moment for patients are outcome expectancy, perceived con-trol, severity, self-concept or social role, gender and time since diagnosis; and for relatives: perceived risk, severity, self-concept or social role, and gender. Although there was lack of complete alignment in factors identified through different methods, this study advances understanding of when interventions may be more (or less) successful. The study makes recommendations for potential interventions to capitalise on the teachable moment crite-ria. Conclusion: The current project highlights the complexity of teachable moment criteria and their relationship with behaviour change. Future research is required to further uncov-er these criteria and their utility for health promotion.

This study examines the relationship between exercise adherence and several factors: self-motivation; attitudinal commitment; predisposing, enabling, and reinforcing (PER) factors; and barriers related to exercise. The sample (N=431) consists of employees at Texas Instruments, Incorporated in Dallas, Texas. The sample was placed into six comparison groups: high adherers, low adherers, nonparticipants who exercise, nonparticipants who do not exercise, dropouts who exercise and dropouts who do not exercise. Using a one-way ANOVA, the results show significance (p<.01) among the groups for: self-motivation and barriers. Attitudinal commitment and PER factors did not show significance. The results can be applied to worksite health programs to increase exercise adherence among employee populations.
