The illicit use of prescription stimulants among college undergraduates is a prevalent and dangerous problem on college campuses across the United States. Though classified by the U. S. Drug Enforcement Agency as schedule II controlled substances (U.S. Department of Justice, 2008), undergraduates obtain these medications through peers and friends, and report misusing of these stimulants to aid their concentration and studying (DeSantis, Webb, & Noar, 2008). Because extant research concludes that the prevalence of the misuse of prescription stimulants (MPS) peaks among undergraduates, this research was guided by the Theory of Planned Behavior (Ajzen, 1985, 1991) as well as a memorable messages framework (Knapp, Stohl, & Reardon, 1981), and sought to examine the messages that college students recall about MPS, how those messages are associated with student’s intention to use stimulants directly, as well as indirectly through changes in attitudes, normative beliefs, and efficacy, and finally, to examine if receiving a memorable message predicts changes in intention to use, or actual use of stimulants over time. Data for the main study were collected in October 2014, and 137 undergraduate students reported a memorable message about MPS and were retained for analysis. Four weeks later, a follow-up survey was launched, and 89 undergraduates also completed the second survey. Results suggest that undergraduates do recall memorable messages about MPS, and the content focuses on the themes of academics, health outcomes, and responsible use. Additionally, memorable messages tended to be more negative than positive, and came from a variety of sources including close friends and peers, family members, instructors, and medical professionals, to name a few. Further, participants’ attitudes and normative beliefs were positively associated with behavioral intention at Time 1. Additionally, behavioral intention at Time 1 was positively associated with behavioral use at Time 2. The findings from this research provide several practical implications for future health education and promotion campaigns.

Native Americans start fewer businesses than do other U.S. populations, and the receipts and employment of those businesses are 70% lower than the U.S. average. However, little knowledge exists concerning Native American (NA) business success. The purpose of this quantitative study was to examine the likelihood that attitudes toward entrepreneurship, subjective norms, and perceived behavioral control predict business success amongst NA business owners. Understanding the factors that contribute to NA business success is imperative to developing best practices for business owners and business support agencies. The theory of planned behavior served as the theoretical framework for this study. Of the 550 invited NA business owners registered within a single tribe in the South Central United States, 79 participated in this study. A binary logistic regression analysis produced conflicting results: significant goodness-of-fit yet insignificant individual predictors. Information obtained from this study could assist NA and other underdeveloped business populations with understanding factors influencing entrepreneurial endeavors; however, readers must interpret findings with caution because of conflicting logistic regression results. NA business formation and success could enhance economic prosperity and decrease unemployment in NA communities.

The theory of planned behaviour proposes that behaviour is predicted by behavioural intention which is, in turn, predicted by attitudes toward the behaviour, subjective norms regarding the behaviour and perceived control over the behaviour. Implied within this theory is that each of the three base components (attitudes, subjective norms and perceived behavioural control) influences intentions. However, despite being one of the most widely used theories in social psychology, few studies have investigated this basic premise. In addition, research on cognitive dissonance, public commitment, confirmation bias, implemental mindset, and the false consensus effect suggest that there may be a reverse-causal influence of intentions back on the base components of the theory. This potential reverse-causal sequence was tested in three studies. The first was correlational, the second was a lab-based experiment, and the third was a quasi-experimental field study. Study 1 employed a cross-lagged correlation design and showed that a reciprocal relation between intentions and base components was plausible. For the behaviour of supporting an environmental organization, Study 1 showed that attitudes were likely to influence intention-setting and that intention-setting subsequently influenced subjective norms. Study 2 employed a modified version of a free choice paradigm in which participants chose to set an intention to support one of two environmental organizations (using different support behaviours). Consequently participants rated the base components for the chosen organization higher and the rejected organization lower. However, this effect was primarily observed if participants were not initially committed to supporting an organization before the study began. Study 3 was a field study in which chemistry lab users who were exposed to an intervention that targeted behavioural intentions subsequently perceived more positive subjective norms (one aspect of subjective norms was changed). Together, the three studies demonstrate that a reverse-causal relation between intentions and base components is plausible and, thus, the theory of planned behaviour should be modified to include a reciprocal relation between these constructs. Intentions are most likely to influence base components that are least relevant to actual behaviour. When attitudes, subjective norms or perceived behavioural control are associated with actual behaviour, the one that is most strongly associated is least likely to change in response to setting an intention to engage in that behaviour. Other, less relevant, base components are more likely to change. / Graduate / 0451 / 0621 / 0768

The purpose of this study was to use the Theory of Planned Behavior (TPB) to predict university students’ intention to use emergency contraception (EC). The study explored the utility of the TPB model constructs (attitude [A], subjective norm [SN], perceived behavioral control [PBC]) as well as recent past behavior (RPB) to predict students’ intention to utilize EC. The study also investigated the significance of demographic and personal characteristics—age and gender in particular—as they relate to the TPB components and RPB. A web-based survey, developed from three structured focus groups, was pretested and emailed to 2,000 university students. An overall usable response rate of 21.0 percent was obtained. In general, university students intended to use EC should the need occur, held favorable attitudes toward the use of EC, were somewhat influenced by social norms regarding EC use, and perceived themselves to have some control over EC utilization. For direct measures (TPB), A, SN, and PBC were significant predictors of intention to use EC. The direct model explained 49.2 percent of the variance in intention. Using indirect measures, A and SN were significant predictors of intention, but PBC was not; the indirect model accounted for 41.3 percent of the variance in intention to take EC. Attitude was the strongest TPB predictor for both models, followed by SN and PBC. The RPB variable did not significantly improve the TPB model. While hypothesized age differences were not significant, gender differences showed female students having a more favorable A and SN as well as a stronger PBC (direct measures) toward the use of EC. In addition, several statistically significant relationships occurred between demographic/personal characteristics and the TPB constructs. In summary, this study identified several key factors that partially explain why university students either intend or do not intend to use EC if needed. The TPB has utility in predicting utilization of EC in university students. Focusing particular attention on A, as well as SN and PBC, will allow researchers, educators, healthcare professionals, and legislators to develop strategies and educational programs to enable men and women to use EC responsibly. / text

The purpose of this longitudinal repeated measures experimental study was to determine the effects of bone health testing using dual energy X-ray absorptiometry (DXA) on outcomes of intentions toward and actual engagement in bone health behaviors (calcium intake, vitamin D intake, physical activity) among perimenopausal women. The Perimenopausal Bone Health Behaviors Model was developed based on the Theory of Planned Behavior and guided this study to determine how perimenopausal women respond to DXA and bone health information compared to bone health information only.One hundred fifty community-based perimenopausal women (ages 35-55) were randomly assigned to an intervention group (n=75 DXA and bone health information) or to a comparison group (n=75 bone health information). Baseline demographic data were collected. The Prevention Intentions Questionnaire and Behaviors Questionnaire were administered at baseline, at two weeks, and at two months after both groups received assigned interventions.Results showed 32% (n = 24) of intervention group women had low bone density. The intervention of DXA and bone health information showed near-significance (p = .068) over the intervention of bone health information alone in affecting women's intentions, and showed near-significance in affecting calcium intake (p = .052). Lower bone density test scores were related to higher intentions (r(74) = -.23, p = .046) at two weeks after DXA and bone health information, and were related to improved vitamin D intake (r(73) = -.25, p = .03) at two months after DXA and bone health information. At study end, Attitudes contributed 27.0% of the variance in Intentions among women who received DXA and bone health information; Attitudes, Subjective Norms, and Perceived Behavioral Control contributed 62.0% of the variance in Intentions among women who received bone health information only.Nursing interventions focusing on perimenopausal women should include providing bone health information to all perimenopausal women. Interventions targeting attitudes toward bone health behaviors may motivate some perimenopausal women to participate in behaviors that contribute to decreased risk of osteoporosis. Early detection and intervention in perimenopausal bone loss may reduce osteoporosis morbidity and may impact women's quality of life, reduce financial consequences to individuals, families, communities, and the nation.

The purpose of this study was to increase understanding of factors associated with nonmedical anabolic steroid use among males ages 18-30 who do not participate in intercollegiate athletics. The Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was developed, reviewed for content validity by a jury of experts, and pilot tested. The pilot testing results (n=25) demonstrated acceptable reliability (Cronbach’s alpha= 0.74). The final version of the Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was administered at two distribution sites which included Ford’s Fitness Center in Lexington, Kentucky and the Johnson Center on the University of Kentucky’s campus to non-intercollegiate athlete men between the ages of 18-30 (n=121). The final version of the survey instrument was also found to be reliable (Cronbach’s alpha= 0.86).Of the 121 respondents, 7 (5.9%) reported using nonmedical anabolic steroids at least 1-2 days a week or more. A total of 9 (7.4%) men reported intending to use nonmedical anabolic steroids within the next year. Age was found to have a statistically significant association with intention to use nonmedical anabolic steroids (p=.037).Perceived behavioral control (p=.029) was found to be the strongest predictor variable of study participants’ intention to use nonmedical anabolic steroids. Muscle mass builder use (p=.011) and muscle mass builder use in combination with multivitamin use (p=.000) were found to be significant predictors of actual nonmedical anabolic steroid use. Study participants were more likely to use nonmedical anabolic steroids if they were currently using a muscle mass builder or using a muscle mass builder in combination with a multivitamin. No decision about the effectiveness of the components of perceived behavioral control (self-efficacy and control) as a one or two part construct was possible because of the small number of study participants. Two additional demographic predictor variables were found to be statistically significant with predicting the intention to use nonmedical anabolic steroids. Being a competitive bodybuilder (p=.001) was positively correlated and being satisfied with body image (p=.025) was negatively correlated with the intention to use nonmedical anabolic steroids.

The implementation of a tobacco-free policy is the leading recommendation among health institutes for reducing the harms associated with tobacco exposure–for both smokers and nonsmokers–on college campuses. Despite the health benefits associated with tobacco-free policies, compliance with these policies remains a serious challenge on college campuses. Interventions aimed at increasing smokers’ willingness to comply with tobacco-free policies are essential for improving public health. Guided by the theory of planned behavior (TPB), the purpose of this study was to (a) investigate the factors associated with tobacco-free policy compliance among undergraduate students and (b) design and evaluate a theory-based campaign aimed at increasing compliance with a tobacco-free campus policy. To achieve these aims the current study was conducted in two phases. Phase One was a qualitative investigation that analyzed focus group data related to messaging strategies for increasing tobacco-free policy compliance. Phase Two was a quantitative investigation that used survey data to explore variables associated with tobacco-free policy compliance and to test the effectiveness of a campus-wide print-based campaign. Results from Phase One suggest various ways to target the TPB variables in messages in order to improve tobacco-free policy compliance. Results from Phase Two suggest the psychological variables and the physical variable of nicotine dependence are not related to tobacco-free policy compliance behaviors; however, social variables, quit attempts, and daily cigarette use are predictors of compliance behaviors. Similarly, the TPB variables had mixed results for relating to tobacco-free policy compliance behaviors. In addition, the campaign materials were supported as effectively improving tobacco-free policy compliance behaviors, both through individual level survey reports of compliance and observed compliance behaviors on campus. Although the campaign materials were designed around the TPB variables and were supported for improving compliance behaviors, above average campaign exposure was only found to improve normative beliefs from pre- to post-intervention. In addition to theoretical and practical implications offered from this study regarding tobacco-free policy compliance behaviors, this study also provides critical insight into the current compliance behaviors on the University of Kentucky’s campus.

Character education assumes responsibility for influencing and educating youth on morals, values, beliefs and positive character attributes in order to influence them into being positive and contributing members of society. Character education is most often taught in the home, schools and community. One community organization that integrates character education into its programming is 4-H Youth Development. The purpose of this research is to view the relationships between character education and 4-H, and more so whether Kentucky 4-H programs influence the knowledge, attitudes and practices of positive character among youth leaders. This study also looked at length of 4-H involvement and gender in order to determine influence. It was found that Kentucky 4-H programs do influence positive character among youth leaders, as youth indicated that they had gained character knowledge from 4-H involvement, as well as the program had made them a better person. It was also found that the gender of youth or their length of involvement in 4-H programs does not affect the character knowledge, attitudes and practices gained from involvement. The author recommends using these positive findings to continue to expand Kentucky programs and recruit adults and youth.

The Commonwealth of Kentucky is taking steps to expand bioenergy production in response to federal policy initiatives as well as environmental and energy security concerns. The success of this industry will be impacted by the supply of feedstock available from private individuals who own a majority (78%) of forest resources in the state. Despite a developing body of bioenergy research, little is known concerning the social availability of forest biomass for energy production. This study measures intent to harvest energy wood among family forest owners using a mail-­‐based survey and tests the effect of educational materials provided to participants. The theory of planned behavior is used to model factors that affect landowner intentions. Two-­‐thirds of respondents reported that they intend to include energy wood in future harvests, but the educational material treatment did not affect intentions. Respondents’ attitudes, perceived subjective norms, and perceived control each had a significant effect on intent to harvest. Respondents also identified barriers that may prevent them from harvesting, providing forestry professionals with a list of challenges to overcome if supply is to be maximized. The results of this study are valuable for all stakeholders involved in the development of a sustainable biomass and bioenergy industry.

Obesity is a widespread topic across the country as healthcare costs continue to rise. The field of health communication encompasses many efforts made by scholars and those working in health education and promotion to help individuals live healthier lives. As technology continues to evolve, e-health and mobile health programs are being explored as creative avenues for this endeavor. This study takes a mixed methods approach consisting of an experiment and a series of in-depth interviews. Based on the Theory of Planned Behavior, the experiment examines the effects of a popular mobile phone application, “my fitness pal,” on the users’ attitude, subjective norms and perceived behavioral control of health behaviors. The interviews investigate how and why the mobile application has health benefits. There were 35 University of Kentucky employees who participated, and then a few follow-up interviews were conducted. Although, several hypotheses were not supported by the data, the results show there was an increase in the overall health statuses of participants encouraged to interact with co-workers about the mobile application through social media as well as face-to-face communication. Several applications can be taken from this study in order to improve future mobile health applications and workplace health and wellness programs.
