Resource and visitor experience degradation in Haleakalā National Park resulting from recreational use of the Pools of 'Ohe'o has led park officials to discourage visitor use of the pools. This study uses the Theory of Planned Behavior (TPB) to examine relationships among visitors' attitudes, subjective norms, and perceived behavioral control with regard to exploring the pools, their intentions to explore, and their actual behaviors while visiting the pools. Further, this study examines the influence of persuasive messages on visitors' behavior at the pools. Persuasive message treatments emphasize either the dangers of exploring the Pools of 'Ohe'o or resource protection and visitor experience impacts of recreational use at the pools. Through regression analysis of attitudes, norms, and perceived behavioral control with intention to explore, TPB is generally found to be an effective model for understanding visitor behavior at 'Ohe'o's Pools, particularly when visitors are exposed to persuasive messages. Results of analysis of variance indicate that the TPB model components of attitudes and subjective norms with regard to traveling companions and National Park Service officials are influenced by exposure to the persuasive treatment messages. Additionally, both intention to explore the pools and observed exploration behavior are significantly lower among those visitors receiving any persuasive treatment message. Thus, results of this research generally support the individual relationships assumed within TPB. With identification of the most influential components of visitor behavior, as understood through the TPB model developed in this study, managers of Haleakalā National Park will be able to develop and apply persuasive interpretive messages that maximize safe and sensitive visitor recreational behavior at the Pools of 'Ohe'o. / Master of Science

Breast cancer affects thousands of women each year and among those diagnosed, African-American women (AAW) make up a significant proportion that are diagnosed with early onset disease, have larger tumors, greater lymph node involvement, higher mortality and lower survival rates. Studies examining factors associated with greater breast cancer morbidity and mortality in this group have suggested that they may differ from Caucasian women in terms of certain risk factors for breast cancer; however, other evidence suggests that the risk of developing breast cancer is similar among African-American and Caucasian women who have a family history of breast cancer. As such, access to genetic counseling and testing (GC/T) services would be an important part of cancer control for this group but in this fast moving area of medicine African-American women are being "left behind". It is unclear why AAW have not readily adopted these preventive services. In light of the paucity of evidence regarding explanations of underuse, it is possible that important factors such as perceived behavioral control (PBC) in the Theory of Planned Behavior may help explain African-American women's participation in genetic counseling and testing for BRCA 1/2. The goals of this mixed methods study were twofold; first, to explore levels of perceived behavioral control and general motivations regarding genetic counseling and testing for BRCA 1/2 in African-American women at moderate to high-risk for breast and ovarian cancer and second, to explore the dimensionality of the perceived behavioral control construct from the Theory of Planned Behavior (TPB) and its utility in understanding underuse of BRCA 1/2 genetics services in this group. African-American women are being "left behind". Overall, women had high levels of perceived behavioral control, low knowledge and positive attitudes towards genetic counseling and testing for BRCA 1/2. Results from the principal components analysis lent support for the dimensionality of the perceived behavioral control construct suggesting that it indeed could be thought of as made up of the constructs perceived control [P-C] and perceived difficulty [P-D]. Only perceived control was found to be associated with genetic testing intentions suggesting that it was a better predictor. Neither scale was associated with genetic counseling intentions. African-American women are being "left behind". Future research should focus on educational efforts geared towards highlighting the utility of genetic counseling in addition to genetic testing for BRCA 1/2. Theoretical implications include using two measures to assess aspects of perceived behavioral control (perceived difficulty [P-D] and perceived control [P-C]) instead of one PBC measure. Additionally, studies using the TPB model should include the constructs of spirituality and knowledge when trying to understand underuse of BRCA 1/2 genetic services in African-American women at moderate to high-risk for breast cancer. African-American women are being "left behind". / Ph. D.

Sensory and consumer sciences aim to understand the influences of product acceptability and purchase decisions. The food industry measures product acceptability through hedonic testing but often does not assess implicit or qualitative response. Incorporation of qualitative research and automated facial expression analysis (AFEA) may supplement hedonic acceptability testing to provide product insights. The purpose of this research was to assess the application of AFEA and qualitative analysis to understand consumer experience and response. In two studies, AFEA was applied to elucidate consumers emotional response to dairy (n=42) and water (n=46) beverages. For dairy, unflavored milk (x=6.6±1.8) and vanilla syrup flavored milk (x=5.9±2.2) (p>0.05) were acceptably rated (1=dislike extremely; 9=like extremely) while salty flavored milk (x=2.3±1.3) was least acceptable (p<0.05). Vanilla syrup flavored milk generated emotions with surprised intermittently present over time (10 sec) (p<0.025) compared to unflavored milk. Salty flavored milk created an intense disgust response among other emotions compared to unflavored milk (p<0.025). Using a bitter solutions model in water, an inverse relationship existed with acceptability as bitter intensity increased (rs=-0.90; p<0.0001). Facial expressions characterized as disgust and happy emotion increased in duration as bitter intensity increased while neutral remained similar across bitter intensities compared to the control (p<0.025). In a mixed methods analysis to enumerate microbial populations, assess water quality, and qualitatively gain consumer insights regarding water fountains and water filling stations, results inferred that water quality differences did not exist between water fountains and water filling stations (metals, pH, chlorine, and microbial) (p>0.05). However, the exterior of water fountains were microbially (8.8 CFU/cm^2) and visually cleaner than filling stations (10.4x10^3 CFU/cm^2) (p<0.05). Qualitative analysis contradicted quantitative findings as participants preferred water filling stations because they felt they were cleaner and delivered higher quality water. Lastly, The Theory of Planned Behavior was able to assist in understanding undergraduates' reusable water bottle behavior and revealed 11 categories (attitudes n=6; subjective norms n=2; perceived behavioral control n=2; intentions n=1). Collectively, the use of AFEA and qualitative analysis provided additional insight to consumer-product interaction and acceptability; however, additional research should include improving the sensitivity of AFEA to consumer product evaluation. / Ph.

The purpose of this sequential exploratory mixed methods study was to develop and test a theory of planned behavior questionnaire that includes both direct and belief-based measures for seeking professional help from a MFT for participants and their spouses during times of relationship distress. To complete this goal, three focus groups (N = 24) were conducted to elicit the salient behavioral, normative, and control beliefs associated with seeking professional help from a MFT for participants and their spouses during times of relationship distress. The data was member checked and then analyzed using thematic analysis. Next, two quantitative measures were constructed, one using the salient beliefs elicited during the focus groups and the second using general questions that assessed participants' overall attitude, perceived norm, and perceived behavioral control. Both measures were placed online pilot tested (N = 102) using Qualtrics panels. The results suggest that the measures were accurate predictors of behavioral intention. The main stage then used both measures to assess the predictive ability of the elicited beliefs. The results also suggest that the beliefs accurately predicted participants' behavioral intentions for seeking professional help from a MFT for them and their spouses during times of relationship distress. The results also indicate that an intervention could be used to encourage troubled individuals, couples, and families to seek professional help from a MFT when experiencing relational issues. / Ph.

Interest in wood-based bio-energy systems in the United States is increasing and may play a part in future renewable energy initiatives (Dincer 2000). Family forests have potential to play an important role in supplying wood biomass for energy production. However, access depends mostly on the management intentions among family forest owners. Enhanced biomass markets in regions where family forest ownership dominates could increase productivity by reinvigorating the low-value merchandizing required to accomplish silvicultural objectives. Given diverse owner objectives and forest types on family forests, estimates of biomass availability must include both biophysical and social aspects of procurable feedstock. This thesis chronicles a biosocial case study that estimates potential biomass supply from 51 family forests in Virginia and North Carolina. The study occurred within a woodshed centered on the future site of an impending ethanol plant in Mecklenburg County, Virginia. A survey instrument using the theory of planned behavior was used to measure ownership characteristics and intention to harvest. Forest attributes were collected during property visits to estimate potential yields resulting from silvicultural simulations. Results reveal that forest cover-type and tree size significantly affect owner intentions to harvest and owner attitudes toward harvesting partially mediate this relationship. Outputs from silvicultural simulations correspond with those made using Forest Inventory and Analysis data within the study region. Disproportionality was examined by coupling social and biological drivers of sustainable wood biomass availability. Implications of the research include refined estimates of potential supply and demonstrating a multi-scalar, mixed-method approach for assessing wood biomass availability. / Master of Science

Evaluation is a burgeoning field and remains fairly young by most standards. Within Cooperative Extension, evaluation practices have been implemented at a variety of levels given that evaluation is mandatory for much of the funding Cooperative Extension receives. With evaluation in high demand, it is expected that most Extension educators are performing some levels of evaluation as a routine part of their jobs. In order to perform the required evaluations, an Extension educator must exhibit some level of knowledge and skill regarding evaluation. While much research to date has been done on the level of evaluation within the organization, there is a lack of understanding regarding the evaluation competencies that Extension educators must possess and the culture of evaluation within the organization. This study set out to examine the evaluation competencies, culture, and evaluation behaviors within Cooperative Extension. Utilizing an online survey format and quantitative methodology, a widely accepted set of evaluation competencies were examined for their importance within Cooperative Extension. A panel of 13 experts was selected to examine the competencies and it was determined than all competencies in the list were necessary for Extension educators to exhibit in their jobs. The list of competencies was then combined with a subscale regarding culture and a subscale based on the Theory of Planned Behavior (Ajzen, 1991). A total of 419 Extension educators in four Extension systems participated in the study, with 222 generating usable data for a response rate of 13%. The highest and lowest skill level for the competencies were determined by Extension educators self-reporting. Perception of importance of each competency was examined and the highest and lowest importance rankings were determined. These were compared to the rankings of importance by the expert panel. A path analysis was conducted by modifying the Theory of Planned Behavior model and multiple regression analysis. Mean weighted discrepancy scores were calculated to determine the differences in skill level and perception for each of the competencies. The subscale of culture was examined for potential areas of Evaluation Capacity Building (ECB) within the organization. Results show that while there was much agreement between the expert panel and Extension educators regarding the importance of competencies, experts ranked all competencies as important while Extension educators did not. The results of the path analysis determined intention and perceived behavioral control explained 3.9% of the variance in the evaluation behavior exhibited by skill. Subjective norm and attitude explained 11.8% of the variance within intention. Perceived behavioral control, attitude and culture accounted for 13.1% of the variance in subjective norm. Culture and perception accounted for 7.1% of the variance in attitude. Perception, program area, college major, location, training in evaluation, degree level and years of experience explained 28% of the variance within evaluation culture. Finally, recommendations for practice and future research were made based on these findings. / Ph. D.

No / In light of the growing interest in "ethically questionable" consumer behavior, this study explores possible explanations of the occurrence of such behaviour, and subsequently develops a theoretical framework. The study is based upon data collected from 72 U.K. consumers, acquired from a projective approach with scenarios. Taking the theory of planned behavior (TPB) as an initial analytical framework, attitude, social influence, opportunity (as perceived behavioral control in TPB) and perceived unfairness are identified as the antecedents of ethically questionable behavior (EQB). Social influence is extended to include a broader range of external influences from subjective norm in TPB. Opportunity is considered to represent an aspect of perceived behavioral control as available resource to engage in EQB. Perceived unfairness is presented as an additional component and refers to the extent to which an actor is motivated to redress an imbalance that is perceived as unfair. Binary logistic models suggest that attitude and social influence consistently impact on EQB, as TPB would predict. Analysis of variance suggests that perceived unfairness and opportunity, though context specific, also show signs of significant influence on the acceptance and practice of this behavior. Additional to the construct of TPB, this study develops the dimension of perceived unfairness in the context of EQB decision-making. In the context of TPB, it provides further insight into our understanding of EQB, helping to provide a theoretical framework.

This study is a novel application of I/O Psychology principles to the U.S. swine industry. The Swine Health Information Center (SHIC) recently identified caretaker motivation related to compliance with biosecurity behaviors as a priority needing to be better understood. This exploratory study seeks to identify if there is indeed a worker motivation issue within the industry that is impacting compliance with biosecurity, and if so, establish both a baseline of motivation and a better understanding of the primary influencing factors. Using the Theory of Planned Behavior and the Job Demands/Resources Model of Burnout as a framework, an online survey was developed using items, adapted or in original form, from previous research and established measures. A total of 139 caretakers from five pork production companies participated in the survey and form the study's sample population. Results suggest the swine industry's problem with biosecurity compliance is not a motivationally driven issue, but findings were unable to provide evidence supporting a conclusive determination. Results for attitude (TPB) and job resources (JD-R) suggest further investigation into the rewards, supervisor support, and performance feedback categories of job resources could be promising avenues for continuing to explore what drives biosecurity non-compliance. Valuable insight was obtained about the swine industry and the caretaker role, and results are promising for improving quality of data collected as the research continues applying I/O theories and models to the swine industry for the purpose of investigating worker resources and attitudes. Continuing this research will help one of the largest industries in the United States to better understand the interactions and motivations behind worker attitudes and perceptions towards biosecurity adherence and to enhance positive outcomes for employees, farms, and consumers.

Yes / Rationale: The Reasoned Action Approach (RAA) developed out of the Theory of Reasoned Action and Theory of Planned Behavior but has not yet been widely applied to understanding health behaviors. The present research employed the RAA in a prospective design to test predictions of intention and action for groups of protection and risk behaviors separately in the same sample. Objective: To test the RAA for health protection and risk behaviors. Method: Measures of RAA components plus past behavior were taken in relation to eight protection and six risk behaviors in 385 adults. Self-reported behavior was assessed one month later. Results: Multi-level modelling showed instrumental attitude, experiential attitude, descriptive norms, capacity and past behavior were significant positive predictors of intentions to engage in protection or risk behaviors. Injunctive norms were only significant predictors of intention in protection behaviors. Autonomy was a significant positive predictor of intentions in protection behaviors and a negative predictor in risk behaviors (the latter relationship became non-significant when controlling for past behavior). Multi-level modelling showed that intention, capacity, and past behavior were significant positive predictors of action for both protection and risk behaviors. Experiential attitude and descriptive norm were additional significant positive predictors of risk behaviors. Conclusion: The RAA has utility in predicting both protection and risk health behaviors although the power of predictors may vary across these types of health behavior. / Data collection for this research was funded by a grant from the British Academy to the first three authors.

Yes / Background: Reasoned action approach (RAA) includes subcomponents of attitude (experiential/instrumental), perceived norm (injunctive/descriptive), and perceived behavioral control (capacity/autonomy) to predict intention and behavior. Purpose: To provide a meta-analysis of the RAA for health behaviors focusing on comparing the pairs of RAA subcomponents and differences between health protection and health-risk behaviors. Methods: The present research reports a meta-analysis of correlational tests of RAA subcomponents, examination of moderators, and combined effects of subcomponents on intention and behavior. Regressions were used to predict intention and behavior based on data from studies measuring all variables. Results: Capacity and experiential attitude had large, and other constructs had small-medium-sized correlations with intention; all constructs except autonomy were significant independent predictors of intention in regressions. Intention, capacity, and experiential attitude had medium-large, and other constructs had small-medium-sized correlations with behavior; intention, capacity, experiential attitude, and descriptive norm were significant independent predictors of behavior in regressions. Conclusions: The RAA subcomponents have utility in predicting and understanding health behaviors.
