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.

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.

OBJECTIVE: The Theory of Planned Behavior (TPB) and implementation intentions have been used effectively to explain and influence diet in middle-class, but not exclusively low SES populations. Furthermore, dietary research among low SES populations requires intake measures that are feasible and acceptable. Using three lines of research we evaluated 1) the utility of the TPB to explain fruit and vegetable (FV) intake, 2) efficacy, feasibility and acceptability of an implementation intention intervention to improve FV intake, and 3) agreement, feasibility, and acceptability of 2 dietary intake measures of FV intake in low SES women. DESIGN: Participants were adult female residents of Boston Public Housing. Study 1: Using a cross-sectional survey (n=144), we evaluated the utility of the TPB to explain FV intake. Study 2: We conducted a pilot randomized controlled implementation intention intervention to promote FV intake (n=20), and semi-structured interviews to evaluate feasibility and acceptability of the intervention (n=8). Study 3: We administered 2 24-hour recalls, a food frequency questionnaire (FFQ), and structured interviews (n=36) to determine agreement, feasibility and acceptability dietary intake measures. RESULTS: Study 1: The TPB construct perceived behavioral control significantly predicted intention to consume FV (OR=2.55,95%CI:1.23,5.27) and with BMI, FV intake (βPBC=0.37,t(1)=2.29,p=0.0235; βBMI= -0.02,t(1)= -2.41,p=0.0174; R2=.08,F[2,130]=5.72,p=0.0042). Study 2: Feasibility goals were met for retention and days to follow up, but not recruitment. Participants characterized the intervention as enjoyable. Limited hypothesis testing showed no significant increase in mean FV intake within (control (n=11):+0.50, 95% CI:-0.56,1.58 servings; intervention (n=9):+0.17, 95% CI:-0.85,1.20 servings) or between groups (control group +0.33, 95% CI:-1.06,1.73 servings). Study 3: Feasibility targets were met for contacts and retention, but not for enrollment. There was no significant association between 24-hr recall and FFQ measures for fruit (r=0.32, p=0.09) or vegetable (r=0.16, p=0.40) intake and no marked preference for method (35% FFQ; 31% 24-hour recall). CONCLUSION: The TPB may be useful to explain FV intake. Although acceptable, an implementation intention intervention may not be feasible or effective to influence FV intake. We demonstrated limited feasibility and association but generally equal preference between dietary measures of FV intake in low SES women.

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.

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.

Utilizing the theory of planned behavior, I examined the variables that affect Chinese individuals' help-seeking intention. A total of 251 Chinese individuals participated in this study. Results showed that the variables in the theory of planned behavior accounted for 16% of the variance in help-seeking intention. Specifically, attitude (r = .22, p < .001) and perceived behavioral control (r = .22, p < .001) were found to be significant predictors of help-seeking intention. Based on these results, mental health professionals can design outreach interventions, such as psychoeducational programs, to improve Chinese individuals' help-seeking attitude and perceived behavioral control in an attempt to increase mental health service utilization. Additionally, counselors can discuss with clients' their attitude and perceived behavioral control regarding seeking counseling in an attempt to assist clients in being committed to the counseling process.
