In the 21st century drug and alcohol abuse presents one of the most serious problems worldwide. Of particular concern is the strong relationship between drug use and crime. While law enforcement strategies, including incarceration, have been revealed to contribute little to break the vicious cycle of drug use and crime, substance abuse treatment has been shown to represent an effective form of intervention. Substantial research on the effectiveness of drug treatment has demonstrated the importance of motivation in predicting treatment retention and success. However, substance users are frequently coerced into therapy by external sources, including the criminal justice system, therefore, typically exhibiting little motivation to enter and remain in treatment long enough to overcome their substance addiction. Although past research investigating the effects of treatment-entry coercion indicates positive treatment results, the vast majority of these studies are seriously impeded by extensive conceptual and methodological problems, questioning the postulated value of coercion in substance abuse treatment. Following the call for a shift in the methodological focus of future studies made by some researchers, the author of the present study tested three models that were based on well-established theories. The first model was based on Self Determination Theory (SDT), a motivational theory, while the second model was based on the Theory of Planned Behaviour (TPB), an expectancy-value theory. The third model consisted of a combination of the two theories, which was argued to provide a more complete and comprehensive model than each theory on its own. The testing of the models allowed the exploration of the dynamic interplay and relationships between a number of variables including perceptions of coercion, motivation, perceived autonomy support, and behavioural intentions in an effort to explain and predict retention and treatment outcomes amongst drug and alcohol abusers. The study was conducted in two phases. Phase 1 involved the development of a 29-item instrument called the Perceived Coercion Questionnaire, which was designed to assess participants' perceptions of coercion to enter drug and alcohol treatment originating from six different sources. The scale was shown to be a valid and reliable measure of the coercion construct. Phase 2 involved the testing of the three models longitudinally by using a sample of 350 substance abusers from six therapeutic communities across Australia. Participants were asked to complete a battery of standardised measures within the first two weeks of treatment admission (Time 1), two months into treatment (Time 2), and at completion of the treatment program (Time 3). The models were tested cross-sectionally and longitudinally employing hierarchical multiple regression analysis. In addition, change scores were calculated to test whether changes in predictor variables would predict outcomes and changes in outcomes cross-sectionally and longitudinally. Analyses of Time 1 and Time 2 cross-sectional data revealed that the SDT model, compared to the TPB and the combined model, provided a better and more parsimonious account of the factors that influence outcomes in therapeutic community treatment. Given the complexity of the study, it was decided to resume the analysis by focusing on the investigation of the SDT model alone. To highlight some of the most important findings, results demonstrated that motivation was a key factor in the treatment and rehabilitation of substance users. As anticipated, intrinsic motivation was consistently predictive of retention and more positive treatment outcomes, while external motivation and amotivation were associated with more negative outcomes. Results also revealed that clients who entered treatment as the result of a legal mandate experienced substantially higher levels of legal coercion compared to clients who entered treatment voluntarily. Legal coercion, in turn, was found to exert a negative impact on substance users' motivation for treatment, thereby indirectly resulting in more negative treatment outcomes. In contrast, self coercion (i.e., feelings of pain and suffering) and health-related pressures seemed to facilitate the development of a more intrinsic motivational attitude towards treatment. Besides, perceptions of competence and control in relation to the therapeutic regime emerged as consistent and important predictors of motivation and treatment outcomes. Finally, findings suggested that treatment staff who employed more autonomous and non-coercive strategies that guided substance users through the change process directly influenced individuals' treatment motivation and thereby facilitated more positive treatment outcomes. In sum, findings provided support for the usefulness of the SDT model in predicting dropout as well as processes and outcomes in therapeutic community drug and alcohol treatment. Implications for residential substance abuse treatment were discussed, as well as the strengths and limitations of the study. The discussion concludes with implications for practice and suggestions for future research.

The time from onset of a cardiac arrest to defibrillation is crucial hence access to and use of a defibrillator by all nurses essential. The purpose of this study was to use an established theoretical framework to examine and describe the defibrillation practices and beliefs of rural registered nurses in the Australian state of Queensland. The Theory of Reasoned Action (TRA) and Theory of Planned Behaviour (TPB) guided the research processes for this two phase study. In the first phase, focus group (n = 13) discussions identified the salient beliefs of the population. By eliciting nurses' beliefs, the subsequent quantitative study (n = 434) was conducted to determine the influences of these beliefs on nurses' use or non-use of defibrillators. The results showed that: (1) less than half of the cohort of participants were permitted to defibrillate; (2) the defibrillation beliefs of those nurses permitted to defibrillate were significantly more positive than those not permitted to do so; (3) the direct measures of TPB and selected variables external to the model predicted a significant portion of the variance in the measure of nurse-initiated defibrillation intention; and, (4) subjective norm emerged as the strongest predictor of intention. In conclusion, Queensland rural hospital nurses and employers still have some distance to travel down the path of nurse-initiated defibrillation. The TPB is a viable framework on which to base interventions designed to promote defibrillation by rural nurses. Understanding the role of social norms is of central importance to ensure all nurses can initiate the chain of survival expeditiously whenever the need arises.

This study investigates the factors that influence appropriate use of audit support systems. Appropriate use is use of an audit support system in a manner consistent with how the audit firm expects the system to be used. Investigating appropriate use of audit support systems is important because the extent to which these systems can assist auditors achieve efficient and high quality audits depends on how auditors use them. Adaptive Structuration Theory (AST) (DeSanctis and Poole, 1994) and the Theory of Planned Behaviour (TPB) (Ajzen, 1991) are combined to model the relationship between constructs hypothesised to increase the probability that audit support systems are used appropriately. The theoretical model decomposes two TPB antecedents, perceived normative pressure (or subjective norms) and perceived behavioural control, into the exogenous constructs hypothesised to influence whether audit support systems are used appropriately. Perceived normative pressure is decomposed into two socio-ideological control mechanisms, team and firm consensus on appropriation. Perceived behavioural control is decomposed into self-efficacy and two technocratic control mechanisms, perceived system restrictiveness and perceived audit review effectiveness.

<p>The purpose of this thesis was to increase the understanding of Swedish consumers’ attitudes and purchase intentions of functional food for marketers by using the Theory of Planned Behavior (TPB). It was discovered that previous research conducted in Sweden concerning functional food centered largely on motivational factors for adoption, and perception of the health claims made by these products; however there was a lack in research concerning purchase intentions and a use of theory to evaluate both attitudes and purchase intentions.</p><p>Both qualitative and quantitative research methodology were utilized in this thesis. The qualitative research data consisted of 14 short interviews designed to elicit beliefs about purchasing functional food. The quantitative research data was gathered using a questionnaire specifically designed for the Theory of Planned Behavior (TPB). A total of 257 responses were received from students, employees, and members of the general public.</p><p>The results from the questionnaire revealed that Swedish consumers had slightly positive attitudes towards purchasing functional food and neutral intentions to purchase functional food. The results from the interviews revealed that amongst other things, Swedish consumers believed that functional foods provide beneficial health benefits, but they are quite expensive. Doctors and family were viewed as important when considering the purchase of functional food. And price and knowledge were viewed as controlling factors of whether or not these foods were purchased.</p><p>The results provided by this thesis will be helpful to marketers of functional food as they plan marketing related activities aimed at Swedish consumers</p>

<p>Every year many people all over the world are killed and severely injured in road traffic accidents. Even though driving too fast is a behaviour well known to contribute to both the number and the outcome of these accidents, drivers are still speeding. The general aim of this thesis, and its five empirical studies, is therefore to further the knowledge about drivers speeding behaviour by using the theory of planned behaviour and the model underpinning the driver behaviour questionnaire as frames of reference. The behavioural data used is obtained from field trials with intelligent speed adaptation and the speed reducing potential of this system is also examined. The results show that attitude towards exceeding the speed limits, subjective norm, perceived behavioural control and moral norm from the theory of planned behaviour, but also violations and inattention errors from the model underpinning the driver behaviour questionnaire, can be used to predict drivers’ everyday speeding behaviour. These two models can also be combined in order to gain further knowledge about the causes of speeding. Identification of drivers’ beliefs about exceeding the speed limits gives further insight into the underlying cognitive foundation of their attitude, subjective norm and perceived behavioural control. This provides valuable information for future design of speed reducing measures. Regarding intelligent speed adaptation, the results show that the ISA speed-warning device greatly reduces the amount of time drivers spend above the speed limits, and to some extent also reduces their mean speeds, but that this effect decreases with time. Although the drivers are not totally satisfied with the experience of the ISA speed-warning device, they like the idea and can see its usefulness. As the device tested is a first generation ISA speed-warning device, further research has the potential to greatly improve the system.</p>

A key role of public relations is to manage crises, unexpected yet unpredictable events that cause emotional and physical harm (Coombs, 2007). Among the challenges in handling a crisis effectively is dealing with the various media in which information is presented. Because the use of social media in a crisis is a relatively new phenomenon, further understanding of the challenges and opportunities of these media is warranted. Part of meeting this challenge requires precise modeling of consumer responses to safety messages. To remedy gaps in our understanding of social media and food safety crisis communications, consumer intent to comply with a food safety message was evaluated within the framework of the Theory of Planned Behavior (TPB; Ajzen, 1991). Superimposed on the TPB intention model were possible moderator variables of message source (professional versus user-generated) and message reliability (confirmed versus unconfirmed information). Three focus groups provided background for the construction of a research instrument according to guidelines specified by Francis, Eccles, Johnston, Walker, Foy, et al. (2004). A 2x2 experimental design with four scenarios (message source x reliability), and realism checks of the scenarios were conducted. A pilot test with 130 undergraduate university students preceded administration of the instrument to a representative U.S. consumer panel of 400 participants. Results indicated that intent to comply with a food safety message was higher in response to messages in professional sources than in user-generated sources, but that the majority of this effect could be explained by participant age, which in turn predicted use of social media. Message reliability did not affect intent to comply—confirmed and unconfirmed messages had similar effects on intent to comply. All aspects of the TPB were confirmed by the current results with the exception of perceived behavioral control, which was so consistently strong that it was unable to predict variations in intent to comply with a food safety message. Consequently, the current data support the Theory of Reasoned Action (TRA; Fishbein & Ajzen, 1975) rather than the TPB. Implications of the results for public relations and crisis communications, limitations of the study, and recommendations for future research are discussed.

The study examines the phenomenon of purchasing locally produced foods in retail grocery stores. Theoretical foundations from the theory of planned behavior and from the stimulus-organism-response framework were used to support and test a model that hypothesized relationships between attitude, subjective norms, perceived consumer effectiveness, perceived product availability, intention to purchase, store atmospheric responsiveness, price consciousness, and extent of purchase behavior in a retail grocery setting. An online survey methodology was used to collect 600 responses across the United States. A two-step approach to structural equation modeling was used to test the relationships. Confirmatory factor analysis with measurement model development supported the hypotheses of store atmospheric responsiveness as a multidimensional construct reflected in four specific dimensions (1) product assortment responsiveness, (2) display factors responsiveness, (3) customer service responsiveness, and (4) store promotions responsiveness. The construct of perceived consumer effectiveness (PCE) was found to highly correlate with attitude and PCE was subsequently dropped as an independent latent construct. Results from analysis of the fitted structural model indicated that attitude and perceived product availability were significant positive indicators of intention to purchase, while subjective norms indicated a significant negative relationship to intention to purchase. A significant positive direct effect between intention to purchase and extent of purchase and a significant positive indirect effect through that of store atmospheric responsiveness was found, suggesting that store atmospheric responsiveness partially mediates the relationship. Consumer price consciousness was found to not significantly moderate the relationship between intention to purchase and extent of purchase. From the results, academic and managerial implications were suggested. For future research directions, four distinct categories emerged; they included (1) a focus on store atmospherics, specifically store atmospheric responsiveness when shopping for locally produced foods, (2) analysis of group differences between shoppers of locally produced foods, (3) category analysis of locally produced food items, and (4) research on the pricing of locally produced foods.

Efforts to reduce the United States’ dependence on foreign petroleum encourage the production of fuels from bioenergy crops. Recent energy mandates have therefore “opened doors” for alternative feedstock sources for ethanol production. Switchgrass is a candidate feedstock. Under the University of Tennessee’s Biofuels Initiative, the University of Tennessee, partnering with DuPont-Danisco Cellulosic Ethanol LLC, contracted for the production of switchgrass with local farmers to guarantee biomass feedstock supply for an ethanol conversion research facility. This study used methods borrowed from the social psychology literature in combination with economic theory to analyze factors influencing switchgrass farmers’ intentions to continue growing switchgrass after contracts with the granting agent expired. Understanding what motivates producers to make long term commitments to switchgrass production as an energy crop may be important information for private investors who will rely on a fixed supply of switchgrass. A probit model was used to determine the factors affecting producers’ intentions to continue producing switchgrass after their contract expires. Results suggest that community perceptions about the production of switchgrass as a dedicated energy crop may have an important impact on farmers’ intentions to make a long-term commitment to produce switchgrass. Therefore, educating and involving community and extension personnel may have a positive impact on farmers’ decisions to make long-term commitments to grow switchgrass as a dedicated energy crop.

Several aspects contribute to road crashes and one important part is the ‘human factor’. This information is interesting but insufficient unless we also try to understand what is meant by the term. Three different features have been defined: errors, lapses and violations and the latter, which is a deliberate act, has been found to be the main contributor to road crashes. The crucial issue is therefore to understand what motivates drivers to commit an act, which puts both themselves and others at risk. The aim of this thesis is to explore the motives behind this behaviour through the use of an extended version of the theory of planned behaviour (TPB). Four different studies were carried out: The first study is qualitative, investigating the intention to violate. The second one assesses speeding in an urban area and dangerous overtaking. In addition to variables within the model, descriptive norms and past behaviour are included. The third study explores what particular beliefs are responsible for the behaviour. The fourth study uses the TPB to predict intention to speed on a rural road and assesses some underlying factors, such as ambivalence and gender. The results of the thesis show that the theory explains 33 to 53% of the variance in intention to violate and that descriptive norm and past behaviour significantly increase the explained variance. Descriptive norm is also related to risk and past behaviour is not only related to intention but also to the variables within the model. The results show that drivers’ beliefs can distinguish between intenders and non-intenders. With regard to attitudes the general conclusion is that the main difference lay in the effect of positive outcomes. Although in a more ‘risky’ situation the behaviour is more controlled by a denial of negative consequences. Finally, the results indicates that in the context of driving violations an expressed low level of control over the behaviour could be interpreted as a form of denial of responsibility rather than an inability to control their own actions. Implications of the current findings for the development of intervention programmes are discussed.
