Three studies were conducted to examine the role of psychosocial factors in the prediction of health innovation uptake. A health innovation is a device, treatment or altered food product intended to improve the health of an individual or group and considered new by the population of interest. Health innovations may be used to address current health problems in individuals but also play a key role in preventative health efforts. Encouraging individuals to adopt appropriate health innovations is often an important strategy in improving the general health and minimising the social cost of illness of a population. The current program of research examined the influence of predictors from the Theory of Planned Behaviour (TPB; Ajzen, 1991), the Technology Acceptance Model (TAM; Davis, 1989; Davis, Bagozzi, & Warshaw, 1989), and risk technology literature (Fischhoff, Slovic, Lichtenstein, Read, & Combs, 1978; Slovic, 1987; Slovic, Fischhoff, & Lichtenstein, 1980) on health innovation decision-making. Additionally, the study examined the background factors of previous experience with the innovation, age, and gender. Guided by the overall conceptualisations of change presented in the Stages of Change Model (Prochaska & DiClemente, 1984; Prochaska & Velicer, 1997) and the Innovation Decision Model (Rogers, 1958, 2003), the three studies aimed to examine the role of the proposed predictors for a number of different innovations at various stages of diffusion. Study 1 (N = 358) employed a correlational design to predict people's intentions and willingness to use the four health innovations of functional foods, vitamin supplements, alternative therapies and pedometers. Participants completed questionnaires based on the TPB examining attitude (favourability towards the innovation), subjective norms (pressure from others for innovation uptake) and perceived behavioural control (PBC; sense of control over adopting the innovation). In addition, participants completed items assessing the constructs of usefulness of the innovation and ease of use of the innovation from the TAM and familiarity of risks and dread of risks associated with the innovation, adapted from the risk literature. Background factors, such as previous innovation use and age and gender of the participants, were also examined. The underlying behavioural, normative, and control belief constructs of the TPB were examined to differentiate between those participants who reported that they were intending to or willing to adopt the health innovation and those who were not intending to or willing to adopt the health innovation. Overall, the results of Study 1 supported the TPB constructs, perceived usefulness from the TAM, and risk familiarity. Study 2 (N = 102) utilized an experimental design where usefulness of the four innovations examined in Study 1 and the familiarity of risks associated with them were manipulated in a 2 x 2 scenario based study. As in Study 1, participants completed measures of the TPB factors, an assessment of the dread of risk and reported background factors such as previous innovation use, and their age and gender. Participants read reports of 'recent research' that contained information about the innovations' usefulness in relation to health benefit and familiarity of risk in comparison to traditional health products. As in Study 1, people's intentions and willingness to use the health innovations were examined, as was a third outcome measure; participant predicted future use of each innovation. The results of Study 2 provided support for the TPB constructs of attitude and subjective norms. The study also provided limited support for the TAM factor of usefulness, as well as for the risk dimensions of familiarity of risks and dread of risks. The TPB construct of PBC and the background factors of age and gender were not supported. Study 3 (N = 116) employed a 2 x 2 between-subjects design where usefulness and dread of risks were manipulated for a previously unavailable health innovation, calcium enriched mints. Study 3 also involved a within-subjects measurement of two behaviour measures (estimated consumption, and a diary recorded measure of consumption) over three time periods. Intention was retained as a third uptake measure of innovation uptake. Participants were presented with manipulated information about the usefulness and dread of risks associated with calcium enriched mints. Study 3 examined the role of the manipulated constructs, the TPB factors, familiarity of risk, and demographics in the prediction of the enriched mints uptake. The design of this study addressed limitations identified in the literature and mirrored a number of authentic health innovation uptake situations. The results of Study 3 strongly supported the role of attitude and subjective norms as influential predictors of intention to consume the calcium enriched mints, and intention as a predictor of estimated and diary recorded measures of consumption. The study offered limited support for the risk factors of familiarity of risks and dread of risks and did not support the TAM construct of usefulness as a predictor of calcium enriched mint uptake. Taken together, the results of this research provided strong support for the role of the TPB factors of attitude and subjective norms, but not PBC, as predictors of health innovation intentions and willingness. The results also supported the role of intention as a predictor of health innovation adoption behaviour. Limited support was found for the risk dimensions of familiarity of risks and dread of risks, suggesting that another conceptualisation of risk may be more appropriate for health innovation decision-making. The results found little support for the TAM variables of usefulness and ease of use, or the influence of demographic characteristics of age and gender. These findings indicate that the general decision-making model of the TPB, with the exception of the role of PBC, provides a useful framework to understand people's health innovation decision-making. Given the limited support for PBC in the prediction of intentions and behaviour in this context, the Theory of Reasoned Action (Fishbein & Ajzen, 1975), with some consideration of risk factors, may be an appropriate approach to adopt to facilitate an understanding the factors underlying people's decision to use innovations designed to improve their health.

Adult students (n = 211) from a Private Training Establishment located in a low socio-economic area of Counties Manukau, New Zealand, were assessed for intent to achieve and actual outcome. Each year in New Zealand approximately 25% of students leaving school do so with no qualifications. It is estimated that in the Counties Manukau Region there are 77,000 adults with no educational qualifications, impacting on earning ability and on self-esteem. Failure rate at tertiary education is high, with 38% of under 18 year olds not achieving, and this figure worsens with age. The cost to New Zealand of having people not in employment, not in education and not in training is estimated to be close to $1.0 billion per year and in Counties Manukau the cost of youth unemployment is between $55 and $73 million per annum. This study applied The Theory of Planned Behaviour to assess intent to achieve, and was expanded to include a self-esteem component (Rosenberg’s Self-Esteem Scale, 1965). The Theory of Planned Behaviour sufficiently predicted intent, and was significantly improved with the self-esteem component. The Rosenberg Self-Esteem Scale successfully predicted outcome, however findings need to be interpreted with caution. The initial self-esteem levels (M=20.59), whilst just above the accepted criteria (M=20.00) validate other studies indicating that New Zealand has an over-all low level of self-esteem compared with other similar countries. These findings indicate opportunity for future research into the prediction of outcome and ability of learning establishments to mitigate risk of non-achievement for the adult learner. They also support the further investigation of the low level of self-esteem as evidenced in this study.

Magister Artium - MA / The aim of the study was focused on investigating how Web 2.0 technologies are being utilised by students and lecturers to accomplish their learning and teaching activities in the Faculty of Information Science and Communications (ISC) at Mzuzu University in Malawi. The study answers the following specific research questions: • What is the current awareness of and familiarity with Web 2.0 technologies amongst students and lecturers in the Faculty of ISC? • For what educational purpose do students and lecturers in the Faculty of ISC use Web 2.0 technologies and which Web 2.0 technologies do they use most? • What do lecturers in the Faculty of ISC perceive as benefits of integrating Web 2.0 technologies in teaching and learning? • What are the factors that influence students and lecturers in the Faculty of ISC to adopt Web 2.0 technologies? The study adopted the Decomposed Theory of Planned Behaviour (DTPB) by Taylor and Todd (1995) which explains the rejection and acceptance of technological innovations such as Web 2.0. The researcher adopted a case study design in which both qualitative and quantitative data were collected to answer the research problem. The study was conducted in three phases; in phase one, a questionnaire was sent to 186 students and 19 lecturers, phase two involved analysing the curricula and phase three involved conducting follow-up interviews with seven lecturers to seek clarification on some concepts and elaboration on themes identified in phases one and two. The findings show that between 69 (50.7%) and 128 (94.1%) students use these Web 2.0 technologies to search for information, to communicate with lecturers, to submit assignments, to communicate with friends on academic work and to share content with fellow students. Most lecturers use these technologies in handing out assignments to students, receiving feedback from students, uploading lecture notes, searching for content, storing lecture notes and carrying out collaborative educational activities. Between 66 (45.8%) and 95 (69.9%) students use Wikipedia, WhatsApp, Google Apps and YouTube and similarly, between 10 (58.8%) and 13 (76.5%) lecturers use Wikipedia, YouTube, Blog, Google Apps and Twitter to accomplish various academic activities. The findings show further that attitude (perceived usefulness, ease of use and compatibility) and perceived behaviour control (self-efficacy, resource facilitating condition and technology facilitating condition) are strong DTPB factors that determine students’ and lecturers’ intention to integrate Web 2.0 technologies in their academic activities. On the other hand, lack of Internet access remains the recurrent key stumbling blocks towards a successful adoption of Web 2.0 technologies in learning and teaching at Mzuzu University (MZUNI). Generally, the study reveals that Web 2.0 and a compendium of Internet technologies have proliferated at Mzuzu University in the Faculty of ISC. Both students and lecturers are aware, to some extent, of the benefits of integrating Web 2.0 in teaching and learning. The researcher has made three main recommendations which include the need for the Faculty of ISC to introduce awareness and training programmes on the new technologies so that students and lecturers are kept up-to-date about the new developments about these technologies, the need for the newly established Directorate of ICT at MZUNI to promote the use of Web 2.0 technologies by conducting work workshops and sourcing funds for students and lecturers to participate in local and international conferences on Web 2.0 and finally, the need for Mzuzu University to install campus–wide Wi-Fi so that students and lecturers can seamlessly access the Internet on every point of the campus using mobile phones or laptops.

The Canadian C-Spine (CS) and CT-Head (CT) Rules are tools aimed at improving the accuracy and efficiency of radiography use in emergency departments. This study evaluated whether the Theory of Planned Behaviour (TPB) could explain the inconsistent results from implementation studies of these two rules at 12 Canadian hospitals, where the same intervention resulted in a significant reduction in CS radiography but not CT radiography. It was demonstrated that the TPB model’s proposed relationships between constructs and behaviour could explain the ordering of CS but not CT radiography. However, after examining longitudinal changes of the TPB constructs, it was clear that these changes could not explain the changes in CS radiography ordering. Overall, TPB is unlikely to suggest important ways by which to improve radiography use, for CT because its constructs are not related to radiography ordering, and for CS because of high baseline levels of intention to clinically clear.

Despite the growing need for depression prevention programming for university students, few programs exist and those that do are too resource-intensive for broad dissemination. Furthermore, limited research has been conducted on mechanisms of change in CBT-based prevention programs and similar research conducted on CBT for depression demonstrates mixed findings. Therefore, there is a need to incorporate a formal model of health-behaviour change in prevention (and intervention) programs to clarify mechanisms of change and improve outcomes, such as the theory of planned behaviour (TPB). This series of studies developed and tested a formal CBT-TPB “hybrid” model to predict intention to change thinking patterns and a brief depression prevention program for university students and to examine the program’s potential to change the hypothesized constructs in the hybrid model. Results indicated support for the hybrid model, in that TPB factors predict intention to change thinking patterns. In addition, across an open and randomized control trial, my “Start Making a Change” intervention promotes change in TPB factors, as well as improvement in relevant CBT and well-being outcomes. The implication of this work is that brief, easy-to-disseminate, programs, based on a formal model of change, can effectively, at least in the short term, target and change important risk factors for depression onset in university students.

This research was conducted to provide insights into the factors that influence consumer’s decision when choosing a channel to remit. The study looked at the following theories in determining the important factors that influence consumer intention or behavior, Theory of Reason Action, Theory of Planned Action, Remittance, Innovation Diffusion and Technology Acceptance Models. Hence, service providers should be aware of these factors so they can develop strategies and services to attract consumers to use their channels. The aim of the study was to determine which factors influence consumer’s decision in choosing a bank and non-bank channel to remit. The investigation of the key factors that influence the decision or intention, it was found that a single factor influenced the decision to remit in a bank and non-bank channel. It was also found in the study that consumers prefer physical channel of both bank and non-bank to remit. The finding has serious implications for service providers, in that consumer behavior show attachment to traditional distribution channels. / Dissertation (MBA)--University of Pretoria, 2011. / Gordon Institute of Business Science (GIBS) / unrestricted

After looking in the vault copies, the Digitization Centre has determined that page vi is a missing page and may be a printing error. -Digitization Centre / This study aimed to improve understanding of walking exercise among individuals with intermittent claudication. Using a prospective design, Ajzen's (1985, 1991) theory of planned behaviour was applied to examine psychosocial determinants of walking exercise. In addition, measures of barrier self-efficacy were explored as determinants of behaviour and perceived pain intensity was examined as a moderator of the intention-behaviour relationship. Ninety-four participants (n = 33 female) completed baseline measures of attitudes, subjective norms, perceived behavioural control, and intentions to engage in walking exercise. Additional measures of pain-related barrier self-efficacy and barrier self-efficacy regarding walking exercise were obtained and the Borg CR1 0 Pain Scale (Borg, 1998) was used to assess perceived pain intensity during walking. Participants were contacted weekly by telephone over four consecutive weeks and asked to recall their walking exercise and associated perceived pain intensity for the preceding seven-day period. Attitudes, subjective norms and perceived behavioural control contributed significantly to a multiple regression model predicting 67% of the variance in walking intentions. Intentions and perceived behavioural control explained 34% of the variance in walking exercise; however, pain-related barrier self-efficacy and barrier self-efficacy did not explain additional variance in behaviour and perceived pain intensity failed to moderate the intention-behaviour relationship. Findings support the theory of planned behaviour for predicting walking intentions and exercise among individuals with intermittent claudication, and suggest that pain cognitions as measured in this study do not play a role in determining walking. / Thesis / Master of Science (MS)

Yes / Based on an empirical investigation in the context of Romania, this paper identifies a moderating role of neutralization techniques within ethically questionable consumer behavior. The quantitative study is based upon a synthesized model of Theory of Planned Behavior incorporating the factor of perceived unfairness and neutralization techniques. Significantly, neutralization techniques are shown to have a negative, but definite impact on the action to behave unethically. This leads to their consideration as a process of thinking, rather than as static judgement. As such, neutralization techniques are conceptually distinctive to the other factors. The paper analyses the results specific to the Romanian context, but noting implications for an understanding of the morality of markets with similar historical, political and economic conditions. Overall, the findings offer a more nuanced reading of consumer behavior. The paper places moral flexibility in terms of a specific cultural context, but also reveals how neutralization techniques can moderate ethically questionable behaviors beyond matters of self-interest, which in turn has implications for how companies can consider their responsibilities in relation to their customers.

Yes / Being obese or gaining excessive weight during pregnancy can increase health risks for mother and baby. Adopting a healthy diet and increasing physical activity reduces these risks and has long-term health benefits for women. Despite this, women do not always maintain a healthy lifestyle during pregnancy. Aim To explore the factors that encouraged and prevented a diverse group of women to maintain a healthy lifestyle during pregnancy. Methods A total of 12 women participated in semi-structured qualitative interviews, underpinned by the theory of planned behaviour. Interviews were audio recorded, transcribed verbatim then subject to deductive thematic analysis. Findings Four themes emerged: women's knowledge of a healthy lifestyle, sociocultural influences, physical health and health professional support. These influenced women's intentions and actual behaviours during pregnancy. Conclusions Enhanced health professional advice may motivate women to adopt a healthy lifestyle during pregnancy. This could be through new means such as health technology.
