BACKGROUND Pragmatic trials of implementation interventions focus on evaluating whether an intervention changes professional behaviour under real-world conditions rather than investigating the mechanism through which change occurs. Theory-based process evaluations conducted alongside pragmatic randomised trials address this by assessing whether the intervention changes theoretical constructs pr...

Using the Theory of Planned Behaviour (TPB), this study investigates weight control in overweight and obese participants (27 kg/m(2)≤BMI<45 kg/m(2)) taking part in a dietary intervention trial targeted at weight loss maintenance (n=932). Respondents completed TPB measures investigating "weight gain prevention" at three time points. Correlation and regression analyses were used to investigate th...

AIMS A randomized controlled trial was used to evaluate a brief research-based intervention designed to promote drinking within recommended limits on Fridays and Saturdays among moderate drinkers. METHODS The two-page, leaflet-like intervention included persuasive communication targeting motivational and volitional antecedents of behaviour as specified by an extended theory of planned behavio...

Chronic obstructive pulmonary disease (COPD), diabetes and asthma are chronic illnesses that affect a substantial number of people. The continued high cost of clinic- and hospital-based care provision in these areas could be reduced by patients self-monitoring their condition more effectively. Such a move requires an understanding of how to predict self-monitoring compliance. Ajzen's theory of ...

INTRODUCTION The implementation of complex medical interventions in daily practice is often fraught with difficulties. According to the iterative phase model proposed by the British Medical Research Council (MRC), the development, implementation and evaluation of complex interventions should be theory-driven. A conceptual model that seems to be a promising framework is the Theory of planned beh...

The aim of this study is to examine the determinants of fruit and vegetable (F&V) consumption with the application of the Theory of Planned Behaviour (TPB) and the additional variables of self-schema, habit and self-regulation. While it has been shown that those with a healthy-eater self-schema are more likely to carry out their healthy dietary intentions, the underlying processes that influenc...

The present study sought to test the efficacy of a brief theory-based intervention to promote regular consumption of breakfast, and to expand previous results suggesting that the theory of planned behaviour (TPB) can be meaningfully applied to breakfast consumption. A four-armed randomised controlled trial was conducted. Participants (n=349) were allocated to receive either a (1) positively fra...

objectives: limited studies have demonstrated that the theory of  planned behavior (tpb) may be able to help in explaining the variation in physicians’ behavior. we selected the management of asthma as the tracer topic because asthma had nationally known clinical guidelines, and the main medicinal therapies used for asthma had limited applications for the treatment of  other diseases, and hence...

The purpose of this study is (1) to examine Australian university students’ awareness of the benefits of Web 2.0 technologies and (2) to investigate the factors that influence students to adopt Web 2.0 technologies to supplement in-class learning, using the theoretical foundations of both Theory of Planned Behaviour (TPB) and Decomposed Theory of Planned Behaviour (DTPB). Findings indicated tha...

BACKGROUND Psychological models are used to understand and predict behaviour in a wide range of settings, but have not been consistently applied to health professional behaviours, and the contribution of differing theories is not clear. This study explored the usefulness of a range of models to predict an evidence-based behaviour -- the placing of fissure sealants. METHODS Measures were colle...
