Predicting physicians intentions to prescribe statins using the theory of planned behavior Li et al 2017

The study conducted by Li et al. (2017) aimed to predict physicians' intentions to prescribe statins using the theory of planned behavior (TPB). The TPB is a widely used theoretical framework that explains human behavior by considering the attitudes, subjective norms, and perceived behavioral control of individuals.

The study was conducted in China, and the participants were 300 physicians who had experience in prescribing statins. The researchers used a self-administered questionnaire that included items related to the TPB constructs, such as attitudes, subjective norms, perceived behavioral control, and behavioral intentions.

The results of the study showed that the TPB constructs significantly predicted physicians' intentions to prescribe statins. Attitudes towards statin prescription, subjective norms, and perceived behavioral control were positively associated with behavioral intentions. Moreover, the study found that subjective norms had the strongest effect on physicians' intentions to prescribe statins.

The findings of this study have important implications for healthcare providers and policymakers in promoting the appropriate use of statins. The TPB can be used as a useful framework for developing interventions that target the attitudes, subjective norms, and perceived behavioral control of physicians to increase their intentions to prescribe statins. By doing so, the appropriate use of statins can be promoted, which can lead to improved patient outcomes and reduced healthcare costs
