TAN, Christine L.; GAN, Vincent B.; SALEEM, Fahad  and  HASSALI, Mohamed A.. Building intentions with the Theory of Planned Behaviour: the mediating role of knowledge and expectations in implementing new pharmaceutical services in Malaysia. Pharmacy Pract (Granada) [online]. 2016, vol.14, n.4, 850. ISSN 1886-3655.


Pharmacy value added services (PVAS) was introduced as a matter of public health policy by Malaysia’s Ministry of Health to improve health outcomes through public healthcare services. For example, drive through pharmacy services is a major policy implementation of the Ministry. However, adoption rates are low and therefore hampering the achievement of national health policy goals.


Our objective is to explore the key determinants and mediators of successful implementation of new public pharmaceutical services by investigating the cognitive perspectives of patients’ intentions to adopt with the Theory of Planned Behavior as the theoretical framework.


A two phase mixed methodology involving first a qualitative exploration and the second a quantitative phase was conducted in public health facilities in Negeri Sembilan, Malaysia. Multiple regression and mediation analysis were performed.


Subjective norms, perceived behavioural control, knowledge and expectations are found to be significant predictors of intentions to adopt PVAS. Knowledge and expectations are found to exert significant indirect effects on intentions.


Overall, we suggest that patient knowledge be enhanced through appropriate channels and expectations of service quality be met to increase intentions.
