Numerous studies conducted in real-life have examined effect of different prioritisation states on physical activity participation.However, the majority of these studies do not discuss effects associated with equal prioritasation- a state that combines a strong intention to engage in physical activities and an equally strong interaction to engage in an alternative behaviour. This article discusses sensitivity of a number of statiscal models in detecting effects associated with equal prioritisation in physical activity contexts. Advantages and disadvantages associated with using different statistical models are also highlighted.
