How we are misinterpreting physical activity intention – behavior relations and what to do about it

Studies of the physical activity intention-behavior gap, and factors that may moderate the gap (e.g., habit, perceived behavioral control), can inform physical activity promotion efforts. Yet, these studies typically apply linear modeling procedures, and so conclusions rely on linearity and homoscedasticity assumptions, which may not hold. We modelled and plotted physical activity intention-behavior associations and the moderation effects of...
