  1. PA = Physical activity. Covariates: I = Intention, H = Habit (SRHI/SRBAI), PBC = Perceived behavioral control, A = Attitude, IA = Instrumental attitude, AA = Affective attitude, SN = Subjective norm, IS = Intention stability, IxIS = Intention x intention stability, D = (various) demographics, OB = engagement in (various) other behaviors. DG = Demographic: Gender. DA = Demographic: Age. Italicised references indicate papers based on same data but in which the focal moderation test was not reported.
