Note. In all BCTs, Control n = 10 Intervention n = 18, except question “If I have not reached my PA goal I have considered what went wrong”, where intervention n = 17 (participant indicated having reached their PA goal). The corresponding BCT is specified in parenthesis (numbering refers to BCT Taxonomy v1, Michie et al., 2013,)
