This study explored: 1) the effects of an online messaging intervention on EPPM constructs and parental support for PA among families of CYID, and 2) parents’ perceptions of different messaging strategies. A four (time) x three (risk) x three (frame) repeated measures experimental design was employed. Parents of CYID (N = 80) received various combinations of risk information and framed PA messages, and completed online questionnaires. The risk information and framed PA messages evoked diverse message perceptions among participants. Additionally, decreases in EPPM constructs and parental support for PA observed over time, regardless of condition, suggested that participation in the study itself may have influenced these outcome variables.Author owns copyright, except where explicitly noted.
