A feasibility randomized controlled trial of a multi-process action control web-based intervention that targets physical activity in mothers

ABSTRACT

The onset of motherhood is associated with a decline in moderate- to vigorous-physical activity (MVPA) and this deficit can remain for years to come. This study explored the feasibility of a web-based intervention, informed by the multi-process action control (M-PAC) framework, to promote PA in mothers. Forty-one inactive mothers of children <16 were randomized to a 10-week web-intervention (n = 20) or wait-list control (n = 21). Primary outcomes of recruitment and retention were measured with frequency counts; usability and satisfaction were measured via self-report questionnaires and qualitative interviews; secondary outcomes of MVPA and M-PAC constructs were assessed via self-report. Recruitment was 41%, retention was 88%, and satisfaction and usability were high. Participants logged in 7.94 (SD = 3.87) times and spent 37.71 (SD = 20.21) minutes per week on the web-intervention. Suggestions for intervention improvement included additional content targeting mothers, reminders, and optimized navigation. Intervention participants trended toward improved MVPA and M-PAC constructs, particularly action control processes of habit, self-identity, and behavioral regulation. The high feasibility ratings of recruitment, retention, satisfaction, and usability demonstrated that the study can be extended to a full-scale RCT with minor additions to the intervention such as content targeting mothers, reminders, and optimized navigation.
