Randomized Controlled Trial
Social cognitive mediators of the effect of the MobileMums intervention on physical activity.
To explore whether improvements in physical activity following the MobileMums intervention were mediated by changes in Social Cognitive Theory (SCT) constructs targeted in the intervention (barrier self efficacy, goal setting skills, outcome expectancy, social support, and perceived environmental opportunity for exercise). This paper also examined if the mediating constructs differed between initial (baseline to 6 weeks) and overall (baseline to 13 weeks) changes in physical activity. ⋯ Future interventions with postnatal women using SCT should target barrier self-efficacy and goal setting skills in order to increase physical activity.
