Enhancing self-efficacy and exercise readiness in pregnant women

ObjectivesDespite the benefits associated with exercise during pregnancy, many expectant mothers are inactive.DesignThe present study examined whether persuasive messages could influence task and scheduling self-efficacy, exercise intention, action plans, and behavioral commitment among pregnant women.MethodsAfter completing premanipulation task and scheduling self-efficacy and exercise intention measures, participants (n = 125) were randomly assigned to read one of four efficacy-enhancing messages: scheduling, task, combined scheduling/task, or control. Postmanipulation task and scheduling self-efficacy, intentions and action plans and behavioral commitment were then assessed.ResultsRepeated-measures ANOVAs revealed that compared to the control group, inactive participants who read the persuasive messages reported significant increases in scheduling self-efficacy, task self-efficacy, and intention from premanipulation to postmanipulation as well significantly stronger action plans.ConclusionsWritten persuasive messages may promote exercise behavior during pregnancy by increasing scheduling and task self-efficacy, intention, and action plans for exercise.

► We examined the effects of persuasive messages on exercise self-efficacy.
► Scheduling and task self-efficacy increased after reading message.
►  Exercise intention increased in inactive pregnant women after reading message.
► Action plans were stronger among those who read the persuasive messages.
► Persuasive messages can be a first step in motivating exercise during pregnancy.
