The added value of a brief self-efficacy coaching on the effectiveness of a 12-week physical activity program . BACKGROUND Self-efficacy has been found to be an important precondition for behavioral change in sedentary people . The current study examined the effectiveness and added value of including a 15-minute self-efficacy coaching at the start of a 12-week lifestyle physical activity ( PA ) program . METHODS Participants were randomly assigned to a standard-intervention group ( without additional self-efficacy coaching , N = 116 ) or extra-intervention group ( with additional self-efficacy coaching , N = 111 ) . Body mass index ( BMI ) , cardiovascular fitness , self-reported PA , and self-efficacy beliefs were assessed at baseline and immediately after the intervention period . Perceived adherence to the PA program was assessed postintervention . RESULTS At posttest , a significant increase in cardiovascular fitness and decrease in BMI were found in both groups . Significant intervention effects emerged on PA behavior , self-efficacy , and program adherence , in favor of the extra-intervention group . Self-efficacy mediated the intervention effect on program adherence whereas no evidence was found for its role as mediator of PA change . CONCLUSIONS Adding a 15-minute self-efficacy coaching at the start of a lifestyle PA program is a promising strategy to enhance the intervention effects on PA behavior , self-efficacy beliefs , and program adherence . However , the role of self-efficacy as mediator of the intervention effect on in PA was not fully supported .
