Increasing Employees' Health by Workplace Physical Activity Counseling: The Mediating Role of Step-Based Physical Activity Behavior Change.

Background: This study evaluated the effects of a 3-month workplace physical activity (PA) intervention on employees' health-related fitness and well-being. Moreover, mediational pathways were examined.

Methods: A longitudinal, quasi-experimental trial was evaluated in Belgian employees.

Short- and long-term effectiveness of a three-month individualized need-supportive physical activity counseling intervention at the workplace.

Background: The objective of the present study was to evaluate the short- and long-term intervention and mediation effects of a 3-month individualized need-supportive physical activity (PA) counseling intervention on employees' PA and sedentary behavior.

Methods: Insufficiently active employees (n = 300; mean age 42 ± 9 years; 78% female) were recruited from a large pharmaceutical company in Flanders, Belgium. A quasi-experimental design was used in which the intervention group (N = 246) was recruited separately from the reference group (N = 54).

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).
