Moms in motion: a group-mediated cognitive-behavioral physical activity intervention.

Area of Science:

• Public Health
• Behavioral Science
• Exercise Science

Background:

• Women over 25, particularly after childbirth, face higher risks of physical inactivity.
• Existing postnatal exercise studies show benefits, but few interventions are theory-driven or tailored.
• Social-cognitive theory and group dynamics offer a framework for effective postnatal interventions.

Purpose of the Study:

• To compare a group-mediated cognitive behavioral intervention (GMCB) with standard exercise (SE) for postpartum women.
• To assess the impact of GMCB on physical activity levels and related psychological factors.
• To evaluate the efficacy of a theory-based, tailored intervention for postpartum exercise initiates.

Main Methods:

• Randomized two-arm trial with 57 postpartum women.
• Four-week intensive phase: standard exercise training (SE) plus GMCB (behavioral skills training, counseling).
• Four-week home-based phase: self-structured exercise; ANCOVA used for data analysis.

Main Results:

• Significant improvements in physical activity frequency, minutes, and volume for GMCB vs. SE (p < 0.01).
• GMCB participants showed increased barrier efficacy and outcome expectations, while SE participants decreased (p < 0.05).
• Both programs improved exercise participation, but GMCB yielded superior results.

Conclusions:

• GMCB is more effective than standard exercise in enhancing postpartum physical activity.
• The intervention positively impacts psychological factors like barrier efficacy and outcome expectations.
• Theory-driven, group-based cognitive behavioral approaches are beneficial for postnatal exercise interventions.
