The efficacy of a self-managed Acceptance and Commitment Therapy intervention DVD for physical activity initiation

Area of Science:

• Behavioral Psychology
• Health Promotion
• Exercise Science

Background:

• Initiating and maintaining physical activity is challenging due to inconvenience and discomfort.
• Effective interventions are needed to motivate individuals and minimize barriers to exercise.
• Self-managed, accessible interventions are desirable for widespread community implementation.

Purpose of the Study:

• To investigate the efficacy of a self-managed Acceptance and Commitment Therapy (ACT) intervention delivered via DVD for physical activity initiation.
• To assess if supplementing a walking program with an ACT DVD enhances physical activity levels.
• To determine the accessibility and convenience of a DVD-delivered ACT intervention.

Main Methods:

• Fifty-nine minimally active participants were randomized into two groups: a 12-week pedometer-based walking program alone, or the walking program with an accompanying ACT DVD.
• Primary outcome: overall physical activity level (assessed at baseline and post-intervention).
• Secondary outcome: pedometer-assessed step count (measured every 4 weeks).

Main Results:

• Participants receiving the ACT DVD showed significantly greater increases in physical activity post-intervention.
• The ACT DVD group was more likely to achieve program goals.
• Higher average step counts were reported in the ACT DVD group compared to the walking-only group.

Conclusions:

• A self-managed ACT DVD intervention is a simple, efficient, and accessible method for promoting short-term increases in physical activity.
• Supplementing a walking program with a self-managed ACT DVD effectively increases physical activity.
• Electronically delivered, self-managed ACT interventions show promise for physical activity promotion.
