Authors' conclusion
BCT-based interventions improve short-term daily PA in people with PAD/IC compared to non-SET controls. Evidence for maintenance of the improved PA at 6 months or longer and comparison with SET is uncertain.
Study context
- Population
- Individuals with PAD/intermittent claudication; study mean age 60.3 to 73.8, 29.5% female41 studies (26 RCTs, 15 non-RCTs)
- Participants
- 4,339 individuals
- Comparison
- Behavior-change technique (BCT)-based interventions vs any control

Maintenance of daily physical activity (PA) vs non-SET · ≥6 months
- Evidence of maintenance of daily PA unclear
- increase of 0.12 SMD 0.12 SMD (95%CI −0.04 to 0.29; ∼288 steps/day)
- 6 RCTs, 8 comparisons, 899 participants
- moderate certainty
Number of BCTs or BCT domain and PA
- Unclear whether the number of BCTs or any BCT domain was independently related to an increase in PA
