Adherence
Walking group interventions delivered by lay people are as effective as those delivered by professionals.
You don't need a professional to lead your walking group. Lay people, with basic training, can effectively lead walking groups and achieve similar results to professional-led groups.
GoodSupportsHIGH confidence
Interventions delivered by a lay person had a similar effect size (d = 0.52, 95%CI from 0.25 to 0.79, n = 2843, k = 8, p < 0.0001) to interventions delivered by professionals (d = 0.51, 95%CI from 0.23 to 0.79, n = 1729, k = 11, p < 0.0001). The difference in effect size estimates was not statistically significant (z = 0.158, N = 4572, p = 0.43).
Why this rating
No statistically significant difference found, supporting the equivalence claim.
