Strengths and Limitations
The Vet-COACH trial has several strengths. First, intervention protocols were designed to be practical and feasible, thus allowing replication in other clinic settings. Second, we accounted for clustering by peer health coach. Largely ignored in peer health coaching studies is the peer health coach’s contribution to the intervention effect.This study also has several limitations. First, due to a variety of challenges, including the COVID-19 pandemic, the trial was underpowered to detect a difference in the primary outcome due to lower-than-projected sample size.
