Subclaims¶

q3 i3 Subgroup analysis comparing validated versus unspecified coaching models found no significant difference in final performance scores (SMD 0.46, p = 0.13) but significantly higher mean change scores for validated models (SMD 1.06, p < 0.0001). → Anderson Steven Mark 2025

q3 · i3 · quant-synthesis · r3

Subgroup meta-analysis comparing validated coaching models (e.g., GROW, modified PRACTICE) against unspecified models. Final scores were not significantly higher (SMD 0.46, p = 0.13), while change scores were significantly higher with an effect size of SMD 1.06 (95% CI 0.43, 1.68).

"A further subgroup analysis was performed comparing the use of a previously validated coaching model for participants receiving VBC did not result in significantly higher mean final performance scores (SMD 0.46, 95% CI −0.13, 1.05, Z = 1.53, p = 0.13, and Supporting Information S1: Figure S3), though significantly higher mean change scores were seen (SMD 1.06, 95% CI 0.43, 1.68, Z = 3.32, and p < 0.0001"
