Subclaims¶

q3 i? Within the 5-10 station subgroup, OSCEs with station durations under 10 minutes achieved higher internal consistency (alpha = 0.88, 95% CI: 0.86-1.00) than those with durations of 10 or more minutes (alpha = 0.64, 95% CI: 0.59-0.69). → Peng Qiyun 2025

q3 · i? · quant-synthesis · r2

Subgroup meta-analysis restricted to studies with 5-10 stations, comparing duration <10 min versus >=10 min. The under-10-minute group reached the highest pooled alpha (0.88) in the review, attributed by the authors to reduced examiner and participant fatigue.

"when the station number were set to 5-10, internal consistency was significantly better with duration time under 10 min (Cronbach's alpha = 0.88, 95% CI: 0.86, 1.00) compared to durations exceeding 10 min per station (Cronbach's alpha = 0.64, 95% CI: 0.59, 0.69)."
