q3 i? Among 23 included studies, Cronbach's alpha ranged from 0.43 to 0.93; 11 studies achieved good internal consistency (alpha >= 0.8) while 15 did not (alpha 0.43-0.79). → Peng Qiyun 2025

Descriptive synthesis of all 26 alpha values from 23 studies. The wide range (0.43-0.93) and the finding that 15 of 23 studies fell below the good-reliability threshold motivated the subgroup analyses by station number and duration.

"Among the 23 studies analyzed, Cronbach's alpha values ranged from 0.43 to 0.93 (Fig. 2). 11 studies demonstrated good internal consistency (Cronbach's alpha >= 0.8), while 15 studies did not reach the good standard (Cronbach's alpha falling between 0.43 and 0.79)."

Discussion¶

Related Claims¶

• OSCE designs with 5-10 stations achieve good internal consistency (Cronbach's alpha = 0.83), outperforming designs with fewer than 5 or more than 10 stations — related
• When station number varies widely, duration time per station is not a major factor affecting OSCE internal consistency — related
• A six-station sport medicine OSCE showed high reliability and construct validity, with senior residents outscoring junior residents — a narrower finding that bears on this claim
• OSCEs used with physical therapy students show weak internal consistency, with a pooled Cronbach's alpha of 0.55 below the acceptable range — a narrower finding that bears on this claim
