Abstract: Introduction . Concussion, whose diagnosis is primarily based on clinical evaluation, is a pressing issue in modern sports. To improve diagnostic methods for concussion in high-performance sports, the Sport Concussion Assessment Tool (SCAT) protocol is used. However, as the original versions of this protocol are published in English, their application in other languages presents challenges in terms of cultural adaptation and linguistic nuances. Objective . To evaluate the comparability and equivalence of the three proposed Russian-language 10-word lists for memory assessment in athletes within the SCAT-5 protocol. Materials and methods . An examination of 446 athletes was conducted using the SCAT-5 protocol (373 males, 73 females; median age 37 [26; 43] years). Only athletes who showed no abnormalities during baseline (pre-competition) testing were included. The Russian-language version of the SCAT-5 protocol, featuring three different word lists for memory assessment, was prepared and adapted by specialists from the National Center of Sports Medicine of the Federal Medical and Biological Agency. Depending on the word list used to assess immediate memory, the athletes were divided into three groups. Evaluation metrics included the total number of symptoms, symptom severity score, immediate memory, and delayed recall. Statistical analysis was performed using IBM SPSS Statistics 23.0 software. Results . Comparison of the integrated immediate memory scores across groups revealed no statistically significant differences ( p > 0.05). Similarly, analysis of the integrated delayed recall scores showed no significant intergroup variations ( p > 0.05). A positive correlation was found between the integrated immediate memory and delayed recall scores in each group (Group 1: r = 0.629, p < 0.001; Group 2: r = 0.663, p < 0.001; Group 3: r = 0.591, p < 0.001). No correlations were observed between immediate memory and the total number of symptoms ( r = –0.011, p = 0.824) or symptom severity ( r = –0.015, p = 0.747). Conclusions . Each of the three proposed word lists demonstrated methodological validity comparable to the original English-language versions of SCAT protocols. These lists are interchangeable and are validated for use in the Russian-language versions of the SCAT-5, SCAT-6, and subsequent protocols where memory is assessed using 10-word sets. The implementation of this protocol enables more objective diagnosis and monitoring of athletes throughout various stages of post-concussion recovery.
