To assess the effectiveness of treatment in traumatology, different scales and assessment questionnaires are used. This work presents the results of the validity test of the two scales designed by the authors, namely, Moscow Foot Trauma Scale (MFTS) and Abbreviated Questionnaire of Subjective Assessment (AQSA). The study enrolled 79 patients (59 male and 20 female individuals with a mean age of 42) with multiple or concomitant foot fractures. For the scales, coefficients of reliability, stability, constancy, internal consistency (Cronbach’s alpha), split-half correlation (Guttman’s lambda) and intraclass correlation were calculated. SF-36 (Short Form 36) and AOFAS (American Orthopaedic Foot and Ankle Society Score) were used as reference scales. The study revealed a high reproducibility of the new scales: stability coefficient was 0.85–0.96 for MFTS and up to 0.93 for AQSA. Their reliability and internal consistency were established.
