Spanish adaptation of the cutting movement assessment score (CMAS): Agreement and inter-rater reliability among Spanish-speaking football practitioners

Objectives

To translate and cross-culturally adapt the Cutting Movement Assessment Score (CMAS) screening tool, and to preliminarily explore its reliability among Spanish-speaking football practitioners.

Design

Translation and cross-cultural adaptation (phase 1) and cross-sectional reliability study (phase 2).

Setting

Following international guidelines, three sports injury experts produced an initial Spanish adaptation of CMAS (CMAS-Sp). This version was then back-translated into English, and the translations were compared to produce a final version CMAS-Sp.

Participants

Twenty-one sports practitioners, including 11 novices (<1 year of experience) and 10 experts (>5 years of experience), assessed four 90° cutting actions with the CMAS-Sp.

Main outcome measures

Factor analysis, internal consistency, inter-rater reliability and agreement.

Results

Factor analysis suggested a single factor explaining 52.3 % of the variance. Internal consistency was acceptable (Cronbach's α = 0.70; McDonald's ω = 0.79). Reliability of the total score was excellent (ICC (2, k) [95 % CI] = 0.94, [0.82, 1.00]). Item-level percentage agreement ranged from 55 % to 89 % with Gwet's AC1 values ranging from moderate-to-almost perfect.

Conclusion

The CMAS-Sp demonstrated acceptable agreement and good reliability for assessing cutting mechanics in Spanish-speaking practitioners, showing promise as an accessible screening tool pending further validation.
