Psychometric Support for a Brazilian Version of the Multidimensional Assessment of Teamwork in Sport (MATS-B).

ABSTRACT

In this study, we investigated psychometric support for a version of the Multidimensional Assessment of Teamwork in Sport (MATS) that would be suitable for Brazilian athletes. Four translators participated in the back-translation of this instrument from English to Portuguese, two specialists synthesized the Portuguese and English back-translation versions, and 10 experts assessed the questionnaire items and judged their content validity. To evaluate structural validity, we performed confirmatory factor analysis (CFA). We evaluated internal item reliability with a sample of 447 athletes who completed the adapted measure (the MATS-B). Finally, 202 other athletes completed both the MATS-B and a second measure of collective efficacy (CEQS-B) to provide external validity correlates. With these data, the MATS-B now provides valid and reliable data supporting its use with Brazilian athletes in an adapted assessment tool that aligns with the conceptual framework of teamwork in sports.
