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

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).

Validity evidence of the Brazilian version of the Perceived Motivational Climate in Sports Questionnaire-2 (PMCSQ-2BR).

In sports context, the motivational climate has been widely studied since 2000, when the Perceived Motivational Climate in Sports Questionnaire-2 (PMCSQ-2) was published. Evaluating athletes' perceptions of the motivational climate created by the coach, this questionnaire has been validated and adapted for different countries, including Brazil. However, important psychometric properties of the Brazilian version present problems, such as poor fit indices and the almost exclusively male samples, make it unfeasible for use in future research.

A Cross-Cultural Adaptation of the Collective Efficacy Questionnaire for Sports (CEQS): Validity Evidence for a Brazilian Version.

This three-part study aimed to translate, cross-culturally adapt, and validate the Collective Efficacy Questionnaire for Sports (CEQS) for Brazilian athletes. In Study 1, six translators and six specialists developed a Portuguese version of the CEQS (the CEQS-B), and 10 experts and 10 sports participants provided content validity evidence based on test content. In Study 2, 553 athletes completed the CEQS-B, and we provided evidence of construct and convergent validity for the test's internal structure through factor analysis and of reliability evidence based on the instrument's internal consistency and temporal stability.

Collective efficacy in soccer teams: a systematic review.

Collective efficacy, defined as a group's shared belief about its conjoint capability to organize and execute courses of action, plays a pivotal role in understanding the dynamics of sports teams, since it influences what individuals choose to do as team members, how much they invest in motivational terms to perform actions, how much they work collectively, and for how long they persist despite failure. Through a systematic review, it was investigated how collective efficacy has been assessed in the context of soccer and which indicators, attributes, and psychometric properties have been contemplated in the instruments used. Following the PRISMA guidelines, 22 articles were retrieved through electronic databases (APA PsycINFO; SPORTDiscus; Science Direct; BVS; Web of Science; Scopus; PubMed; and Scielo), using as descriptors, in English, Spanish, and Portuguese, collective efficacy and soccer, combined by the Boolean operators AND and OR.
