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). 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.

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. In Study 3, 79 athletes completed both the new CEQS-B and the Group Cohesion Questionnaire, and we provided evidence of concurrent validity for the CEQS-B, based on its relationship to other variables, with specific strong correlations between team task cohesion and collective efficacy among these participants. Overall, the results of this study support the use of the CEQS-B by researchers and professionals wishing to assess various sport athletes' self-perceived collective efficacy.

Self-efficacy in volleyball: What has been evaluated? A systematic review / Autoeficacia en voleibol: ¿Qué se ha evaluado? Una revisión sistemática / Autoeficácia no voleibol: O que se tem avaliado? Uma revisão sistemática

Self-efficacy in sport has been the purpose of study in different modalities, among them the volleyball. The aim of the study was to verify by means of a systematic review what has been evaluated volleyball self-efficacy. The databases APA, Bireme, Eric, Science Direct, Pubmed and Scopus were used to carry out the searches. After the research, the articles were selected, using the inclusion and exclusion criteria, resulting in 7 articles by the theme. The result points a absence of clarity in the instruments for assessing self-efficacy in volleyball with respect to what they intend to measure in relation to technical, tactical, physical or psychological attributes. In addition, few articles have pointed the psychometric properties of the instruments used in the research, which implies, in practical terms, inaccurate results, hindering the reproducibility of the studies. Therefore, it is suggested that specific instruments for the modality should be developed which present the statistical procedures used in order to obtain reliable results

La autoeficacia en el deporte ha sido motivo de estudio en diferentes modalidades, entre las que figura el voleibol. El objetivo del presente estudio fue realizar una revisión sistemática para conocer lo que se ha evaluado en los estudios sobre autoeficacia en voleibol. Las bases de datos utilizadas fueron APA PsycInfo, Bireme Eric, Science Direct, PubMed y Scopus. A partir de esta búsqueda, siguiendo los criterios de inclusión y exclusión se seleccionaron 7 artículos. Los resultados apuntan a la falta de claridad en los instrumentos de evaluación de la autoeficacia en el voleibol en lo referente a lo que pretenden medir de los atributos técnicos, tácticos, físicos o psicológicos. Además, pocos artículos indicaron las propiedades psicométricas de los instrumentos utilizados, lo que conduce, en términos prácticos, a resultados imprecisos. Se sugiere que se desarrollen instrumentos específicos para el voleibol y que en los artículos se presenten los procedimientos estadísticos utilizados
