Psychometric properties of the group environmental questionnaire

Abstract

The study of group cohesion has great importance in the sport context, being able to reflect directly in the search for objectives and in the success in the competitions. In this way, there is the search for strategies that make it possible to measure cohesion, as in the case of the questionnaires, allowing to understand its relationship with performance. The aim of this study was to evaluate the psychometric properties of the Group Environment Questionnaire in junior football athletes. The psychometric properties were tested by means of Exploratory Factor Analysis (EFA), using Parallel Analysis (EFA), Confirmatory Factor Analysis (CFA), Item Response Theory (TRI) and reliability was assessed using two indicators: Cronbach's alpha and McDonald's Omega. Among the results, some indicators were found that adjustments and adaptations are required, such as scaling, as well as factors related to positive acquiescence and writing of some items. Therefore, some instabilities were found in the analysis of the psychometric properties, directing to the needs of adjustments that can guarantee greater precision of the instrument.
