Abstract
The Group Environment Questionnaire (GEQ) is an instrument developed to study cohesion in sport teams. The main aim of this study was to verify conceptual validity of the Czech version of Group Environment Questionnaire by method of structural equation modelling.
As participants in this study served 1169 athletes (848 men and 321 women). For the data analysis we utilised exploratory and confirmatory factor analysis approach.
The original model was tested to confirm the structural theory and diagnosis quality of this tool. Results of the original 4-factor model demonstrated poor fit and unaveradge values of RMSEA 0.086 and CFI 0.894, TLI 0.874 and lack coefficients of generic reliability.
After reanalysing our data we established a modified Bi-factor structure of GEQ without five original inicators. The Bi-factor model with general factor at IA-T, GI-T and separate factors IA-S and GI-S shown the best values of fit RMSEA 0.056, CFI 0.981 and TLI 0.965.
