Psychometric Evaluation of the Team Identification Scale among Greek Sport Fans: A Cross-validation Approach

The aim of the present study was to explore the multidimensional nature of sport team identification. More specifically, the study tested the psychometric properties of the Team Identification Scale (TIS) among Greek sport fans using a cross-validation approach. Following a thorough procedure, the TIS was initially translated and then validated using a sample of 327 Greek sport fans. Item meaning equivalence was also examined using a sample of 257 Australian sport fans. Results presented evidence regarding TIS's reliability, factorial validity, predictive efficacy and cross-national generalizability. It seems that the TIS is a valid tool for assessing the multidimensional nature of this construct among both English- and Greek-speaking populations.
