To measure goal perspective in sport, reflected by Achievement Goal Theory (3), Duda & Nicholls (7) devel- oped the Task and Ego Orientation in Sport Questionnaire (TEOSQ), that comprises 13 items to assess athletes disposi- tional goal orientations. However, the Portuguese version of TEOSQp, was validated in several contexts of sport: young football players (4), sport athletes, recreational exercisers and physical education students (5), and physical education stu- dents (6). So, the main purpose of this study is to assess the factorial validity of TEOSQp and confirm the two factors model structure in a football referees population. This propose was accomplished using confirmatory factorial analysis (CFA) procedures, with data from a sample composed by 200 Portuguese football referees (155 main referees; 45 assis- tant referees), from different categories (69 first category; 131 third category). Adopting the criteria proposed by Hu & Bentler (9), the results of CFA only provided support for two-factor structure and showed an reasonable model fit to the data with a 11-items model (�� =67.42; df=43; p=0.01; �� /df=1.56; SRMR=0.063; CFI=0.955; RMSEA=0.053; RMSEA 90%IC=0.026-0.077). This model also show acceptable reliability in Cronbach's alphas for both factors (ego=.82; task=.74). These findings lead us to the elimination of item 9 and 12. However, good factor validity and reliability charac- teristics of the TEOSQp was obtain with the 11-items model. Nevertheless, perhaps some caution is needed in interpreting these results and more studies are advisable to a strong adaptation of TEOSQp to football referees.
