Psychometric properties of the Burnout Inventory for Referees (BIR) for Brazilian Basketball Referees

Abstract

The main goal of this paper was to verify the psychometric properties of the Burnout Inventory for Referees (BIR) on Brazilian basketball referees. A total of 395 basketball referees were evaluated (age: 35.11 ± 9.18 years), of both gender (male = 319 and female = 76), with an average experience time of 12.34 ± 7.83 years, who answered demographic identification questionnaires, BIR and BRUMS. Factor validity was estimated using Confirmatory Factor Analysis (AFC) with the Maximum Likelihood estimation method. As homoscedasticity was rejected, the comparison between groups was performed using ANOVA with Welch's correction followed by the Games-Howell post-test. The correlation between the scores of the BIR-AB factors and the variables age and length of experience was assessed using Pearson's Correlation Analysis (r). The level of significance adopted was 5%. After the performance of the AFC and insertion of the second-order hierarchical model (MHSO), a new model was proposed, called BIR-AB (Burnout Inventory for Referees for Brazilian basketball referees), containing two negative dimensions (EFE and DES) and a positive (RE), with adequate adjustment indexes, acceptable and invariant reliability between the gender and in the test/validation sample and the divergent validity was attested.
