L’auto-efficacia è un predittore della prestazione arbitrale nel calcio

The aim of the study is to evaluate if self-efficacy predicts football officials' performance, judged by outside observers. Participants: At the beginning of the football championship season 216 Italian football's officials (mean age = 19.38, d.s. 1.9) completed a 13-item specifically scale for officiating. Procedure: Participants have been followed for one year by outside observers who rated several aspects of their performance. Specifically, athletic, technical, behavioural and disciplinary performance scores were recorded. Several observations were collected for each official during the season. Statistical analyses: a structural equation model was run. In this model self-efficacy items were considered as indicators of a self-efficacy latent variable which have been considered as independent in the model. For each aspect of the performance (athletic, technical, behavioural and disciplinary) rated by the outside observers, it was calculated a mean of the observations collected during the year. These means served as indicators of the latent variable "performance" which has been considered as a dependent variable in the model. Results: Results indicated that the model fit adequately the data (CFI = 0,94; NNFI = 0,93; RMSEA = 0,05; CI = 0,03-0,06).
