Thirty-four elite Referee Match Observers (RMOs) from the Portuguese FA participated voluntarily in the study. From the official assessment sheet of each game, the referee\u2019s game score was categorized in two groups according to referee\u2019s game score: i) Referees with a Low Score (LFS) and ii) Referees with High Score (HFS). A multivariable binary logistic regression model was used to assess the relationship between the Performance Indicators (PIs) of the dimensions i) game difficulty and game intervention and ii) disciplinary actions and game management in relation to the referee\u2019s match assessment score. The model proposed revealed that only the PIs negative application of the laws of the game and referee teamwork, from the dimension disciplinary actions and game management, significantly defined the final game referee\u2019s assessment score. This study suggests that the PIs scored by the RMOs contributed in a different way to the referee\u2019s game score. The model explains 60.4% of the referee\u2019s game score based on the variables referee teamwork and negative application of the laws of the game.<\/jats:p>","DOI":"10.1371\/journal.pone.0291917","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T17:47:01Z","timestamp":1695318421000},"page":"e0291917","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["The
