- Abstract
The purpose of this preliminary investigation was to use a Naturalistic Decision Making (NDM) paradigm to assess the decision-making accuracy, agreement and coherence of 132 of England's best Rugby Football Union (RFU) officials. Following presentation of video recordings of actual game scenarios, 45 referees, 47 touch-judges, 27 assessors and 13 referee coaches made immediate decisions on 10 videotaped tackle incidents. The referees consisted of three subgroups based on their national ranking and the level at which they referee, top-20, 21-40 and 41-65. The mean accuracy of all groups was low (M = 49.6%, SD = 28. 6%), and since experts deemed these types of tackles to occur about 11 times per game, this suggests that nearly six tackles per game would be adjudicated incorrectly. In addition, the officials' confidence in the accuracy of their decisions rarely decreased even when their decisions became more discordant. Reflecting ecological validity of the test, the top-20 referee group displayed the highest accuracy levels (M = 54.3%, SD = 32.9%), and the referee coaches revealed the lowest levels (M = 43.0%, SD = 37.3%). In addition, officials were most accurate when they had shared mental models, in this case represented by shared reasoning for their decisions. Consequently, this study offers a new perspective for the evaluation of sports officials and also lends further credence to the use of video simulations to assess DM through a naturalistic paradigm.
