Analysis of Basketball Referee Decision-Making Using the DMQ-II Questionnaire.

Basketball is a sport whose regulations require quick and complex refereeing decisions. Since the inception of sports, research on sports judgment and refereeing has been consistently present in the scientific literature. However, decision-making and the psycho-emotional factors that influence it remain somewhat unexplored in studies. The decision-making of the basketball referee has been analyzed using the DMQ II questionnaire. To achieve this, 58 referees from the Spanish Basketball Federation collaborated, comprising 45 men and 13 women, all between the ages of 18 and 38 (M = 26.5, SD = 5.5). Participants completed the 31-question DMQ II questionnaire online, yielding results with significant differences based on age and gender about stress in decision-making. A modification of the referee's teaching methodology that includes psychological strategies is proposed both in the initiation course and throughout the refereeing career. The findings highlight the need for mental health support systems for referees, particularly addressing stress management in young and female officials. This aligns with global efforts to safeguard psychological well-being in sports professionals.
