The PBSI Association of Jambi Province has referees from various districts across Jambi who are actively involved in officiating matches at both provincial and national levels. Through this system, badminton referees in Jambi are organized into one forum to develop their skills, achieving accomplishments through a long process. During this formation process, several influencing factors have been identified. The referees’ mental condition while officiating—whether at the amateur or professional level—often experiences issues such as nervousness, anxiety, and even loss of concentration when making decisions. Various phenomena may occur during badminton matches in Indonesia, at both amateur and professional levels, in which referees often become central figures in controversial decisions. The purpose of this study was to determine the level of anxiety experienced by badminton referees before and during officiating matches in Jambi Province.
