This study developed the Organizational Citizenship Behavior (OCB) Scale for sport. In preliminary Survey 1, aspects of OCB required of sport team members were examined based on coaches' practical experiences gained through free descriptions. A total of 71 descriptions were obtained, which were classified into six types. In preliminary Survey 2, items for assessing OCB required of sport team members were developed and 41 items were extracted. Participants were male university soccer club members (N＝301, Mean age, 19.82 years ± 1.12 years) belonging to five universities that had participated in the national soccer tournament in the past. In the main survey, exploratory factor analysis was conducted with responses to 41 items that were developed through the preliminary survey by male university soccer club members (N＝545, Mean age, 20.12 years ±1.08 years) that had participated in the national soccer tournament in the past. The results indicated five factors, consisting of 20 items: “Sacrificial behavior,” “Effective communication,” “Interpersonal support,” “Integrity,” and “Cleanness.” Reliability and validity of the 5 factors and 20 items were examined. The results indicated the reliability and stability of each factor, as well as the complete scale. The scale, developed through this study, was named as the “OCB scale for sport,” which is designed measuring individual OCB in sport teams.
