Background Athletes’ perceptions of justice toward their coaches’ behaviours play a critical role in athlete satisfaction, team cohesion, and performance outcomes. However, no validated instrument exists to measure athletic justice perceptions among Turkish athletes.Aim This study aimed to adapt and validate the Turkish version of the Athletic Justice Scale developed by Kim et al. (2024).Methods The scale comprises 12 items across four subscales (distributive, procedural, informational, and interpersonal justice) measured on a 7-point Likert scale. Participants included 717 licensed adolescent athletes (402 males, 315 females; aged 8–19 years) from various sports in Türkiye. Following translation and back-translation procedures, content validity was established through expert panel evaluation (S-CVI/Ave = 1.00). Confirmatory factor analysis (CFA) was conducted, and measurement invariance was tested across gender, sport type, and coach gender.Results The four-factor model demonstrated acceptable fit indices (χ² = 167.47, df = 48, CFI = .981, TLI = .973, RMSEA = .059, SRMR = .040). All factor loadings were significant and ranged from .69 to .96. Internal consistency was acceptable to excellent across subscales (Cronbach's α = .739-.909; composite reliability = .742-.911). Full scalar measurement invariance was achieved across all demographic groups.Conclusion The Turkish version of the Athletic Justice Scale is a valid and reliable instrument for assessing adolescent athletes’ perceptions of justice toward their coaches’ behaviours. This tool enables researchers and practitioners to examine fairness perceptions within Turkish sport contexts.
