Abstract: Background: Sports performance is the result of an interaction of several variables, such as physical, technical, and psychological. The ability of athletes to use motivation, is an important predictor to achieve high performance in sport. SMS‐II comprised 18 elements to measure six behavioral control factors. Aim: This study aims to validate an Arabic version of the revised sports motivation scale‐II (SMS‐II) and measure the psychometric properties of factorial structure, internal reliability, construct validity, and sensitivity. Methods: A total of 780 athletes from different disciplines (432 men, 348 women; mean age = 18.97 years) participated in this study. Athletes voluntarily responded to the version of SMS‐II. Factorial validity was established by principal component analysis. Both exploratory (EFA; N = 390; males: 52.6%; females: 47.4%; [13–18] = 172; [19–30] = 218) and confirmatory (CFA; N = 390; males: 58.2%; females: 41.8%; [13–18] = 247; [19–30] = 143) analyses were examined. Results: The 18 SMS-II items revealed perfect reliability (McDonald’s omega = 0.841, Cronbach’s α = 0.858, Gutmann’s λ6 = 0.952) and good temporal stability (ICC = 0.960, 95% CI = 0.915–0.980; r = 0.935, 95% CI = 0.889–0.963 at p
