Reliability and validity of the Arabic version of coach-athlete relationship questionnaire: ACART-Q.

This study had a twofold purpose: (a) to create an Arabic version of the Coaches-Athletes Relationship Questionnaire (CART-Q) and (b) to assess its psychometric qualities in the context of Tunisia, as well as its sensitivity in other sports populations. The researchers conducted an online survey of 594 amateur athletes from different sports clubs in Tunisia. For the exploratory factor analysis, 157 athletes aged 22.72 ± 3.78 years were randomly selected, while confirmatory data were collected from 482 athletes aged 22.74 ± 7.63. The study found a three-factor structure through principal component and confirmatory factor analyses. CFA fit indices showed acceptable results for both second-order and first-order. The scale had excellent internal consistency for all three factors and total score, but only partially established sensitivity for the complementarity dimension. Gender and type of sport showed significant differences for the complementarity dimension. Cronbach's Alpha, McDonald's ω, and Guttmann's λ6 coefficients were all high at 0.88, 0.89, and 0.94, respectively. Overall, the results suggest ACART-Q is a valid instrument for assessing the coach/athlete relationship in the Tunisian context. The study provided valuable insights into its psychometric qualities and the questionnaire could be used by coaches, researchers, and athletes to improve their relationships and performance.
