Validation of the Mental Toughness Measure of Athletes and Non-athletes with the Structural Equation Model

The use of structural equation models (SEM) in scientific research perform a promising methodological and empirical direction to validate the measurement psychological constructs. aim this paper is mental toughness athletes non-athletes with SEM. sample consisted 853 Tunisian participants (444 males 409 females; 444 non-athletes), aged 14 27 years (M=20.38 SD=4.12). completed Arabic translated questionnaire Clough, Earle [1] which measures six components their toughness. SEM approved good model fit (χ ² =1146.33; df =1065; CFI=.93; SRMR=.063; RMSEA=.009) allows for valid Arabic-speaking measure
