Propiedades psicométricas del Exercise Addiction Inventory (EAI) en una muestra de estudiantes brasileños universitarios

The purpose of this study was to validate the Exercise Addiction Inventory (EAI) in the Brazilian context. A total of 251 university students (male = 132, female = 119, Mage = 22.34, SD = 4.65) participated in the study. Results showed an adequate fit to the data: χ² (9, N = 251) = 17.45, p = .04; χ²/gl = 1.94; CFI = .96; IFI = .96; RMSEA = .061 (IC 90 % = .01-.10); SRMR = .041. The factorial structure was invariant across gender. Adequate values of internal consistency (ρ = .70) and temporal stability (ICC = .82) were obtained. Sixteen students (6.4 %) were classified at risk of exercise addiction, 198 (78.9 %) as symptomatic and 37 (14.7 %) as asymptomatic. Evidence for the reliability and validity of the EAI in the Brazilian context were obtained. Nevertheless, research in more diverse populations is needed to further examine the general applicability of the EAI.
