Aim: To validate the Spanish version of Adonis Complex Questionnaire in bodybuilders. Method: Participants included 99 bodybuilders who train regularly (age: 25.45±5.19 y; BMI=24.53±1.89). In order to test the discriminant and concurrent validity the Exercise Dependence Scale-Revised (EDS-R) and the Eating Attitudes Test (EAT-26) were used. The scale's psychometric properties were obtained through a concurrent validity process, factorial analysis of principal components, internal consistency, and test-retest reliability. Results: The internal consistency of this questionnaire was high (Cronbach's Alpha= 0.880) in total scale. The intraclass correlation coefficient (ICC) to test the temporal consistency of the questionnaire was 0.707 (95% IC=0.336- 0.871). The questionnaire obtained concurrent validity with the EDS-R (r=0.613, p<0.001), and EAT-26 (r=0.422, p<0.001). The results have shown a three-factor structure Factor 1: psychosocial effect of physical appearance, Factor 2: control of physical appearance, Factor 3: concern about physical appearance which explain 65.29% of variance. Conclusion: The Adonis Complex Questionnaire shows a proper psychometric properties and it is a valid and reliable measure of vigorexy and muscle dimorphism in bodybuilders.
