Inequalities between men and women in the workplace are reflected in professional sports,
specifically football refereeing. This phenomenon sometimes becomes sexual harassment since it
is a stereotypically considered male profession in which women are a minority. To measure that
behavior, it is necessary to count on valid and reliable tools. Therefore, the goal of this study was
to determine the factorial structure and the discriminant and convergent validity of the ‘sexual
experiences questionnaire’, version of the Department of Defence (SEQ-DoD). Eighty-nine male
football referees and ninety-four female football referees, with a mean age of 23.30 ± 4.85 years,
participated in this studio conducted questionnaire in Andalusia, Spain. A confirmatory factor
analysis was performed using the robust maximum-likelihood estimation method. The goodness of
fit was assessed, and the factorial invariance was calculated to determine the stability of the model.
Subsequently, the validity was confirmed. The results corroborated the validity and reliability of the
questionnaire adapted to the population studied. Therefore, it can be used as a research instrument.
