Abstract
(1) Background: Sexual harassment in the workplace is a problem that particularly affects women and is not an exception in the world of work. Factors such as power asymmetry, the predominantly masculinized culture in many organizations, and the potential impunity of perpetrators increase the associated risks. This study aims to analyze the psychometric properties of the Sexual Experiences Questionnaire-Workplace (SEQ-W) to measure sexual harassment at work and assess its validity in Spanish. (2) Methods: A total of 120 active female workers (67.5% European and 32.5% South American) participated, completing validated instruments to measure sexual harassment, workplace bullying, self-perceived health, and job satisfaction. The questionnaires were administered online, ensuring anonymity and explaining the study's objectives. (3) Results: An exploratory factor analysis revealed a bifactorial structure with the dimensions "Sexual Harassment by Coercion" and "Harassment by Unwanted Sexual Attention." Both dimensions demonstrated adequate internal consistency, concurrent validity with workplace bullying and well-being scales, and discriminant validity with job satisfaction. Additionally, a pronounced floor effect was observed, indicating a low prevalence of sexual harassment in the sample. (4) Conclusions: the SEQ-W scale is a useful tool for assessing sexual harassment among active Spanish-speaking female workers, considering its validated bidimensional structure in Spanish.
