BackgroundThe #MeToo and #Times Up movements have put a global spotlight on the phenomenon of sexual harassment in healthcare. Yet, most studies have explored sexual harassment among female professionals. This study departs from current research practices and investigates the frequency of sexual harassment in male nurses working in the Greek NHS and the reasons for not reporting their experiences.MethodsA cross-sectional study was conducted using the Sexual Experiences Questionnaire (SEQ) to collect data from 507 male nurses working in Greece's various settings during October and February 2021. The electronic survey was sent to male nurses (n=3,091 registered with the Hellenic Association of Nurses. Survey items were consent form, demographics, three-dimensions of sexual harassment, silencing and negative consequences. Questions were measured using five-point Likert scales, binary scale and multiple-choice questions. ANOVA and T-tests were used to investigate whether specific groups more frequently dealt with sexual harassment. Multiple regression analyses were conducted to investigate the association between independent variables (sexually harassing behaviours) and the dependent variable (participants' negative physical, mental, and job-related outcomes).Results40% of male nurses have experienced sexual harassment at least once in their working lives, and the most common form of sexual harassment faced was gender harassment, followed by unwanted sexual attention. Male doctors and male nurses were the most common perpetrators. Private and younger male nurses with up to 5 years of experience experienced more frequent sexual harassment. 30% did not report sexual harassment due to the fear that no one would believe them, and because of beliefs, no action would be taken against the wrongdoer. Multiple regression analyses showed that unwanted sexual attention and sexual coercion were associated with physical and job-related outcomes. Cronbach Alpha was 0.91.ConclusionA high proportion of male nurses have experienced sexual harassment during their careers. Being younger with limited working experience and working in the private sector were positively associated with sexual harassment. Policymakers and health managers should focus on sexual harassment prevention strategies and report-enabling policies.
