Facing the important methodological limitations of the instruments used for assessing the prevalence of interpersonal violence faced by young athletes, the aim of the present study was to propose and describe the use of a research instrument adapted to young and French-speaking athletes. In addition, by collecting preliminary data with a Swiss sample, we aimed to measure the different forms of interpersonal violence young athletes have experienced at least once during their sport practice. Our questionnaire was based on three existing questionnaires and adapted for a young audience. Regarding prevalence, results showed that among the 210 respondents, 75% declared psychological violence, 53% physical violence, 28% sexual violence and 21% reported no violence. The other results showed that this instrument appears to be well-structured to measure interpersonal violence and understandable for young athletes. Based on the strengths and limits of our instrument, the methodological need of standardization of research instruments is discussed in line with a need of more studies to fully understand the phenomenon.
