Following a high profile case of child sexual abuse in sport in 1996, the Netherlands Olympic Committee and the Netherlands Sports Confederation (NOC*NSF) established a telephone ‘helpline’ service on sexual harassment and abuse (SHA). In order to expand their understanding of this problem, the NOC*NSF maintained written records of incidents reported to the Helpline. These records revealed 323 separate incidents for the period 2001 to 2010. This paper presents a descriptive analysis of this data and discusses the findings. We conclude that whilst there are major limitations to working with information gathered in this way, a sustainable telephone ‘helpline’ can provide a valuable service for the sports community. Whilst official sources of data are known to under-represent the scale of sexual abuse, through collaboration with researchers, such services can also generate important information for policy-makers.
