Part II - Why do children and young people drop out of sport? A Dynamic Tricky Mix of Three Rocks, Some Pebbles and Lots of Sand.

Organised sport is one potential antidote to the global youth inactivity crisis. Therefore, under-standing why young people drop out constitutes a key research endeavour. In paper 1 of this se-ries, we developed and validated a new Youth Sport Dropout Questionnaire (YSDQ). In paper 2, we used the YSDQ-LV (49-item long version) to examine dropout in 1127 university students from seven European countries. A four-stage analysis investigated the relative and combined im-portance of dropout reasons. Three items – the rocks – were statistically more important: “I prior-itised schoolwork and had no time left to take part in sport”; and “I found other things that I en-joyed doing more than sport”; and “I found it stressful when I did not perform/play as well as I expected”. On average, however, these rocks were rated as “moderately important”, along with 18 reasons (the pebbles) rated as “slightly important to moderately important”, and the remain-ing 26 reasons (the sand) rated as “slightly important to not at all important”. These findings suggest that sport dropout is not caused by a single reason but is underpinned by a dynamic tricky mix of reasons – a series of rocks, pebbles and sand unique to each young person.
