There's been another warning about referee abuse at junior sports games, with WA rugby associations banding together to warn of the damage it's doing to the sport.

A letter signed by the heads of Rugby WA, Rugby WA Juniors and the WA Rugby Union Referees Association has outlined the ongoing trend of match officials being abused across all ages.

One example listed was a young female referee quitting her position after a coach undermined her at a youths match.

Psychologist Dr Marny Lishman joined Chris to discuss why this problematic behaviour has become so common place in our kids sports.
