Child abuse increases the day after school report cards are released - but only when kids get their grades on a Friday.
That's according to a study in Florida published online Monday in JAMA Pediatrics.
The curious finding startled researchers. They'd figured abuse might go up regardless of the specific day kids got their grades. They speculated that punishment may become more abusive when kids don't have school the next day and parents think injuries might go unnoticed.
Other experts said the study shows that abuse and corporal punishment are still too common.
