Boston Public Schools Superintendent Tommy Chang sent a message to families this week warning them about the so-called “Blue Whale Challenge,’’ which reportedly uses social media to encourage self-harm and suicide among adolescents.

“We believe that part of our role is informing school communities when issues arise that can impact our youth,’’ Chang said in the letter on Wednesday. “There is debate as to whether this challenge exists. Despite this, we feel that it is important to share this information should you encounter this type of troubling trend with your child or anyone you know.’’

Boston Public Schools spokesman Dan O’Brien said the school system has received no reports of students expressing interest or participating in the game, and was acting out of caution.
