This supplement to the 2018 Children’s Mental Health Report from the Child Mind Institute provides suggestions on how to talk about difficult subjects with teens. It discusses how to maintain ongoing conversations about normal fears, how persistent anxiety can develop into a disorder, and why early treatment is best. This guide describes how adults can build rapport with teens by being curious without being judgmental, showing trust, being collaborative, giving praise, and staying calm. It covers general anxiety; social anxiety; social media risks and rewards; anxiety and substance abuse; anxiety disorder, depression, and suicidality; and treatment.
