You Matter is a safety card tool to support teens who have histories of adverse childhood experiences. It was developed in collaboration with young people, adolescent health providers and school based health center staff. Designed for young people who receive health services or classroom presentations, this card can help adolescents recognize how relationships and histories of trauma may impact their health and wellbeing. The tool identifies specific health problems associated with chronic stress and with neglectful and/or abusive relationships. It also provides guidance on healing, resiliency, and harm reduction, as well as identifies where teens can find support, including national hotlines. The safety card tool offers guidance for both health care providers, and for adolescents and their peers, who may also need support. The card is in English, features 5 double sided panels, and folds up to the size of a business card (3.5″ x 2″).
