In Adolescent Pregnancy Prevention programs, the language and terminology you use can either make youth feel valued and supported or it can stigmatize and marginalize them, affecting their self-esteem and motivation to participate in programming. Language choices are especially important when it comes to discussing sensitive topics such as sexual behavior, pregnancy, and sexually transmitted infections (STIs). This tip sheet provides practical guidance on using affirming, non-stigmatizing language when working with adolescents in APP programs and other Positive Youth Development (PYD) programs.
