Participants will learn comprehensive cognitive, affective, behavioral, environmental, biological, and psychological interventions. Functional assessment and measurement of nonsuicidal self injury in youth will be discussed. Positive and negative replacement behaviors will be explored as will be mindfulness, emotional regulation, distress tolerance, and interpersonal effectiveness skill-building prescriptions.
