Research suggests that the arts can have a positive impact on youth development, from birth through adolescence. This review explores recent research on arts-based programs and arts therapies. Programs were considered arts-based if at least one of the main components was an arts-related activity, or if there was a deliberate use of arts in the program to bring about a change in behavior. This category includes standalone, arts-based interventions as well as programs incorporating the arts in combination with other approaches (such as mentoring). The review focuses on the following three populations: (1) at-risk youths, (2) justice-involved youths, and (3) traumatized youths.
