Depression is a serious illness that affects a person's mood, thoughts, and physical well-being. Research suggests that approximately one in five children meets criteria for a major depressive episode by the end of high school. These children are at increased risk for a wide range of social, psychological, physical, and achievement-related problems. Thus, the potential benefits of effective and highly transportable depression prevention programs are enormous. The Penn Resiliency Program (PRP) is a school-based group intervention that teaches cognitive behavioral and social problem-solving skills to young adolescents. This study will examine the effectiveness of PRP in preventing symptoms of depression and anxiety among a group of young adolescents.
