Research illustrates that nearly one half of all children experience a form of sibling abuse during childhood. Sibling abuse is often hidden or excused as sibling rivalry, yet can have lasting long-term psychological effects. In this presentation key findings from a recent phenomenological study with school counselors will be shared. These findings can help counselor educators advance their understanding of sibling abuse and develop advocacy and prevention strategies to utilize in the instruction of counselors-in-training and their work with children and families.
