In this video sponsored by the National Institute of Mental Health, Drs. William Copeland and Christopher Sarampote discuss the mental health consequences of childhood bullying . In the July issue of the American Journal of Psychiatry, Drs. Takizawa, Maughan, and Arsenault report bullying data from the British National Development Study. This is a 50-year prospective cohort of 17,638 individuals born in 1958. Parents reported childhood bullying in 7,771 or 44% of them. The authors found that childhood bullying victims have higher psychological distress, rates of depression, anxiety, and suicide, less social relationships, more economic hardship, and poorer perceived quality of life than individuals who were not bullied. In an editorial, Dr. E. Jane Costello suggests improving mental health outcomes of childhood bullying victims by doing more research on primary prevention (i.e., intervention before bullying) , secondary prevention (i.e., intervention during bullying), and tertiary prevention (i.e., intervention to prevent mental health consequences after bullying). Given the high rates of childhood bullying and its consequences, Dr. Costello emphasizes the importance of asking patients and parents about a history of bullying.
