Risk experiences can increase acting out behaviors and depressed mood in children. However, not every child experiencing these things develops acting out behaviors or depressed mood.  One possible explanation is that these risks interact with the child's genes. This is only a possibility, however, and has yet to be fully tested.  TBED-C thus recently assessed twin children 6 to 10 years of age, and their primary caregivers.  The primary focus was to look at relationships among genes, mood, peers, family relationships and acting out behaviors in children. Analyses of existing data (125 twin pairs) are currently underway. We are currently collecting more data from families in Flint and Detroit. This study is directed by Dr. Alexandra Burt.
