A new study has found teaching parents to switch channels from violent shows to educational TV can improve preschoolers' behavior, even without getting them to watch less.
The results were modest and faded over time, but the study authors and other doctors say they may hold promise for finding ways to help young children avoid aggressive, violent behavior.
The research involving 565 parents was published online Monday by the journal Pediatrics.
They periodically filled out TV-watching diaries and questionnaires measuring their child's behavior.
Half were coached for six months on getting their 3-to-5-year-old kids to watch shows like "Sesame Street" and "Dora the Explorer" rather than more violent programs like "Power Rangers."
Low-income boys appeared to get the most short-term benefit.
