Recent research has shown that behavioral skills training with in situ training is an effective strategy to teach children the safety skills needed if they ever encounter an unattended firearm. The current study evaluated the use of parents as trainers to increase the efficiency of training. The success of parent training on their children's safety skills was evaluated in a multiple baseline across participants design. The results showed that the training was effective for 3 of the 4 children. (Contains 1 figure.)
