Parent management training (PMT) involves educating and coaching parents to change problematic child behaviors using behavior modification techniques. PMT teaches parents positive reinforcement methods to improve behaviors like aggression and tantrums in preschool and school-aged children. PMT has been shown to reduce disruptive child behaviors and improve parental mental health. It was initially developed in the 1960s based on principles of operant conditioning to change parenting behaviors through positive reinforcement of appropriate child behaviors and limiting attention for inappropriate behaviors. Treatment typically involves parents learning these techniques over several weekly sessions focused on monitoring, reinforcing positive behaviors and using time-outs or removal of privileges for negative behaviors.
