Child parent relationship training (CPRT)
"The goal of CPRT is to strengthen the quality of the parent-child attachment bond as a means of reducing child behaviour problems and stress in the parent-child relationship. CPRT was developed for children ages 3- 8, but has been adapted for use with toddlers and preadolescents. In CPRT, parents are taught specific skills grounded in the principles and procedures of Child Centered Play Therapy (CCPT) that focus on establishing or enhancing a secure attachment with their child and helping parents attune to and respond to their child's underlying needs rather than focus on symptoms. Parents also learn to effectively limit their child's misbehaviour, while demonstrating empathy and respect for their child."
