Parent-Child Interaction Therapy (PCIT) is an evidence-based therapy for oppositional and defiant children ages 2 to 7. PCIT places an emphasis on improving the quality of the parent-child relationship, while teaching the parent to implement effective discipline techniques in the home.

The treatment consists of two parts:

Child-Directed Interactions (CDI) - parents are taught specific behavioral play skills in order to nurture the parent-child relationship.

Parent-Directed Interaction (PDI) - parents are instructed on how to give effective directives to their children and follow these directives with clear, consistent consequences for behavior.

During PDI, parents are provided the opportunity to practice discipline techniques with the coaching and supervision of a therapist. Parents learn skills through direct coaching sessions, and then implement these skills under therapist supervision with the use of a one-way mirror and "bug-in-the-ear" receivers.

Research studies of the effectiveness of PCIT consistently find clinically significant improvement in child compliance to parental directives and decreases in disruptive behaviors.
