PCIT is an evidenced-based treatment model with highly specified, step-by-step, live coached sessions with both the parent/caregiver and the child. Parents learn skills through PCIT didactic sessions. Using a transmitter and receiver system, the parent/caregiver is coached in specific skills as he or she interacts in play with the child. Generally, the therapist provides the coaching from behind a one-way mirror. The emphasis is on changing negative parent/caregiver child patterns.
