Parent-Child Interaction Therapy (PCIT) is an evidence-based treatment aimed at improving behavior and relationships between young children and their caregivers, typically between ages two and eight. The therapy involves three phases: Child Directed Interaction (CDI), Parent Directed Interaction (PDI), and Parent-Child Counseling, focusing on live-coaching techniques where therapists guide parents to reinforce positive behaviors and effectively manage negative behaviors. Research indicates that PCIT can lead to significant improvements in child behavior and parenting skills, making it suitable for various family dynamics.
