Parent-Child Interaction Therapy (PCIT)

Parent-child interaction therapy (PCI, often called PCIT) is a family of approaches where a therapist coaches you, the parent, rather than working with your child alone. You learn ways of interacting that build your child's communication, relationship, and behaviour — then practise at home between sessions.

What it is

• Developed in the 1970s by Dr. Sheila Eyberg, drawing on attachment theory (how secure relationships form) and social learning theory (children learn by watching and imitating).
• First used for behaviour problems, it has since been adapted for speech and language issues: delayed speech, autism, delayed social skills, and hearing loss.
• It has two phases:
  • Child-directed interaction — your child leads the play; you follow and comment. This builds the relationship.
  • Parent-directed interaction — you lead, with a focus on behaviour.
• A typical format is weekly sessions plus short homework (for example, five-minute daily exercises). Coaching can be live (you wear an earpiece while the therapist watches from another room), video-recorded and reviewed together, or online.

The VERVE variant

UK speech and language therapist Keena Cummins adapted PCI into VERVE, an "adult stays quiet, child watches faces" technique built on short recorded interactions. The name spells five elements:

1. Video — you and your child are recorded in short clips.
2. Endorse — you work on ONE skill at a time (naming, repeating, pausing, waiting for eye contact), adding another only when it's mastered.
3. Respect — you watch your own videos, share your thoughts, and are treated as a partner in planning.
4. Vitalise — the shared experience builds your sense of progress and your child's confidence to explore.
5. Eye contact — you wait for your child to look before speaking, so your words pair with lip-reading and facial expression.

Why it matters for communication

The habits it teaches are the same ones speech therapists repeat in home programs:

• Comment, don't interrogate. Questions can raise anxiety for a child with delayed speech. Commenting on play ("You're building a tower") invites engagement instead of demanding a reply.
• Expand. Add words and grammar to what your child says or does, without pressuring them to repeat.
• Let the child lead. Follow your child's play choices and reinforce positive behaviour, so negative behaviours gradually fade.

How strong is the evidence?

• The studies cited are small (around 18 children each) but show positive results for language, behaviour, and social skills in children with delayed speech or hearing loss. Research on PCI specifically for speech is "still in the early stages."
• Flag: the source book claims PCI cuts behavioural problems and meltdowns "by approximately 85%" in young children, but gives no retrievable citation — treat it as an impression, not an established figure.
• The broader idea of parent coaching is well established in early intervention (the Hanen Centre is a known example); evidence for PCI for speech specifically is thinner.

Who it may help

• Delayed speech — you learn to comment, expand, and add vocabulary in everyday moments.
• Autism — parents reported finding their child's difficulties less challenging after practising PCI, possibly because frustration-driven behaviour eases.
• Delayed social skills — you become a better model for your child to learn from.
• Hearing loss — parents become more responsive and emotionally available.

Not medical advice. PCI is a professional therapy — it should be delivered or supervised by a trained therapist (a speech-language pathologist or mental-health professional). What you can safely practise at home is the habit of commenting, following your child's lead, and expanding their language.
