PCIT (Parent-Child Interaction Therapy)

By the time most families come in for PCIT, the parents have already read the books, asked the in-laws, tried the timeout chart, and watched another bedtime end in tears (their child’s, sometimes their own). What helps a four-year-old cooperate is not more parenting advice. It is being shown, in the moment, what to do, and having the chance to practise it while a clinician quietly coaches you through.

That, in one sentence, is what PCIT is.

What PCIT actually is

Parent-Child Interaction Therapy (PCIT) is an evidence-based behavioural intervention for children aged 2 to 7 with disruptive behaviour, defiance, aggression, or strained parent-child dynamics. It is one of the most rigorously studied treatments in child psychology, with over forty years of randomised trials and meta-analyses behind it.

What makes PCIT unusual is the format. The parent is the one delivering the intervention. I sit behind a one-way mirror (or, in our setting, in a quiet observation arrangement) and coach you live through a small earpiece while you play with and parent your child in the next room. You hear specific guidance in the moment: “Praise the way she just shared,” “Stay with the play, give him a minute,” “Now is the time to give the instruction.” The skills go in through your hands, in your own voice, with your own child. Not through homework, not through hoping you’ll remember it next week.

The two phases

Phase 1 — Child-Directed Interaction (CDI)

The first phase rebuilds the warmth between you and your child. Most families who arrive in PCIT have spent the last year mostly correcting, redirecting, or managing their child. CDI deliberately suspends that. For five minutes a day at home, and for the first stretch of every session, you follow the child’s lead in play. You learn the specific skills that strengthen attachment and self-regulation in young children: descriptive praise, behaviour description, reflection, imitation, enjoyment.

It sounds simple. The change it produces in a child’s behaviour, often within the first three to four sessions, is not subtle.

Phase 2 — Parent-Directed Interaction (PDI)

Once the relationship is steady, the work moves to limit-setting. PDI teaches you to give clear, calm, age-appropriate instructions and to follow through with consistent, non-punitive consequences when the child does not comply. The earpiece coaching makes the difference here too. The first time you give a PDI instruction with your child halfway up a sofa with a marker in his hand, you don’t have to remember the protocol. I’ll walk you through it, sentence by sentence.

By the end of Phase 2, the patterns that brought you in (tantrums that lasted forty-five minutes, mornings that felt like negotiating with a small lawyer, evenings that ended in shouting) have usually shifted enough that families can tell the change without a measure. I use a measure anyway. Standardised behaviour tracking at every session means the progress is documented, not guessed at.

Mastery, not session count

PCIT is mastery-based. You graduate when you can deliver the skills at criterion levels in observation, not when a particular number of sessions has elapsed. That said, most families finish in 14 to 20 weekly sessions. Some are quicker; some, with significant comorbidity or a child whose temperament needs more time, take longer. The work ends when the work is done.

Who PCIT is the right fit for

• Children aged 2 to 7 with frequent tantrums, defiance, aggression, hitting, biting, or extreme non-compliance.
• Parent-child relationships that have become heavy, conflictual, or coercive, where most of the day’s interactions have become corrective.
• Children with disruptive behaviour related to ADHD, anxiety, adjustment, or early developmental concerns.
• Foster, adoptive, and blended-family households navigating attachment and behavioural challenges together.
• Parents who have already tried “parenting strategies” and are not looking for more advice. They are looking for in-the-moment coaching.

My training

I am PCIT-certified, trained at UT Health San Antonio’s PCIT and ADVANCE Clinics during my predoctoral internship. PCIT certification is not casual: it requires supervised cases to mastery and direct observation by a certified trainer. My broader background in child psychology (Mayo Clinic, UNC Chapel Hill, UT Health San Antonio) means I can also assess and manage the co-occurring conditions (ADHD, anxiety, autism, learning differences) that often travel alongside disruptive behaviour in young children.

When PCIT sits inside a bigger picture

PCIT often arrives via a wider clinical question. Many children referred for “behaviour” are also showing signs of ADHD, autism, anxiety, or sensory sensitivities. Part of the first consultation is sorting out what’s driving what, so the work doesn’t end up treating the wrong thing.

For the wider behavioural and school-related picture, see behavioural difficulties & school refusal. For formal assessment in older children, see ADHD & neurodiversity for children (6–12). For younger children, the diagnostic clarification fits inside the first PCIT consultation rather than a separate testing battery.

Who this isn’t right for

PCIT is not the right starting point if your child is older than 7. Different protocols apply, and behavioural family work or individual CBT may be a better fit; see the behavioural difficulties & school refusal page. It is not the right starting point if the primary concern is severe trauma needing specialist trauma-focused work, or if active safety concerns require a higher level of care than my outpatient practice can provide. /clinical-fit/ walks through how I think about fit, and I will say so on the first call if a different service is the better starting point.

Sessions, fees, and scheduling

PCIT sessions are sixty to ninety minutes, pro-rated at SGD 300 per hour. The first consultation (intake, behavioural observation, treatment planning) is usually up to two hours at SGD 600. A typical course of PCIT is 14 to 20 weekly sessions. After-hours sessions (weekday evenings, Saturdays, Sundays and public holidays) carry a published rate. Full structure on the fees page. Payment is due before each session.

If you are not yet sure whether PCIT is the right fit, the free 15-minute Meet & Greet (Zoom or phone) is the easiest place to begin.
