Screening-to-Intervention Pathway for Child Anxiety Problems Alongside Usual School Practice Versus Usual School Practice Only (iCATSi2i): A Cluster-Randomised, Controlled Trial in Primary Schools in England

Reardon T, Williamson V, et al. · The Lancet Psychiatry · April 2026

This cluster-randomised trial screened children across 84 primary schools in England for anxiety problems, then randomised 409 children who screened positive to either a parent-led, therapist-supported online CBT pathway (seven modules plus brief practitioner calls) or usual school practice alone.

At 12 months, 61% of children in the intervention pathway no longer screened positive for anxiety, compared with 38% in the usual-practice group — a gap large enough to matter well beyond statistical significance. Teachers also reported a sustained reduction in classroom anxiety impact out to 24 months, suggesting the effect wasn't just a parent-reporting artifact.

💡 Why it matters

A low-intensity, parent-delivered pathway triggered by school screening resolved anxiety in most children who'd otherwise have been left to "grow out of it" — a model worth knowing given how few child psychiatrists exist to see them individually.

📚Landmark Study

Cognitive-Behavioral Therapy, Imipramine, or Their Combination for Panic Disorder: A Randomized Controlled Trial

Barlow DH, Gorman JM, Shear MK, Woods SW · JAMA · May 2000

This four-site, double-blind, placebo-controlled trial randomised 312 adults with panic disorder to imipramine alone, panic-control cognitive-behavioral therapy (CBT) alone, placebo, CBT plus imipramine, or CBT plus placebo, tracked through acute treatment and a 6-month maintenance phase.

Both active monotherapies beat placebo acutely (response rates of 45.8% on imipramine and 48.7% on CBT versus 21.7% on placebo), and neither was significantly better than the other. Combination therapy showed a modest edge by the end of maintenance but wasn't clearly superior to CBT plus placebo — and CBT's benefits proved the most durable after treatment stopped.

This is chapter 1 of *50 Studies Every Psychiatrist Should Know* (Bhalla, Tampi, Srihari — Oxford, 2018), part of a rotation bringing one landmark trial into this briefing roughly every seven issues.

💡 Why it matters

Twenty-five years on, this trial is still why reflexively stacking medication onto CBT for panic disorder shouldn't be assumed to add durable benefit — the acute response is comparable either way, and CBT alone tends to hold up best once treatment ends.

💊Psychiatric Fact

Stopping clozapine abruptly doesn't just risk relapse — it risks a cholinergic rebound that looks like one

Clozapine is one of the most potently anticholinergic antipsychotics in use, and chronic muscarinic blockade drives compensatory upregulation of muscarinic receptors. Stop the drug abruptly — a missed refill, a hospitalization, a patient who simply quits — and that upregulated system is suddenly unopposed. The result is cholinergic rebound: diaphoresis, hypersalivation, GI hypermotility with diarrhea or cramping, insomnia, and agitation, typically within 24 to 72 hours.

The trap is that rebound can also produce a florid rebound psychosis distinct from ordinary relapse — more abrupt in onset, often with prominent agitation and autonomic symptoms out of proportion to the psychotic content — and it is easy to misread as "the underlying illness returning" and respond by loading a different antipsychotic rather than recognizing a withdrawal state. The practical implication: whenever possible, cross-titrate over 1 to 2 weeks rather than stopping cold, and when abrupt discontinuation is unavoidable (nonadherence, agranulocytosis), watch specifically for the autonomic cluster alongside any psychiatric symptoms before concluding the psychosis is purely disease-driven.

🛋️Psychotherapy Teaching Pearl

Defusion doesn't argue with the thought — it changes what the thought is made of

Acceptance and Commitment Therapy's cognitive defusion is easy to mistake for a softer version of CBT's cognitive restructuring, but the target is different: restructuring evaluates whether a thought is *true*; defusion changes a patient's *relationship* to the thought regardless of its truth value. The working assumption is that language itself is the trap — once a thought like "I'm a burden to everyone" is fused with identity, every attempt to argue it down ("but that's not true, look at the evidence") only strengthens its grip, because arguing accepts the thought's premise that its truth is what matters.

Defusion techniques instead make the thought's *form* strange — saying it slowly, singing it, prefacing it with "I'm having the thought that..." — which doesn't change the content but changes the thought from something the patient is standing inside of to something the patient can notice. The technical move is content-neutral: it works the same way whether the fused thought is true, false, or unresolvable, which is precisely the point for thoughts no amount of evidence will settle.

🗒️ Vignette

A patient with chronic pain says, flatly, "I'm broken, and no one wants someone broken." The therapist doesn't reach for evidence against it. Instead: "Say it again, but this time start with 'I'm having the thought that...'" The patient does, visibly resisting — it feels like a trick, like it's letting the thought off easy. The therapist asks her to say the bare phrase "broken and unwanted" ten times, fast, until the words dissolve into sound. Something shifts in her posture. "It's just words," she says, surprised, not because she now believes she isn't broken, but because the thought has stopped operating as a verdict she has to either accept or defeat — it's become one more thing showing up in her mind, which she can carry into the next hour of her day.
