A prescribed CBT app alongside medication sped recovery in acute panic disorder

Design

Multicentre randomised trial, single-blind, 8 weeks

Population

66 adults with acute-phase panic disorder on medication (61 analysed), 6 Korean centres

Primary outcome

Percentage change in Panic Disorder Severity Scale self-report at week 8

Effect

−40.3% vs −17.6% (P = .007); responders 53% vs 17%

Six Korean centres randomised 66 patients with acute-phase panic disorder and frequent attacks to medication plus a prescription-based app, or medication alone, for eight weeks. The app combined structured cognitive behavioural therapy modules, a just-in-time module for use during an attack, and daily self-monitoring. Assessors were blinded; patients were not.

Of 61 analysed, the app group's panic severity score fell by about 40% against about 18% with medication alone, and the gap was already visible at two weeks. Just over half of app users reached a 40% reduction, against about one in six controls. Anxiety and catastrophic thinking improved more with the app; depression and fear of bodily sensations did not differ in a lasting way. Adherence averaged 78%.

The practical point is that self-guided CBT can start on the day medication does, rather than after a wait for a therapist. That matters most where CBT access is thin, which includes much of India. But this was one small trial of one app, with self-reported outcomes in unblinded patients, and five randomised patients were excluded from analysis.

• Consider pairing a structured, self-guided CBT programme with medication from the first visit for panic disorder, rather than waiting for therapy.
• Look for programmes that include a tool for use during an attack — that was part of what was tested here.
• Review app use at follow-up as you would adherence to a tablet; most participants here used it regularly.
• Expect early change: differences appeared within two weeks.
• Do not use an app in place of assessment for physical causes of panic-like symptoms.

Why it matters

Medication alone leaves many patients with frequent attacks for weeks; this suggests the gap can be shortened without a therapist's time.

Don't overread it

With 61 patients, self-reported outcomes and no blinding of participants, this is an early signal for one app rather than proof for digital CBT in general.

The statistics, in plain English

A responder was someone whose panic score fell by at least 40%. Seventeen of 32 app users met that against 5 of 29 controls — roughly one extra responder for every three patients given the app. In a trial this small, a few patients either way would move that estimate noticeably.
