Is this trial a fit for you?

Likely a good fit

Adults (18+) meeting DSM-5 criteria for chronic insomnia who can attend four 30-minute hypnotherapy sessions, are patients of a participating GP, and are covered by the French social security system.

Probably not a fit

Patients whose insomnia is attributable to substances, another medical or primary psychiatric disorder, those unwilling to try hypnosis, or those unable to attend local hypnotherapy sessions are less likely to benefit from this intervention.

What this trial studies

HypERR is a multicenter, randomized, open-label trial run through participating general practitioners who randomize patients to either E2R hypnotherapy or standard care without hypnosis. Patients assigned to E2R are referred to a local hypnotherapist and receive four 30-minute sessions delivered over six weeks, while control patients receive usual GP-led care which may include psychotherapy or medication but not hypnosis. Outcomes are collected by the GP at baseline, 3 months, and 6 months after randomization to track changes in insomnia symptoms and related functioning. The trial is embedded in routine primary care across multiple GP practices in France to reflect real-world delivery.

Why it matters

Potential benefit: If successful, E2R hypnotherapy could reduce insomnia symptoms and lower reliance on sleep medications for patients seen in primary care.

How similar studies have gone: While hypnotherapy and CBT approaches have shown benefit for insomnia generally, no randomized clinical trials have specifically tested the E2R hypnotherapy method for chronic insomnia to date.
