Cochrane reviews on de-escalation training 2020: what they found

By awareretailgroup.com Editorial· Edited by Tom Walsh· Published 2026-09-25

Cochrane reviews find the evidence for de-escalation training is thin. A review of de-escalation techniques for non-psychosis-induced aggression concluded that its authors “cannot say whether de-escalation techniques are effective” (Cochrane). A review of education and training for healthcare workers found that such a program might not affect the number of aggressive incidents those workers experience (Cochrane). Both cover psychiatric and healthcare settings, not retail.

What it measured

Cochrane reviews pool controlled trials on a single question and grade the certainty of the combined evidence. The de-escalation review asked whether de-escalation techniques prevent violence from aggressive people whose aggression is not driven by psychosis. The education and training review asked whether programs for healthcare workers reduce aggressive behavior toward them. Neither review is about retail; the trials they pooled come from psychiatric and healthcare settings.

Headline findings

The de-escalation review could not reach a verdict. Its authors state that they “cannot say whether de-escalation techniques are effective” (Cochrane), and that high-quality research on the effectiveness of this intervention is therefore urgently needed (Cochrane). That is not a finding that de-escalation fails. It is a finding that the trials have not been run.

The training review found knowledge without incident reduction. Although an education and training program might increase healthcare workers’ knowledge and positive attitudes, such a program might not affect the number of incidents of aggressive behavior that healthcare workers experience (Cochrane). Over a longer horizon, education may not reduce aggression compared to no intervention in the long term (Cochrane).

How to use it in a program

The honest use of these reviews is to lower the claim, not to cancel the training. A retail program should not promise that de-escalation training will cut incidents. It can promise that associates will know the store’s rule, know where the exits and the alarm are, and know who to report to. Those are the outcomes the training review says training can move: knowledge and attitude.

• Rewrite the training’s stated goal from “reduce incidents” to “every associate knows the response rule and the reporting path.”
• Make the rule itself the content: observe, create distance, get help, report. Never confront, never chase.
• Measure what training can change: a short knowledge check after the session, and whether incidents get reported.
• Keep the store’s own incident log so that, over time, the store has its own evidence rather than borrowed evidence.
• Build the session using de-escalation training for retail associates, and put the store’s rule in writing in a customer aggression policy.

Limits

The reviews are about psychiatric and healthcare settings. A nurse facing an agitated patient and a cashier facing an angry shopper are different situations, with different stakes and a different ability to walk away. The findings do not transfer to retail beyond the plain statement that the evidence base is thin. The reviews also do not test the specific content of any retail training product, so a vendor’s claim of effectiveness is neither confirmed nor refuted by them. State laws such as New York’s require de-escalation content regardless of the evidence grade, so the training still has to happen; what changes is what a store says it will achieve.
