Can an app break the cycle of self-harm? New study investigates digital support for youth with non-suicidal self-injury

Non-suicidal self-injury (NSSI) is a growing concern in healthcare, often marked by silence and shame. A new clinical trial investigates whether the app Zero Self-Harm can reduce the number of self-harm episodes, suicidal thoughts, and depressive symptoms. The app, which is anonymous and developed in collaboration with users, may provide accessible support for those not engaged with the psychiatric system.

The study is a 6-month randomized controlled clinical trial with two groups and multiple participating centers. A total of 280 participants with NSSI were randomly assigned to one of two intervention groups: one group received immediate access to the app, while the other—a waitlist control group—received access after six months. Participants completed questionnaires at enrollment, after 3 months, and after 6 months. The primary outcome was the number of self-harm episodes in the month prior to the 6-month follow-up, measured using the Deliberate Self-Harm Inventory.

Zero Self-Harm was developed in close collaboration with individuals who have lived experience with NSSI. The app does not necessarily focus on stopping self-harm completely, but aims to reduce harm and provide support in the moment—a principle that may make the app more useful and acceptable to its target audience.

If the app proves effective, it could become a valuable and easily accessible tool for individuals struggling with NSSI. Its discreet, user-driven format makes it particularly relevant in a context marked by stigma and barriers to traditional help.
