Non suicidal self-injury (NSSI), intentional self-inflicted injury to one’s body with no suicidal intent, is one of the strongest predictors of future suicidal ideation and attempts. People with NSSI are found to have greater emotion dysregulation, greater rumination, and poorer executive functioning, all of which can lead to difficulties with consistent skills engagement. Mindfulness – a core skill in evidence-based treatments for NSSI – has been found to target many of these deficits and may be particularly relevant due to a proliferation of digital mindfulness interventions (DMI) in recent years. Although DMI have potential, cognitive-affective deficits underlying NSSI may exacerbate difficulties with effective and consistent use of DMI to receive its benefits.
In this presentation, Dr. Cheung will share findings from the pilot study, RUME, that aimed to develop a program of ecological momentary assessment (EMA)-based habit-formation strategies to boost user engagement and treatment effects of a DMI app. The presentation will highlight quantitative and qualitative feedback from participants that were used to inform design considerations, as well as explorations on the use of EMA as both an intervention and outcome measure in self-harm research.
