Brief Summary
The present study will use a randomized controlled design to investigate group differences between students with and without a history of nonsuicidal self-injury (NSSI) in response to a single-session mindfulness induction across conditions (formal mindfulness induction, informal mindfulness induction, active control task) in terms of the intervention's acceptability and effectiveness. Effectiveness will be inferred via pre-post changes in state mindfulness, state stress, and state well-being.

Outcome Measures
Primary Outcomes (1)
Change in state mindfulness (as measured by the VAS)
A Visual Analogue Scale (VAS), an instrument commonly used in induction research (e.g., Hessler-Kaufmann et al., 2020), will also be used to assess the momentary experience of five mindfulness facets, as generally described by Baer et al. (2006). Specifically, there will be five researcher-developed VAS items (one for each facet of mindfulness), modelled on the items in the Five Facets of Mindfulness Questionnaire (FFMQ; Baer et al., 2006). Each VAS will consist of a small, unmarked ruler with anchors labeled as "0 = Not true at all" and "10 = Completely true." Instructions will read: "Please indicate the extent to which each statement below accurately reflects your experience in this moment on the corresponding ruler below by dragging the slider," for each of the five facets of mindfulness. Each scale will yield a single subjective state mindfulness facet score from 0 to 10, where a higher VAS score indicates greater state mindfulness (on that facet).

Study Arms (3)
Formal mindfulness induction
EXPERIMENTALInformal mindfulness induction
EXPERIMENTALActive control task
ACTIVE COMPARATORInterventions
The formal mindfulness induction will consist of a 10-minute audio recording of a sitting meditation, guiding the participant to consciously and repeatedly bring their attention to their breath and inner experience with nonjudgmental acceptance.
The informal mindfulness induction will consist of on-screen instructions guiding participants through the completion of four routine tasks (washing hands, drinking water, laying down, listening to music) with mindful awareness and acceptance over the course of 10 minutes.
Participants assigned to the active control condition will be prompted to download a single-page document containing 100 letters, numbers, and symbols, and a grid of 100 boxes. Following along with a guided audio, participants will be instructed to place all of the characters in the grid in a specific order over the course of 10 minutes. A version of this task has been used in previous studies by our team (Carsley \& Heath, 2019; Petrovic et al., 2022) and has been shown not to impact mindfulness levels, and was thus deemed an appropriate neutral attention task for this study.
