Nonsuicidal self-injury (NSSI) is defined as the direct, deliberate destruction of one's own body tissue without suicidal intent, typically including behaviors such as cutting, burning, or hitting oneself. The risk of engaging in NSSI is particularly high during adolescence. NSSI is associated with impairments in emotion regulation and NSSI behavior serves as an attempt to regulate emotion. We propose to examine whether training adolescents with NSSI to self-regulate using emotion regulation skills to down-regulate hemodynamic activity of the salience network, involved in emotional processing. Moreover, we propose to examine whether limbic-prefrontal cortex connectivity can be increased following neurofeedback, thereby helping adolescents find an optimal way to emotionally regulate with the help of neurofeedback, instead of engaging in NSSI to regulate emotions. We also aim to examine effects of real-time biofeedback by investigating if adolescents can regulate their psychophysiological activity during emotional reactivity with biofeedback. Sixty participants with NSSI will be recruited and offered either real-time functional magnetic resonance imaging (rt-fMRI-NF) (n = 30) or real-time biofeedback (n = 30) training. Participants each each condition will then be randomized to either an active or a control condition (n = 15/group). Participants will take part in three runs of feedback training. Changes in emotional reactivity as measured with facial electromyography (EMG) before and after feedback training will be the proximal outcome measure together with changes of the blood oxygenation level dependent (BOLD) response during real-time fMRI-neurofeedback for the neurofeedback training. Proximal outcome measures for the biofeedback will include psychophysiological measures of emotional reactivity (facialEMG). More distal outcome measures for both neuro- and biofeedback will be measures of NSSI: frequency, methods and severity as well as self-report measures of difficulties with regulating emotions, emotional reactivity and psychiatric symptoms.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| real-time functional magnetic resonance imaging neurofeedback and real-time biofeedback | Experimental | Three sessions of real-time functional magnetic resonance imaging neurofeedback (rt-fMRI-NF) or real-time biofeedback training where participants will receive direct visual feedback from the blood oxygenation level dependent (BOLD) imaging signaling from the salience network in rt-fMRI-NF or visual feeback from a physiological signal in the real-time biofeedback (active condition) |
|
| Sham feedback | Sham Comparator | Three session where participants will be given a yoked sham feedback as control condition. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Real-time functional magnetic resonance imaging Neurofeedback and Real-time Biofeedback | Other | Participants will take part in three runs of real-time functional magnetic resonance imaging feedback (rt-fMRI-NF) training with 4-8 days apart, which will be conducted at the Center for Medical Image Science and Visualization (CMIV) at the university hospital in Linköping. Participants who receive biofeedback will take part in three runs of biofeedback with 4-8 days apart conducted in the lab at the Center for Social and Affective Neuroscience (CSAN) at Linköping university. Participants will be given instructions and basic psychoeducation of brain function and the rational for down-regulating the area of the brain that drives emotion, as well as the physiological reaction that is triggered in response to emotional stimuli. The emotional stimuli are emotional pictures from the International Affective Picture System (IAPS) and the Open Affective Standardized Image Set (OASIS). |
| Measure | Description | Time Frame |
|---|---|---|
| Emotional reactivity | Changes of emotional reactivity is measured with facial electromyography (facialEMG). High zygomatic and corrugator response indicate higher emotional reactivity. | Change from baseline up to 5 weeks |
| Hemodynamic activity | Changes of the blood oxygenation level dependent (BOLD) response during real-time fMRI-neurofeedback for the neurofeedback training. The aim is to down-regulate the hemodynamic activity in the salience network. | Change from baseline at up to 4 weeks |
| Psychophysiological response | Changes of psychophysiological response during the real-time biofeedback training. The aim is to decrease the emotional reactivity and psychophysiological response. | Change from baseline at up to 4 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Nonsuicidal self-injury | Changes of self-reported frequency in nonsuicidal self-injury (NSSI). NSSI frequency is measured using the short 9-item version of the Deliberate Self-Harm Inventory (DSHI). Open ended questions are used for frequency with a range from 0 to several hundreds, depending on participants answers. Higher scores indicate more NSSI frequency and worse outcome. | Change from baseline at up to 5 weeks, and at additional 6 weeks and 3 month follow-up |

| Sham functional magnetic resonance imaging neurofeedback and sham biofeedback | Other | Participants will take part in three runs of sham neurofeedback with 4-8 days apart, which will be conducted at the Center for Medical Image Science and Visualization (CMIV) at the university hospital in Linköping.
