The primary aim of the proposed Randomised Control study is to investigate the effects of a socially assisted robot (i.e. Purrble) on emotional regulation difficulties (measured by DERS8) with young LGBTQ+ people who have self-harmful (with or without suicidal intention) (in comparison to a wait-listed control). Secondary aims include investigating the effects of the Purrble on young people's self-harmful thoughts, symptoms of anxiety and depression, alongside quantitative and qualitative (interviews) measures of engagement with the intervention.
Self-harm is a key concern among young people, this is highlighted by the rising rates self-harm and suicide attempts in recent years. Internationally, young LGBTQ+ people are recognised to report higher prevalence of self-harmful thoughts, behaviours, anxiety and depression than their cisgender, heterosexual peers. Emotion regulation (ER) is known to be a transdiagnostic risk factor, which is widely associated with higher risk of self-harm. Typically, LGBTQ+ populations also report greater difficulties with ER which partially explains association with self-harm. While LGBTQ+ youth are frequent users of digital technologies and digital interventions are often considered feasible and acceptable, there is limited evidence of the effectiveness of such within these populations. Currently, there is no evidence-based digital interventions targeting LGBTQ+ youth who struggle with self-harm. To address this gap, the investigators have conducted a small pilot study (n=21) to evaluated one such possible tool - Purrble - as a means to offer in-the-moment emotional support for those with high levels of self-harm risk (high symptoms of anxiety, depression, or self-harmful experiences in the last 6 months). The goals of the study centre around testing the feasibility, acceptability, and usage of Purrble across a 2-week deployment period. These results have been promising, indicating Purrble as a feasible and acceptable intervention, alongside indicators of clinical value during Purrble deployment: i) reduction of anxiety and depression symptoms during deployment and ii) reduced prevalence of self-harm thoughts. From previous interviews, participants highlighted the positive outcomes which were associated with Purrble use (stopping them reaching the point of thinking about self-harm, being a barrier to self-harm behaviours, and encouraging emotional regulation coping strategies; e.g. grounding, self-soothing). However, these pilot studies did not include a controlled waitlist group, and thus more rigorous investigation of these promising effects is needed - leading to the current study.
Study Type
INTERVENTIONAL
When the Purrble is picked up, it emits a frantic heartbeat that slows down if the person uses calm stroking movements. If the Purrble is soothed for long enough, it transitions into a purring vibration indicating a calm, content state. Logic model underlying the intervention: Level 1: in-the-moment soothing support to young people in emotional moments when they would attempt to utilise emotion regulation (ER) strategies to calm down. Level 2: mechanisms that facilitate long-term engagement with the intervention, building on positive subjective experience of Level 1. Level 3: shift in young peoples' ER practices and implicit beliefs about emotion, after repeated experience of Levels 1-2. * see JMIR Res Protoc 2021;10(11):e28914 (doi: 10.2196/28914)

Emotion regulation (DERS8)
Across the trial, we hypothesise that access to the Purrble intervention (compared to the waitlist control) will lead to a decrease in self-reported difficulties with emotion regulation as measured by the primary outcome (DERS8). We will compare the DERS8 assessment pre-deployment (calculated as the average of DERS scores across baseline weeks 1-3) and final deployment assessments (averaged across weeks 11-13). Measured by: Difficulties with Emotional Regulation Scale-8 (DERS8), an 8-item instrument used to measure or assess the difficulties with regulating emotion \[22\]. The DERS8 score is calculated using a 5-point Likert scale, ranging from 1 (almost never, 0-10%) to 5 (almost always 91-100%). These scores are added together to form a total score (8-40). Higher scores indicate greater levels of difficulty associated with response to situations eliciting negative emotions.
Time frame: all timepoints [Time Frame: Three times during pre-deployment (week 1-3) and ten times during the 10-week long deployment period (week 4-13) = total of 13 times]
Self-harmful thoughts (SHQ)
A secondary aim to evaluate the impact of the Purrble intervention on young LGBTQ+ people's self-harmful ideation (with and without suicidal intention), compared to waiting list controls. Measured by: The Self-Harm Questionnaire (SHQ; \[23\]). While the whole instrument is used at baseline (T0), offering a greater level of detail as to why someone has self-harmed, and only the three screener items will be used across deployment. These question the presence of self-harmful thoughts (without suicidal intentions), suicidal thoughts, and whether the young person has harmed themselves on purpose. The screener assigns scores of 1 (no), 2 (yes, once), 3 (yes, two, three or four times), and 4 (yes, five or more times) - offering a general idea of frequency of self-harmful thoughts.
Time frame: all timepoints [Time Frame: Three times during pre-deployment (week 1-3) and ten times during the 10-week long deployment period (week 4-12) = total of 13 times]
Anxiety (GAD7)
A secondary aim is to investigate the effects of Purrble on reports of anxiety symptoms within young LGBTQ+ people who have current experiences of self-harmful ideation (in comparison to a wait-listed group). Measured by: Generalised Anxiety Disorder Assessment (GAD-7; \[24\]), a seven-item instrument that is used to measure or assess the severity of generalised anxiety disorder. Each item asks the individual to rate the severity of their symptoms over the past two weeks. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of "not at all," "several days," "more than half the days," and "nearly every day," respectively, and then adding together the scores for the seven questions (score range: 0-21). Scores of 5, 10, and 15 represent cut-points for mild, moderate, and severe anxiety, respectively.

Depression (PHQ-9)
A secondary aim is to investigate the effects of Purrble on reports of depressive symptoms within young people who have current experiences of self-harmful ideation (in comparison to a wait-listed group). Measured by: Patient Health Questionnaire-9 (PHQ-9; \[25\]) , a depression module which scores each of the nine DSM-IV criteria as "0" (not at all) to "3" (nearly every day). It is not a screening tool for depression but it is used to monitor the severity of depression and response to treatment. The maximum score is 27 (9 questions x maximum 3 points per question). Depression severity is graded based on the PHQ-9 score: None 0-4 Mild 5-9 Moderately 10-14 Moderately severe 15-19 Severe 20-27.
