Development and Testing of imHere4U: A Digital Suicide Prevention Intervention for Cyberbullied Adolescents

The objective of this study is to test the feasibility and preliminary efficacy of Flourish (formerly referred to as imHere4U), a digital suicide prevention intervention for cyberbullied adolescents.

The specific aims are to:

Aim #1: Conduct a randomized controlled trial (RCT) comparing Flourish+Questionnaires vs. Questionnaires Alone among cyberbullied youth at-risk for suicide ages 12-17 (N=80, \>35% underserved youth).

H2a. Primary outcome: Feasibility will be evidenced by recruitment/retention rates \> 80% and imHere4U engagement \> 70%.

H2b. Secondary outcomes: Youth assigned to Flourish+Questionnaires will report improved problem-solving capacity, distress tolerance, and motivation and reduced distress and suicidal ideation than youth assigned to Questionnaires Alone over the 6-month follow-up period.

Exploratory Aim: Examine the feasibility of delivering feedback on online interactions from machine learning algorithms. All youth assigned to Flourish may optionally provide their social media data to receive feedback from machine learning algorithms. H3a. Feedback from algorithms will have high acceptability (identified via qualitative themes and \>70% acceptance rates) and usability, defined by mean scores on Post-Study System and Usability Questionnaire (PSSUQ) \> 6.
