Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised to receive one of two brief 30-minute online single session interventions delivered through the Qualtrics survey software in a Power Point format. Participants will be able to engage with psychoeducational material by engaging in written activities, self-reflection exercises and providing their own feedback and sharing their experiences.
Participants in the intervention group will receive Project SAVE (Stopping Adolescent Violence Everywhere; Dobias et al., 2021) intervention, which focuses on normalising and de-stigmatising feelings of self hatred wit the aim of empowering young adults to select alternative coping strategies in the face of self-hatred. Alternative coping strategies discussed include Dialectical Behavioural Therapy (DBT) distress tolerance skills.
Participants adherence to the intervention will be monitored using website analytics, which will be derived from the Qualtrics software.

Efficacy
Statistical methods / analysis
The results of power analysis indicate that to detect an effect size of 0.40 with a 40% attrition rate from post-intervention to 1-month follow-up, a minimum sample size of 82 participants per group would be required, thus a minimum of 164 participants will be recruited. Data will be analysed using linear mixed models (LMM) using the Statistical Package for the Social Sciences Software. LMM will be performed to evaluate between group changes in clinical outcomes from baseline to end of treatment and 1-month follow up. LMM analyses are robust in handling missing data and unbalanced designs in repeated-measures research, (Nich & Carroll, 1997), offering the benefits of estimation maximization (EM), which provides joint linear modelling for each individual for observed and missing data based on maximizing likelihood for population parameters as a function of observed data (Norusis, 2007). Thus, all participants (regardless of missing data at one or more assessment time points) can be included in the data analyses and linear estimates are obtained, as opposed to missing cases being omitted as is the case with traditional ANOVA techniques (Gueorguieva & Krystal, 2004). Time will be entered as a fixed effect in the model
