Aim: The use of computerized mental health programs with vulnerable youth, such as early school leavers, remains relatively unstudied. This pilot study examined the feasibility of delivering a computerized cognitive behavioral therapy (cCBT) gaming intervention (SPARX-R) for young people (age 15-20 years) who have left school early and are attending Youthreach, an alternative education (AE) program in Ireland.Method: Students (n = 146) from twenty-one Youthreach Centers were randomized to SPARX-R and no-intervention control. All students within the group were included in the study whether or not they were exhibiting heightened levels of depression. Program impact was examined on both negative and positive indicators of mental health, including depression (primary outcome), generalized anxiety, general mental wellbeing, coping and emotion regulation. Assessments were conducted at baseline and post-intervention (7 weeks). Participants that provided data at post-assessment (n = 66) were included in the analysis.Results: The participants completed on average 5.3 modules of SPARX-R with 30% (n = 9) completing the entire program. A significant improvement in emotion regulation strategies was detected, with expressive suppression decreasing significantly in the SPARX-R group in comparison to the control (-2.97, 95% CI -5.48 to -0.46, p = 0.03).Conclusions: Findings suggest that SPARX-R has a positive impact on emotion regulation. The lack of significant findings on other outcome measures may be attributed to inadequate sample size, and therefore, further research with larger samples are required to establish the effectiveness of the program in reducing depression and anxiety and improving psychological wellbeing among young people attending AE.
