School-based interventions that focus on enhancing self-awareness could help achieve these goals. The aim of this research project was to create an overview of what kind of interventions effectively enhance self-awareness and offer insight into possible moderators and implementation practices. A systematic search was performed: 41 studies were systematically reviewed, and 28 studies were included in a meta-analysis. The mean effect size was statistically significant and showed a small to moderate, positive, pooled effect (Hedge’s g = .307). Statistical heterogeneity was high, yet gender and the mental health-status of participants did not explain the variance in the effectiveness between the interventions in this study sample. From the included studies, 13 interventions showed significant, positive effects. Most of these interventions utilized a SEL-framework or mixed different theoretical backgrounds and techniques. Findings suggested that interventions seem to thrive when implemented with a whole-school approach: integrated in school-curricula on an ongoing basis, executed by teachers when used with a universal approach, with family involved, and health practitioners engaged to offer support and guidance to school-staff and teachers.Show less
