Enhancing Adolescent Self-Esteem: A Pilot Randomized Controlled Trial of the Online Mindfulness-Based Intervention Program (MBSI Online)

Abstract

Objective: This study aimed to develop and assess the effectiveness of the MBSI online program in enhancing self-esteem, mindfulness, and resilience among adolescents, while also evaluating its feasibility and participant satisfaction. Materials and Methods: The MBSI online program is an adapted form of mindfulness-based interventions (MBIs), developed by integrating specific aspects of mindfulness that are related to self-esteem and the core processes of Acceptance and Commitment Therapy (ACT), following consultations with mindfulness experts and program trials. The study enrolled 70 adolescents aged 15 to 18 years with low to moderate self-esteem, from diverse Thai regions. Participants were randomly assigned and equally allocated to intervention and waiting-list control groups. The intervention group underwent an 8-week MBSI online program. Self-esteem, mindfulness, and resilience were assessed at baseline, week 4, week 8, 1 month, and 3 months post-intervention. Results: The self-esteem, mindfulness, and resilience scores within the intervention group have significantly increased over time compared to baseline on week 4, week 8, 1 month, and 3 months post-intervention (p < 0.001). Furthermore, between-group comparisons revealed statistically significant improvements in self-esteem, mindfulness, and resilience (p < 0.05) at corresponding intervals, with medium to large effect sizes. The dropout rate was 25.7%, while participant satisfaction with the MBSI online program was remarkably high, averaging 4.73 out of 5, with 76.9% expressing the highest level of satisfaction. Conclusion: The MBSI online program significantly improved self-esteem, mindfulness, and resilience in adolescents, achieving high participant satisfaction. This program presents a valuable intervention for adolescents with low selfesteem, aiming to prevent psychological issues stemming from diminished self-esteem.
