Meta-analysis of the effectiveness of Acceptance and Commitment Therapy and Mindfulness-Based Cognitive Therapy on test anxiety in students

The present study aimed to conduct a meta-analysis to examine and compare the effectiveness of Acceptance and Commitment Therapy (ACT) and Mindfulness-Based Cognitive Therapy (MBCT) in reducing test anxiety among students. This research employed a meta-analytical approach based on the systematic collection and analysis of data from 24 selected studies out of a total of 63. The study populations included students aged 10 to 18 who received ACT and MBCT interventions in experimental groups. The standardized effect size (Hedges’ g) was used as the primary index for analysis, calculated using Comprehensive Meta-Analysis software version 2. In addition, statistical evaluations included cumulative chart analysis and the assessment of effect sizes across studies to examine data consistency and reliability. The analysis of pre-test and post-test data from both experimental and control groups revealed that ACT and MBCT interventions had a statistically significant impact on reducing test anxiety in the post-test phase compared to control groups. These findings indicate the notable effectiveness of both therapeutic approaches in improving students’ psychological well-being.
