The Mindfulness-Based Cognitive Therapy (MBCT) is a well-known intervention programme that has proven to be efficient in management of emotional and psychological problems through active, purposive and non-judgemental awareness of experiences. The present study aims to evaluate relative efficiency of MBCT in improving resilience and well-being of children of deployed military soldiers. The sample of the study comprised of N=88 students (44 males and females each) from Army school of Central India. The age range of participants was 14-17 years. Using non-randomized control group pre-test post-test design, after pre-test, the participants were randomly assigned to two equal groups (44 participants each) comprising of equal number of boys and girls. The Experimental Group (Mage=15.14, SD=1.11) received MBCT sessions for 8 weeks while the Control Group (Mage=15, SD=.96) in parallel, received weekly Psycho-education sessions. The post-assessment was conducted on n=38 Experimental group and n=35 Control group participants respectively. Post-test results showed a greater improvement in resilience and well-being of Experimental group participants as compared to the Control group. The improvement was observed to be specific to those participants with initial pre-test scores falling below 75th percentile. The magnitude of this effect was found to be significant. The findings support that MBCT is effective in improving stress tolerance and coping and can lead to an improved overall functioning of military children. The findings can prove to be helpful for effective management of academic and non-academic stress and enhancement of the quality of remedial programmes.
