Plain language summary
Research in the field of the mind is increasing, with students becoming key objects of study in the field of social sciences and health. The main aim of this study was to review the scientific literature in order to analyze the effect produced by cognitive-behavioural programs and meditation strategies on stress, anxiety, and depression in students. A secondary aim was to identify the determinants of treatment success. This study is a systemic review and meta-analysis of 34 articles which included 3296 participating students. A total of 22 effect sizes were calculated for stress treatment, 28 for anxiety and 28 for depression. Results show that interventions based on cognitive-behavioural programs, self-reflection, and mindfulness-based approaches produce satisfactory and significant results in relation to the reduction of stress, anxiety, and depression in students. Furthermore, taking into consideration the theoretical foundations of the studies analysed, meditation (mindfulness, yoga and tai chi), muscle relaxation and breathing, coaching, and cognitive-behavioural therapy are strategies that have shown effectiveness in improving mental health. Authors conclude that it is essential to focus attention on how to improve the mental health of students, including an increase in the number of interventions in the classroom.
Abstract
The prevalence of mental health problems within students due to high academic demands and learning difficulties is a current challenge the field of education. The aim of this study is to review the scientific literature in order to analyze the effect produced by cognitive-behavioral programs and meditation strategies on stress, anxiety, and depression in students. A further aim is to identify the determinants of treatment success. The bibliographic search was carried out using Web of Science, specifically in the categories of "Education and Educational Research" and "Psychology", obtaining a sample of 122 articles published between 2007 and 2018. Studies were included which had a pre-experimental or quasi-experimental design and included pre-test and post-test phases. Following application of inclusion criteria, 34 articles were selected for inclusion in a meta-analysis of the random effects of each variable. This obtained an average effect size of -0.41 for stress, -0.37 for anxiety, and -0.30 for depression. Three moderating variables were analyzed, with significant correlations being found for the type of treatment relating to stress (Q = 11.01, df = 2, p = 0.004, R2 = 0.294) and depression (Q = 6.14, df = 2, p = 0.048; R2 = 0.436). The stage of education of the individuals was also found to impact upon anxiety intervention success (Q = 13.093 df = 2, p = 0.0009, R2 = 0.196). Interventions mainly addressed the importance of meditation strategies, mindfulness programs, and cognitive-behavioral therapy to reduce stress, anxiety, and depression in students. This supports the need to increase research at an early age, considering the treatment of mental health as a key factor influencing academic performance and quality of life.
