Abstract

Background. Psychological distress is a progressive health problem that has been linked to decreased quality of life among university students. This meta-analysis reviews existing randomized controlled trials (RCTs) that have examined the effects of mindfulness-based stress reduction (MBSR) on the relief of psychosomatic stress-related outcomes and quality of life among university students. Methods. The PubMed, EMBASE, Web of Science, PsycINFO (formerly PsychLit), Ovid MEDLINE, ERIC, Scopus, Google Scholar, ProQuest, and Cochrane Library databases were searched in November 2023 to identify the RCTs for analysis. Data on pathology (anxiety, depression, and perceived stress), physical capacity (sleep quality and physical health), and well-being (mindfulness, self-kindness, social function, and subjective well-being) were analyzed. Results. Of the 276 articles retrieved, 29 met the inclusion criteria. Compared with control therapies, the pooled results suggested that MBSR had significant effects, reducing anxiety (SMD = −۰٫۲۹; ۹۵% CI: −۰٫۴۹ to −۰٫۰۹), depression (SMD = −۰٫۳۲; ۹۵% CI: −۰٫۶۲ to −۰٫۰۲), and perceived stress (SMD = −۰٫۴۱; ۹۵% CI: −۰٫۶۰ to −۰٫۲۹) and improving mindfulness (SMD = ۰٫۳۴; ۹۵% CI: 0.08 to 0.59), self-kindness (SMD = ۰٫۵۷; ۹۵% CI: 0.30 to 1.12), and physical health (SMD = −۰٫۵۹; ۹۵% CI: −۱٫۱۴ to −۰٫۰۴). No significant differences were observed in sleep quality (SMD = −۰٫۲۰; ۹۵% CI: −۰٫۰۶ to 0.20), social function (SMD = −۰٫۷۱; ۹۵% CI: −۲٫۴۰ to 0.97), or subjective well-being (SMD = ۰٫۰۷; ۹۵% CI: −۰٫۱۸ to 0.32). The quality of the evidence regarding sleep quality and physical health outcomes was low. Conclusions. MBSR therapy appears to be potentially useful in relieving functional emotional disorders. However, additional evidence-based large-sample trials are required to definitively determine the forms of mindfulness-based therapy that may be effective in this context and ensure that the benefits obtained are ongoing. Future studies should investigate more personalized approaches involving interventions that are tailored to various barriers and students’ clinical characteristics. To optimize the effects of such interventions, they should be developed and evaluated using various designs such as the multiphase optimization strategy, which allows for the identification and tailoring of the most valuable intervention components.

Introduction

Mindfulness therapy is a standardized psychological intervention that aims to reduce stress, encourage mindful thinking habits, and allow recipients to manage difficult emotional processing. It focuses on the concentration of one’s attention in the moment, nonsubjective judgment, and openness to accepting personal experience and involves corresponding behavioral training, such as attention training, body scanning, and sitting meditation [1]. Previous research on psychological interventions has found that mindfulness therapy can help reduce stress among university students and affects their overall quality of life and the psychological functions to which they adapt [2].

The theoretical support and the understanding of the operating mode are reasonable but still have differences. Thus, the mental health benefits, potential effects, and limitations of mindfulness therapy for university students warrant further examination. Although education and social support can be effective in preventing and treating the underlying psychological problems among university students with poor mental health, such interventions do not always affect or improve psychological well-being [3, 4].

The most prevalent psychological symptoms among university students are anxiety, mental stress, and emotional distress, which can result in decreased functioning in the context of academic and interpersonal stress. Global mental health surveys conducted by the World Health Organization (WHO) indicate that mental disorders are highly prevalent among university students, with 12-month prevalence rates ranging from 20.3% to 45% of university students over the age of 18 [5–۷]. The prevalence rates of insomnia, depressive symptoms, and anxiety symptoms were 37.80%, 48.20%, and 36.70%, respectively, among Chinese university students during the COVID-19 pandemic [8]. In a randomized controlled trial with 11,169 university students conducted by the WHO, students had increasing intentions to use mental health services: The results indicated lifetime use rates of 12.6% and 7.3% for psychotherapy and medication for emotional problems, respectively. Suicidal thoughts and behaviors and nonsuicidal self-injury within the preceding 12 months were also common, with 21.1% of students in the sample reporting suicidal ideation, 10.6% reporting suicide plans, 0.4% reporting suicide attempts, and 6.8% reporting nonsuicidal self-injury [5]. Furthermore, one previous study found that high-compliance mental health services had a significant effect on students’ intention to seek mental health services in the next semester [9–۱۱].

Results

۳٫۱٫ Description of Studies
A total of 276 studies items were initially obtained through the database search. Using NoteExpress, 193 deduplicated studies were obtained, and the remaining 220 items were obtained. After reviewing their titles and abstracts, 135 studies that were of incompatible research types were excluded. A total of 13 articles were further excluded after reading the full text, and the remaining 29 studies [24–۵۳] were retained for data extraction. The baselines of the trials were comparable. The literature search process and results are shown in Figure 1.
