Mindfulness-Based Programs lead to small to moderate reductions in psychological distress among adults, with effects lasting up to six months, according to new research published in Nature Mental Health. The findings shed light on the general effectiveness of these programs and clarify that this effectiveness is not significantly influenced by individual factors such as baseline distress, gender, age, education, or dispositional mindfulness.
The researchers conducted this study to better understand the effectiveness of Mindfulness-Based Programs (MBPs) in preventing mental health issues among adults in non-clinical settings. MBPs are structured courses or training programs designed to teach individuals how to practice mindfulness, which involves paying deliberate and non-judgmental attention to the present moment, enhancing awareness of thoughts, feelings, sensations, and the surrounding environment.
These programs typically incorporate a variety of mindfulness practices, such as meditation, breathing exercises, and body awareness techniques. Participants learn to observe their thoughts and emotions without reacting to them, which can help manage stress, anxiety, and negative emotions. The core idea is to develop a greater sense of self-awareness and improve the ability to respond to life’s challenges in a calm and balanced way.
MBPs are often taught in group settings by trained instructors who guide participants through various mindfulness exercises and discussions. The programs may span several weeks, with regular sessions that gradually introduce participants to different mindfulness techniques and concepts. Despite their popularity, the effectiveness of MBPs has been debated in the scientific community.
To address this, the researchers performed a meta-analysis, a type of study that combines and analyzes data from multiple existing studies to draw more reliable conclusions. They conducted an Individual Participant Data (IPD) meta-analysis, which involves collecting and analyzing the raw data from each participant in each study, rather than just looking at summary statistics. This approach allows for more accurate and detailed analysis of how different factors might influence the effects of MBPs.
They included 13 trials from eight countries, gathering data from 2,371 adults who participated in MBPs. These programs typically consisted of eight-week courses with one to two-hour sessions per week, led by mindfulness teachers. The researchers wanted to find out whether factors like baseline distress, gender, age, education, and dispositional mindfulness could modify the effect of MBPs on reducing psychological distress.
The results of the IPD meta-analysis indicated that, on average, MBPs led to a small to moderate reduction in psychological distress among adults, and this effect lasted for at least six months after the programs. The confidence in these results was high.
“In our previous work it was still not clear whether these mindfulness courses could promote mental health across different community settings,” said lead researcher Julieta Galante, who conducted the research while at the University of Cambridge. “This study is the highest quality confirmation so far that the in-person mindfulness courses typically offered in the community do actually work for the average person.”
Interestingly, the researchers didn’t find clear evidence that the effectiveness of MBPs was influenced by baseline psychological distress, gender, age, education, or dispositional mindfulness.
The study suggests that participating in mindfulness-based programs, which are taught by instructors in a group setting, can be beneficial for adults looking to reduce psychological distress and enhance their mental well-being. However, the researchers also noted that MBPs might not work equally well for everyone, and there are alternative practices and activities that can also contribute to improved mental health.
“We’ve confirmed that if adults choose to do a mindfulness course in person, with a teacher and offered in a group setting, this will, on average, be beneficial in terms of helping to reduce their psychological distress which will improve their mental health,” Galante said. “However, we are not saying that it should be done by every single person; research shows that it just doesn’t work for some people.
“We’re also not saying you should absolutely choose a mindfulness class instead of something else you might benefit from, for example a football club – we have no evidence that mindfulness is better than other feel-good practices but if you’re not doing anything, these types of mindfulness courses are certainly among the options that can be helpful.”
While the study showed positive outcomes, the researchers acknowledged limitations in terms of study designs, the complexity of psychological outcomes, and the potential for biases. They also pointed out that the effects of MBPs on other populations (e.g., older adults or those with lower education) and their comparison with alternative interventions need further investigation.

Jones, and Ian R. White.
