A recent systematic review and meta-analysis has studied the impact of mindfulness-based interventions applied to children with autism spectrum disorders. We discuss the findings and limitations of the research.
Although the results are promising, the meta-analysis has important limitations: the number of studies is low, and some measures have been made on a very small number of available comparisons. Furthermore, the studies are short-term with little follow-up, which does not allow for longer-term evaluations of the effectiveness of the intervention. In addition, there is significant heterogeneity in the design, controls, intensity, and type of intervention, as well as in the clinical severity of ASD, which was not always reported. Considering their low cost and ease of implementation, mindfulness-based interventions represent a promising option for ASD. However, further controlled clinical trials are still needed to more precisely define their benefits.
PATHOPHYSIOLOGY AND MECHANISMS
Autism spectrum disorder (ASD) is a condition caused by biological and environmental factors during neurodevelopment, forming a spectrum of symptoms that include sensory alterations, difficulties in affective regulation, neurocognitive impairments in social cognition, communication, metacognition, central coherence, etc., which often result in restricted behavior patterns and repetitive behaviors. The diagnosis of autism and the child's adaptive difficulties can additionally generate psychological symptoms in parents. Mindfulness-based interventions are practices that combine mindfulness meditation and various metacognitive, experiential, and emotional regulation exercises, among others. At the neurobiological level, mindfulness has been shown to induce functional and structural changes in brain areas involved in emotional and stress regulation, such as the prefrontal cortex, hippocampus, and amygdala. These interventions also modulate the hypothalamic-pituitary-adrenal axis, decreasing physiological reactivity to stress. On the other hand, they can be used within psychotherapeutic frameworks (MBCT, acceptance and commitment therapy, etc.), making them an easily implementable practice that is beneficial for people with autism as well as their caregivers.STUDY
A recent systematic review and meta-analysis (Peng et al., 2025) analyzed the effectiveness of mindfulness-based therapies in more than 600 participants from 12 randomized controlled trials. The participants were children diagnosed with autism and parents of children with autism. Interventions included structured mindfulness programs in different contexts, such as mindfulness-based cognitive therapies (MBCT), acceptance and commitment therapies, meditation with yoga, etc. The programs varied in length, from six weeks to six months, and in frequency, usually with sessions lasting between 30 and 90 minutes each. Control groups received usual treatment, general information, or no specific intervention. The variables assessed in the children included scales of problem behaviors, emotional difficulties, and social response, and in the parents, they included parental stress, anxiety-depressive symptoms, mindfulness, and psychological resilience.MAIN RESULTS
The interventions showed an improvement in social response and a tendency toward a reduction in externalizing problem behaviors, although the latter is at the threshold of significance (P = 0.05) based on only two comparisons, which requires further study. Emotional and behavioral difficulties did not reach significance, although there were a low number of comparisons. A significant reduction in parental stress was observed in parents, and a decrease in anxiety-depressive symptoms in caregivers. Other measures come from a low number of comparisons, such as psychological resilience or mindfulness, requiring further studies. The sample size did not allow for adequate analysis of the mediating impact of variables such as age or ASD severity, limiting the overall interpretation of the findings.CONCLUSION AND CLINICAL RELEVANCE
This meta-analysis suggests that mindfulness-based interventions may be useful as a complementary practice to the general management of ASD. Children with ASD show benefits in social response, suggesting improvement in certain neurocognitive aspects and affective regulation, potentially improving aspects such as attention, impulsivity, withdrawal, etc., with a potential impact on social adaptation. The reduction of negative affective symptoms such as stress and anxiety in parents and caregivers could contribute not only to greater personal well-being but also to creating a more stable and secure environment for the child, promoting behavioral and psychosocial adaptation. The increase in mindfulness observed in the meta-analysis may have important clinical relevance by reducing reactivity to problematic behaviors and improving interactions between the two.Although the results are promising, the meta-analysis has important limitations: the number of studies is low, and some measures have been made on a very small number of available comparisons. Furthermore, the studies are short-term with little follow-up, which does not allow for longer-term evaluations of the effectiveness of the intervention. In addition, there is significant heterogeneity in the design, controls, intensity, and type of intervention, as well as in the clinical severity of ASD, which was not always reported. Considering their low cost and ease of implementation, mindfulness-based interventions represent a promising option for ASD. However, further controlled clinical trials are still needed to more precisely define their benefits.
