The impact of a brief mindfulness training on interoception: A randomized controlled trial

Area of Science:

• Neuroscience
• Psychology
• Mindfulness Studies

Background:

• Interoception, the perception of internal body signals, is crucial for emotion regulation and implicated in affective disorders.
• Mindfulness meditation practices are increasingly linked to improved interoceptive processes.
• Dysfunctional interoception is a potential factor in various mental health conditions.

Purpose of the Study:

• To investigate the effects of a brief, three-day mindfulness training on interoceptive accuracy and sensibility in healthy adults.
• To explore the mediating role of interoceptive sensibility in the relationship between mindfulness training and anxiety reduction.

Main Methods:

• Randomized controlled trial with 40 healthy adults naive to mindfulness practices.
• Intervention group received a three-day mindfulness training (MT); control group received active control.
• Assessment of interoception and anxiety levels before and after the intervention.

Main Results:

• Mindfulness training significantly increased interoceptive sensibility, with improvements in five subdomains.
• No significant changes in interoceptive accuracy were observed post-training.
• Interoceptive sensibility changes mediated the reduction in anxiety state following mindfulness training.

Conclusions:

• A brief mindfulness training can enhance interoceptive sensibility in healthy young adults.
• This study provides evidence for interoceptive sensibility as a mechanism underlying the anxiolytic effects of mindfulness meditation.
• Findings suggest mindfulness practices may be a valuable tool for improving emotion regulation through enhanced interoception.
