摘要:Depressive symptoms have an important effect on everyday life. Its development could be associated with a lack of metacognitive skills among other variables. It seems they can be trained by an intervention based in meditation techniques called mindfulness based intervention. The aims of this study were to evaluate 1) the relationship between depressive symptoms, emotional regulation, and metacognitive skills, 2) the effectiveness of an eight-week mindfulness based intervention program on depressive symptoms, metacognition, and emotional regulation in non-clinical population, and 3) the different effect of this intervention on people with presence/absence of clinically significant depressive symptoms. Sixty-seven participants received mindfulness training on a weekly basis during two months. Data on metacognition, emotional regulation, and depressive symptoms was collected one month before the intervention, the first and last day of the intervention, and at 3-month follow up. Significant correlations were found for the total sample and the presence/absence of clinically significant depressive symptoms groups. Differences were found with larger effect sizes in the depressive group (η2 = .73-.99) than in the group with no depressive simptoms (η2 = .41-.70). These results support mindfulness intervention as an effective technique in the alleviation of depressive symptoms and in the improvement of metacognitive skills.
