摘要：Mindfulness is a skill that allows the practitioner to expand an existing space between stimulus and response, so he/she may make more conscious choices which in turn prevents the perpetuation of dysfunctional patterns of behaviors, contributing to the improvement of his/her well-being. The goal of this study was to evaluate the psychometric properties of the Brazilian version of the Mindful Attention Awareness Scale (MAAS) in a sample with 395 participants divided into smokers, people from the general population, college students and meditators. They answered the MAAS and the Psychological Well-Being Scale (PWBS). An exploratory factor analysis was conducted to test the factor structure of the MAAS. Internal consistency, test-retest reliability and split half were respectively assessed with Cronbach's α and correlation coefficients. Construct validity was examined by correlating the MAAS with psychological well-being. Criterion validity was assessed by comparing the meditators' scores on the MAAS with the scores of other participants. After the exploratory factor analysis, the Brazilian MAAS remained a unidimensional scale. Reliability [α = .83; split half = .67 and test-retest = .80 (p < .001)] and validity measures were adequate, except the criterion validity which was not confirmed in the mentioned sample.
