Current psychological research has paid special attention to the psychological process of continuous monitoring of inner experience, i.e., mindfulness. This study aimed to adapt and to present convergent and divergent validity evidence of a mindfulness self-report measure, the Philadelphia Mindfulness Scale (PMS). Data was based on the answers of 703 Brazilian adults to the adapted version of PMS and three other measures related to self-consciousness and insight. Factorial analysis presented two principal dimensions among the items of PMS, which were related to two components of mindfulness: Acceptance and Awareness. These two dimensions presented internal consistency levels of 0,859 and 0,816, respectively. Convergences among Awareness and data related to self-consciousness taken as self-focus were observed, as well as divergences among Acceptance and maladaptive facets of self-consciousness (Social Anxiety and Rumination). In consonance to the literature on the meditating aspect of mindfulness, Acceptance also presented significant positive correlation with Insight.
