Abstract:As a kind of state-like trait, mindfulness often fluctuates in daily life. Using experience sampling method to measure mindfulness can more easily reflect the core element of "at present" in the concept of mindfulness, which can help reduce recalling bias and obtain the individual's real mental state of mindfulness in daily life. In this study, the Chinese version of the multidimensional state mindfulness questionnaire (MSMQ-C) was developed and tested for reliability and validity. The MSMQ-C was composed of nine items from three dimensions: acting with awareness,present moment attention and nonjudgement, which had good structural validity, criterion-related validity and internal consistency reliability.
