The aim of this research is to develop and validate a self-report measure of mindfulness and coping, the mindful coping scale (MCS). Dimensions of mindful coping were theoretically deduced from mindfulness theory and coping theory. The MCS was empirically evaluated by use of factor analyses, reliability testing and nomological network validation. The study's participants were high school students from two high schools, covering all streams. Further validation was obtained by correlating the MCS-subscales with an appraisal theory-based measure of coping strategies. Results from factor analyses supported the proposed measurement model and Cronbach's alphas indicated good internal consistency for the four sub-scales. Furthermore, correlations with instrument for measuring coping were mainly in accordance with our expectations. The above supports the validation of our instrument. (Contains 2 notes and 3 tables.)
