This study examined the construct and criterion validity of the Mindful Attention Awareness Scale (MAAS) in cancer outpatients, using matched community members as controls.


Cancer outpatients (n=122) applying for enrollment in a mindfulness-based stress reduction (MBSR) program completed the MAAS and measures of mood disturbance and stress. Local community members (n=122) matched to the patients on gender, age, and education level completed the same measures.


The single-factor structure of the MAAS was invariant across the groups. Higher MAAS scores were associated with lower mood disturbance and stress symptoms in cancer patients, and the structure of these relations was invariant across groups.


The MAAS appears to have appropriate application in research examining the role of mindfulness in the psychological well-being of cancer patients, with or without comparisons to nonclinical controls.
