Over the past 30 years, mindfulness meditation has made considerable advances under the influence of the development trend of clinical psychology towards non-medical intervention, originally developed by Buddhist practitioners. The most common form in 2007 in the USA was meditation and deep breathing exercise, which accounted for 30% of total nonmedical intervention. The alternative of mindfulness measurement, on the other hand, has been largely neglected, the main reason for which can be identified as the definition of the validation and validity of such measurement. In the present study, 61 mindfulness meditation publications are examined, the purpose being to investigate the usefulness of MAAS in order to detect any possible correlations between MAAS and other mindfulness scales. The purpose of this paper is systematically to review and analyse the validity and reliability of the MAAS questionnaire. In the first part, the development of MAAS is briefly discussed and the way a developed MAAS approach can be used to measure mindfulness under different circumstances is considered. The paper focuses particularly on the definition and framework developed by Brown (2003). In the second part, relevant evaluation through statistical analysis is the focus, concluding with a discussion of the main weaknesses of MAAS and some suggestions for future development of mindfulness measurement. The study will examine only MAAS, and other mindfulness measurements will not be included.
