MAYSI-2

The MAYSI-2 was developed by Thomas Grisso, Ph.D. and Richard Barnum, M.D., at the University of Massachusetts Medical School during the 1990s with assistance from the William T. Grant Foundation.  It was made available in 2000 after sufficient research had been done to establish initial reliability and validity.  Since 2000, technical assistance for use of the MAYSI-2 nationwide has been provided by the John D. and Catherine T. MacArthur Foundation’s support of the National Youth Screening and Assessment Project (NYSAP) at the University of Massachusetts Medical School.

The MAYSI-2 is a paper-and-pencil self-report inventory of 52 questions designed to assist juvenile justice facilities in identifying youths 12 to 17 years old who may have special mental health needs. Youths circle YES or NO concerning whether each item has been true for them "within the past few months." Youths read the items themselves (5th grade reading level) and circle the answers. Administration takes about 10 to 15 minutes and scoring requires approximately 3 minutes. The MAYSI-2 is available in both English and Spanish as well as in software form. The MAYSI-2 software, called MAYSIWARE (2006) and MAYSIWARE 4.0 (2011, for Vista/7 versions of Windows), is available for purchase from Professional Resource Press.

MAYSI-2 Research Review

This review identifies all published research reports and dissertations through September 2011 that have evaluated or used the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2).  The review describes the results of studies using the  MAYSI-2 to examine demographic groups, the psychometric properties of the tool, correlations with similar measures, and the relation of MAYSI-2 scale scores to behavioral, clinical and offense characteristics of young people admitted to juvenile justice programs.  The review also offers cautions for clinical and research use of the instrument, as well as suggestions for future research that could improve clinical use of the MAYSI-2 in mental health screening in juvenile justice settings.    

MAYSI-2 Reliability & Validity Research Studies

Substantial research supports the reliability and validity of the MAYSI-2 when used in the settings for which it was intended, on the target populations for which it was developed, and administered in the manner recommended by the authors.  The link below offers a compilation of research studies that have been performed using the MAYSI-2 in a variety of settings and with a variety of populations.  As with any psychological instrument, the reliability and validity will vary depending on how, where, and with whom the measure is used.
