Abstract: Reviews the development, validity, and potential uses of the Wisconsin Manual for Assessing Psychotic-like Experiences (WMAPE; L. J. Chapman and J. P. Chapman, 1980), and provides an interview schedule for collecting information required to make the ratings. The WMAPE is an interview-based assessment system for rating psychotic and psychotic-like symptoms on a continuum of deviancy from normal to grossly psychotic. The original manual contained 6 scales, assessing thought transmission, passivity experiences, thought withdrawal, auditory experiences, personally relevant aberrant beliefs, and visual experiences; a 7th scale assessing deviant olfactory experiences was subsequently added. The scales have good interrater reliability when used by trained raters. Cross-sectional studies have shown that the frequency and deviancy of psychotic-like experiences are elevated among college students who were identified, hypothetically, as psychosis prone by other criteria. Psychotic-like experiences of moderate deviancy in college students successfully predicted the development of psychotic illness and poorer overall adjustment 10 yrs later. The WMAPE is useful for identifying psychosis-prone individuals and is recommended for use in linkage and treatment outcome studies. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
