This study examined neuropsychological functioning in a heterogeneous population of persons who were homeless (N = 60) and compared the value of the Abbreviated Halstead-Reitan Test Battery with the Mini-Mental State Exam (MMSE). A high incidence of neuropsychological dysfunction was evident with 80% of patients showing impaired test battery performance and 35% showing an impaired MMSE. Performance on the Trail Making Test, Part B was especially impaired. Patients impaired on Trails B more often showed impaired test battery performance, suggesting it may be a better screening tool than the MMSE. Neuropsychological performance was not significantly affected by the patients' gender, age, diagnosis, or past psychiatric and medical history. Regression analysis suggested that 29% of the variance in test battery performance was accounted for by the patients' education. Results support previous findings that large numbers of people who are homeless are neuropsychologically impaired; this should be considered when planning treatment and rehabilitation.
