| Abstract: | The purpose of the present study is to examine the test-retest reliability of the Halstead-Reitan Battery (HRB) in an acutely psychotic population. Ten acutely psychotic patients, initially tested upon admission to an inpatient unit of the Austin State Hospital, were selected for retesting on the basis of showing the most complete remission of psychotic symptoms of all patients tested over the 14-month period from June 1978 to August 1979. Only patients showing good remission were selected in order to maximize the potential for changes in test performance to occur and, thus, provide a conservative estimate of test-retest reliability. The average retest interval was 10.4 weeks (SD=6.67), with retest being completed just prior to discharge. Reliability was examined for each HRB subtest across subjects, as well as for each subject across subtest. While the patients generally showed an improved performance at retest, the reliability of the HRB was relatively high. |
