Abstract

The VRPMT was administered to 44 individuals with first-episode schizophrenia. The test was administered again 2 weeks later to establish test-retest reliability. The concurrent validity of the VRPMT was evaluated by examining the correlations between the VRPMT score and the score on the Chinese version of the Cambridge Prospective Memory Test (CAMPROMPT-CV). The performance of individuals with schizophrenia on the VRPMT was also compared with that of 42 healthy control subjects to examine the test’s sensitivity and specificity. The intraclass correlation for test–retest reliability of the total VRPMT–CV score was 0.78 (p = .005). A significant correlation was found between the total VRPMT-CV score and the total CAMPROMPT-CV score (r = 0.90; p < .001). Comparison with the healthy control subjects revealed that the total VRPMT-CV score was a sensitive (92.9%) and specific (75%) measure of prospective memory deficits in individuals with schizophrenia. The VRPMT-CV is an assessment of prospective memory that has good construct validity, test–retest reliability, sensitivity and specificity in the context of first-episode schizophrenia.
