Abstract:
Objective To explore the reliability and validity of the computerized Chinese version of Cambridge Prospective Memory Test (C-CAMPROMPT) for assessment of prospective memory (PM) in chronic schizophrenia patients. Methods 50 patients and 50 healthy controls formed the study sample. PM performance was measured with computerized C-CAMPROMPT, while the Wechsler Adult Memory Scale-Forth Edition (WMS-IV), Wisconsin Card Sorting Test (WCST) and Category Fluency Test (CFT) were administered to assess logical memory (LM), visual representation (VR), executive function and processing speed. Results The test- retest reliability (0.981, P<0.001), split half reliability (0.627, P<0.001) and internal consistency reliability (0.742) of C-CAMPROMPT were satisfied. The scores of C-CAMPROMPT and its subtest in schizophrenia were lower than that in healthy control (P<0.001). The performance of PM in patients with schizophrenia closely related to the scores of LM, VR, WCST-CC and CFT (r=0.34~0.89, P<0.05). The sensitivity (86%) and specificity (92%) of the scale were satisfied. Factor analysis extracted 2 factors. Conclusion The computerized C-CAMPROMPT shows a good reliability and validity for assessment of PM function in chronic schizophrenia, and is a sensitive, adaptable, stable instrument.
