【摘要】 目的 :探讨Hiscock必选数字记忆测验对伪装记忆缺损的作用 ,并确定该测验判定伪装记忆缺损的划界分。方法 :以 6 6名不同损伤程度的非赔偿性脑外伤患者及 2 4名赔偿性脑外伤伴有伪装智力低下者为研究对象 ,并与 5 8名正常人作对照 ,对各组的必选数字记忆测验结果进行方差分析、计算累计百分率 ,并对伪装划界分作判定分析。结果 :伪装组回答正确数与对照组及 3个非伪装组之间差异均有非常显著性 ;容易条目的回答正确数小于等于 11,或者困难条目的回答正确数小于等于 7,可判定为伪装。判定的总正确率为 98.6 % ,假阳性率为 1.4%。结论 :必选数字记忆测验是鉴别伪装记忆缺损的有效的评定工具。更多还原

【Abstract】 Objective:To explore the validity of Hiscock and Hiscock’s Forced-Choice Digit Memory Test (HDMT) in detecting dissimulation of memory deficit. Methods: Group comparisons were conducted. The performance of 24 subjects with compensation were compared to that of 66 subjects without compensation and 58 normal controls. Results: There were a significant differences between dissimulating group and other groups. The accuracy of distinction was 98.6% when the cut off scores of HDMT was 11 for easy items and 7 for difficult items. Conclusion: HDMT was useful for detecting true memory deficit as well as dissimulation.更多还原
