摘要
病前智力的估计是甄别、诊断智能衰退的必要条件,有重要的临床和科研意义。依据学业成绩和工作成就等背景资料可综合评估病前智力的水平与结构,但其定性的结论不利于科研,且难免主观。依赖人口统计学变量的回归公式能客观给出确切的、具有一定效度的估计数,但会高估或低估极端智商。依据当前测验成绩的估计有“保持”和最佳作业两种模式,这种估计个体特异高,但被试在选用测验上的当前表现能否代表病前智力水平尚有争议。联合不同方法能提高预测效度。
Estimation of premorbid intelligence is imperative to detect general cognitive decline and therefore it is important to both research and clinical work. Several estimating approaches were introduced. Qualitative estimation based on intelligence-related background such as educational records and occupational achievements can assess premorbid intelligence comprehensively, however, its objectivity is suspected. On the other hand, objective and quantitative estimation based on regression equation of demographic variables inevitably overestimates or underestimates extreme IQs. Approaches depended on 慼old?test or best performance are more individual-specific while their premise is questioned. Combining different approaches can improve predictive validity.
