The Wide Range Achievement Test (Revised) (WRAT-R) reading test, demographic variables and drug use severity were used to develop prediction equations to estimate premorbid ability in 92 cocaine abusers. WRAT-R reading was correlated significantly with full scale, verbal and performance IQ. Stepwise regression indicated that only WRAT-R reading score and age accounted for 23% of the variance in Full Scale IQ (FSIQ) and 28% in Verbal IQ (VIQ). Abstinence and severity of use variables did not correlate with nor predict IQ. Actual and predicted IQ scores were correlated significantly and did not differ based on within group t-tests. Thus, these formulas accurately estimate premorbid functioning in cocaine-dependent research patients with FSIQs in the average to low average range, replicating the results in normal adults with average IQs.
使用广泛成就测验（修订版）（WRAT-R）阅读测试、人口统计学变量和药物使用严重程度来建立预测方程，以估计92名可卡因滥用者的病前能力。WRAT-R阅读与全量表、言语和操作智商显著相关。逐步回归表明，只有WRAT-R阅读分数和年龄可解释全量表智商（FSIQ）中23%的方差变异以及言语智商（VIQ）中28%的方差变异。戒断情况和使用严重程度变量与智商既无相关性也无法预测智商。实际智商分数和预测智商分数显著相关，且在组内t检验中无差异。因此，这些公式能够准确估计平均智商至低平均智商范围内可卡因依赖研究患者的病前功能，这与智商处于平均水平的正常成年人的研究结果一致。
