Discriminant function and polynomial regression methods were used to define a mental age function from scale score profile patterns found in the WAIS manual. Values on the mental age function then were calculated from WAIS scale score profiles for 164 alcoholics in the age range 35 to 74. Validity of the mental age function was evident in clear discrimination between chronological age groups in the alcoholic sample. As compared with WAIS normative values for the mental age function, the mean mental age for patients in the alcoholic sample was advanced approximately 7 years over age-matched normals. Unweighted means ANOVA revealed the accelerated mental aging of alcoholic patients to be statistically significant. This finding is discussed in the context of other research that supports a premature aging hypothesis.
判别函数和多项式回归方法被用于根据韦氏成人智力量表（WAIS）手册中的量表分数剖面图模式来定义心理年龄函数。然后，根据年龄在35至74岁之间的164名酗酒者的WAIS量表分数剖面图计算心理年龄函数的值。心理年龄函数的有效性在酗酒样本中不同实足年龄组的明显区分中得以体现。与WAIS心理年龄函数的常模值相比，酗酒样本中患者的平均心理年龄比年龄匹配的正常人提前了约7岁。非加权均值方差分析显示，酗酒患者心理衰老加速具有统计学意义。这一发现是在支持早衰假说的其他研究背景下进行讨论的。
