Intersubtest scatter values for the Full, Verbal, and Performance Scales of the WAIS--R were estimated for a sample of 163 psychiatric inpatients and compared with those reported for the WAIS--R standardization group using the normal deviate (z) test. Intersubtest scatter was assessed using the range and the Profile Variability Index. Results were surprising and conflicted with what was expected based on the clinical literature. First, in comparison to the standardization group, the psychiatric inpatients showed significantly more intersubtest scatter on the Verbal Scale only, while Performance Scale values were comparable. Second, the psychiatric inpatient sample, as a group, showed identical amounts of scatter on the Verbal and Performance Scales. Results suggest that the interpretation of intersubtest scatter as a sign of psychopathology should be avoided.
对163名精神病住院患者样本估计了韦氏成人智力量表修订版（WAIS-R）全量表、言语量表和操作量表的分测验间离散值，并使用正态离差（z）检验将其与WAIS-R标准化组报告的离散值进行比较。使用极差和剖面图变异指数评估分测验间离散情况。结果令人惊讶，且与临床文献预期的情况相矛盾。首先，与标准化组相比，精神病住院患者仅在言语量表上表现出显著更多的分测验间离散，而操作量表的值相当。其次，作为一个群体，精神病住院患者样本在言语量表和操作量表上表现出相同程度的离散。结果表明，应避免将分测验间离散解释为精神病理学的标志。
