Used partial correlation and multiple regression procedures to test the hypothesis that the PPVT IQ assesses more than vocabulary in adults. Ss were 84 inpatients from psychiatry and neurology wards. The relationships between the PPVT IQ and other measures of vocabulary, intelligence, memory, visual-motor speed and education were examined in the statistical analyses. Although these variables have significant simple correlations with the PPVT IQ, the multivariate analyses show that the Vocabulary Subtest of the WAIS-R is the only important variable. No other variable or variable combinations are able to account for further PPVT IQ variance after the effect of the Vocabulary Subtest is removed. The results support the use of the PPVT as a test of adult vocabulary, but not adult intelligence, and suggest that the PPVT may be useful as part of language assessment in patients with expressive language disorders.
皮博迪图片词汇测验智商（PPVT IQ）对成人的评估不仅仅局限于词汇。研究对象为来自精神病科和神经科病房的84名住院患者。在统计分析中，考察了PPVT IQ与其他词汇、智力、记忆、视觉运动速度及教育程度测量指标之间的关系。尽管这些变量与PPVT IQ存在显著的简单相关性，但多元分析表明，韦氏成人智力量表修订版（WAIS-R）的词汇分测验是唯一重要的变量。在去除词汇分测验的影响后，没有其他变量或变量组合能够解释PPVT IQ的进一步变异。结果支持将PPVT用作成人词汇测试，但不支持将其用作成人智力测试，并表明PPVT作为表达性语言障碍患者语言评估的一部分可能是有用的。
