This study investigated the relationships among the Peabody Picture Vocabulary Test-Revised (PPVT-R) alternate forms and, also, the relationship of each PPVT-R form with the Wechsler Adult Intelligence Scale-Revised (WAIS-R) for a referred sample of 60 adult clients of the California State Department of Rehabilitation. Clients ranged in age from 18-3 to 37-7 (M = 25-7, SD = 5-9). PPVT-R alternate forms r = .88 was significant at p less than .001. Correlations with the WAIS-R VIQ were .82 for L, .78 for M; with PIQ, .46 for L, .38 for M; with FSIQ, .77 for L, .67 for M. All correlations with both forms of the PPVT-R were significant. PPVT-R mean scores did underestimate significantly all WAIS-R mean scores. Implications are discussed.
本研究调查了皮博迪图片词汇测验修订版（PPVT-R）不同版本之间的关系，以及每个PPVT-R版本与韦氏成人智力量表修订版（WAIS-R）之间的关系，研究对象为加利福尼亚州康复部转介的60名成年客户。客户年龄范围为18岁3个月至37岁7个月（M = 25岁7个月，SD = 5岁9个月）。PPVT-R不同版本之间的相关系数r = 0.88，在p小于0.001时具有显著性。与WAIS-R言语智商（VIQ）的相关系数，L版本为0.82，M版本为0.78；与操作智商（PIQ）的相关系数，L版本为0.46，M版本为0.38；与全量表智商（FSIQ）的相关系数，L版本为0.77，M版本为0.67。PPVT-R两个版本的所有相关系数均具有显著性。PPVT-R的平均得分确实显著低估了所有WAIS-R的平均得分。文中讨论了其意义。
