摘要

我们研究了 WAIS-IV GAI 的显著分散是否会降低其预测 WMS-IV 指标表现的有效性。研究对象包括 330 名患有神经、精神或神经发育障碍的患者,以及 59 名无可诊断障碍的转介患者。对于 VCI > PRI,59.32% 在 p 22 点时具有显著性。对于 VCI p 22 点。GAI 各分测验间的散点显示,82.26%的人有显著的散点范围,13.88%的人有异常大的范围(≥8)。在 VCI 中,49.10% 的人有显著的散点(≥3),12.08% 的人有异常大的散点范围(≥5)。在 PRI 方面,43.19% 有明显的分散范围(≥4),12.85% 有异常大的分散范围(≥6)。调节分析显示,GAI 是 WMS-IV 各项指数的重要预测因子。对于任何指数,GAI 与 GAI 散度的交互项都不显著,这表明根据 GAI 预测 WMS-IV 分数的回归方程在不同的散度水平上没有显著差异。即使在 VCI-PRI 存在显著差异且 GAI 各分测验之间存在异常变异的情况下,根据 GAI 估算 WMS-IV 指数也是合理的。

Does high scatter on the Wechsler Adult Intelligence Scale-Fourth Edition general ability index reduce validity in predicting Wechsler Memory Scale-Fourth Edition indexes?

We examined whether significant scatter in WAIS-IV GAI will reduce its validity to predict performance on WMS-IV indexes. Participants were 330 individuals with neurological, psychiatric, or neurodevelopmental disorders and 59 referrals who were found to be free of a diagnosable disorder. For VCI > PRI, 59.32% were significant at p < .05 and 12.29% were >22 points. For VCI < PRI, 48.37% were significant at p < .05 and 7.19% were >22 points. Inter-subtest scatter across GAI subtests indicated 82.26% of individuals had a significant scatter range and 13.88% had an unusually large range (≥8). For the VCI, 49.10% had significant scatter (≥3) and 12.08% had an unusually large scatter range (≥5). On the PRI, 43.19% had a significant scatter range (≥4) and 12.85% had an unusually large degree of scatter (≥6). Moderation analyses revealed GAI was a significant predictor of each WMS-IV index. The interaction term of GAI with GAI scatter was not significant for any indexes, indicating that regression equations for predicting WMS-IV scores from GAI did not vary significantly across levels of scatter. Estimation of WMS-IV indexes from the GAI is justified even when significant VCI-PRI discrepancies are present and there is unusual variability across the GAI subtests.
