The study evaluated the convergent validity of the PEAK-E-PA and two common assessments of language development used in educational and clinical settings: the ABLLS-R and the TOLD-I:4. The PEAK-E-PA provides a measure of a participant’s ability to derive arbitrary stimulus relations, and may therefore provide a more complex analysis of language functioning than traditional behavior analytic language assessments. The results of the present study support a strong, significant relationship between the PEAK-E-PA and the ABLLS-R (r = 0.73, p < 0.01), but the obtained coefficient falls within the lower range of prior psychometric evaluations of behavioral language assessments. The results suggest a stronger relationship between the PEAK-E-PA the TOLD-I:4 (r = 0.94, p < 0.01), supporting the use of the PEAK-E-PA with individuals with autism who have progressed beyond the elementary verbal operant skills assessed for in traditional behavioral assessments.

这项研究评估了PEAK-E-PA的收敛效度，以及在教育和临床环境中使用的两种常见的语言发展评估：ABLLS-R和TOLD-I：4。PEAK-E-PA提供了一种衡量参与者获得任意刺激关系的能力的指标，因此可以提供比传统行为分析语言评估更复杂的语言功能分析。本研究的结果支持PEAK-E-PA与ABLLS-R之间的密切关系（r  = 0.73，p  <0.01），但获得的系数落在先前对行为语言进行心理测评的较低范围内评估。结果表明PEAK-E-PA与TOLD-I：4（r = 0.94，p  <0.01），支持自闭症患者的PEAK-E-PA的使用已超出传统行为评估所评估的基本言语操作技能。
