This study examined the neurocognitive profiles of early adulthood attention-deficit/hyperactivity disorder (ADHD) patients using the Korean version of the Wechsler Adult Intelligence Scale, 4th Edition (K-WAIS-IV) and Continuous Performance Test 3rd Edition (CPT-3) assessment results.
A total of 105 individuals underwent the K-WAIS-IV assessment, and 68 participants completed the CPT-3. We examined the differences between intelligence subindex scores using paired t-tests and applied Pearson's correlation analysis to determine the correlation between the K-WAIS-IV and CPT-3 scores.
Working Memory Index scores were significantly lower than Verbal Comprehension Index scores, whereas Processing Speed Index (PSI) scores were significantly lower than all three other subindex scores. Significant negative correlations were found between all four K-WAIS-IV subindex scores and the CPT-3 scores for Detectability, Omissions, Commissions, Perseverations, Hit Reaction Time, Hit Reaction Time Standard Deviation, and Variability.
The PSI of the K-WAIS-IV can be considered a useful predictor in early adulthood ADHD patients combined with the CPT-3 examination.
本研究使用韩国版韦氏成人智力量表第四版（K-WAIS-IV）和连续性能测试第三版（CPT-3）的评估结果，对成年早期注意力缺陷多动障碍（ADHD）患者的神经认知特征进行了研究。
共有105人接受了K-WAIS-IV评估，68名参与者完成了CPT-3。我们使用配对t检验检查了智力子指数得分之间的差异，并应用Pearson相关分析来确定K-WAIS-IV和CPT-3得分之间的相关性。
工作记忆指数得分显著低于言语理解指数得分，而加工速度指数（PSI）得分显著低于其他三个子指数得分。在K-WAIS-IV的所有四个子指数得分与CPT-3的可检测性、遗漏、 commission、持续性、命中反应时间、命中反应时间标准差和变异性得分之间发现了显著的负相关。
结合CPT-3检查，K-WAIS-IV的PSI可被认为是成年早期ADHD患者的有用预测指标。
