儿童脑肿瘤幸存者患神经认知障碍的风险增加，包括工作记忆（WM）问题。WM通常使用性能指标进行评估。鲜为人知的是，父母的评级确定WM的困难，评分员和性能指标之间的关系，或预测父母报告WM的问题，在这个人口的价值。因此，目前的研究探讨了父母报告的效用，在检测WM困难的儿童脑肿瘤幸存者接受适形放射治疗（n=50）相对于兄弟姐妹（n=40）和实体瘤幸存者没有接受CNS定向治疗（n=40）。父母完成了执行功能的行为评定量表（BRIEF）。参与者被管理WM措施（数字广度，自我排序的搜索任务）。结果显示，与对照组相比，父母认为脑肿瘤幸存者有更多的WM问题（p<0.01）。然而，BRIEF-WM量表在检测基于性能的问题时表现出较差的灵敏度和特异性。在合并组中，BRIEF-WM量表与绩效指标之间存在显著相关性（r=-0.24-0.22; p<0.05）。测试时的年龄、社会经济状况和智商是父母报告的WM问题的重要预测因素。评估者和绩效指标在评估WM时提供了互补但不同的信息，这重申了在临床评估中利用两者的重要性。
Childhood brain tumor survivors are at increased risk for neurocognitive impairments, including working memory (WM) problems. WM is typically assessed using performance measures. Little is known about the value of parent ratings for identifying WM difficulties, the relationship between rater and performance measures, or predictors of parent-reported WM problems in this population. Accordingly, the current study examined the utility of parent report in detecting WM difficulties among childhood brain tumor survivors treated with conformal radiation therapy (n=50) relative to siblings (n=40) and solid tumor survivors not receiving CNS-directed therapy (n=40). Parents completed the Behavior Rating Inventory of Executive Function (BRIEF). Participants were administered WM measures (digit span, self-ordered search tasks). Findings revealed parents rated brain tumor survivors as having significantly more WM problems (p<.01) compared to controls. However, the BRIEF-WM scale demonstrated poor sensitivity and specificity for detecting performance-based problems. Significant, albeit modest, correlations were found between the BRIEF-WM scale and performance measures (r=−.24 −.22; p<.05) for the combined group. Age at testing, socioeconomic status, and IQ were significant predictors of parent reported WM problems. Rater and performance measures offer complimentary yet different information in assessing WM, which reiterates the importance of utilizing both within the context of clinical assessment.
