To evaluate the psychometric properties of the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) in paediatric neurodevelopment clinics.
Participants were 181 children (aged 6-18y) attending paediatric services in Scotland, divided into three age groups according to previous CAIDS-Q standardization cut-off scores. Fifty-four children (37 males, 17 females; mean age 117mo [SD 29.9mo]) met the criteria for intellectual disability and 127 did not (88 males, 39 females; mean age 120.1mo [SD 32.7mo]). A number of psychometric properties of the CAIDS-Q were evaluated, including test-retest and interrater reliability, convergent validity, sensitivity, specificity, and positive and negative predictive values based on existing cut-off scores.
Significant positive relationships were found for all three age groups between CAIDS-Q scores and measures of intellectual and adaptive functioning. Test-retest reliability ranged from 'moderate' to 'almost perfect', whereas interrater reliability ranged from 'fair' to 'almost perfect'. Sensitivity and positive predictive value were 100% for all groups and specificity was between 83% and 94%, depending on age. Negative predictive values ranged from 75% to 91%.
The CAIDS-Q appears to show psychometric properties that support its use as a screen for intellectual disability in paediatric neurodevelopmental settings.
The Child and Adolescent Intellectual Disability Screening Questionnaire showed good psychometric properties. It identified all participating children who met the criteria for intellectual disability. Between 83% and 94% of children without intellectual disability were also correctly identified.
评估儿童青少年智力障碍筛查问卷（CAIDS-Q）在儿科神经发育门诊的心理测量特性。
参与者为 181 名在苏格兰儿科就诊的儿童（6-18 岁），根据之前 CAIDS-Q 标准化截断分数分为三组。54 名儿童（37 名男性，17 名女性；平均年龄 117 个月[SD 29.9 个月]）符合智力障碍标准，127 名儿童不符合（88 名男性，39 名女性；平均年龄 120.1 个月[SD 32.7 个月]）。评估了 CAIDS-Q 的一些心理测量特性，包括重测信度和评分者间信度、聚合效度、敏感性、特异性以及基于现有截断分数的阳性和阴性预测值。
所有三组的 CAIDS-Q 评分与智力和适应功能的测量值均呈显著正相关。重测信度范围为“中度”至“几乎完美”，而评分者间信度范围为“公平”至“几乎完美”。所有组的敏感性和阳性预测值均为 100%，特异性取决于年龄，在 83%至 94%之间。阴性预测值范围为 75%至 91%。
CAIDS-Q 似乎具有支持其在儿科神经发育环境中作为智力障碍筛查工具的心理测量特性。
儿童青少年智力障碍筛查问卷具有良好的心理测量特性。它识别出所有符合智力障碍标准的参与儿童。83%至 94%的无智力障碍儿童也得到了正确识别。
