对于智力残疾和自闭症双重残疾儿童智力/发育水平的量化标准，目前还没有达成一致意见。因此，我们研究了心理教育概貌修订版(PEP-R)的心理测量学特性及其在这一人群中的应用。我们从一家专门的自闭症诊所的日托和住院数据库中识别出116名患有双重残疾的儿童。收集并分析PEP-R的量表和领域水平得分。我们在不同年龄、不同功能水平和不同自闭症严重程度的双重残疾儿童中，检验了PEP-R的内部一致性、PEP-R的领域总相关和PEP-R与Gesell的发展计划、评定者间和重测信度和效度的并发效度。PEP-R除了具有良好的表面效度和内容效度外，还表现出良好的内部一致性(Cronbach‘s a在0.91-0.93之间)和领域-总体相关(在0.75-0.90之间)。PEP-R评分员间信度(组内相关系数，ICC=0.96)和重测信度(ICC=0.87)良好。GDS具有中到高的同时效度(r范围为0.61~0.82；P均=0.001)。在婴幼儿、幼儿、学龄前儿童和小学生中，PEP-R作为一种发育测量工具的实用性较好。无论自闭症的严重程度如何，PEP-R测量发育年龄的能力都很好，但在高功能儿童中表现更好。PEP-R作为智力/发育测验，在双重残疾儿童中具有很强的心理测量学特性。它可以用于不同年龄段和自闭症严重程度的儿童。对于功能低下的双重残疾儿童，应谨慎使用PEP-R作为发育测试。
There is no agreement about the measure to quantify the intellectual/ developmental level in children with the dual disability of intellectual disability and autism. Therefore, we studied the psychometric properties and utility of Psycho-Educational Profile-Revised (PEP-R) as a developmental test in this population. We identified 116 children with dual disability from the day care and inpatient database of a specialised Autism Clinic. Scale and domain level scores of PEP-R were collected and analyzed. We examined the internal consistency, domain-total correlation of PEP-R and concurrent validity of PEP-R against Gesell's Developmental Schedule, inter-rater and test-retest reliability and utility of PEP-R among children with dual disability in different ages, functional level and severity of autism. Besides the adequate face and content validity, PEP-R demonstrates a good internal consistency (Cronbach's a ranging from 0.91 to 0.93) and domain-total correlation (ranging from 0.75 to 0.90). The inter-rater reliability (intraclass correlation coefficient, ICC = 0.96) and test-retest reliability (ICC = 0.87) for PEP-R is good. There is moderate-to-high concurrent validity with GDS (r ranging from 0.61 to 0.82; all Ps = 0.001). The utility of PEP-R as a developmental measure was good with infants, toddlers, pre-school and primary school children. The ability of PEP-R to measure the developmental age was good, irrespective of the severity of autism but was better with highfunctioning children. The PEP-R as an intellectual/ developmental test has strong psychometric properties in children with dual disability. It could be used in children with different age groups and severity of autism. PEP-R should be used with caution as a developmental test in children with dual disability who are low functioning.
