Sensitivity theory proposes that there are wide individual differences in what motivates people with intellectual disability. The Reiss Profile MR/DD is a rating scale that measures 15 fundamental motives. This study examined the internal consistency and interrater reliability of the 15 subscales as well as the validity of motivational profiles.
The study consisted of two distinct but related steps. First, the interrater reliability of the rating scale was established by having pairs of raters evaluate 48 individuals. Second, raters were presented with three different motivational profiles and asked to identify which one corresponded to the individual they had rated 4 weeks earlier.
Results indicated good internal consistency (average alpha=0.84), significant variability in the interrater reliability (average intraclass correlation coefficient=0.52), and excellent validity (95% of the correct profiles were chosen). Average discrepancies between pairs of raters are presented.
Interrater reliability is an important topic for professionals working in the field of intellectual disability and results are discussed in terms of the factors that affect it. This is the first published study to report on the interrater reliability of the Reiss Profile MR/DD.
敏感性理论提出，智力残疾者的动机存在广泛的个体差异。赖斯智残量表是一种测量15种基本动机的评定量表。本研究考察了15个分量表的内部一致性和评分者间信度，以及动机剖面图的效度。
该研究包括两个不同但相关的步骤。首先，通过让评分者对48名个体进行评估来确定评定量表的评分者间信度。其次，向评分者展示三种不同的动机剖面图，并要求他们识别哪一种与他们四周前评定的个体相对应。
结果表明内部一致性良好（平均阿尔法系数=0.84），评分者间信度存在显著差异（平均组内相关系数=0.52），效度极佳（95%的正确剖面图被选中）。呈现了评分者对之间的平均差异。
评分者间信度是智力残疾领域专业人员的一个重要课题，并根据影响它的因素对结果进行了讨论。这是首次发表的关于赖斯智残量表评分者间信度的研究。
