People with severe and profound levels of intellectual disability (ID) are frequently examined as a single group in research. However, these two groups may be significantly different, particularly in the area of emotional and behavioural difficulties.
The Developmental Behaviour Checklist (DBC) was completed by parents and caregivers of 107 people with severe ID and 22 people with profound ID at four time periods across 12 years. Regression analyses were used to examine trends in sub-scale scores across time and groups.
Significant differences between the groups of people with severe and profound ID were found. People with profound ID had significantly lower scores across all sub-scales except Social Relating. This was usually related to fewer items being selected as present for people with profound ID, as opposed to the scores being attributable to lower item severity scores.
There are significant differences between groups of people with severe and profound ID in scores on the DBC, indicating differences in behavioural and emotional problems. Caution should be exercised by researchers treating these two disparate groups as a single group, and by practitioners translating such findings into practice.
在研究中，严重和极重度智力障碍（ID）患者通常被作为一个单一群体进行检查。然而，这两个群体可能存在显著差异，特别是在情绪和行为困难方面。
在 12 年的 4 个时间段内，对 107 名严重 ID 患者和 22 名极重度 ID 患者的家长和照顾者进行了发育行为检查表（DBC）的评估。回归分析用于检验随时间和群体变化的子量表得分趋势。
在严重和极重度 ID 患者群体之间发现了显著差异。极重度 ID 患者在所有子量表上的得分均显著低于严重 ID 患者，除社会关系外。这通常与极重度 ID 患者选择的项目较少有关，而不是因为项目严重程度得分较低。
在 DBC 得分上，严重和极重度 ID 患者群体之间存在显著差异，表明行为和情绪问题存在差异。研究人员在将这两个截然不同的群体视为一个单一群体进行处理时，以及从业人员将这些发现转化为实践时，应谨慎行事。
