There is paucity in availability of valid and reliable measures of psychopathology that can be routinely applied with an intellectual disability (ID) population in clinical practice. The psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item version (CORE-LD30) are examined.
The CORE-LD30 was administered to 271 sequential referrals to three National Health Service (NHS) ID services providing psychological support. A principal components analysis with oblique rotation was conducted with examination of convergent validity for extracted domains.
Three rotated factors were extracted with good levels of internal consistency reported for the overall measure (α = 0.92) and each of the domains, conceptually labelled Problems/Symptoms (α = 0.90), Risk to Self (α = 0.76) and Risk to Others (α = 0.71). Convergent validity is reported for two domains [Problems/Symptoms with the Glasgow Depression Scale for people with a learning disability (LD) and Risk to Others with the Health of the Nation Outcome Scale-LD], and support for the CORE-LD30 as a 'core' measure indicated.
The CORE-LD30 is recommended as a useful broad ranging measure of psychopathology for use with an ID population. Domains may prove to be useful for research and clinical purposes. Further research is recommended to examine the ability to monitor clinical change associated with specific levels of presentation and different clinical presentations/cohorts.
在临床实践中，针对智力障碍（ID）人群，能够常规应用的有效且可靠的精神病理学测量工具十分匮乏。本文旨在研究临床结局常规评估-学习障碍 30 项版本（CORE-LD30）的心理测量学特性。
CORE-LD30 被用于评估三个英国国家医疗服务体系（NHS）ID 服务机构的 271 名连续转介者，这些机构为患者提供心理支持。采用斜交旋转的主成分分析法，对提取的领域进行收敛效度检验。
提取出三个旋转因子，整体测量的内部一致性水平较高（α=0.92），每个领域的内部一致性水平也较高，分别为问题/症状领域（α=0.90）、自我风险领域（α=0.76）和他人风险领域（α=0.71）。两个领域的收敛效度得到了报告[问题/症状与学习障碍人群的格拉斯哥抑郁量表（GDS-LD），以及他人风险与健康国家结局量表-学习障碍（HoNOS-LD）]，并支持 CORE-LD30 作为“核心”测量工具。
CORE-LD30 被推荐作为一种针对 ID 人群使用的、具有广泛应用范围的精神病理学测量工具。这些领域可能对研究和临床目的有用。建议进一步研究以检验与特定表现水平和不同临床表现/队列相关的临床变化监测能力。
