Problem behaviours are common among people with intellectual disabilities (ID), but psychometrically evaluated instruments for assessing such behaviours are scarce. The present study evaluated the psychometric properties of the Neuropsychiatric Inventory-Intellectual Disability (NPI-ID).
We assessed 108 residents with intellectual disabilities living in group-homes using the NPI-ID, which included the 12 symptoms of the original NPI-Nursing Home and two supplementary symptoms: self-injurious behaviour and impulsive risk-taking behaviour.
The NPI-ID showed adequate internal consistency (α = 0.76) and test-retest reliability (intraclass correlation coefficient = 0.88). Exploratory factor analysis revealed five factors accounting for 64.1% of the variance. Cluster analysis revealed that residents were clustered in three groups with distinctly different symptom profiles.
The psychometric properties were satisfactory, supporting the use of the NPI-ID as a screening tool for people with intellectual disabilities. Additional research is needed to further evaluate the utility of the NPI-ID among people with intellectual disabilities.
问题行为在智力残疾者中很常见，但用于评估此类行为的经过心理测量评估的工具却很稀缺。本研究评估了智力残疾神经精神病学量表（NPI-ID）的心理测量特性。
我们使用NPI-ID对108名居住在集体家庭中的智力残疾居民进行了评估，该量表包括原始NPI-疗养院的12种症状以及两种补充症状：自伤行为和冲动冒险行为。
NPI-ID显示出足够的内部一致性（α = 0.76）和重测信度（组内相关系数 = 0.88）。探索性因素分析揭示了五个因素，占方差的64.1%。聚类分析表明，居民被分为三组，症状特征明显不同。
心理测量特性令人满意，支持将NPI-ID用作智力残疾者的筛查工具。需要进一步研究以进一步评估NPI-ID在智力残疾者中的效用。
