This study aimed to validate the Farsi version of Neuropsychiatric Inventory (F-NPI), with the aim of promoting clinical assessment and local research on evaluation of neuropsychiatric symptom profiles of individuals with dementia in Iran.
In this cross-sectional, psychometric study, 100 patients with dementia in the age range of 60–90 years participated. Two trained psychiatrists interviewed the study subjects. Positive and Negative Symptoms Scale (PANSS) and Geriatric Depression Scale (GDS) were used to determine the concurrent validity. Testretest,inter-rater reliability and internal consistency were calculated. Discrimination validity was determined,using a matched control group consisting of 49 participants without dementia. Cronbach’s α and Pearson’ scorrelation coefficients were used to analyze the data.
The internal consistency (Cronbach’s α = 0.9) was excellent. The inter-rater reliability varied between 0.6 and 0.98 for frequency, severity and total scale of the F-NPI, and test-retest reliability was between 0.4 and 0.96. Concurrent validity varied between 0.3 and 0.9 (P < 0.05). The most prevalent symptom was “apathy” and the least prevalent was “euphoria”.
The Farsi version of NPI has satisfactory psychometric indexes and is applicable for clinical and study works in Iranian community.
本研究旨在验证神经精神问卷的波斯语版本（F-NPI），旨在促进伊朗对痴呆患者神经精神症状谱的临床评估和当地研究。
在这项横断面、心理测量学研究中，100 名年龄在 60-90 岁之间的痴呆患者参与了研究。两名经过培训的精神科医生对研究对象进行了访谈。阳性和阴性症状量表（PANSS）和老年抑郁量表（GDS）用于确定同时效度。计算了测试-重测、组内一致性和内部一致性。使用由 49 名无痴呆症参与者组成的匹配对照组来确定鉴别效度。使用 Cronbach 的 α 和 Pearson 相关系数分析数据。
内部一致性（Cronbach 的 α = 0.9）非常好。F-NPI 的频率、严重程度和总分的组内一致性在 0.6 到 0.98 之间，测试-重测的可靠性在 0.4 到 0.96 之间。同时效度在 0.3 到 0.9 之间（P < 0.05）。最常见的症状是“冷漠”，最不常见的是“欣快”。
NPI 的波斯语版本具有令人满意的心理测量学指标，适用于伊朗社区的临床和研究工作。
