Amyotroph Lateral Scler Other Motor Neuron Disord. 2001 Dec;2(4):197-201. doi: 10.1080/14660820152882205.
The purpose of this study was to compare the performance of the five-item mental health dimension of SF-36 (the Mental Health Index, MHI-5) with that of the 22-item Psychological General Well-Being Index (PGWB) in patients presenting with amyotrophic lateral sclerosis/motor neuron disease, using tests of reliability and validity.
A questionnaire-based survey of patients diagnosed with ALS across 15 European countries.
Patients presenting at neurological clinics for treatment of their ALS were asked to join the survey.
1048 patients with ALS have been recruited, of whom 861 (82.2%) have returned baseline questionnaires. There was evidence supporting the internal consistency of both instruments, and for their construct validity in distinguishing between groups, in terms of gender and age. The scores on the two instruments were highly correlated (Spearman rank correlation 0.85).
Both the MHI-5 and the PGWB showed high levels of construct validity and internal reliability in this patient group. The MHI-5 has comparable psychometric performance to the PGWB, and can be used to measure and compare mental health in defined populations.
本研究旨在通过信效度检验，比较肌萎缩侧索硬化症/运动神经元病患者中，简短健康调查问卷（SF - 36）中五项心理健康维度（心理健康指数，MHI - 5）与22项心理总体幸福感指数（PGWB）的表现。
对15个欧洲国家诊断为肌萎缩侧索硬化症的患者进行基于问卷的调查。
在神经科诊所就诊接受肌萎缩侧索硬化症治疗的患者被邀请参加调查。
招募了1048例肌萎缩侧索硬化症患者，其中861例（82.2%）返回了基线调查问卷。有证据支持两种工具的内部一致性，以及它们在按性别和年龄区分组方面的结构效度。两种工具的得分高度相关（斯皮尔曼等级相关系数为0.85）。
在该患者群体中，MHI - 5和PGWB均显示出较高水平的结构效度和内部信度。MHI - 5在心理测量性能上与PGWB相当，可用于测量和比较特定人群的心理健康状况。
