BACKGROUND
Neck pain is a common problem that can greatly affect a person's activities of daily living. Functional status questionnaires are important in assessing this effect, and are used to follow up neck pain management programs. The Neck Disability Index (NDI) is the first-created scale for neck pain-related disability and is widely translated and in common used in many countries. Our aim is investigate to clinometric properties of a Turkish version of modified NDI and to give a choice in daily practise of versions to be used.
METHODS
The modified NDI was applied to 30 patients for reliability. 185 patients participated in the validity study. All patients were recruited from the outpatient clinic of our department. The scale was translated by the forward and backward translation procedure according to the COSMIN criteria. The test was repeated at 48 hours interval for reliability study. SPSS-10.0, software was used for statistical analyses. The Intraclass correlation coefficient was used for the test- retest reliability of the modified NDI. Cronbach α was used for internal consistency. Factor analysis was used for construct validity. The validity of the modified NDI with respect to the SF-36, HAD, VAS pain, VAS disability was assessed using Spearman correlations.
RESULTS
The Intraclass correlation coefficient between first and second (within 48 hours) evaluation of test (rs) was 0.92. Questions 1,4,6,8,10 were shown to have excellent reliability. (rs > 0.9). Question 10 was the most frequently challenged question because "recreational and social activities" do not have not the same meanings in Turkey than in western countries. This required that detailed explanations be provided by the investigators. Cronbach's alpha for the total index was 0.88. A single factor accounting for 80.2% of the variance was obtained. Validity studies demonstrated good and moderate correlations (rs) among NDI, HAD, VAS, physical function subtitle of SF 36 (0.62, 0.76, 0.68).
CONCLUSIONS
The modified NDI-Turkish version is a reliable and valid test and is suitable for daily practise.
背景
颈部疼痛是一种常见的问题，会极大地影响一个人的日常生活活动。功能状态问卷在评估这种影响方面非常重要，并且用于随访颈部疼痛管理计划。颈部残疾指数（NDI）是第一个针对颈部疼痛相关残疾的量表，已被广泛翻译并在许多国家使用。我们的目的是研究改良 NDI 的土耳其语版本的临床计量学特性，并在日常实践中提供可供选择的版本。
方法
对 30 名患者进行可靠性测试。185 名患者参加了有效性研究。所有患者均从我们科室的门诊招募。根据 COSMIN 标准，通过正向和反向翻译程序翻译量表。为了进行可靠性研究，测试在 48 小时的间隔内重复进行。使用 SPSS-10.0 软件进行统计分析。使用组内相关系数评估改良 NDI 的测试-再测试可靠性。Cronbach α 用于内部一致性。因子分析用于结构有效性。改良 NDI 与 SF-36、HAD、VAS 疼痛、VAS 残疾的相关性使用 Spearman 相关评估。
结果
第一次和第二次（在 48 小时内）评估之间的组内相关系数（rs）为 0.92。问题 1、4、6、8、10 的可靠性非常好（rs>0.9）。问题 10 是最具挑战性的问题，因为“娱乐和社交活动”在土耳其与西方国家的含义不同。这要求调查人员提供详细的解释。总指数的 Cronbach α 为 0.88。获得了一个占方差 80.2%的单一因素。有效性研究表明，NDI、HAD、VAS、SF-36 的物理功能子标题之间存在良好和中度相关性（rs）（0.62、0.76、0.68）。
结论
改良 NDI-土耳其语版本是一种可靠有效的测试，适用于日常实践。
