BACKGROUND/AIM: The multidimensional evaluation of patients with chronic neck pain is important for planning the treatment program. The aim of this study was to investigate the validity and reliability of the Turkish version of the Neck Bournemouth Questionnaire (NBQ).
The internal construct validity of the NBQ was examined by the fit of the data to the Rasch measurement model. External validity of the NBQ was evaluated by testing for expected associations of Rasch transformed NBQ score with the corresponding variables through the process of convergent validity. The reliability of the NBQ in terms of both internal consistency and test-retest reliability was assessed by the person separation index (PSI) and differential item functioning (DIF) by time effect.
It was determined that the questionnaire has 2 factors. None of the items of Factor 1 (F1) and Factor 2 (F2) showed DIF. The reliability of F1 (Cronbach’s alpha = 0.89, PSI = 0.87) and F2 (Cronbach’s alpha = 0.77, PSI = 0.87) was good with Cronbach’s alpha and PSI. There was a good correlation between NBQ/F1 and the Neck Disability Index (NDI) (r = 0.673) and Neck Pain and Disability Scale (NPDS) (r = 0.709). Also, there was a correlation between NBQ/F2 and the Beck Depression Inventory (BDI) (r = 0.552) and Beck Anxiety Inventory (BAI) (r = 0.410).
The Turkish version of the Neck Bournemouth Questionnaire is valid and reliable.
背景/目的：对慢性颈痛患者进行多维评估对于治疗方案的规划很重要。本研究旨在探讨土耳其版颈部 Bournemouth 问卷（NBQ）的有效性和可靠性。
通过数据拟合 Rasch 测量模型来检验 NBQ 的内部结构效度。通过 Rasch 转换后的 NBQ 得分与相应变量的预期关联的收敛有效性检验来评估 NBQ 的外部有效性。通过个体分离指数（PSI）和时间效应的差异项目功能（DIF）评估 NBQ 的内部一致性和重测信度的可靠性。
确定问卷有 2 个因子。因子 1（F1）和因子 2（F2）的任何项目均未显示 DIF。F1（克朗巴赫α=0.89，PSI=0.87）和 F2（克朗巴赫α=0.77，PSI=0.87）的可靠性良好，克朗巴赫α和 PSI 值较高。NBQ/F1 与颈部残疾指数（NDI）（r=0.673）和颈部疼痛和残疾量表（NPDS）（r=0.709）之间存在良好的相关性。此外，NBQ/F2 与贝克抑郁量表（BDI）（r=0.552）和贝克焦虑量表（BAI）（r=0.410）之间存在相关性。
土耳其版颈部 Bournemouth 问卷具有有效性和可靠性。
