A cross-sectional study.
To evaluate cross-cultural adaptation and psychometric properties of the Copenhagen Neck Function Disability Scale (CNFDS) and Neck Bournemouth Questionnaire (NBQ) in patients with chronic nonspecific neck pain.
CNFDS and NBQ are among the most popular scales to investigate aspects of life in patients with chronic neck pain. To date, the Persian versions of these scales have not been validated.
Following the translation process, the questionnaires were given to 106 patients with chronic nonspecific neck pain. To evaluate reliability, Cronbach alpha and test-retest reliability were evaluated. To investigate construct validity, the Neck Disability Index (NDI) and Neck Pain Disability Scale (NPDS) were used. Internal consistency of the scales was evaluated with exploratory factor analysis.
No missing data were observed for the NBQ, and missing data affected 0% to 3% of the CNFDS items. There were no floor or ceiling effects. Cronbach alpha was 0.92 for the CNFDS and 0.95 for the NBQ. Test-retest reliability was estimated as 0.86 for the CNFDS and 0.91 for the NBQ. The CNFDS correlated very well with the NDI pain subscale, and the NPDS. The NBQ correlated very well with the NPDS and NDI, and correlated well with the CNFDS and its subscales. Exploratory factor analysis detected three dimensions for the CNFDS and confirmed unidimensionality of the NBQ.
The Persian versions of the CNFDS and NBQ have acceptable validity and reliability for use with Persian-speaking patients with chronic nonspecific neck pain.
横断面研究。
评估慢性非特异性颈痛患者使用哥本哈根颈部功能障碍量表（CNFDS）和颈部 Bournemouth 问卷（NBQ）的跨文化适应性和心理测量特性。
CNFDS 和 NBQ 是用于研究慢性颈痛患者生活方面的最受欢迎的量表之一。迄今为止，这些量表的波斯语版本尚未经过验证。
经过翻译过程，问卷被分发给 106 名患有慢性非特异性颈痛的患者。为了评估可靠性，评估了 Cronbach α 和重测信度。为了研究结构有效性，使用了颈部残疾指数（NDI）和颈部疼痛残疾量表（NPDS）。使用探索性因子分析评估了量表的内部一致性。
NBQ 没有缺失数据，而 CNFDS 受影响的项目占 0%至 3%。没有地板或天花板效应。CNFDS 的 Cronbach α 为 0.92，NBQ 为 0.95。CNFDS 的重测信度估计为 0.86，NBQ 为 0.91。CNFDS 与 NDI 疼痛子量表和 NPDS 非常相关。NBQ 与 NPDS 和 NDI 非常相关，与 CNFDS 及其子量表也有很好的相关性。探索性因子分析检测到 CNFDS 的三个维度，并证实了 NBQ 的单维度性。
CNFDS 和 NBQ 的波斯语版本在使用波斯语的慢性非特异性颈痛患者中具有可接受的有效性和可靠性。
