To validate a Spanish version of the Northwick Park Neck Pain Questionnaire (NPQ) and to prove its usefulness in clinical practice.
We studied 58 patients with non-inflammatory neck pain of more than 4 months duration. A blind back translation of the NPQ was made, and the resulting back-translation version was then compared with the original. The NPQ comprises 9 questions with 5 statements of increasing difficulty. Patients completed the questionnaire 3 times: on their initial assessment; 8-10 days later (test-retest); and after physiotherapy treatment 3 months later. Neck pain was assessed by a visual analogue scale (VAS).
Fifty-three patients completed the questionnaire (90%). There was a good intra-class correlation between the test-retest NPQ (r = 0.63), indicating good agreement. For each of the 9 sections, agreement ranged from r = 0.43 to r = 0.85, p < 0.05 in all cases. Correlation with the VAS was also good, between r = 0.51 (test) and r = 0.74 (retest) (p < 0.05 in all cases). Pain measured by the VAS increased according to the NPQ score, grouped by percentages (p = 0.003). The mean scores for each section increased with that of the intensity of pain, in most sections showing good internal consistency. Pain and the NPQ score improved after treatment (56.1 +/- 20.2 to 29.9 +/- 20.1, p = 0.0001 and 45.9% +/- 12.7% to 28.9% +/- 15.3%, p = 0.0001 respectively), as did all the other items except for driving (p < 0.05).
The Spanish version of the NPQ is a feasible, reliable and valid instrument to measure pain in Spanish-speaking patients with chronic neck pain.
验证西班牙文版的诺斯威克公园颈部疼痛问卷（NPQ），并证明其在临床实践中的实用性。
我们研究了58例持续时间超过4个月的非炎性颈部疼痛患者。对NPQ进行了盲法回译，然后将得到的回译版本与原文进行比较。NPQ包括9个问题及5个难度递增的陈述。患者完成问卷3次：初次评估时；8 - 10天后（重测）；3个月后物理治疗后。通过视觉模拟量表（VAS）评估颈部疼痛。
53例患者完成了问卷（90%）。重测NPQ之间存在良好的组内相关性（r = 0.63），表明一致性良好。对于9个部分中的每一个，一致性范围从r = 0.43到r = 0.85，所有情况下p < 0.05。与VAS的相关性也良好，测试时r = 0.51，重测时r = 0.74（所有情况下p < 0.05）。根据NPQ评分分组，VAS测量的疼痛按百分比增加（p = 0.003）。每个部分的平均得分随疼痛强度得分增加，大多数部分显示出良好的内部一致性。治疗后疼痛和NPQ评分有所改善（分别从56.1±20.2降至29.9±20.1，p = 0.0001；从45.9%±12.7%降至28.9%±15.3%，p = 0.0001），除驾驶外的所有其他项目也有所改善（p < 0.05）。
西班牙文版的NPQ是一种可行、可靠且有效的工具，可用于测量讲西班牙语的慢性颈部疼痛患者的疼痛情况。
