Oswestry disability Index(ODI) is the commonest patient reported outcome for assessment of disability due to low back pain. Its application to non-English speaking Punjabi population is limited as a validated and cross culturally adapted Punjabi version of ODI is not available. The purpose of the study was to analyse the psychometric properties of Punjabi version of Oswestry disability index (ODI-P) in patients with mechanical low back pain.
The translation and cross-cultural adaptation of Punjabi version of ODI was done according to well recommended guidelines. The prefinal version was tested on a set of 15 patients and suitable modifications were made. The final version was administered to 113 patients with mechanical low back pain of more than two weeks duration. Psychometric properties comprising of internal consistency, test retest reliability, floor and ceiling effect, construct validity and factorial structure of the questionnaire were determined.
ODI-P showed excellent internal consistency (Chronbach alpha of ODI-P is 0.72), test retest reliability (ICC 0.891) and construct validity (Spearman correlation coefficient with VAS 0.424). Factor analysis proved the questionnaire to be having a 1-factor structure with a total variance of 48.61%.
ODI (P) is a reliable and valid instrument for measurement of disability related to mechanical low back pain in Punjabi population. It can be used both in research and clinical care settings in future.
奥斯威斯利残疾指数（ODI）是评估因腰痛导致残疾的最常用的患者报告结局指标。由于尚未有经过验证且跨文化改编的旁遮普语版ODI，其在不讲英语的旁遮普人群中的应用受到限制。本研究的目的是分析旁遮普语版奥斯威斯利残疾指数（ODI-P）在机械性腰痛患者中的心理测量特性。
ODI旁遮普语版的翻译和跨文化改编按照广泛推荐的指南进行。预终版在15名患者中进行了测试，并进行了适当修改。最终版应用于113例病程超过两周的机械性腰痛患者。确定了包括内部一致性、重测信度、地板效应和天花板效应、结构效度以及问卷的因子结构等心理测量特性。
ODI-P显示出优异的内部一致性（ODI-P的克朗巴赫α系数为0.72）、重测信度（组内相关系数ICC为0.891）和结构效度（与视觉模拟量表VAS的斯皮尔曼相关系数为0.424）。因子分析证明该问卷具有单因素结构，总方差为48.61%。
ODI（P）是测量旁遮普人群中与机械性腰痛相关残疾的可靠且有效的工具。未来可用于研究和临床护理环境。
