PPPD is a chronic and functional disorder without diagnostic data and definitive laboratory tests. In such conditions, questionnaires are the easiest quantifiable measures to identify and rate the severity of individuals suffering from PPPD. The current study aimed to adapt the Niigata PPPD Questionnaire (NPQ) into Tamil language and analyze its psychometric properties. A conventional method of translation involving forward and backward translation was carried out, followed by subsequent content validation. The translated version was field tested in three groups, the controls, the dizzy group, and PPPD group, for further analysis. The final Tamil version of the questionnaire, NPQ-T, had good reliability and validity. This version was identified to have good sensitivity and specificity in discriminating the PPPD group from the dizzy group. The NPQ in Tamil (NPQ-T) is a valid tool for identifying individuals with PPPD and noting the severity of the exacerbating factors.
持续性姿势-知觉性头晕（PPPD）是一种慢性功能性疾病，没有诊断数据和确定性的实验室检查。在这种情况下，问卷是识别和评估PPPD患者严重程度的最容易量化的方法。本研究旨在将新潟PPPD问卷（NPQ）翻译成泰米尔语，并分析其心理测量特性。采用了包括正向和反向翻译的传统翻译方法，随后进行内容验证。翻译后的版本在三组中进行了现场测试，即对照组、头晕组和PPPD组，以进行进一步分析。问卷的最终泰米尔语版本NPQ-T具有良好的信度和效度。该版本在区分PPPD组和头晕组方面具有良好的敏感性和特异性。泰米尔语版的NPQ（NPQ-T）是识别PPPD患者并记录加重因素严重程度的有效工具。
