: The Walking Impairment Questionnaire (WIQ) is a short and simple tool to measure walking impairment for patients with peripheral arterial disease requiring no special equipment or trained staff. The aim of this study was to assess the validity and reliability of the culturally adapted Lithuanian WIQ version in patients with intermittent claudication. : In total, 40 patients with intermittent claudication and ankle-brachial index < 0.90 participated in this study. Reliability and internal consistency of the questionnaire were assessed by the intra-class correlation coefficient (ICC) and Cronbach's alpha (α), respectively. Validity was determined by correlations between the WIQ scores and a subjective test (Quality of Life 5 Dimension Questionnaire 3 Level Version (EQ-5D-3L)) and objective tests (6 min walk test (6MWT), treadmill test, and ankle-brachial index). : The test-retest reliability was assessed as excellent with an intraclass correlation coefficient of 0.90. The values of Cronbach's alpha were 0.957 (I time) and 0.948 (II time) and indicated an excellent internal consistency. Statistically significant Spearman correlations were detected between the WIQ and walking distances on the 6MWT (rho 0.514, < 0.001) and treadmill test (rho 0.515, < 0.001). Higher WIQ scores were associated with longer walking distances and duration. Moderate negative and low negative correlations were found between the WIQ and EQ-5D-3L scores. : The Lithuanian version of culturally adapted WIQ demonstrates reliability and validity for patients with intermittent claudication, supported by two different walking tests showing statistically significant moderate Spearman correlations.
: 行走障碍问卷（WIQ）是一种简短而简单的工具，用于测量需要特殊设备或训练有素的工作人员的外周动脉疾病患者的行走障碍。本研究的目的是评估文化适应的立陶宛语 WIQ 版本在间歇性跛行患者中的有效性和可靠性。: 共有 40 名间歇性跛行且踝肱指数<0.90 的患者参与了这项研究。通过组内相关系数（ICC）和 Cronbach's alpha（α）分别评估问卷的可靠性和内部一致性。通过 WIQ 评分与主观测试（生活质量 5 维 3 级问卷（EQ-5D-3L））和客观测试（6 分钟步行测试（6MWT）、跑步机测试和踝肱指数）之间的相关性来确定有效性。: 测试-重测可靠性评估为优秀，组内相关系数为 0.90。Cronbach's alpha 的值为 0.957（第一次）和 0.948（第二次），表明内部一致性极好。在 WIQ 与 6MWT（rho 0.514，<0.001）和跑步机测试（rho 0.515，<0.001）上的步行距离之间检测到统计学上显著的 Spearman 相关性。WIQ 得分越高，行走距离和持续时间越长。WIQ 与 EQ-5D-3L 评分之间存在中度负相关和低度负相关。: 文化适应的立陶宛语 WIQ 版本对间歇性跛行患者具有可靠性和有效性，两种不同的步行测试均支持具有统计学意义的中度 Spearman 相关性。
