ABSTRACT

This study investigated the validity and reliability of Turkish versions of the Waterloo Handedness and Footedness Questionnaire-Revised (WHQ-R and WFQ-R). Turkish versions of the WHQ-R and the WFQ-R, and other assessments (the Handedness Questionnaire and the Footedness Preference Test) were applied to 444 healthy participants aged between 18 and 65 years. The translation and cultural adaptation process of the WHQ-R and the WFQ-R was provided by the following proposed guideline. For test-retest reliability, translated versions were re-applied to 88 participants in a 7-day interval. Cronbach’s alpha of the WHQ-R was 0.984 and that of the WFQ was 0.905. The test-retest intra-class correlation coefficients (ICC) of the WHQ-R varied from 0.741 to 0.933 and those of the WFQ-R from 0.649 to 0.814. There were moderate to strong correlations between the WHQ-R and the Handedness Questionnaire (r = −853, p < 0.001) and between the WFQ-R and the Footedness Preference Test (r = −0.687, p < 0.001). Confirmatory factor analysis revealed a two-factor structure of the WHQ-R and the WFQ-R. The results of this study demonstrated that Turkish versions of the WHQ-R and the WFQ-R are reliable and valid inventories for assessing handedness and footedness in this population.

摘要

本研究调查了滑铁卢惯用手和足部问卷修订版（WHQ-R 和 WFQ-R）的土耳其语版本的有效性和可靠性。土耳其语版的 WHQ-R 和 WFQ-R 以及其他评估（惯用手调查问卷和足部偏好测试）适用于 444 名年龄在 18 至 65 岁之间的健康参与者。以下提议的指南提供了 WHQ-R 和 WFQ-R 的翻译和文化适应过程。为了测试再测试的可靠性，翻译版本在 7 天的时间间隔内重新应用于 88 名参与者。WHQ-R 的 Cronbach alpha 为 0.984，WFQ 的 Cronbach alpha 为 0.905。WHQ-R 的重测类内相关系数 (ICC) 从 0.741 到 0.933，WFQ-R 从 0.649 到 0.814。r  = -853, p  < 0.001) 以及在 WFQ-R 和足部偏好测试之间 ( r  = -0.687, p  < 0.001)。验证性因子分析揭示了 WHQ-R 和 WFQ-R 的双因子结构。这项研究的结果表明，土耳其语版本的 WHQ-R 和 WFQ-R 是评估该人群惯用手和足部习惯的可靠和有效清单。
