To examine the intelligibility and psychometric properties of the modified Dutch language version of the Work Limitations Questionnaire (WLQ) (WLQ-mdlv).
Employed patients with a physical chronic condition completed the WLQ-mdlv, the Work Ability Index, and the 36-item short form health survey. Intelligibility, internal consistency, test-retest reliability, and external construct validity of the WLQ-mdlv were assessed.
In 125 patients, the WLQ-mdlv showed improved intelligibility for a Dutch population. With Cronbach α coefficients more than .80, squared weighted κ of 0.63 or more (individual items), intraclass correlation coefficients of 0.83 or more (WLQ scales), a minimal detectable change of four points (WLQ index), and negative correlations with the Work Ability Index and related 36-item short form health survey scales reliability and external construct validity of the WLQ-mdlv were confirmed.
The WLQ-mdlv is an intelligible, reliable, and valid instrument for evaluating work limitations in employees with a chronic condition in the Netherlands.
考察改良后的荷兰语版工作限制问卷（WLQ）（WLQ-mdlv）的可理解性和心理测量学特性。
采用具有身体慢性疾病的患者完成了 WLQ-mdlv、工作能力指数和 36 项简短健康调查。评估了 WLQ-mdlv 的可理解性、内部一致性、重测信度和外部结构效度。
在 125 名患者中，WLQ-mdlv 显示出对荷兰人群更好的可理解性。Cronbach α 系数大于.80，平方加权 κ 大于 0.63（单项），内类相关系数大于 0.83（WLQ 量表），最小可检测变化为 4 分（WLQ 指数），与工作能力指数呈负相关，与相关 36 项简短健康调查量表具有可靠性和外部结构效度。
WLQ-mdlv 是一种可理解、可靠且有效的工具，可用于评估荷兰患有慢性疾病的员工的工作限制。
