No vitiligo-specific quality of life scale exists.
To develop a reliable and valid quality of life scale for vitiligo patients.
The content was derived from in-depth interviews with vitiligo patients. The internal consistency, test-retest reliability and validity of the scale, VLQI (Vitiligo Life Quality Index), were evaluated.
Internal consistency was high with 30 patients and then with 183 patients (Cronbach's α 0.92 and 0.91). Test-retest scores were correlated (r = 0.86, p < 0.001). There was no difference between the test and retest scores (p > 0.05). VLQI was correlated with DLQI (Dermatology Life Quality Index) (r = 0.77, p < 0.001) and with the perceived severity by the patients (r = 0.57, p < 0.001). There was a significant relationship between the VLQI and the extent of the disease (p = 0.015). Factor analysis revealed six subscales.
The VLQI is a valid and reliable instrument assessing quality of life of vitiligo patients.
目前尚无专门针对白癜风的生活质量量表。
研制一种可靠、有效的白癜风患者生活质量量表。
该量表的内容源于对白癜风患者的深入访谈。对该量表（VLQI，白癜风生活质量指数）的内部一致性、重测信度和效度进行了评估。
对 30 名患者和 183 名患者进行内部一致性检验，Cronbach's α 值分别为 0.92 和 0.91。重测评分相关（r = 0.86，p < 0.001）。测试和重测评分之间无差异（p > 0.05）。VLQI 与 DLQI（皮肤病生活质量指数）（r = 0.77，p < 0.001）和患者感知严重程度（r = 0.57，p < 0.001）相关。VLQI 与疾病严重程度呈显著相关（p = 0.015）。因子分析得出 6 个亚量表。
VLQI 是一种评估白癜风患者生活质量的有效、可靠的工具。
