To quantify the impact of the mode of administration (MOA) on scores of the Vision Impairment in Low Luminance (VILL) questionnaire.
The VILL questionnaire was implemented using different MOAs (paper, interview, electronic), in addition to a demographical survey of adult participants recruited at an outpatient eye clinic, with the initial MOA being either paper or interview. Polytomous Rasch models were used to generate person measure scores for the three subscales of the VILL questionnaire (reading, VILL_R; mobility, VILL_M; and emotional, VILL_E). Measures of agreement among the different MOAs were calculated (self-administered paper/interview, self-administered paper/self-administered electronic, and interview/self-administered electronic). An age-matched analysis was performed to control for the impact of the initial MOA, administration interval, visual acuity, and self-reported hearing difficulties.
We included 309 participants (mean age, 63 ± 14 years; 61% female). Intra-class correlation coefficients were 0.930, 0.919, and 0.799 for paper versus interview assessment; 0.951, 0.959, and 0.916 for paper versus electronic; and 0.967, 0.955, and 0.907 for interview versus electronic assessment (VILL_R, VILL_M, and VILL_E, respectively). Mean differences were 0.35, 0.41, and 1.74 logits; 0.32, 0.18, and 0.68 logits; and 0.08, 0.22, and 0.63 logits, respectively. None of the mentioned factors significantly affected the results (corrected P ≥ 0.11).
Paper, interview, and electronic MOAs of the VILL can be considered equivalent. Reporting across the main MOAs of self-administration (paper) and interviewer-administration was unaffected by better eye visual acuity and self-reported hearing difficulties.
The results support use of the VILL questionnaire with flexible modes of administration.
量化给药方式（MOA）对低光照视力障碍（VILL）问卷评分的影响。
使用不同的 MOA（纸质、访谈、电子）实施 VILL 问卷，此外还对在门诊眼科诊所招募的成年参与者进行人口统计学调查，初始 MOA 为纸质或访谈。使用多分类 Rasch 模型为 VILL 问卷的三个子量表（阅读、VILL_R；移动性、VILL_M；和情绪、VILL_E）生成个人测量分数。计算了不同 MOA 之间的一致性度量（自我管理的纸质/访谈、自我管理的纸质/自我管理的电子、访谈/自我管理的电子）。进行了年龄匹配分析以控制初始 MOA、管理间隔、视力和自我报告的听力困难的影响。
我们纳入了 309 名参与者（平均年龄 63 ± 14 岁；61%为女性）。纸质与访谈评估的组内相关系数分别为 0.930、0.919 和 0.799；纸质与电子评估的组内相关系数分别为 0.951、0.959 和 0.916；访谈与电子评估的组内相关系数分别为 0.967、0.955 和 0.907（VILL_R、VILL_M 和 VILL_E）。平均差异分别为 0.35、0.41 和 1.74 对数单位；0.32、0.18 和 0.68 对数单位；0.08、0.22 和 0.63 对数单位。上述因素均无显著影响（校正 P ≥ 0.11）。
VILL 的纸质、访谈和电子 MOA 可视为等效。主要自我管理（纸质）和访谈者管理的 MOA 之间的报告不受更好的眼部视力和自我报告的听力困难的影响。
