An illustrated version of the Dermatology Life Quality Index (DLQI) was developed in order to improve the ease with which this standard questionnaire is answered.
To compare the illustrated version with the text-only version of the DLQI.
The two versions were administered to 206 patients attending Dermatology outpatient clinics. The time taken to complete either the illustrated or the text-only version was noted in 52 additional patients.
One hundred and ninety-one of 206 patients completed both questionnaires satisfactorily. Their mean DLQI scores were 6.4 (median 4.0, lower quartile 1.0, upper quartile 11.0) for the illustrated version and 6.3 (median 4.0, lower quartile 1.0, upper quartile 10.0) for the text-only version. For the 98 patients who answered the illustrated version first, the mean DLQI scores were 6.9 (median 4.0, lower quartile 1.9, upper quartile 11.9) for the illustrated version and 6.4 (median 4.0, lower quartile 1.8, upper quartile 11.0) for the text-only version. For the 93 patients who answered the text-only version first, the mean DLQI scores were 5.9 (median 4.0, lower quartile 1.7, upper quartile 10.2) for the illustrated version and 6.2 (median 5.0, lower quartile 0.5, upper quartile 9.5) for the text-only version. The median time taken to complete the text-only version was 124 s (mean +/- SD 126 +/- 65, n = 27) and 88 s (mean +/- SD 101 +/- 52, n = 25) for the illustrated version (P = 0.08). There was a very close correlation (r = 0.98) between the scores of the text-only and the illustrated versions; 82.2% of patients either scored the same or had a DLQI score difference of only 1. One hundred and seven (59.8%) patients preferred using the illustrated version and 66 (36.9%) preferred the text-only version. One hundred and four (57.5%) found the illustrated version easier to use.
The illustrated version was superior to the text-only version in terms of patient preference and ease of use, but it was not possible to demonstrate exact equivalence between the two versions.
为了提高这份标准问卷的作答便捷性，开发了一份《皮肤病生活质量指数》（DLQI）的图示版本。
比较DLQI的图示版本和纯文本版本。
将这两个版本发放给206名皮肤科门诊患者。另外52名患者记录了完成图示版本或纯文本版本所需的时间。
206名患者中有191名圆满完成了两份问卷。图示版本的平均DLQI得分为6.4（中位数4.0，下四分位数1.0，上四分位数11.0），纯文本版本为6.3（中位数4.0，下四分位数1.0，上四分位数10.0）。对于首先回答图示版本的98名患者，图示版本的平均DLQI得分为6.9（中位数4.0，下四分位数1.9，上四分位数11.9），纯文本版本为6.4（中位数4.0，下四分位数1.8，上四分位数11.0）。对于首先回答纯文本版本的93名患者，图示版本的平均DLQI得分为5.9（中位数4.0，下四分位数1.7，上四分位数10.2），纯文本版本为6.2（中位数5.0，下四分位数0.5，上四分位数9.5）。完成纯文本版本的中位数时间为124秒（均值±标准差126±65，n = 27），图示版本为88秒（均值±标准差101±52，n = 25）（P = 0.08）。纯文本版本和图示版本的得分之间存在非常紧密的相关性（r = 0.98）；82.2%的患者得分相同或DLQI得分差异仅为1。107名（59.8%）患者更喜欢使用图示版本，66名（36.9%）更喜欢纯文本版本。104名（57.5%）患者认为图示版本更易于使用。
在患者偏好和易用性方面，图示版本优于纯文本版本，但无法证明这两个版本完全等效。
