One-hundred patients completed a questionnaire designed to assess the disability resulting from acne; patient acne severity was also graded clinically. Ten questions which correlated strongly with clinical acne severity were used to form an Acne Disability Index (ADI). This ADI correlated with the severity of facial acne (r = 0.246, P less than 0.01), chest acne (r = 0.347, P less than 0.001) and back acne (r = 0.436, P less than 0.001). Measures were made of the financial value to patients of acne treatment: when hypothetically offered either a cure for their acne or 500 pounds, 87% of patients preferred the treatment rather than the money. All 13 patients who stated a preference for the 500 pounds had minimal acne. There is no correlation between the clinical grading of acne and the amount patients would be prepared to pay for a hypothetical cure but there is a correlation between the acne disability score and the amount patients would pay (r = 0.229, P less than 0.05).
100名患者完成了一份旨在评估痤疮所致残疾的问卷；同时对患者的痤疮严重程度进行了临床分级。选取了与临床痤疮严重程度密切相关的10个问题，用于构建痤疮残疾指数（ADI）。该ADI与面部痤疮严重程度相关（r = 0.246，P < 0.01），与胸部痤疮严重程度相关（r = 0.347，P < 0.001），与背部痤疮严重程度相关（r = 0.436，P < 0.001）。对痤疮治疗对患者的经济价值进行了评估：假设给患者提供痤疮治愈方案或500英镑，87%的患者选择治疗而非金钱。所有表示偏好500英镑的13名患者痤疮都很轻微。痤疮的临床分级与患者愿意为假设的治愈方案支付的金额之间没有相关性，但痤疮残疾评分与患者愿意支付的金额之间存在相关性（r = 0.229，P < 0.05）。
