Supplementary Material for: Consumer Acceptance and Expectations of a Mobile Health Application to Photograph Skin Lesions for Early Detection of Melanoma

Background: Mobile teledermoscopy may facilitate skin self-examinations (SSEs) and further improve monitoring and detection of melanoma. Objective: To assess consumer acceptability and expectations of a mobile health app used to: (i) instruct SSE and (ii) conduct consumer-performed mobile teledermoscopy. Methods: People aged 18 years and above were invited to participate in either (i) an online survey or (ii) focus group in Brisbane, Australia. Participants were asked about their SSE practices, mobile teledermoscopy acceptance, and app design and functionality. The online survey responses and focus group discussions were coded by two researchers who conducted thematic analysis. Results: Four focus groups were held with a total of 28 participants; 88 participants completed the online survey. The mean ages of participants in the focus group and online survey were 46 and 38 years, respectively. There were more males in the focus groups (61%, 17/28) compared to the online survey (19%, 17/88). Regular SSEs were conducted by 56 (64%) of the online survey participants. Barriers to SSE were forgetfulness (44%), low self-perceived risk of melanoma (25%) and low confidence in conducting SSEs (25%). The large majority of online survey participants (95%) would consider sending photos of their skin lesions to a medical practitioner via an app. Focus group participants reported that they would accept using mobile teledermoscopy; however, they would prefer to use it to monitor lesions between face-to-face consultations. Conclusions: Overall, participants had positive views on using mobile teledermoscopy to send images of skin lesions to a dermatologist or other medical practitioner.

背景：移动远程皮肤镜检查可能有助于促进皮肤自我检查（SSE）并进一步改善黑色素瘤的监测与检测。研究目的：评估用于指导SSE和执行消费者移动远程皮肤镜检查的移动健康应用程序的可接受性和用户期望。研究方法：邀请18岁及以上的成年人参与以下任一活动：（i）在线调查或（ii）在澳大利亚布里斯班进行的焦点小组。参与者被询问其SSE实践、移动远程皮肤镜检查的可接受性以及应用程序的设计和功能。在线调查的回应和焦点小组讨论由两位研究人员进行编码，并进行了主题分析。研究结果：共举办了四个焦点小组，共有28名参与者；88名参与者完成了在线调查。焦点小组和在线调查参与者的平均年龄分别为46岁和38岁。焦点小组中男性参与者比例（61%，17/28）高于在线调查（19%，17/88）。56名（64%）的在线调查参与者定期进行SSE。SSE的障碍包括遗忘（44%）、自我感知黑色素瘤风险低（25%）和进行SSE的自信心不足（25%）。绝大多数在线调查参与者（95%）考虑通过应用程序将皮肤病变照片发送给医疗保健提供者。焦点小组参与者表示，他们愿意使用移动远程皮肤镜检查；然而，他们更愿意在面对面咨询之间用它来监测病变。研究结论：总体而言，参与者对使用移动远程皮肤镜检查将皮肤病变图像发送给皮肤科医生或其他医疗保健提供者的做法持积极态度。
