It has become an important space for sharing information on a wide range of topics, including medical conditions such as atopic dermatitis (AD). Advice on skin conditions has become popular on TikTok, and most previous research in this area focuses on the credibility of the information being shared. However, little research has focused specifically on physician-created videos and their audience engagement and interaction.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n Our study aimed to (1) characterize the audience\u2019s online response to board-certified physicians\u2019 TikTok content related to AD according to established protocols and (2) better understand the interactions that happen among members of the audience in the comment section of this content.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n In December 2023, searches were conducted for the terms \u201catopic dermatitis\u201d and \u201ceczema\u201d on 3 unique TikTok accounts to identify videos created about AD by board-certified dermatologists. A total of 28 final videos were analyzed and classified into the following categories: (1) explanation of disease, (2) recommendation, (3) debunking misinformation, and (4) informal or anecdotal. The top 50 original comments on each of the 28 videos were collected and classified into one of the following categories: (1) \u201cpositive personal experience,\u201d (2) \u201cnegative personal experience,\u201d (3) \u201cneutral personal experience,\u201d (4) \u201crequesting advice,\u201d (5) \u201clearning,\u201d (6) \u201cappreciative reaction,\u201d (7) \u201ccritical reaction,\u201d (8) \u201cgiving advice,\u201d (9) \u201chumor,\u201d (10) \u201ctagging another user,\u201d and (11) \u201coff-topic.\u201d Replies to comments were also analyzed and grouped into similar categories.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Video category did not have a significant impact on engagement rate (\n P<\/jats:italic>\n >.99). Across all video categories, comments that involved personal experiences or sharing information made up a larger percentage than those that were critical or off-topic (\n P<\/jats:italic>\n <.001). Of the comments related to personal experience, the percentage of negative personal experience comments was significantly higher than that of positive personal experience comments (\n P<\/jats:italic>\n =.001). Among replies to comments, \u201crecommendation\u201d and \u201cemotional support\u201d replies were significantly more common than other types of replies (\n P<\/jats:italic>\n <.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Our study suggests that videos created by dermatologists on TikTok are generally well received regardless of video style or category. The comment sections appear to provide transient supportive environments where users connect over shared challenges and exchange personal experiences and recommendations. There is a gap in dermatologist-produced TikTok content involving darker skin tones.<\/jats:p>\n
