The stigma associated with the autoimmune disease psoriasis may lead people to avoid patients who show signs of the condition, including not wanting to date, shake hands, or have people in their homes if they suffer from the disease, according to a new study.
New research involving both psychologists and dermatologists from the Perelman School of Medicine at the University of Pennsylvania is the first to examine how common this stigma may be among the general population of the United States, as well as among medical students, researchers said.
The study also found false perceptions about psoriasis continue to persist, including the belief that psoriasis is contagious and that it is not a serious illness, researchers added.
Psoriasis is a common, chronic autoimmune disease affecting more than 8 million Americans, causing painful, thick, red patches on the skin that often itch and bleed.
It has profound effects on health-related quality of life, and in moderate to severe cases, it carries an increased risk of heart attack, stroke, and premature death. It is not contagious, and while it is treatable, there is currently no cure, researchers note.
“Although it’s widely recognized that the appearance of psoriasis can negatively impact patients’ social, professional, and intimate relationships, we wanted to quantify the perceptions patients with psoriasis face on a daily basis in order to understand how pervasive they are,” said the study’s senior author Joel M. Gelfand, M.D. M.S.C.E., a professor of dermatology and epidemiology at Penn.
Researchers used Amazon Mechanical Turk (MTurk), a web-based data collection service, to survey people about their perceptions of individuals with psoriasis. They also sent the survey directly to several hundred medical students.
In all, 198 people responded on MTurk and 187 medical students completed the emailed survey. All participants were shown images of people with psoriasis, as well as close-up photos of psoriasis lesions, the researchers explained.
Overall, 54 percent of people who responded through MTurk said they did not want to date someone with psoriasis. Thirty-nine percent said they did not want to shake hands with someone suffering from the disease, while 32 percent said they did not want to have someone with psoriasis in their homes.
They also endorsed several stereotypes about people with psoriasis, with 57 percent saying they were insecure, 53 percent saying they were sick, 45 percent saying they were unattractive, and 27 percent saying they were contagious, according to the studyâ€™s findings.
Medical students demonstrated less stigmatizing views compared to the MTurk group. Among MTurk participants, those who knew someone with psoriasis or had heard of psoriasis demonstrated less stigmatizing attitudes, the researchers discovered.
“It’s possible that better education about the disease, as well as contact with individuals with psoriasis, may help to dispel myths and stereotypes and reduce negative perceptions,” said Rebecca L. Pearl, Ph.D., an assistant professor of psychology, who was the lead author of the study.
The study was published in the Journal of the American Academy of Dermatology.
