It also reduces the patients&rsquo; quality of life and requires a long-term management. Therefore, in addition to appropriate treatment of the disease, self-management strategies to improve patient health and quality of life are essential. On the other hand, smartphone-based applications alter the way people interact with health care and public health systems. This study aimed at identifying training and informational components to develop a psoriasis self- management application.<br> <strong>&nbsp;&nbsp; Methods:</strong> This descriptive-analytic study was conducted on 100 patients with psoriasis and 26 dermatologists who were selected randomly, using Morgan table. The data were collected using a researcher- made questionnaire, which included demographic and clinical information, lifestyle training and management, and application capabilities in psoriasis self-management. A group of experts and a test-retest method were used to confirm the validity and reliability of the questionnaire, respectively.<br> <strong>&nbsp;&nbsp; Results:</strong> The mean scores for demographic and clinical information, lifestyle training and management, and application capabilities in self-management were 80.55%, 85.7%, and 88.8% from the patients&rsquo; perspective, and 83.7%, 71%, and 75% from the specialists&rsquo; viewpoint, respectively.<br> <strong>&nbsp;&nbsp; Conclusion: </strong>Determining self-management components by patients as persons who are suffering from the disease and physicians as specialists in the field will be helpful in efficient psoriasis self-management. It is more likely that self-reliant patients, who are aware of the benefits and risks of their disease management application, will follow their treatment plan and pursue the management of their disease more seriously.<br> &nbsp;<br> &nbsp;</p> Psoriasis, Self-management, Application 383 390 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-3027-1&slc_lang=en&sid=1 Reza Safdari rsafdari@tumas.ac.ir 200319475328460034049 200319475328460034049 No Health Information Department, Health Information Management Research Center, School of Allied Medical Sciences, Tehran University of Medical Sciences, Tehran, Iran.
