Numerous physical examination instruments are used to assess and measure severity of psoriasis and psoriatic arthritis (PsA) in practice and in clinical trials. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) has developed several online training modules used by GRAPPA members and investigators participating in psoriasis and PsA research. At the 2011 GRAPPA meeting, attendees were updated on the ongoing development of the training modules. ⋯ Each video includes the background and rationale for each measure, demonstration videos of select examinations, diagrams, and photographs to emphasize teaching points, and for most dermatology modules, an optional test to assess competence. Preliminary data generated by a pilot study of pre- and post-education PASI scoring by experienced and naive physicians and patient assessors were presented, revealing improved accuracy of scoring after viewing the PASI video. Attendees agreed that additional patient examples with more diverse skin types and psoriasis phenotypes, translation to languages other than English, and further validation studies are needed.
