Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Participants with Psoriasis
People who report a diagnosis of Psoriasis. Participants are invited via the Psorcast mobile application to complete the following assessments: Participant self-assessment surveys, skin assessments (Psoriasis Area Draw and Psoriasis Area Photo) and musculoskeletal assessments (Finger/Toe Photos, Joint Count, Digital Jar Open, 30s Walk).
Participant self-assessment surveys
At enrollment, participants are asked to complete a baseline health history, family history, and a participant-reported symptom inventory.
Psoriasis Draw
Participants are asked to draw the location and size of psoriasis they currently experience. Participants are provided a body template onto which they can draw on their screen. Investigators estimate the percentage of body area affected.
Psoriasis Area Photo
Participants are asked to take a picture of a representative psoriasis plaque and indicate the location of the plaque. They are asked to take a picture of the same area over time. The investigators are developing computer vision algorithms to assess the plaque.
Finger and Toe Photos
Participants are asked to take pictures of the back of each hand and the top of each foot. These photos can be used to assess finger and toe swelling as well as psoriatic nail involvement. The investigators are developing computer vision algorithms to assess psoriatic nail involvement and digit swelling.
Digital Jar Open
Participants are asked to internally and externally rotate the phone as it rests on a flat surface. Participants perform each direction (internal and external) and each arm (left and right) in turn. Gyroscope sensors measure the degree of rotation.
30 Second Walk
Participants are asked to walk in a straight line for 30 seconds. Gait is measured by gyroscope and accelerometer sensors. The investigators examine step-dependent and sequence-dependent features from these sensors. The investigators apply feature selection and classifier algorithms to analyze these data.
Psorcast mobile application
Participants complete all described behavioral interventions via a dedicated iPhone app, Psorcast.
Participants with Psoriatic Arthritis
People who report a diagnosis of Psoriatic Arthritis. Participants are invited via the Psorcast mobile application to complete the following assessments: Participant self-assessment surveys, skin assessments (Psoriasis Area Draw and Psoriasis Area Photo) and musculoskeletal assessments (Finger/Toe Photos, Joint Count, Digital Jar Open, 30s Walk).

Participants without Psoriasis or Psoriatic Arthritis
People who report no prior diagnosis of Psoriasis or Psoriatic Arthritis. Participants are invited via the Psorcast mobile application to complete the following assessments: Participant self-assessment surveys, skin assessments (Psoriasis Area Draw and Psoriasis Area Photo) and musculoskeletal assessments (Finger/Toe Photos, Joint Count, Digital Jar Open, 30s Walk).
