Use of SF-12 Questionnaire to Assess Status in Patients With Psoriasis

A general health measure such as the 12-item Short Form Health Survey (SF-12) can adequately capture in patients with psoriasis, the burden of the disease both from a physical and a mental point of view. This according to observational study conducted among outpatients with mild-to-severe psoriasis. Health status was assessed by the SF-12, which includes a physical (PCS) and a mental (MCS) scale. Researchers found:

  • The study population included 1,592 patients.
  • Psoriasis PCS scores were similar to the general population and to non-severe diseases such as allergies, dermatitis, or back pain
  • MCS mean scores were very similar to that of depression, and lower than those of all other chronic conditions.
  • Poor physical health was associated with female sex, older age, lower educational level, joint involvement, ≥2 comorbidities, moderate to very severe clinical status, and moderate to severe Skindex-17 psychosocial scores.
  • Poor mental health was associated with younger age, GHQ ≥4, and severe Skindex-17 psychosocial scores.
