title: Translation into Brazilian Portuguese and validation of the psoriasis family index.
abstract: Psoriasis Family Index is a quality of life instrument for family members of patients with psoriasis developed in English. The aims of this study were to translate the Psoriasis Family Index into Brazilian Portuguese, culturally adapt it and verify its reliability and validity. The study followed these two steps: 1) Translation, linguistic and cultural adaptation, 2) Validation. The translated Psoriasis Family Index showed high internal consistency and high test-retest reliability, confirming its reproducibility. The Portuguese version of the Psoriasis Family Index was validated for our population and can be recommended as a reliable instrument to assess the QoL of family members and partners of patients with psoriasis.
