Introduction: Hidradenitis Suppurativa (HS) has been associated with impaired quality of life (QoL). There are various measuring systems to assess physical severity; however, there are no specific QoL questionnaires for this disease in the Spanish language.
Objective: To develop and validate a disease-specific instrument to measure QoL in patients with HS.
Methods: A literature search was carried out to prepare a semi structured interview for patients with HS, as well as a Delphi expert consensus among health professionals. The validation with a sample of 130 patients is presented. The preliminary validation of the HSQoL-24 was passed twice to a group of 30 patients with 30 ± 10 days of interval. The DLQI and the Skindex-29 were used for its validation.
Results: Cronbach alpha 0.87 indicates a good internal consistency of the questionnaire. The intraclass correlation coefficient (ICC) with the DLQI was 0.70 (p-value) (< 0.001), and 0.87 (p-value) (< 0.001) with the Skindex-29.
Conclusions: The HSQoL-24 is the first specific self-administered questionnaire to assess QoL in patients with HS in Spanish. It is user friendly and easy to. This study demonstrates the excellent properties of the instrument: comprehensibility, reliability (test-retest), internal consistency, validity, comparison with DLQI and SKINDEX-29, and discriminative capacity.
