"DLQI Seems to be 'Action', and Skindex-29 Seems to be 'Emotion'": Qualitative Study of the Perceptions of Patients with Psoriasis or Eczema on Two Common Dermatology-specific Quality of Life Measures

Acta Derm Venereol. 2020 Apr 6;100(8):adv00105. doi: 10.2340/00015555-3417.

Abstract

Little is known about which quality of life measure best captures the lived experience of people with a chronic skin condition. The purpose of this study was to explore patients' views on the Dermatology Life Quality Index (DLQI) and Skindex-29. Participants were adults (n = 28) with a diagnosis of eczema or psoriasis who completed the DLQI and the Skindex-29 before being interviewed about the content and format of these questionnaires. Interviews were analysed using content analysis. Participants were generally satisfied with length and layout of both questionnaires. However, the majority preferred the Skindex-29 for its ease of understanding, use of a longer recall period and incorporation of items on a variety of emotions. Participants reported both questionnaires failing to incorporate important aspects of their lives, for instance impact on professional relationships. Participants voiced limitations in both measures but overall felt Skindex-29 better captured their lived experience.

Keywords: DLQI; Skindex-29; content validity; lived experience; qualitative study; quality of life.
