PY - 2017 DA - 2017/09/12 TI - The content validity of the PSS in patients with plaque psoriasis JO - Journal of Patient-Reported Outcomes SP - 4 VL - 1 IS - 1 AB - The primary objective of this study was to evaluate the content validity of the Psoriasis Symptom Scale (PSS), with a specific focus on understanding of the content of the PRO measure by conducting one-on-one interviews with patients with moderate to severe plaque psoriasis. This was a cross-sectional, qualitative study conducted with 20 patients with plaque psoriasis who participated in in-person, one-on-one interviews. Participants were asked to describe their psoriasis symptoms, completed the PSS, and were cognitively debriefed on its content. Interviews were conducted in two separate rounds. Following Round 1, the study data were examined to determine if modifications to the PSS were required. All interviews were audio-recorded and transcribed. Sociodemographic and clinical data were collected for sample descriptive purposes. SN - 2509-8020 UR - https://doi.org/10.1186/s41687-017-0004-7 DO - 10.1186/s41687-017-0004-7 ID - Rentz2017 ER -
