Patient preferences for psoriasis treatment: process characteristics considered more important than outcome attributes

In a recent paper by Schaarschmidt et al., patients with moderate-to-severe psoriasis completed a conjoint analysis survey (discrete choice experiment) to determine which factors had influenced their choice of treatment, and the relative importance of each factor. They also assessed how socioeconomic and demographic factors affected patient choice. Using relative importance scores, treatment location was found to be the more important attribute to patients, followed by probability of benefit and method of delivery.
