BackgroundThe Food and Drug Administration patient-reported outcome (PRO) guidance provides standards for PRO development, but these standards bring scientific and logistical challenges which can result in a lengthy and expensive instrument development process. Thus, more pragmatic methods are needed alongside traditional approaches.MethodsPartnering with the National Ankylosing Spondylitis (AS) Society, we compared three methods for eliciting patient experiences: 1) concept elicitation (CE) interviews with 12 individuals with AS, 2) “group concept mapping” (GCM) with 16 individuals with AS, 3) a social media review (SMR) of AS online chatrooms. Three conceptual models were developed and compared to explore data breadth/depth, as well as the practicalities and patient-centeredness.ResultsOverlap in concepts was observed between conceptual models; 35% of symptoms were identified by all methods. The SMR approach identified the most concepts (n = 23), followed by CE interviews (n = 18), and GCM (n = 15). Eight symptoms were uniquely identified using GCM and SMR. Eliciting in-depth data was challenging for SMR as detail was not always provided. Insight into the relationships between symptoms was obtained as a “concept map” in GCM, via effective probing within interviews, and through the subject’s descriptions in SMR. Practical investment varied; CE interviews were the most resource intensive, whereas SMR was the least. Individuals in GCM and CE interviews reported high engagement.ConclusionsPrimary CE interviews achieved the greatest depth in conceptual understanding of patient experience; however, novel methods (GCM, SMR) provide complementary approaches for identifying measurement concepts. Each method has strengths and weaknesses and should be selected based on specific research objectives.Electronic supplementary materialThe online version of this article (10.1186/s41687-017-0013-6) contains supplementary material, which is available to authorized users.
