Illness perceptions in functional neurological disorder: a ‘think-aloud’ study of the Revised Illness Perception Questionnaire using content and thematic analysis

Co-produced qualitative work should explore different FND subtypes at serial timepoints in treatment to adapt the IPQ-R as a meaningful and sensitive measure for FND, which considers neurodivergent people and trauma survivors.
