"I still can't forget those words": mixed methods study of the persisting impact on patients reporting psychosomatic and psychiatric misdiagnoses.

Objectives: This research aimed to improve understanding of persisting impacts of patient-reported psychosomatic and psychiatric misdiagnoses on patients with systemic autoimmune rheumatic diseases (SARDs).

Methods: Mixed methods data from two SARDs cohorts were analysed (N = 1,543 and N = 1,853). Validated instruments and patient-designed questions were used to measure self-reported depression, anxiety and mental wellbeing, in addition to medical relationships and healthcare behaviours.
