ObjectivesIndividuals with a diagnosis of FND report experiencing stigma in medical settings, however, there is a paucity of research exploring their experiences in psychological services. The aim of this research was to explore experiences of accessing UK psychological services, from the perspective of those with FND.MethodsThis study utilised a qualitative approach with data collected from semi‐structured interviews (n = 15) and analysed using reflexive thematic analysis.ResultsOne superordinate theme, ‘the stigmatised self within the therapeutic relationship’, and five interrelated subthemes were identified: ‘internalised stigma and self‐doubt’, ‘selective disclosure to professionals’, ‘perceptions of psychological explanations’, ‘having to educate the professionals’ and ‘attunement and trust within the therapeutic relationship’. Positive therapeutic relationships were perceived to mitigate the impact of these perceived barriers. The conceptualisation of FND and the perception of how this was responded to by services and professionals was a central tenet throughout the related themes.ConclusionsIntra‐personal, interpersonal and organisational stigma impact access and engagement to psychological treatment. The findings of this study highlight the need for increased training provision for practitioners with a focus on actively challenging FND stigma within services at both an individual and systemic level.
