Research summary
FWhile there has been significant research on the physical and psychological impact of Functional Neurological Disorder (FND), few studies have explored the underlying mechanisms that perpetuate psychological distress in this population. Existing research has considered illness perceptions in FND but has not tested the mediational relationship proposed by the Common-Sense Model (CSM). Recent studies have also recommended further exploration of modifiable factors that can be targeted through interventions.
This study aims to apply the CSM to FND populations while examining psychological flexibility as a potential moderating factor. It will investigate how illness perceptions and coping styles contribute to psychological distress, focusing on maladaptive coping strategies. Understanding these relationships could help identify treatment targets to improve outcomes for individuals with FND. Psychological flexibility, in particular, may act as a protective factor, reducing the negative impact of threatening illness perceptions.
The study will use a cross-sectional, quantitative survey design, with illness perceptions as the predictor variable, maladaptive coping as the mediator, psychological distress as the outcome, and psychological flexibility as the moderator. Recruitment will be conducted online through social media, FND organizations, and NHS neurology and neuropsychology services. Participants will complete an anonymous online survey without providing identifiable information.
Should the findings confirm the hypothesis, the study could support the use of therapies such as Acceptance and Commitment Therapy (ACT) to reduce psychological distress in FND populations by enhancing psychological flexibility. Results will be analyzed using conditional process analysis, with the aim of uncovering specific intervention targets that could improve mental health outcomes for individuals with FND.
