Body dysmorphic disorder (BDD) is common and can have a devastating impact. However, existing data suggest that the condition often goes undiagnosed and untreated. This study will quantitatively examine diagnostic and treatment decision-making among clinicians working in Child and Adolescent Mental Health Services (CAMHS) within the National Health Service (NHS). This study will use a cross-sectional, online survey design. We will aim to recruit five hundred clinicians who will receive two fictional case vignettes. In one vignette the material will describe an adolescent with BDD, and in the other vignette the material will describe an adolescent with obsessive-compulsive disorder (OCD). We will randomly allocate clinicians to receive two vignettes of a cisgender male, or two vignettes of a cisgender female. We will examine clinicians’ accuracy in identifying BDD and OCD from the vignette and whether this varies by the person’s sex. For the BDD vignette specifically, we will explore whether clinician characteristics are associated with diagnostic decisions, and report psychological treatments recommendations. Data will be analysed in an anonymised format and will only be accessed by members of the research team. Only aggregate data will be disseminated outside the team (e.g. publication in peer-reviewed journal, presentation at conferences). This will be the first study to directly assess clinician-reported practices in relation to BDD. The results will provide crucial insight in the training needs of CAMHS clinicians in England, with respect to BDD detection, diagnosis and psychological treatment. This will inform where training is best targeted (e.g. which professional groups) and also shape the content of training (i.e. focus on diagnosis and/or treatment).
