Abstract summary
Mental disorders characterized by preoccupation with distressing bodily symptoms and associated functional impairment have been a target of major reconceptualization in the ICD-11, in which a single category of Bodily Distress Disorder (BDD) with different levels of severity replaces most of the Somatoform Disorders in ICD-10. This study compared the accuracy of clinicians' diagnosis of disorders of somatic symptoms using either the ICD-11 or ICD-10 diagnostic guidelines in an online study.Clinically active members of the World Health Organization's Global Clinical Practice Network (N = 1065) participating in English, Spanish, or Japanese were randomly assigned to apply ICD-11 or ICD-10 diagnostic guidelines to one of nine pairs of standardized case vignettes. The accuracy of the clinicians' diagnoses as well as their ratings of the guidelines' clinical utility were assessed.Overall, clinicians were more accurate using ICD-11 compared to ICD-10 for every presentation of a vignette characterized primarily by bodily symptoms associated with distress and impairment. Clinicians who made a diagnosis of BDD using ICD-11 were generally correct in applying the severity specifiers for the condition.This sample may represent some self-selection bias and thus may not generalize to all clinicians. Additionally, diagnostic decisions with live patients may lead to different results.The ICD-11 diagnostic guidelines for BDD represent an improvement over those for Somatoform Disorders in ICD-10 in regard to clinicians' diagnostic accuracy and perceived clinical utility.Study Outcome
