Research paperModification of the medical exclusion criterion in DSM-5 social anxiety disorder: Comorbid obesity as an example

- Patients with SAD reported more binge/emotional eating vs. those with no disorders.
- Similar results were found in patients with modified SAD vs. no disorders.
- The modified SAD group more closely resembled the DSM-IV SAD group.
- Results support diagnosing SAD in those with weight-related fears only.

BackgroundThe DSM 5 modified the medical exclusion criterion from DSM-IV, which now allows for a diagnosis of social anxiety disorder (SAD) to be given if the fears are related only to the medical condition (e.g., obesity) yet cause significant impairment or distress.MethodsTo examine this modification, the current study compared bariatric surgery candidates with DSM-IV SAD (n=135), modified SAD (clinically significant social fears related to obesity only; n=40), and no history of Axis I disorders (n=616) on variables related to pre-surgical problematic eating behaviors, body image dissatisfaction, functional impairment, and other characteristics related to bariatric surgery. Participants were referred by their surgeon for a psychiatric evaluation as part of the clearance process, and completed a comprehensive, semi-structured diagnostic interview and self-report measures.ResultsThere were several differences between those with DSM-IV SAD and modified SAD compared to those with no disorder (e.g., on binge and emotional eating), but the two SAD groups did not differ from each other on any of the comparisons.LimitationsResults may not generalize to individuals suffering from obesity in the general population or those seeking other types of weight loss treatment. Because they were seeking psychiatric clearance, they also may have underreported symptoms/problems for fear that they would not get cleared.ConclusionsOverall, the modified SAD group more closely resembled the DSM-IV SAD group rather than the no disorder group, providing further support for diagnosing SAD even when the social fears are related to obesity only.
