Caloric Vestibular Stimulation for Obsessive-Compulsive Spectrum Disorders

This study is exploring if a treatment called Caloric Vestibular Stimulation can improve insight in people with obsessive-compulsive spectrum disorders. This involves using cold water to create a brief, mild sensation of spinning, similar to a test doctors already use. The study is looking for 16 participants aged 18 to 65 who have been diagnosed with Obsessive-Compulsive Disorder, Body Dysmorphic Disorder, or Illness Anxiety Disorder, and who meet specific criteria for their beliefs related to these conditions. The main goal is to see how much your insight changes after one hour, as measured by a specific assessment tool. The current recruitment status is unclear.

What this trial measures

  • change in clinical insight as measured by the Brown Assessment of Beliefs (BABS).1 hour

    Changes in clinical insight will be rated using the BABS, a gold-standard measure for assessing multiple dimensions of clinical insight across psychiatric disorders. The BABS is a 24 point scale for which scores ≥13 suggest poor or absent insight.
