About this trial
This study investigates whether caloric vestibular stimulation can modulate a measure of insight in obsessive-compulsive spectrum disorders.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18-65
Primary diagnosis of Obsessive-Compulsive Disorder, Body Dysmorphic Disorder, Illness Anxiety Disorder or Somatic Symptom Disorder (excluding "with predominant pain")
Strongly held OCRD-related concerns meeting BABS score criterion.
No recent change in psychopharmacological treatment, if any
Disqualifiers
Psychiatric or medical conditions (eg, vertigo, history of otological surgery) that might make participation unsafe
Pregnant or nursing women
Active or recent substance use
Trial design

Crossover
Treatments tested in this trial
Caloric Vestibular Stimulation
Other interventionCold water creates a convection current in the semicircular canal of the vestibular apparatus, leading to brief (\<3 min) and typically well tolerated sense of rotational movement. Similar stimulation is routinely used in standard vestibular diagnostic testing.
Treatment groups
16 Participants
are divided into 2 treatment groupsGroup A: right cold caloric vestibular stimulationExperimental treatment 1 intervention
Group B: left cold caloric vestibular stimulationExperimental treatment 1 intervention
Trial outcomes
Primary outcomes
1
change in clinical insight as measured by the Brown Assessment of Beliefs (BABS).
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.
