Research Study

Specific Phobia of Vomiting Study

Update: The study has been completed.

Lori Riddle-Walker is conducting a research study on Specific Phobia of Vomiting (SPOV). SPOV is also known as emetophobia. This study is a randomized controlled trial (RCT) of cognitive behavioral therapy treating SPOV. The treatment is based upon the current research, both survey and case studies, including the work of David Veale, MD, a London-based psychiatrist who specializes in emetophobia, obsessive compulsive disorder, body dysmorphic disorder, health anxiety, and depression.

The study will be the first RCT for emetophobia. This is an important area of research that has been neglected. It has been estimated that over 8% of the population may suffer from a fear of vomiting (1) which can be chronic and debilitating. Emetophobia often co-occurs with depression, social anxiety disorder, and obsessive compulsive disorder.

The study is being done through Argosy University San Diego. It is being funded by the researcher and doctoral candidate, Lori Riddle-Walker, MA, LMFT. If you would like more information about the study, please sign up below to receive email updates.

Please see study participant recruitment information here, or download the flyer (PDF). Participants must be 18 or older and willing to travel to a clinic in San Diego County for assessments and 12 weekly sessions of cognitive behavioral therapy.

Research locations are in Escondido, Carlsbad and La Mesa. Call Lori at (760) 715-7273 to inquire.
