Reconceptualizing emetophobia: A cognitive–behavioral formulation and research agenda

Fear of vomiting (emetophobia) is a poorly understood anxiety disorder, with little research published into its conceptualization or treatment. The current article uses established cognitive and behavioral models of other anxiety disorders as a basis from which to propose a detailed model of emetophobia. The model proposes that emetophobia results from a constellation of factors including a general anxiety-vulnerability factor, a tendency to somatize anxiety as gastrointestinal distress, a tendency to catastrophically misappraise nausea and other gastrointestinal symptoms, hypervigilance to gastrointestinal cues, beliefs about the unacceptability of vomiting, negatively reinforced avoidance behavior, and selective confirmation biases. A formulation-based treatment package for emetophobia is outlined, including arousal management skills, distraction/attention training, exposure and cognitive restructuring.
