Foam Rubber Pica and Cautopyreiophagia in a Highly Educated Woman: A Clinical Case Study

Abstract

Pica, the developmentally and culturally-inappropriate eating of non-nutritive and non-food substances, is most often documented in people with developmental disabilities and children, frequently in institutional and residential settings. To date, there are no randomized clinical trials on pica-specific treatments, and very little literature is available regarding the characteristics or treatment of pica in adults with no intellectual or social deficits, and co-morbid disorders. This case study addresses this gap, and involves a highly educated 30 year-old American woman with foam rubber pica and burned match consumption (cautopyreiophagia) behaviors, along with co-morbid depressive, anxiety, and obsessive-compulsive symptoms, who received treatment in a general intensive outpatient program for adults in a large urban community psychiatry setting. The case study describes how the Biosocial Theory and Transtheoretical Model of Health Behavior Change were used to conceptualize this woman’s symptoms and guide a treatment team of clinicians who did not specialize in pica. Providers in non-specialty clinic settings would benefit from reflecting on ways to adapt evidence-based techniques to the treatment of uncommon symptoms.
