Rethinking psychological treatment targets for pediatric rumination syndrome: Clinical implications from a case series analysis

Abstract

Rumination syndrome (RS) is a common pediatric disorder of gut-brain interaction. However, a dearth of research on efficacious treatment to help guide clinical decision-making remains. Thus, relying on well-established treatment recommendations for other conditions with similar mechanisms or symptom profiles may be helpful; for example, conceptualizing RS treatment targets to address it as a "tic disorder of the gut" could be beneficial. To demonstrate the clinical utility of this conceptualization, we presented two cases that provide broad implications for treating pediatric RS. In both cases, akin to pediatric tic and related disorders, cognitive distress and physical discomfort were alleviated temporarily by rumination episodes. Thus, we recommend a targeted diagnostic assessment, including a functional analysis incorporating a transdiagnostic evaluation of symptoms. Close comanagement with specialty physicians and psychologists is also highly recommended. The patients represent complex yet standard cases seen in pediatric psychology outpatient clinics, suggesting the clinical utility of implications for psychologists and allied health professionals.
