A compact, “how-to” manual on effective, evidence-based treatments for enuresis and encopresis. The aim of this book is to provide readers with a practical overview of the definitions, characteristics, theories and models, diagnostic and treatment recommendations, and relevant aspects and methods of evidence-based psychosocial treatments for encopresis and enuresis, primarily in children. Although treatments and research for elimination disorders are reviewed in general, particular attention is directed at constipation and encopresis, toileting refusal, and diurnal and nocturnal enuresis due to the high incidence of these conditions in children. Case vignettes, websites, and suggestions for further reading are provided for the interested reader.
