In representative samples of children and adolescents, on average, 2% are affected by Internet gaming disorder (IGD). The mean prevalences (overall, clinical samples included) reach 5.5%. Definitions are heterogeneous and the relationship with substance-related addictions is inconsistent. Many aetiological factors are related to the development and maintenance of IGD. This review presents an integrated model of IGD, delineating the interplay of these factors.

Because the comorbidity rate is high, screening for psychological symptoms is recommended for all children in all settings with enuresis and/or daytime urinary and/or fecal incontinence. Standardized, validated questionnaires are recommended. In addition to clinical observation and history, a short screening questionnaire can be used as a first step. If problem behaviors are present a longer broadband questionnaire is recommended. If problem items in the clinical range are noted, a full child psychiatric or psychological assessment is recommended.
