Bias in Mental Health Care of Children and Adolescents with Intellectual Disabilities Implicit and explicit bias and distortions of perception are partly responsible for the unequal and significantly deficient psychotherapeutic and psychiatric care situation for children and adolescents with intellectual disabilities and additional behavioral problems. The extent to which these biases influence misdiagnoses and treatment errors, refusals and exclusions from professional care, and grossly hostile rejections of people with disabilities requires empirical evidence (Bartig et al., 2021). The fact that all forms occur - probably to a considerable extent - contradicts the ethical principles of the medical and psychotherapeutic profession. In order to avoid misdiagnosis and treatment as a result of bias, this must be openly addressed. Selfawareness, supervision and second views, the concept of working diagnosis and, above all, the full application of child and adolescent psychiatric standards help to reduce bias.
