What Would we Like to (Diagnose) and what do we have to Diagnose. A Systemic Overview and Perspective Behavioral problems in children and young people are currently quickly suspected of being a sign of a psychological problem or a psychiatric disorder. In many cases, the caregivers agree on this, but in others there are clearly different perspectives from obvious to possible diagnoses. Whether a diagnosis makes sense and whether appropriate diagnostics are effective depends on various factors. From a systemic perspective, the common process, the symptomatic patients and their environment benefit from a solution- and resource-oriented view, which should have a greater impact on the future design of classifications of health and illness.
