Psychotic disorders can be misunderstood or misdiagnosed by clinicians that deal with children, including clinical social workers, counsellors, child psychiatrists, and child psychologists. Many times it is difficult for a mental health professional to determine whether the problematic behaviours exhibited are the result of an altered normal developmental process or the result of a serious mental disorder. This book provides professionals and students with the specific information needed to better assess the exact nature of what is affecting the young patient.
