[Obsessive phenomena in schizophrenic adolescents].

Adolescent schizophrenics show obsessive-compulsive symptoms as often as adult patients. Obsessive-compulsive symptoms occur generally both in premorbid and post-acute states, whereas they are rarely observed in acute states. A particular preference of any schizophrenic subgroup doesn't seem to exist. Obsessive-compulsive phenomena are not the same as coping-techniques or (pseudo)-neurotic defense mechanisms, and don't allow a prediction of a distinct outcome. The relationship between schizophrenia and obsessive-compulsive symptoms is variable, and doesn't follow a set pattern.
