Schizoid Personality Disorder Diagnostic Criteria

Under the ICD approach, the formal diagnosis of schizoid personality disorder rests on these symptoms, which can be evaluated by psychiatrists and other mental health professionals. Also see the separate section on “DSM Approach to Schizophrenia”, which includes a page on the DSM approach to schizoid personality disorder.
