Schizoid Personality Disorder - Causes

Causes

There is some evidence to suggest that there is an increased prevalence of schizoid personality disorder in relatives of people with schizophrenia or schizotypal personality disorder. To Sula Wolff, who did extensive research and clinical work with children and teenagers with schizoid symptoms, "schizoid personality has a constitutional, probably genetic, basis." Other researchers had hypothesized that unloving, neglectful, or excessively perfectionist parenting could play a role.
