The specific cause of this disorder is unknown. It appears to be more common in families with psychotic disorders such as schizophrenia and delusional disorder, which suggests that genes may be involved. Paranoid personality disorder can result from negative childhood experiences fostered by a threatening domestic atmosphere. It is prompted by extreme and unfounded parental rage and/or condescending parental influence that cultivate profound child insecurities.
