Schizoid is a pervasive pattern of detachment from social relationships, social isolation and a restricted range of expressing emotions in interpersonal settings. Pattern begins in early adulthood. Does not occur exclusively with schizophrenia, but may also appear with another psychotic disorder or a pervasive developmental disorder.
Schizoid behavior is indicated by four or more of the following:
• neither desires nor enjoys close relationships, including being part of a family
• almost always chooses solitary activities
• has little, if any, interest in having sexual experiences with another person
• takes pleasure in few, if any, activities
• lacks close friends or confidants other than first-degree relatives
• appears indifferent to the praise or criticism of others
• shows emotional coldness, detachment or flattened affectivity
