Schizoid personality disorder (SPD) is a Cluster A Personality Disorder characterized by a pervasive pattern of detachment from social relationships and a restricted range of emotional expression in social settings.
SPD has been conceptualized as deficits in the following areas:
- Self-concept – such as feelings of inferiority
- Interpersonal relations – such as fear of intimacy
- Social adaptation – such as preference for solitary occupational and recreational activities
- Love and sexuality – such as celibacy
- Ideals – such as a tendency toward spirituality and mysticism
- Cognitive style – such as engrossed in fantasy
SPD affects approximately 1% of the general population and it is more common in males than in females. The onset of symptoms of SPD typically starts in late childhood or adolescence.
