They are also [[Secrecy|secretive]] and don't show many [[Emotion|emotions]]. It is often shortened to SzPD or SPD. This condition is not [[schizophrenia]]. People with SzPD will typically share some of the [[symptom]]s of schizophrenia. However, schizoids do not have the positive symptoms of schizophrenia such as [[hallucination]]s. A negative symptom is one that is taken away from a person. A positive symptom is one that is added to a person. People who have SzPD do not want [[interpersonal relationship]]s which require [[emotion]] and commitment. People with SzPD are [[introvert]]s who feel the need to be independent or alone. Many schizoids are [[asexual]] or have little interest in sexual encounters. Any relationships they may have probably does not involve emotional attachment. SzPD is more common in men than women.<ref>Coid, Jeremy; Yang, Min; Tyrer, Peter; Roberts, Amanda; Ullrich, Simone 2006. Prevalence and correlates of personality disorder in Great Britain.
