Obsessive compulsive symptoms are related to lower quality of life in patients with Schizophrenia.

Background: The aim of this study is to investigate the effects of obsessive-compulsive symptoms (OCS) on quality of life (QoL) and to identify the OCS with a particular effect on QoL, and whether there are any such symptoms for patients with schizophrenia.

Methods: We studied three groups of patients with schizophrenia. One group of patients (n = 45) without OCS or obsessive-compulsive disorder (OCD), one group with OCS, not fulfilling the diagnostic criteria for OCD (n = 31), and one group with OCD as a comorbid condition (n = 24).

Obsessive compulsive disorder and symptoms may have different effects on schizophrenia.

The aim of this study is to investigate the possible different effects of obsessive compulsive disorder (OCD) and obsessive compulsive symptoms (OCS) on schizophrenia illness in regard to clinical characteristics such as severity of symptomatology. We included 184 patients with schizophrenia on monotherapy with a stable dose of antipsychotics for at least three months. Severity of clinical symptoms was evaluated by Positive and Negative Syndrome Scale.
