Objectives: To study the relation between obsessive-compulsive symptoms (OCS) and positive, negative, and depressive symptoms in patients with recent-onset schizophrenic disorders.
Methods:We undertook a prospective study of 113 consecutively hospitalized patients with recent-onset schizophrenia or related disorders diagnosed according to DSM-IV criteria. We compared 3 subgroups: one without comorbid OCS, one with OCS not fulfilling DSM-IV criteria for obsessive-compulsive disorder (OCD), and one with comorbid OCD diagnosed according to DSM-IV criteria. We assessed OCS severity at admission and 6 weeks thereafter with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). The Positive and Negative Syndrome Scale (PANSS) and the Montgomery-Asberg Depression Rating Scale (MADRS) were independently administered.
Results:At admission, patients with schizophrenic disorders and OCD had higher mean MADRS scores than both other groups; patients with OCS not fulfilling DSM-IV criteria for OCD had lower mean PANSS negative subscale scores than both other groups. After 6 weeks, there were no significant between-group differences, and OCS severity remained constant.
Conclusions:Acute patients with recent-onset schizophrenia and OCD have more severe depressive symptoms but do differ in negative symptoms, compared with patients without comorbid OCD. Mild OCS may be related to less severe negative symptoms. During regular inpatient treatment, OCS severity remains constant.(Can J Psychiatry 2005;50:519-524)Information on funding and support and author affiliations appears at the end of the article.Clinical Implications · Acute patients with recent-onset schizophrenia and OCD...
