“…A Turkish study reported the most common anxiety disorder to be obsessive compulsive disorder (39.0%), followed by social phobia with a prevalence rate of 13.4% 8 . Other studies reported specific prevalence of social phobia (17%), obsessive compulsive disorder (15.1%), generalized anxiety disorder (9.4%), panic disorder (5.7%), specific phobia (5.7%) and 1.9% for agoraphobia 11 .…”

“…A study carried out in Brazil reported that at least 51% of patients with schizophrenia met criteria for at least one form of anxiety disorder 6 . In Turkey, a study that recruited 82 out-patients with schizophrenia diagnosed fifty-five (67.1%) with at least one lifetime co-morbid anxiety disorder 8 . A work that studied racial disparity in the rate of diagnosis of anxiety disorder in Caucasians and African-Americans reported an anxiety disorder di-agnosis rate of 27% in Caucasians and 13% in African Americans.…”

“…A high positive correlation was also reported between the severity of anxiety symptoms and positive symptoms in schizophrenia 21 . However some studies have found patients with a diagnosis of schizophrenia with co-morbid anxiety disorder to have a shorter duration of illness compared to those without such co-morbid condition 8 . Another study by Lysaker et al among patients with obsessive compulsive symptoms found no correlation between the presence of anxiety symptoms and the severity of positive psychotic symptoms in schizophrenia 22 .…”

Background: Anxiety disorders occur commonly in schizophrenia but are often overlooked by psychiatrists. Their presence may compound the challenges faced by these patients and may contribute to poor outcome. Objectives: The purpose of this study was to determine the prevalence of anxiety disorders among the participants with schizophrenia, and the association between this co-morbidity and disability. Method: A total of 367 participants were recruited from the out-patient department of Federal neuropsychiatric hospital Enugu, Nigeria. Socio-demographic questionnaire, schedules for clinical assessment in neuropsychiatry, positive and negative syndrome scale and the 12-item version of the World Health Organization disability assessment schedule were administered. Results: A total of 189 females (51.5%) and 178 (48.5%) males were studied. A lifetime prevalence of 12.3% was reported for anxiety disorder. Anxiety disorder was more likely in females (κ²=4.93, p<0.03). Specific prevalence for anxiety disorder in schizophrenia was generalized anxiety disorder 6.3%, obsessive compulsive disorder 3.3%, and phobic anxiety disorder 2.7%. Anxiety disorder was associated with increased disability (t=3.50, p<0.001) and psychopathology (t=3.40, p<0.001) among the participants studied. Phobias were associated with prescription of low doses of antipsychotics (κ²=4.08, p<0.04). There was a low rate of identification of anxiety disorder in routine clinical practice (k=0.08, p<0.001). Conclusion: Co-morbid anxiety disorders are common in schizophrenia and they are associated with increased disability and psychopathology. The results emphasize the need to screen for anxiety disorders in patients with schizophrenia.
