Using the 2009 Swine Flu outbreak as a contemporary example of pandemic fears, this study examined the relationship between various symptoms related to anxiety sensitivity and Swine Flu fears. It was hypothesized that both obsessive–compulsive (OC) beliefs and OC symptoms would significantly predict Swine Flu fears. It was also hypothesized that symptoms of anxiety, including measures of anxiet...

Obsessive-compulsive (OC) symptoms during the course of schizophrenia have been reported, yet the incidence and significance of this finding is still unclear. This study was undertaken to determine the prevalence of OC symptoms among chronic schizophrenic patients and to systematically identify them. 101 patients satisfying DSM-IV diagnosis of chronic schizophrenia were assessed for OC symptoms...

Although obsessive-compulsive (OC) symptoms are observed along four dimensions (contamination, responsibility for harm, order/symmetry, and unacceptable thoughts), the structure of the dimensions remains unclear. The current study evaluated a bifactor model of OC symptoms among those with and without obsessive-compulsive disorder (OCD). The goals were (a) to evaluate if OC symptoms should be co...

The emergence or exacerbation of obsessive– compulsive (OC) symptoms during treatment with atypical antipsychotics, mostly clozapine, has been documented by numerous case reports (reviewed by Lykouras et al., 2003). In six recent reports involving nine cases, (Jonkers and deHaan, 2002; Lykouras et al., 2003) olanzapine was found either to cause de novo emergence or to exacerbate OC symptoms. In...

Oral contraceptives (OC) are very a widely prescribed therapy for premenstrual symptoms yet, only a limited number of studies have explored the relationship between OC and numerous premenstrual symptoms. The aim of this study was to investigate the differences in retrospectively reported premenstrual symptoms between users and non-users of oral contraceptives. In total 385 women (186 OC-users a...

OBJECTIVE To determine the contributions of genetic and environmental influences to variation in self-report of obsessive-compulsive (OC) symptoms in a population-based twin sample of adolescent boys and girls. METHOD Self-report ratings on the eight-item Youth Self-Report Obsessive-Compulsive Scale were collected in Dutch mono- and dizygotic twin pairs who participated at age 12 (N = 746 twi...

The goals of this work were to: (1) determine the prevalence of clinically significant obsessive-compulsive (OC) symptoms in patients with temporal lobe epilepsy (TLE), (2) characterize the differences in self-reported OC symptoms in patients with TLE and a normative control group, and (3) compare the severity of OC symptoms in right and left hemisphere TLE patients. Patients with TLE (n=30) we...
