Purpose: Although many women experience obsessive-compulsive symptoms during the perinatal period, the Yale-Brown Obsessive Compulsive Scale (YBOCS) has not yet been psychometrically evaluated in this population. This study examined the internal consistency, convergent and divergent validity, and factor structure of the YBOCS among pregnant women.
Methods: 256 Women who were 20 to 24 weeks pregnant completed the clinician-administered YBOCS and Mini International Neuropsychiatric Interview (MINI) along with a series of self-report questionnaires including the Edinburgh Postnatal Depression Scale (EPDS), Perinatal Anxiety Screening Scale (PASS) and Obsessive-Compulsive Inventory-Revised (OCI-R).
Article Synopsis
- * A total of 205 patients participated, with a 1-year target-vessel failure (TVF) rate of 7.4%, significantly below the performance goal set at 24.5%, and a 3-year TVF rate of 12.1%.
- * The findings indicate that using a provisional stenting approach for bifurcation lesions with the Resolute Onyx ZES led to positive clinical outcomes, suggesting it
Article Synopsis
- Obsessive-compulsive disorder (OCD) affects about 1% of people and has a strong genetic component, but previous studies have not fully explained its genetic causes or biological mechanisms.
- A large genome-wide association study (GWAS) analyzed data from over 53,000 OCD cases and over 2 million control participants, identifying 30 significant genetic markers related to OCD and suggesting a 6.7% heritability from SNPs.
- The research also found 249 candidate risk genes linked to OCD, particularly in specific brain regions, and showed genetic correlations with various psychiatric disorders, laying the groundwork for further studies and potential treatments.
The experience of doubt, the lack of confidence in one's perceptions, internal states, memory and attention, can be due to the variability in occurrence of a phenomenon or can be driven by the internal experience of uncertainty based on subjective evaluation of the environment. Although the experience of some doubt is adaptive in normal cognitive functioning, excessive doubt can significantly impair decision-making and in extreme cases give rise to psychopathology. Although neuroimaging studies have provided some insight into the network of brain areas that is engaged when decision-making involves uncertainty, it remains unclear if dysfunction in these areas also gives rise to the experience and pathological expression of doubt.
