We selected women during their admission for delivery (n = 61) and analyzed: sociodemographically and through administration of EPDS, BDI, BAI, WHOQOL and SCID II (comparing Obsessive-Compulsive patients [OC=32] with negative patients [NEG=11]). Time of recruitment: 2 weeks

Labor: Emergency cesarian OC (21,4%) vn NEG (10,3%)

Previous treatment: OC (outpatient department+ private psychiatrist+ psychologist) 11,1% vs NEG 0%; only Psychologist OC 16,7% vs NEG 6,3%

Past drug intake: Antidepressant OC 11,1% vs NEG 0%

Miscarriage: OC (22,2%) vs NEG (31,3%)

Previous Oestroprogestinic intake : OC (66,7%) vs NEG (81,3%)

Complication during pregnancy: OC (38,9%) vs NEG (21,9%)

Whoqol psychological: OC (22,05) vs NEG (23,66) p = 0,46; environment: OC (28,32) vs NEG (31,09) p=0,015; physical: OC (23,37) vs NEG (26,72) p=0,011

BAI: OC (14,58) vs NEG (5,75) p=0,0005

BDI: OC (5,63) vs NEG (1,72) p< 0,0001

The groups clearly differ. From a test analysis we can underline that OC feels less confident in their environment and perceives less Physical wellness. BAI and BDI are statistically different, even if OC scores small level of anxiety or depression.
