ASSOCIATION OF CHILDHOOD TRAUMA AND PERSONALITY DIMENSIONS WITH THE DURATION OF UNTREATED PSYCHOSIS

Background: Understanding causes and consequences of untreated psychosis is important since the duration of psychosis prior to the treatment initiation is a potentially modifiable prognostic factor, and comprehending its impact on outcome may enhance therapeutic strategies. Subjects and methods: This cross-sectional study was performed on a consecutive sample of 105 participants, 47 first episode participants and 58 with multiple episodes. Primary outcome was the duration of untreated psychosis (DUP). We observed three independent variables: childhood trauma measured by Childhood Trauma Questionnaire, psychotic symptoms measured by Positive and Negative Syndrome Scale (PANSS) and personality dimensions measured by the Inventory of Personality Organization (IPO) (primitive defences, identity diffusion and reality testing). All outcomes were observed among total sample and subgroups of first and Results: Median DUP in total sample was 60.0 (IQR 14.5-285) days. In the subgroup of multiple episode participants, an association between multiple childhood trauma and shorter DUP was found, while no association between DUP and the existence of any specific trauma was found in neither subgroup, or in total sample. With regards to personality dimensions, in the first episode subgroup, significant positive correlations between DUP and primitive defences and reality testing subscales were found, while no correlations in total sample, nor in multiple episode subgroup were observed. Positive symptoms and general psychopathology correlated positively with DUP in total sample, and in first episode subgroup, while in multiple episodes subgroup only a positive correlation with positive symptoms was found. Total PANSS score positively correlated with the DUP only in the first episode subgroup. Conclusions: DUP was not associated with specific type of childhood trauma. First episode participants with longer DUP had predominant primitive defences and severely decreased ability to test reality, while there were no correlations between personality dimensions and DUP in multiple episode subgroup.
