Eventi di vita stressanti in un campione di pazienti affetti da psicosi all’esordio: prevalenza, sintomatologia ed età d’esordio
2011
Introduzione: Un consistente numero di studi suggerisce un’elevata prevalenza di eventi traumatici nella storia di soggetti con disturbi psicotici (Shevlin et al, 2008). Piu’ che l’impatto di un singolo evento di vita stressante, l’esposizione cumulativa ad esperienze traumatiche sembra incrementare il rischio di psicosi (van Winkel et al, 2008). Scopo dello studio e’ valutare la prevalenza di tali eventi in soggetti al primo episodio psicotico a confronto con controlli sani e la possibile correlazione con la sintomatologia psicotica e l’età di esordio. Metodologia: In atto sono stati reclutati 74 soggetti al primo episodio psicotico (51 m, 23 f; em=26.39, ds=9.36) e 27 controlli sani (18 m…
O3.1. ASSOCIATION OF EXTENT OF CANNABIS USE AND ACUTE INTOXICATION EXPERIENCES IN A MULTI-NATIONAL SAMPLE OF FIRST EPISODE PSYCHOSIS PATIENTS AND CON…
2019
Background FEP patients who use cannabis experience more frequent intoxication experiences compared to controls. It is not clear whether this is consequent to patients being more vulnerable to the effects of cannabis use or to their heavier pattern of use. We aimed to determine whether extent of use predicted psychotic-like and euphoric intoxication experiences in FEP patients and controls and whether this differs between groups. Methods We analysed data on lifetime cannabis using patients (n=655) and controls (n=654) across 15 sites from six countries in the EU-GEI study (2010–2015). We used multiple regression to model predictors of cannabis-induced experiences and Factorial ANOVA to dete…

ADDITIVE INTERACTION BETWEEN LIFETIME CANNABIS USE AND CHILDHOOD TRAUMA IN INCREASING THE RISK FOR PSYCHOSIS. A REPLICATION ANALYSIS ON A SAMPLE OF F…
2012
Background: Additive interaction between childhood trauma and cannabis use in increasing risk for psychotic disorders has been recently demonstrated in a prospective (Harley et al., 2009) and a cross sectional study (Konigs et al., 2011), although not replicated in another survey (Kuepper et al., 2011). This study aimed to analyse additive interaction between lifetime cannabis and severe child abuse in increasing the risk for psychosis in a sample of first episode psychosis patients and geographically matched controls. In addition, analyses were re-run separately for males and females in order to investigate whether the association was moderated by gender. Methods: The sample consisted of 2…

La muestra estaba compuesta por 1378 sujetos, con edades comprendidas entre los 13 y los 19 años. El análisis se realizó a través del Modelo de Regresión de Poisson.

Mediating Effects of Global Negative Effect Expectancies on the Association between Problematic Cannabis Use and Social Anxiety
2017
The relationship between social anxiety and cannabis use among adolescents and young adults is a highly debated topic. In this cross-sectional study, we tested whether cannabis use expectancies mediated the association between social anxiety and cannabis use severity in a sample of 343 young adults (74.3% male) who used cannabis. They completed self-report measures for the screening of problematic cannabis use (Cannabis Use Problems Identification Test) and social anxiety symptoms (Social Interaction Anxiety Scale and Social Phobia Scale). A multiple mediation analysis was used to test whether marijuana effect expectancies mediate social anxiety effect on problematic cannabis use. Social an…
