The objective of this study will be to assess the impact of cannabis on the duration, the hospitalization and the short- and medium-term evolution of patients with psychotic symptoms and cannabis use. We hypothesize that these patients (in comparison with patients with psychotic symptomatology and not using cannabis) would be hospitalized more long, exposed to a higher risk of resistance to the usual therapeutics, would have a lack of therapeutic alliance and insight, relapses and hospitalizations more frequent, more marked negative symptoms and lower quality remission. They would also be more prone to impulsive and aggressive behaviour., conditionsModule conditions: Psychotic; Disorder, Cannabis, designModule studyType: OBSERVATIONAL, designInfo observationalModel: OTHER, timePerspective: PROSPECTIVE, enrollmentInfo count: 200, type: ESTIMATED, outcomesModule primaryOutcomes measure: PANSS: Positive and Negative Syndrom Scale, primaryOutcomes measure: PANSS: Positive and Negative Syndrom Scale, primaryOutcomes measure: PANSS: Positive and Negative Syndrom Scale, primaryOutcomes measure: PANSS: Positive and Negative Syndrom Scale, primaryOutcomes measure: MCQ-SF :Marijuana Craving Questionnaire- Short Form, primaryOutcomes measure: MCQ-SF :Marijuana Craving Questionnaire- Short Form), primaryOutcomes measure: MCQ-SF :Marijuana Craving Questionnaire- Short Form), primaryOutcomes measure: MCQ-SF :Marijuana Craving Questionnaire- Short Form), primaryOutcomes measure: CGI: Clinical Global Impression, primaryOutcomes measure: CGI: Clinical Global Impression, primaryOutcomes measure: CGI: Clinical Global Impression, primaryOutcomes measure: CGI: Clinical Global Impression, primaryOutcomes measure: MADRS: Montgomery Åsberg Depression Rating Scale, primaryOutcomes measure: MADRS: Montgomery Åsberg Depression Rating Scale, primaryOutcomes measure: MADRS: Montgomery Åsberg Depression Rating Scale, primaryOutcomes measure: MADRS: Montgomery Åsberg Depression Rating Scale, primaryOutcomes measure: PDS: Psychotic Depression Scale, primaryOutcomes measure: PDS: Psychotic Depression Scale, primaryOutcomes measure: PDS: Psychotic Depression Scale, primaryOutcomes measure: PDS: Psychotic Depression Scale, primaryOutcomes measure: YMRS: Young Mania Rating Scale, primaryOutcomes measure: YMRS: Young Mania Rating Scale, primaryOutcomes measure: YMRS: Young Mania Rating Scale, primaryOutcomes measure: YMRS: Young Mania Rating Scale, primaryOutcomes measure: CDS: Self-Consciousness Revised Scale, primaryOutcomes measure: CTQ: Childhood Trauma Questionnaire, primaryOutcomes measure: BFI: Big Five Inventory, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: unité de recherche clinique de l'E.P.S de Ville Evrard, status: RECRUITING, city: Neuilly Sur Marne, zip: 93332, country: France, contacts name: Rusheenthira THAVASEELAN, Msc, role: CONTACT, phone: 0143093232, email: r.thavaseelan@epsve.fr, geoPoint lat: 48.85373, lon: 2.54903, hasResults: False
