Background Childhood trauma has been significantly associated with first-episode psychosis, affective dysfunction and substance use. Aims To test whether people with first-episode psychosis who had experienced childhood trauma, when compared with those who had not, showed a higher rate of affective psychosis and an increased lifetime rate of substance use. Method The sample comprised 345 participants with first-episode psychosis (58% male, mean age 29.8 years, s.d. = 9.7). Results Severe sexual abuse was significantly associated with a diagnosis of affective psychosis (χ 2 = 4.9, P = 0.04) and with higher rates of lifetime use of cannabis (68% v 41%; P = 0.02) and heroin (20% v 5%; P = 0.02). Severe physical abuse was associated with increased lifetime use of heroin (15% v 5%; P = 0.03) and cocaine (32% v 17%; P = 0.05). Conclusions Patients with first-episode psychosis exposed to childhood trauma appear to constitute a distinctive subgroup in terms of diagnosis and lifetime substance use., Competing Interests: Declaration of interestNone., (© The Royal College of Psychiatrists 2017.)

Background The GET UP multi-element psychosocial intervention proved to be superior to treatment as usual in improving outcomes in patients with first-episode psychosis (FEP). However, to guide treatment decisions, information on which patients may benefit more from the intervention is warranted. Aims To identify patients' characteristics associated with (a) a better treatment response regardless of treatment type (non-specific predictors), and (b) a better response to the specific treatment provided (moderators). Method Some demographic and clinical variables were selected a priori as potential predictors/moderators of outcomes at 9 months. Outcomes were analysed in mixed-effects random regression models. (Trial registration: ClinicalTrials.gov, NCT01436331) Results Analyses were performed on 444 patients. Education, duration of untreated psychosis, premorbid adjustment and insight predicted outcomes regardless of treatment. Only age at first contact with the services proved to be a moderator of treatment outcome (patients aged ⩾35 years had greater improvement in psychopathology), thus suggesting that the intervention is beneficial to a broad array of patients with FEP. Conclusions Except for patients aged over 35 years, no specific subgroups benefit more from the multi-element psychosocial intervention, suggesting that this intervention should be recommended to all those with FEP seeking treatment in mental health services., Competing Interests: Declaration of interestNone., (© The Royal College of Psychiatrists 2017.)

Background: Considerable variations in the incidence of psychosis have been observed across countries, in terms of age, gender, immigration status, urbanicity and socioeconomic deprivation., Aims: To evaluate the incidence rate of first-episode psychosis in a large area of north-eastern Italy and the distribution of the above-mentioned risk factors in individuals with psychoses., Method: Epidemiologically based survey. Over a 3-year period individuals with psychosis on first contact with services were identified and diagnosed according to ICD-10 criteria., Results: In total, 558 individuals with first-episode psychosis were identified during 3,077,555 person-years at risk. The annual incidence rate per 100,000 was 18.1 for all psychoses, 14.3 for non-affective psychoses and 3.8 for affective psychoses. The rate for all psychoses was higher in young people aged 20-29 (incidence rate ratio (IRR) = 4.18, 95% CI 2.77-6.30), immigrants (IRR = 2.26, 95% CI 1.85-2.75) and those living in the most deprived areas (IRR = 2.09, 95% CI 1.54-2.85)., Conclusions: The incidence rate in our study area was lower than that found in other European and North American studies and provides new insights into the factors that may increase and/or decrease risk for developing psychosis., (Royal College of Psychiatrists.)
