Objectives: There is inconsistent evidence on the influence of ethnicity on duration of untreated psychosis (DUP). We investigated ethnic differences in DUP in a large epidemiological dataset of first episode psychosis patients in an inner city area of south London, UK., Methods: We analysed data on 558 first episode psychosis patients at the South London and Maudsley NHS Trust, between 2010 and 2012. We performed multivariable logistic regression to estimate the odds of a short DUP (≤ 6 months) by ethnic group, controlling for confounders., Results: There was no evidence that ethnicity is associated with duration of untreated psychosis. However, we found evidence that a short DUP was strongly associated with age, living circumstances, and pathways to care variables (involuntary admission, out of office hour contact, accident and emergency referral, criminal justice agency referral and family involvement in help-seeking). Conversely, a long DUP was associated with report of social isolation, living alone, being single and General Practitioner referral., Conclusion: Our findings suggest that indicators of social isolation were associated with long DUP. Our data also show that pathways into care characteristics play significant role in DUP. Thus, the challenge of tackling the issue of timely access to EI under the new Access and Waiting Time standard for psychosis requires a multilevel approach, including joint working with communities, public awareness of psychosis, less restrictive referral pathways and adequate resourcing of early intervention for psychosis services. These will go a long way in addressing patients' needs rather than be determined by service structures.

Background: A higher incidence of psychotic disorders has been consistently reported among black and other minority ethnic groups, particularly in northern Europe. It is unclear whether these rates have changed over time., Methods: We identified all individuals with a first episode psychosis who presented to adult mental health services between 1 May 2010 and 30 April 2012 and who were resident in London boroughs of Lambeth and Southwark. We estimated age-and-gender standardised incidence rates overall and by ethnic group, then compared our findings to those reported in the Aetiology and Ethnicity of Schizophrenia and Other Psychoses (ÆSOP) study that we carried out in the same catchment area around 10 years earlier., Results: From 9109 clinical records we identified 558 patients with first episode psychosis. Compared with ÆSOP, the overall incidence rates of psychotic disorder in southeast London have increased from 49.4 (95% confidence interval (CI) 43.6-55.3) to 63.1 (95% CI 57.3-69.0) per 100 000 person-years at risk. However, the overall incidence rate ratios (IRR) were reduced in some ethnic groups: for example, IRR (95% CI) for the black Caribbean group reduced from 6.7 (5.4-8.3) to 2.8 (2.1-3.6) and the 'mixed' group from 2.7 (1.8-4.2) to 1.4 (0.9-2.1). In the black African group, there was a negligible difference from 4.1 (3.2-5.3) to 3.5 (2.8-4.5)., Conclusions: We found that incidence rates of psychosis have increased over time, and the IRR varied by the ethnic group. Future studies are needed to investigate more changes over time and determinants of change.

Objectives: Compared with the majority population, those from minority ethnic groups in the UK are more likely to be admitted compulsorily during a first episode of psychosis (FEP). We investigated whether these disparities in pathways in to care continue., Methods: We analysed data from two first episode psychosis studies, conducted in the same geographical area in south London 15 years apart: the Aetiology and Ethnicity in Schizophrenia and Other Psychosis (AESOP) and the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) studies. The inclusion/exclusion criteria for case ascertainment for first episode psychosis were identical across the two studies. We performed multivariable logistic regression to estimate odds of compulsory admission by ethnic group, controlling for confounders., Participants: Two hundred sixty-six patients with first episode psychosis, aged 18-64 years, who presented to mental health services in south London in 1997-1999 and 446 with FEP who presented in 2010-2012., Results: When the two samples  were compared, ethnic differences in compulsory admission appear to have remained the same for black African patients, i.e. three times higher than white British in both samples: AESOP (adj. OR = 3.96; 95% CI = 1.80-8.71) vs. CRIS-FEP (adj. OR = 3.12; 95% CI = 1.52-6.35). Black Caribbean patients were three times more likely to be compulsorily admitted in AESOP (adj. OR = 3.20; 95% CI = 1.56-6.54). This was lower in the CRIS-FEP sample (adj. OR = 1.68; 95% CI = 0.71-3.98) and did not meet conventional levels for statistical significance., Conclusion: Ethnicity is strongly associated with compulsory admissions at first presentation for psychosis with evidence of heterogeneity across groups, which deserves further research.

Background: Psychological interventions which adopt an explicitly interpersonal approach are a recent development in the treatment of distressing voices. AVATAR therapy is one such approach which creates a direct dialogue between a voice-hearer and a computerised representation of their persecutory voice (the avatar) through which the person may be supported to gain a sense of greater power and control. The main objective of the trial is to test the clinical efficacy of this therapy to reduce the frequency and severity of auditory verbal hallucinations (AVH). Secondary objectives of the study are to explore explanatory mechanisms of action and potential moderators, to carry out a qualitative evaluation of participants' experience and to conduct an economic evaluation., Methods/design: The AVATAR randomised clinical trial will independently randomise 142 participants to receive either 7 sessions of AVATAR therapy or supportive counselling (SC). The study population will be individuals with schizophrenia spectrum and other psychotic disorders who report hearing persistent distressing voices, for more than 12 months, which are unresponsive or only partially responsive to antipsychotic medication. The main hypotheses are that, compared to SC, AVATAR therapy will reduce the frequency and severity of AVH and will also reduce the reported omnipotence and malevolence of these voices. Assessments will occur at 0 weeks (baseline), 12 weeks (post-intervention) and 24 weeks (follow-up), and will be carried out by blinded assessors. Both interventions will be delivered in a community-based mental health centre. Therapy competence and adherence will be monitored in both groups. Statistical analysis will follow the intention-to-treat principle and data will be analysed using a mixed (random) effects model at each post treatment time point separately. A formal mediation and moderator analysis using contemporary causal inference methods will be conducted as a secondary analysis. The trial is funded by the Welcome Trust (WT)., Discussion: AVATAR therapy showed promising effects in a pilot study, but the efficacy of the approach needs to be examined in a larger randomised clinical trial before wider dissemination and implementation in mental health services., Trial Registration: Current Controlled Trials, Isrctn: 65314790 , registration date: 27 March 2013.

Background: Self-poisoning (overdose) is the commonest form of self-harm cases presenting to acute secondary care services in the UK, where there has been limited investigation of self-harm in black and minority ethnic communities. London has the UK's most ethnically diverse areas but presents challenges in resident-based data collection due to the large number of hospitals., Aims: To investigate the rates and characteristics of self-poisoning presentations in two central London boroughs., Method: All incident cases of self-poisoning presentations of residents of Lambeth and Southwark were identified over a 12-month period through comprehensive acute and mental health trust data collection systems at multiple hospitals. Analysis was done using STATA 12.1., Results: A rate of 121.4/100,000 was recorded across a population of more than half a million residents. Women exceeded men in all measured ethnic groups. Black women presented 1.5 times more than white women. Gender ratios within ethnicities were marked. Among those aged younger than 24 years, black women were almost 7 times more likely to present than black men were., Conclusion: Self-poisoning is the commonest form of self-harm presentation to UK hospitals but population-based rates are rare. These results have implications for formulating and managing risk in clinical services for both minority ethnic women and men.

Background: Early specialised care may improve short-term outcome in first-episode non-affective psychosis, but it is unclear if these benefits endure., Aims: To assess the long-term effect of early intervention in psychosis., Method: Individuals with first-episode psychosis were randomised to specialised care or care as usual (trial number: ISRCTN73679874). Outcome after 5 years was assessed by case-note review., Results: There were no significant differences in the admission rate (coefficient 0.096, 95% CI -0.550 to 0.742, P = 0.770) or the mean number of bed days (coefficient 6.344, 95% CI -46 to 58.7, P = 0.810)., Conclusions: These findings that specialist intervention did not markedly improved outcome at 5 years accord with those from a larger OPUS study. The sample size of this study was small and these results should be generalised with caution. More research is needed.

Background: Childhood maltreatment among women is related to risk of adult depression and particularly an episode taking a chronic course. This paper explores the aspects of parental behaviour involved., Methods: An expanded version of CECA (Childhood Experiences of Care and Abuse), a retrospective interview-based instrument covering neglect as well as various forms of abuse is used to develop a new index of parental maltreatment. Data are derived from an enquiry of sister pairs between early 20s and 50s, comprising a high-risk series (n=118) where the first sister was selected as likely to have experienced childhood abuse or neglect, and a comparison series (n=80) where she was selected at random., Results: Adverse maternal behaviour emerges as of critical importance for the link with adult chronic depression. Maternal lack of affection ('neglect') and maternal rejection ('emotional abuse') form the core of an index of parental maltreatment, and it is concluded that persistent rejection, particularly from a mother, appears to be the core experience of importance. The findings of behavioural genetics that the experience of siblings of parents in ordinary families often differs have been found to hold for the more extreme behaviour involved in maltreatment. Difference between siblings in risk of later chronic depression is entirely related to such experience., Limitations: The study is based on retrospective questioning of adult women. Our next paper considers the possible threats to validity involved [Brown, G.W., Craig, T.K.J., Harris, T.O., Handley, R.V., Harvey, A.L., 2007a. Validity of retrospective measures of early maltreatment and depressive episodes using CECA (Childhood Experience of Care and Abuse) - a life-course study of adult chronic depression - 2. J. Affect. Disord. doi:10.1016/j.jad.2007.06.003]., Conclusions: Parental maltreatment emerges as a critical determinant of later chronic depressive episodes among adult women.

Background: An earlier paper [Brown, G.W., Craig, T.K.J., Harris, T.O., Handley, R.V., Harvey, A.L., 2007a-this issue. Development of a retrospective interview measure of parental maltreatment using the Childhood Experience of Care & Abuse (CECA) instrument - a life-course study of adult chronic depression - 1. J. Affect. Disord. doi:10.1016/j.jad.2007.05.022] documented an association between parental maltreatment and risk of adult chronic depression. This paper explores the contribution of other child-specific factors (e.g. conduct problems) and family-wide factors (e.g. parental discord)., Methods: Data are derived from an enquiry of 198 women largely comprising of adult sister pairs. Data was collected by semi-structured interviews covering a wide range of parental behaviour and childhood behaviour., Results: Parental maltreatment emerged as channelling the effect of family-wide factors on risk of adult chronic depression, but with a child's conduct problems and shame-withdrawal partly mediating this link. A child's depression before 17, although correlated with parental maltreatment, did not appear to play a significant role in adult depression. This core model is supplemented by analyses exploring the mechanisms involved. A mother's rejection/physical abuse and her depression via her lax control, for example, account for the link of parental maltreatment with conduct problems. Also 'rebelliousness' of a child relates to the chances of her low affection moving to rejection. "Rebelliousness" also appears to play a role in why the paired sisters so often had a different experience of maltreatment., Limitations: The data is collected retrospectively - but see [Brown, G.W., Craig, T.K.J., Harris, T.O., Handley, R.V., Harvey, A.L., 2007b-this issue. Validity of retrospective measures of early maltreatment and depressive episodes using the Childhood Experience of Care and Abuse (CECA) instrument - A life-course study of adult chronic depression - 2. J. Affect. Disord. doi:10.1016/j.jad.2007.06.003]., Conclusions: Child-specific factors play a major role in the origins of adult chronic depressive episodes. This, however, is fully consistent with an equally significant contribution from family-wide factors. The crucial point is that the link of the latter with such depression appears to be indirect and mediated very largely by parental maltreatment.

Background: Culture shock is a form of psychological distress associated with migration. Social support has been identified as significantly related to the onset, course and outcome of many psychological disorders., Aim: The aim of this study was to examine the relationship between culture shock and social support, in terms of size, diversity of the social network and quality of support received, in Greek students, in the UK., Method: A total of 133 students completed 3 self-administered questionnaires: Culture Shock Questionnaire, Social Support Questionnaire and General Health Questionnaire (GHQ-12)., Results: Gender and the quality of support received were found to be strongly associated with culture shock. Furthermore, culture shock was significantly positively related to the level of current dysphoria and diminished with time., Conclusion: Social support is an important factor associated with the degree of culture shock and should be taken into consideration in order to protect against or help to overcome this kind of psychological distress experienced by migrants.

Objective: To evaluate the effectiveness of a service for early psychosis., Design: Randomised controlled clinical trial., Setting: Community mental health teams in one London borough., Participants: 144 people aged 16-40 years presenting to mental health services for the first or second time with non-organic, non-affective psychosis., Interventions: Assertive outreach with evidence based biopsychosocial interventions (specialised care group) and standard care (control group) delivered by community mental health teams., Primary Outcome Measures: Rates of relapse and readmission to hospital., Results: Compared with patients in the standard care group, those in the specialised care group were less likely to relapse (odds ratio 0.46, 95% confidence interval 0.22 to 0.97), were readmitted fewer times (beta 0.39, 0.10 to 0.68), and were less likely to drop out of the study (odds ratio 0.35, 0.15 to 0.81). When rates were adjusted for sex, previous psychotic episode, and ethnicity, the difference in relapse was no longer significant (odds ratio 0.55, 0.24 to 1.26); only total number of readmissions (beta 0.36, 0.04 to 0.66) and dropout rates (beta 0.28, 0.12 to 0.73) remained significant., Conclusions: Limited evidence shows that a team delivering specialised care for patients with early psychosis is superior to standard care for maintaining contact with professionals and for reducing readmissions to hospital. No firm conclusions can, however, be drawn owing to the modest sample size.
