Predictors of Readmission in Young Adults with First-Episode Psychosis: A Multicentric Retrospective Study with a 12-Month Follow-Up. Clin Pract 2024; 14:1234-1244. [PMID: 39051293 PMCID: PMC11270315 DOI: 10.3390/clinpract14040099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 06/10/2024] [Accepted: 06/18/2024] [Indexed: 07/27/2024] Open
Abstract
BACKGROUND A significant number of young individuals are readmitted one or more times shortly after their first episode of psychosis. Readmission may represent a marker of psychopathological vulnerability. Our primary aim was to evaluate the impact of clinical and socio-demographic variables on readmission at 12-month follow-up. Secondly, our goal was to determine whether the use of Long-Acting Injection (LAI) antipsychotics provides notable benefits compared to oral medications in preventing subsequent readmissions. SUBJECTS AND METHODS 80 patients hospitalised for the first time with a diagnosis of psychotic disorder (ICD-10 criteria) were retrospectively assessed through clinical records. The mean age was 21.7 years. Patients were predominantly male (n = 62, 77.5%), and 55 subjects had at least 8 years of education. 50% of the sample was "NEET" (not in education, employment, or training). RESULTS 35 patients (43.8%) were discharged with a LAI antipsychotic, while 45 (56.2%) recieved oral antipsychotic therapy. Substance use (p = 0.04) and oral antipsychotics at discharge (p = 0.003) were significantly associated with readmission at 1 year. We did not find any significant predictors of being discharged with LAI therapy. CONCLUSION Our findings underlined the importance of identifying patients at risk of readmission in order to prevent future rehospitalization and promote appropriate prevention strategies. LAIs should be considered as a first-choice treatment for patients hospitalised for FEP since they proved to be effective in preventing relapse.

Abstract
BACKGROUND Substance use remains a barrier to recovery for young people accessing early intervention services for psychosis. While correlates of use have been explored in populations experiencing a first episode of psychosis (FEP), sample sizes have been small and less research assesses cohorts at ultrahigh risk of psychosis (UHR). METHODS This study uses data from a naturalistic cohort including UHR and FEP participants (N = 1252) to elucidate clinical correlates of use in the past 3 months of any illicit substance, amphetamine-type stimulants (ATS), cannabis, and tobacco. Moreover, network analysis based on use of these substances and additionally alcohol, cocaine, hallucinogens, sedatives, inhalants, and opioids was completed. RESULTS Young people with FEP used substances at significantly higher rates than those at UHR. High concurrence of use was seen between substances. In the FEP group, participants who had used any illicit substance, ATS, and/or tobacco had increased positive symptoms and decreased negative symptoms. Young people with FEP who used cannabis had increased positive symptoms. In the UHR group, participants who had used any illicit substance, ATS, and/or cannabis in the past 3 months showed decreased negative symptoms compared to those who had not. CONCLUSION A distinct clinical picture of more florid positive symptoms and alleviated negative symptoms seen in those who use substances in the FEP group appears muted in the UHR cohort. Treating young people at UHR in early intervention services represents the earliest opportunity to address substance use early to improve outcomes.

Abstract
Clozapine (CLZ) is an atypical antipsychotic reserved for patients with refractory psychosis, but it is associated with a significant risk of severe adverse reactions (ADRs) that are potentiated with the concomitant use of alcohol. Additionally, pharmacogenetic studies have explored the influence of several genetic variants in CYP450, receptors and transporters involved in the interindividual response to CLZ. Herein, we systematically review the current multiomics knowledge behind the interaction between CLZ and alcohol intake, and how its concomitant use might modulate the pharmacogenetics. CYP1A2*1F, *1C and other alleles not yet discovered could support a precision medicine approach for better therapeutic effects and fewer CLZ ADRs. CLZ monitoring systems should be amended and include alcohol intake to protect patients from severe CLZ ADRs.

Abstract
Introduction: Research has established a link between cannabis use and adverse psychotic outcomes in psychosis patients. However, we have yet to determine if this relationship is maintained when controlling for important confounding variables. The following systematic review aims to investigate if the association between cannabis use and psychotic outcomes is preserved when accounting for important confounders, and if discontinued use mitigates any potential negative impacts.Areas covered: The authors conducted an exhaustive search of the MEDLINE database and Google Scholar to identify articles pertaining to the systematic review. Thirty-three articles were retained for meeting the eligibility criteria.Expert opinion: The evidence confirms an overarching pattern of negative psychotic outcomes of cannabis intake in psychosis populations, even when accounting for crucial confounders. Psychosis patients should be informed with evidence-based health information regarding the effects of cannabis use. Clinicians should systematically evaluate cannabis intake patterns in psychosis patients and offer intervention services geared toward reducing problematic consumption. Researchers should record confounding factors in a more systematic manner in future longitudinal investigations while paying careful attention to the potency and dose-response effects of the ingested cannabis. Deciders will need to investigate the impact of cannabis regulations on psychosis populations.

Abstract
OBJECTIVE To determine whether gender differences in symptom presentation at first episode psychosis (FEP) remain even when controlling for substance use, age and ethnicity, using natural language processing applied to electronic health records (EHRs). DESIGN, SETTING AND PARTICIPANTS Data were extracted from EHRs of 3350 people (62% male patients) who had presented to the South London and Maudsley NHS Trust with a FEP between 1 April 2007 and 31 March 2017. Logistic regression was used to examine gender differences in the presentation of positive, negative, depressive, mania and disorganisation symptoms. EXPOSURES FOR OBSERVATIONAL STUDIES Gender (male vs female). MAIN OUTCOMES AND MEASURES Presence of positive, negative, depressive, mania and disorganisation symptoms at initial clinical presentation. RESULTS Eight symptoms were significantly more prevalent in men (poverty of thought, negative symptoms, social withdrawal, poverty of speech, aggression, grandiosity, paranoia and agitation). Conversely, tearfulness, low energy, reduced appetite, low mood, pressured speech, mood instability, flight of ideas, guilt, mutism, insomnia, poor concentration, tangentiality and elation were more prevalent in women than men. Negative symptoms were more common among men (OR 1.85, 95% CI 1.33 to 2.62) and depressive and manic symptoms more common among women (OR 0.30, 95% CI 0.26 to 0.35). After adjustment for illicit substance use, the strength of associations between gender and negative, manic and depression symptoms increased, whereas gender differences in aggression, agitation, paranoia and grandiosity became insignificant. CONCLUSIONS There are clear gender differences in the clinical presentation of FEP. Our findings suggest that gender can have a substantial influence on the nature of clinical presentation in people with psychosis, and that this is only partly explained by exposure to illicit substance use.

Abstract
OBJECTIVE Alcohol and cannabis misuse are common in patients with early phase psychosis (EPP); however, research has tended to focus primarily on cannabis misuse and EPP outcomes, with a relative lack of data on alcohol misuse. This retrospective cross-sectional EPP study investigated the relationship between cannabis, alcohol, and cannabis combined with alcohol misuse, on age, gender, psychotic, depressive and anxiety symptom severity, and social/occupational functioning, at entry to service. METHODS Two-hundred and sixty-four EPP patients were divided into 4 groups based on substance use measured by the Alcohol, Smoking and Substance Involvement Screening Test: (1) no to low-level cannabis and alcohol misuse (LU), (2) moderate to high alcohol misuse only (AU), (3) moderate to high cannabis misuse only (CU), and (4) moderate to high alcohol and cannabis misuse (AU + CU). RESULTS We found significant between group differences in age (with the AU group being the oldest and AU + CU group the youngest) as well as gender (with the CU group having the highest percentage of men). There were also group differences in positive psychotic symptoms (lowest in AU group), trait anxiety (highest in AU + CU group), and social/occupational functioning (highest in AU group). Further regression analyses revealed a particularly strong relationship between AU + CU group and trait anxiety (3-fold increased odds of clinical trait anxiety for combined misuse of alcohol and cannabis compared to non/low users). CONCLUSIONS This study demonstrates the unique demographic and clinical characteristics found in the EPP population at entry to care associated with alcohol and cannabis misuse both separately and in combination. This work highlights the importance of including the assessment of alcohol misuse in addition to cannabis misuse in future treatment guidelines and research.

Abstract
Background Use of psychoactive substances is a common finding in studies on first-episode psychosis (FEP), and this has prognostic implications. We know very little about psychoactive substance use (SU) among patients with FEP in the Eastern Cape province (EC) of South Africa (SA). Aim The study seeks to determine SU prevalence and associated features among inpatients with non-affective FEP in an acute mental health unit (MHU) in Nelson Mandela Bay, EC. Setting Researchers conducted a retrospective clinical file review of a 12-month admission cohort of patients with FEP, without a concurrent mood episode, to the Dora Nginza Hospital MHU. Information collected included SU history, psychiatric diagnoses, and demographics. Data were then subjected to statistical analysis. Methods Researchers conducted a retrospective clinical file review of a 12-month admission cohort of patients with FEP, without a concurrent mood episode, to the Dora Nginza Hospital MHU. Information collected included SU history, psychiatric diagnoses and demographics. Data were then subjected to statistical analysis. Results A total of 117 patients (86 [73.5%] males; 31 [26.5%] females) aged 18–60 years (mean 29 years) met the inclusion criteria. After controlling for missing information, 95 of 117 (81.2%) patients had a history of active or previous SU, 82 of 90 (91.1%) were single and 61 of 92 (66.3%) were unemployed. A significant association was found between SU and unemployment (p < 0.001), as well as male sex (p < 0.001). The most common substances used were cannabis (59.8%), followed by alcohol (57.3%) and stimulants (46.4%). Conclusion In keeping with national and international literature, the results of this study showed a high prevalence of substance use in South African patients with first-episode psychosis. The high prevalence of lifetime substance use in this cohort compared to previous studies in South Africa requires further investigation and highlights the urgent need for dual diagnosis services in the Eastern Cape province.

Abstract
AIM The primary aim of this study was to examine the effect of recent tobacco, alcohol and cannabis use on treatment outcomes among participants experiencing first episode psychosis (FEP). METHODS Secondary data analyses were conducted on 404 participants enrolled in the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study. RAISE-ETP investigated the effectiveness of a coordinated specialty care (CSC) intervention for FEP in community mental health agencies in the United States. Generalized estimating equations were used to examine whether recent tobacco smoking, alcohol, and cannabis use at baseline were associated with illness severity, number of antipsychotic pills missed, psychiatric symptoms and quality of life during the 24-month treatment period, after controlling for duration of untreated psychosis and treatment group. RESULTS At baseline, roughly 50% (n = 209) of participants reported recent tobacco, 28% (n = 113) alcohol and 24% (n = 95) cannabis use. Tobacco smokers had higher levels of illness severity (β = .24; P < .005), a higher number of missed pills (β = 2.89; P < .05), higher psychiatric symptoms and lower quality of life during treatment relative to non-smokers. Alcohol users had a higher number of missed pills (β = 3.16; P < .05) during treatment and cannabis users had higher levels of illness severity (β = .18; P < .05) and positive symptoms (β = 1.56; P < .05) relative to non-users. CONCLUSIONS Tobacco, alcohol and cannabis use are common in youth seeking treatment for FEP. Tobacco smoking was associated with more negative clinical outcomes. These findings have implications for including interventions targeting these areas of substance use within current CSC models.

Abstract
Lifetime co-occurring substance use disorders are common at the time of presentation for treatment of a first episode of primary psychosis and persistent substance use disorder (SUD) leads to poorer outcomes. We assessed whether the NAVIGATE program, a coordinated specialty care service that includes optional substance abuse content reduced substance use compared to usual care in 404 individuals in the Recovery After Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study. Participants were randomized to two years of NAVIGATE (n = 223) or usual care (n = 181) and assessed monthly for substance use. At baseline, over one-half (51.7%) of the participants met criteria for a lifetime SUD, including over one-third with alcohol use disorder (36.4%) and with cannabis use disorder (34.7%). Contrary to our hypothesis, there was no treatment group by time interaction effect on days of self-reported substance use over the two-year follow-up. Participant exposure to the substance abuse component of the NAVIGATE program was low, suggesting that modifications to the program and training method for clinicians may be needed. Further research is needed to determine the most effective strategies for addressing substance use disorders in persons recovering from a first episode of psychosis.

Abstract
BACKGROUND We assessed the prevalence and correlates of lifetime substance use disorders in people with first episode psychosis using the baseline data from the Recovery After an Initial Schizophrenia Episode (RAISE) Early Treatment Program study. METHODS Research staff assessed 404 first episode patients at 34 community mental health centers across the United States with the Structured Clinical Interview for DSM-IV for diagnoses of psychotic and substance use disorders. Logistic regression was used to evaluate the relationships between participant characteristics and lifetime substance use disorders, followed with generalized linear mixed-effects regression models to identify unique predictors of lifetime substance use disorders. RESULTS Approximately one-third of participants reported recent alcohol use (36.6%) and cannabis use (30.7%), and one half (51.7%) met criteria for any lifetime alcohol or drug use disorder. Lifetime substance use disorders were associated with male gender, White race, higher excited (hyperactivity, mood lability, impulsivity, hostility, and uncooperativeness), psychotic and depressive symptoms, less impaired cognition, and greater perceived stigma. Gender, race, and excited symptoms were the most consistent unique predictors of lifetime substance use disorders found in multivariate analyses. CONCLUSIONS Half of first episode psychosis patients have co-occurring substance use disorders, which are associated with both more severe symptoms and greater perceptions of stigma. Programs aiming to serve these patients must have the skills and clinical strategies to help people with these unique characteristics.

Abstract
Cannabis use is more common among people with severe mental illness than in the general population. It has detrimental effects on the course of the illness, physical health and social life of users, as well as being a financial burden on health services. It is important to understand why some people with severe mental illness continue to use cannabis, despite experiencing its effects on their condition. This article reviews research on the scale of cannabis use by such patients, the effects on the course of their illness, possible reasons to explain why they use it, and how they can be assessed in clinical settings, as well as providing some assessment tools to measure various characteristics related to cannabis use.

Abstract
BACKGROUND Many studies have concluded that cannabis use disorder (CUD) negatively influences outcomes in first-episode psychosis (FEP). However, few have taken into account the impact of concurrent misuse of other substances. METHODS This 2-year, prospective, longitudinal study of FEP patients, aged between 18 and 30 years, admitted to early intervention programs in Montreal, Quebec, Canada, examined the specific influence of different substance use disorders (SUD) (alcohol, cannabis, cocaine, amphetamines) on service utilization, symptomatic and functional outcomes in FEP. RESULTS Drugs and alcohol were associated with lower functioning, but drugs had a greater negative impact on most measures at 2-year follow-up. Half of CUD patients and more than 65% of cocaine or amphetamine abusers presented polysubstance use disorder (poly-SUD). The only group that deteriorated from years 1 to 2 (symptoms and functioning) were patients with persistent CUD alone. Outcome was worse in CUD than in the no-SUD group at 2 years. Cocaine, amphetamines and poly-SUD were associated with worse symptomatic and functional outcomes from the 1st year of treatment, persisting over time with higher service utilization (hospitalization). CONCLUSION The negative impact attributed to CUD in previous studies could be partly attributed to methodological flaws, like including polysubstance abusers among cannabis misusers. However, our investigation confirmed the negative effect of CUD on outcome. Attention should be paid to persistent cannabis misusers, since their condition seems to worsen over time, and to cocaine and amphetamine misusers, in view of their poorer outcome early during follow-up and high service utilization.

Abstract
Substance use is common in first-episode psychosis (FEP) and has been linked to poorer outcomes with more severe psychopathology and higher relapse rates. Early substance discontinuation appears to improve symptoms and function. However, studies vary widely in their methodology, and few have examined patients longitudinally, making it difficult to draw conclusions for practice and treatment. We aimed to investigate the relationship between substance use and early abstinence and the long-term course of illness in a representative sample of FEP patients. Out of 301 included patients, 266 could be divided into 4 groups based on substance use patterns during the first 2 years of treatment: persistent users, episodic users, stop-users and nonusers. Differences in clinical and functional measures during the follow-up period were assessed using linear mixed effects models for the analysis of repeated measures data. Patients who stopped using substances within the first 2 years after diagnosis had outcomes similar to those who had never used with fewer symptoms than episodic or persistent users. Both episodic and persistent users had lower rates of symptom remission than nonusers, and persistent users also had more negative symptoms than those who stopped using. Our findings emerge from one of very few long-term longitudinal studies examining substance use cessation in FEP with 10-year follow-up. The results convey hope that the detrimental effects of substance abuse on mental health may be significantly reversed if one stops the abuse in time. This can help patients who struggle with addiction with their motivation to embrace abstinence.

Abstract
Substance use disorders (SUD) in first-episode psychosis (FEP) are highly prevalent and linked with poor outcomes. However, most longitudinal studies investigating their impacts in FEP have not reported proportions of patients who ceased SUD. Our aim was to examine the influence of SUD course on functional and symptomatic outcomes as well as service use in FEP. We performed a 2-year longitudinal study of 212 FEP patients, aged between 18 and 30 years, admitted to 2 early psychosis services in Montréal, Québec, Canada. We observed that cannabis was the first substance abused (42.9% at baseline), followed by alcohol (19.3%). The SUD rate decreased by approximately 30% during the first year. Patients with persistent SUD had worse functional outcomes (Quality of Life Scale, Social and Occupational Functioning Assessment Scale, employment), more symptoms (Positive and Negative Symptoms Scale) and heavier service use (emergency and hospitalization). SUD persistence was associated with illness severity, homelessness and cluster-B personality. Those living with their parents and financially supported by them were more likely to cease SUD. Our results indicate that SUD course was more significant than having SUD at admission; persistent SUD was associated with worse outcomes. SUD decreased during a general early psychosis intervention program (with no specialized SUD treatment). An integrated, specialized approach targeting FEP patients with predictive factors of SUD persistence during the first years of treatment might increase SUD cessation and possibly improve outcomes.

Abstract
BACKGROUND This paper examines the role of therapeutic alliance in predicting outcomes in a Randomized Controlled Trial of Motivational Interviewing and Cognitive Behavioral Therapy (MICBT) for problematic cannabis use in recent onset psychosis. METHODS All clients were participating in a three arm pragmatic rater-blind randomized controlled trial of brief MICBT plus standard care compared with longer term MICBT plus standard care and standard care alone. Participants completed measures to assess clinical symptoms, global functioning and substance misuse at baseline, 4.5months, 9months and 18months. Clients and therapists completed the Working Alliance Inventory approximately one month into therapy. Client alliance data was available for 35 participants randomized to therapy and therapist alliance data was available for 52 participants randomized to therapy. RESULTS At baseline, poorer client-rated alliance was associated with more negative symptoms, poorer insight and greater cannabis use, whereas poorer therapist-rated alliance was only associated with amount of cannabis used per cannabis using day. Alliance ratings were also positively associated with amount of therapy: client-rated alliance was higher in the longer compared to the briefer therapy; therapist-rated alliance was associated with greater number of sessions attended (controlling for type of therapy) and therapy completion. In predicting outcome, client-rated alliance predicted total symptom scores and global functioning scores at follow-up. Neither client nor therapist alliance predicted changes in substance misuse at any time point. CONCLUSIONS Findings demonstrate that individuals with psychosis and substance misuse who form better alliances with their therapists gain greater benefits from therapy, at least in terms of improvements in global functioning.

Continued versus discontinued cannabis use in patients with psychosis: a systematic review and meta-analysis. Lancet Psychiatry 2016; 3:215-25.

Abstract
BACKGROUND Although the link between cannabis use and development of psychosis is well established, less is known about the effect of continued versus discontinued cannabis use after the onset of psychosis. We aimed to summarise available evidence focusing on the relationship between continued and discontinued cannabis use after onset of psychosis and its relapse. METHODS In this systematic review and meta-analysis, we searched MEDLINE for articles published in any language from the database inception date up until April 21, 2015 that included a sample of patients with a pre-existing psychotic disorder with a follow-up duration of at least 6 months. We used a combination of search terms for describing cannabis, the outcome of interest (relapse of psychosis), and the study population. We excluded studies if continued cannabis use or discontinued cannabis use could not be established. We compared relapse outcomes between those who continued (CC) or discontinued (DC) cannabis use or were non-users (NC). We used summary data (individual patient data were not sought out) to estimate Cohen's d, which was entered into random effects models (REM) to compare CC with NC, CC with DC, and DC with NC. Meta-regression and sensitivity analyses were used to address the issue of heterogeneity. FINDINGS Of 1903 citations identified, 24 studies (16 565 participants) met the inclusion criteria. Independent of the stage of illness, continued cannabis users had a greater increase in relapse of psychosis than did both non-users (dCC-NC=0·36, 95% CI 0·22-0·50, p<0·0001) and discontinued users (dCC-DC=0·28, 0·12-0·44, p=0·0005), as well as longer hospital admissions than non-users (dCC-NC=0·36, 0·13 to 0·58, p=0·02). By contrast, cannabis discontinuation was not associated with relapse (dDC-NC=0·02, -0·12 to 0·15; p=0·82). Meta-regression suggested greater effects of continued cannabis use than discontinued use on relapse (dCC-NC=0·36 vs dDC-NC=0·02, p=0·04), positive symptoms (dCC-NC=0·15 vs dDC-NC=-0·30, p=0·05) and level of functioning (dCC-NC=0·04 vs dDC-NC=-0·49, p=0·008) but not on negative symptoms (dCC-NC=-0·09 vs dDC-NC=-0·31, p=0·41). INTERPRETATION Continued cannabis use after onset of psychosis predicts adverse outcome, including higher relapse rates, longer hospital admissions, and more severe positive symptoms than for individuals who discontinue cannabis use and those who are non-users. These findings point to reductions in cannabis use as a crucial interventional target to improve outcome in patients with psychosis. FUNDING UK National Institute of Health Research.

Abstract
Co-occurring substance use in psychotic patients causes many subsequences including increased illness severity, decreased medication compliance, higher relapse rates, more hospitalizations, and legal problems. We aim to investigate the prevalence, patterns, associated factors and severity of substance use risk among psychotic patients in southern Thailand. Psychotic out-patients were screened with the Alcohol, Smoking, Substance Involvement Screening Test (ASSIST) for their history of substance use in the past three months and categorized as None-to-Low Risk (NLR) or Moderate-to-High Risk (MHR) levels. Multivariate logistic regression was used to examine the associated factors of substance use risk-level. The associations between substance use risk-level and emotional and behavioural symptoms, functional status and family functional status were examined using multivariate linear regression analysis. Of 663 participants screened, 322 (48.6%) used at least one substance in the past three months. Tobacco was the most common substance used (47.2%). The factors associated with a higher risk of any substance use were male gender, young age group, low level of education, being employed and being diagnosed with schizophrenia. A higher number of emotional and behavioural symptoms was significantly associated with higher substance use risk-level. In conclusion, the prevalence of substance use in psychotic patients was high and associated with their emotional and behavioural symptoms. Recommendations for implementation of screening and early intervention programs of substance-related problems in psychotic patients are important for preventing unwanted outcomes.

Abstract
OBJECTIVE Only a few studies in patients with first-episode psychosis have included gender in the study hypothesis or considered this a primary study variable. The aim of this study was to explore the influence of gender in the pattern of substance use in patients with first-episode psychosis. METHODS This is a sub-analysis of a randomized open clinical trial that compared 1-year treatment retention rates of patients with first-episode psychosis randomized to haloperidol, olanzapine, quetiapine, risperidone, or ziprasidone. Our sub-analysis included 85 men and 29 women. RESULTS Substance use was relatively high among these patients and differed significantly by gender. Men were more likely to use substances overall than women (89.4% for men vs. 55.2% for women), χ(2) = 16.2, df = 1, p <.001, and were also more likely to use alcohol (χ(2) = 13, df = 1, p <.001), cannabis (χ(2) = 9.9; df = 1, p <.002), and cocaine (χ(2) = 10.3; df = 1, p <.001), compared to women. While there were no gender differences in age at first consumption of alcohol or cocaine, men were significantly younger at first consumption of cannabis (M = 16.08 years, SD = 2.1) than women (M = 18.0 years, SD = 3.8), F(1, 59) = 5, p <.02. When analyzed separately by gender, women showed no significant differences in the influence of number of substances used on age at onset of psychosis, F(3, 29) = 1.2, p =.30. However, there was a significant difference among men, with earlier onset of psychosis noted in men consuming multiple substances; F(4, 85) = 5.8, p <.0001. Regarding prediction of age at onset of psychosis, both male gender and the use of a higher number of substances significantly predicted an earlier age at onset of psychosis. CONCLUSIONS Our study provides some evidence of gender differences in the pattern of substance use in patients with first-episode psychosis, suggesting the possible need for gender-specific approaches in the interventions performed in these patients. This study is registered as #12610000954022 with the Australian New Zealand Clinical Trials Registry (www.anzctr.org.au).

Abstract
BACKGROUND Why patients with psychosis use cannabis remains debated. The self-medication hypothesis has received some support but other evidence points towards an alleviation of dysphoria model. This study investigated the reasons for cannabis use in first-episode psychosis (FEP) and whether strength in their endorsement changed over time. METHODS FEP inpatients and outpatients at the South London and Maudsley, Oxleas and Sussex NHS Trusts UK, who used cannabis, rated their motives at baseline (n=69), 3 months (n=29) and 12 months (n=36). A random intercept model was used to test the change in strength of endorsement over the 12 months. Paired-sample t-tests assessed the differences in mean scores between the five subscales on the Reasons for Use Scale (enhancement, social motive, coping with unpleasant affect, conformity and acceptance and relief of positive symptoms and side effects), at each time-point. RESULTS Time had a significant effect on scores when controlling for reason; average scores on each subscale were higher at baseline than at 3 months and 12 months. At each time-point, patients endorsed 'enhancement' followed by 'coping with unpleasant affect' and 'social motive' more highly for their cannabis use than any other reason. 'Conformity and acceptance' followed closely. 'Relief of positive symptoms and side effects' was the least endorsed motive. CONCLUSIONS Patients endorsed their reasons for use at 3 months and 12 months less strongly than at baseline. Little support for the self-medication or alleviation of dysphoria models was found. Rather, patients rated 'enhancement' most highly for their cannabis use.

Effects of a brief intervention for substance use on tobacco smoking and family relationship functioning in schizophrenia and related psychoses: a randomised controlled trial. J Subst Abuse Treat 2014; 51:30-7. [PMID: 25468004 DOI: 10.1016/j.jsat.2014.10.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2014] [Revised: 10/18/2014] [Accepted: 10/27/2014] [Indexed: 02/01/2023]
Abstract
Surveys indicate that substance use is prevalent in populations with schizophrenia. Family members may be able to support brief interventions (BI). We conducted a randomised controlled trial with 6-month follow-up among adult patients with schizophrenia and related psychoses who were referred to two hospitals in southern Thailand. Patients with psychosis were screened using the Alcohol Smoking and Substance Involvement Screening Test (ASSIST). 169 participants (all at moderate substance risk on the ASSIST) were randomised to receive simple advice (the clinics' treatment-as-usual, TAU condition), or single-session brief intervention (BI), or a single-session BI with family support (BI-FS). Given observed substance use, the primary outcome was the ASSIST tobacco smoking involvement score (SIS). Secondary outcomes were cigarettes smoked per day, change motivation (Taking Steps from the Stages of Change and Treatment Eagerness Scale), and DSM-IV Axis V Global Assessment of Relational Functioning (GARF). At follow-up, BI-FS participants reported a lower SIS (mean difference, -2.82, 95% confidence interval [CI] -4.84 to -0.81; Glass' effect size [Δ] = 0.57, 95% CI 0.19 to 0.95), smoked fewer cigarettes per day (mean difference -3.10, 95% CI -5.45 to -0.74; Δ = 0.56, 95% CI 0.18 to 0.94), had greater change motivation (mean difference 3.05, 95% CI 0.54 to 5.57; Δ = 0.41, 95% CI 0.03 to 0.79) and GARF (mean difference 6.75, 95% CI 1.57 to 11.93; Δ = 0.54, 95% CI 0.16 to 0.92). The BI-FS group also had better relational functioning in comparison to those receiving BI only (mean difference 5.44, 95% CI 0.20 to 10.67; Δ = 0.46, 95% CI 0.08 to 0.84). In schizophrenia and related psychoses, a brief intervention supported by a family member reduces smoking involvement, cigarette smoking intensity, and increases change motivation and relational functioning.

Abstract
OBJECTIVES Stimulants may worsen psychotic symptoms but there is limited evidence about the impact of stimulant abuse in people with schizophrenia. This study examined the prevalence and correlates of stimulant and other drug disorders in a population-based sample of people with schizophrenia, examining associations with frequent service use, physical health comorbidities and accommodation instability. METHODS New South Wales (NSW) hospital, community mental health and emergency department data were used to examine health service contact over 5 years in 13,624 people with a diagnosis of schizophrenia. Associations of stimulant disorders were examined with multinomial logistic regression, comparing people with no substance disorders to those with cannabis disorders, stimulant disorders or both. RESULTS Of people with schizophrenia, 51% had substance disorders, including 14% with stimulant disorders. Stimulant disorders were more common in young adults and in urban areas, less common in migrants, and unrelated to initial social disadvantage. More than 80% of those with stimulant disorders also had cannabis disorders. Service use and harms were most common in this group, including frequent mental health admissions (59%), frequent emergency department presentations (52%), admissions with injury or self-harm (44%), infectious disease diagnoses (22%), multiple changes of residence (61%), movement to more disadvantaged locations (42%) and periods of homelessness (18%). People with stimulant disorders alone had higher rates of self-harm, infectious disease and non-mental health admissions than people with cannabis disorders alone. CONCLUSIONS Stimulant disorders occur in people with schizophrenia and in first-episode psychosis at rates more than 10 times that of the broader population. Stimulant disorders are likely to worsen the burden of psychosis, and strategies are needed to engage and support the highly disadvantaged group of people with schizophrenia who have cannabis and stimulant disorders.

Abstract
BACKGROUND Cannabis use is high amongst young people who have recently had their first episode of psychosis, and is associated with worse outcomes. To date, interventions to reduce cannabis consumption have been largely ineffective, and it has been suggested that longer treatment periods are required. METHOD In a pragmatic single-blind randomized controlled trial 110 participants were randomly allocated to one of three conditions: a brief motivational interviewing and cognitive behavioural therapy (MI-CBT) intervention (up to 12 sessions over 4.5 months) with standard care from an early intervention service; a long MI-CBT intervention (up to 24 sessions over 9 months) with standard care; or standard care alone. The primary outcome was change in cannabis use as measured by Timeline Followback. RESULTS Neither the extended nor the brief interventions conferred benefit over standard care in terms of reductions in frequency or amount of cannabis use. Also the interventions did not result in improvements in the assessed clinical outcomes, including symptoms, functioning, hospital admissions or relapse. CONCLUSIONS Integrated MI and CBT for people with cannabis use and recent-onset psychosis does not reduce cannabis use or improve clinical outcomes. These findings are consistent with those in the published literature, and additionally demonstrate that offering a more extended intervention does not confer any advantage. Many participants were not at an action stage for change and for those not ready to reduce or quit cannabis, targeting associated problems rather than the cannabis use per se may be the best current strategy for mental health services to adopt.

Abstract
BACKGROUND AND AIMS Alcohol use disorders are common among people with psychosis and are associated with poorer prognoses. In psychosis patients, there are inconsistent findings regarding the link between alcohol disorders and clinical symptomatic outcomes. This study examined the relationships between alcohol consumption and specific clinical outcomes, including affective symptoms, in psychosis. METHODS Participants were recruited from secondary care services in the United Kingdom. Two hundred and ten participants whose substance use met inclusion for an alcohol disorder were compared with other substance users (n = 117) on baseline demographic, clinical and substance use variables. The alcohol subgroup was assessed at three time-points, with repeated measures of psychopathology and alcohol use over a 2-year period. Generalized estimating equations (GEE) models were used to examine whether change in alcohol use was associated with change in clinical outcomes. We controlled for a wide range of potential confounds, including other substance use. RESULTS A small but specific effect was evident for change in the quantity of alcohol consumed on change in depression (adjusted coefficient for 10 total units over 90 days: 0.0015, P = 0.047). Alcohol consumption was not associated with subsequent severity of psychotic symptoms (adjusted coefficient for Positive and Negative Syndrome Scale general for 10 average daily units 0.2492, P = 0.420) or severity of anxiety symptoms (adjusted coefficient for 10 average daily units 0.0534, P = 0.473). CONCLUSIONS For people with psychosis, the most detrimental effect of alcohol consumption appears to be its effect on mood. Some of this effect seems to be reversible, with drinking reduction associated with subsequent mood improvement.

Abstract
In the context of the development of early intervention for first-episode psychosis, this manuscript reviews new data with respect to its incidence, risk factors and evolution. Annual incidence of non-affective psychosis appeared to be between 14 and 30/100,000 in people aged 18-64. Incidence decreases with age and is twice higher in men than in women. There is an interaction between age and gender; the risk of psychosis decreases with age faster in men than in women. Thus, for schizophrenia, incidence rate is twice higher in men under 45 year-old and similar in both genders after. There is evidence that genetic and environmental factors may cause enduring liability to psychotic disorder, and, in addition, that genes and environment may interact synergistically. Some environmental factors have been identified; they concern foetal life, childhood or adolescence and may be conceptualized at the individual or the contextual level. The definition of recent onset psychosis may be based on duration of psychosis, between two and five years. Its development is identified through the occurrence of major psychotic symptoms, such as positive, negative symptomatology or disorganization, and impairment of social functioning. The types and patterns of occurrence and of evolution of psychotic symptoms have a prognostic impact. A long duration of untreated psychosis impacts symptomatology. It is associated with less severe positive symptoms at baseline and more severe after three years, insidious onset, male gender, early onset, and diagnosis of schizophrenia. Recent onset psychosis is often associated with comorbidities, such as depression, anxiety disorders, suicidal behaviours, and addiction. Symptomatic remission rates are found between 25 and 60%. Symptomatic and functional remissions favour each other. A third to half of patients is active, employed or students. Symptoms and evolution are various in studies, probably corresponding to various patho-physiological mechanisms.

Abstract
OBJECTIVE To compare the symptoms and social function of patients with psychosis and current substance use to those with psychosis and no history of substance use. METHOD The databases EMBASE, MEDLINE and PsycINFO were searched for peer-reviewed publications in English that reported the characteristics of patients with psychotic illness who were current substance users and those who had never used substances. The searches yielded 22 articles that met the inclusion criteria. Meta-analysis was used to compare four key outcome variables: positive symptoms, negative symptoms, depression and social function - and three secondary outcomes: violence, self-harm and hospital admissions. RESULTS Current substance-using patients were significantly younger than non-substance-using patients and were more likely to be male, but did not differ in age at onset of psychosis or in their level of education. Current substance users had higher ratings of positive symptoms and were more likely to have a history of violence. Older studies reported a stronger association between current substance use and positive symptoms than more recently published studies. Current substance users did not differ from non-users on measurements of negative symptoms, depressive symptoms, social function, self-harm, or the number of hospital admissions. CONCLUSION Current substance users with psychosis may have more severe positive symptoms than patients who have never used substances, but this result should be interpreted with caution because of demographic differences between substance users and non-substance users.

Abstract
Co-occurring substance use disorders (SUD), including alcohol, are common in schizophrenia (SZ) and are associated with poor outcome. Emerging data suggest that individuals with SZ have a dysfunctional brain reward circuit that may underlie their frequent use of alcohol and other substances, and further, that the atypical antipsychotic, clozapine (CLOZ), limits alcohol/substance use in these individuals, potentially by ameliorating this brain reward circuit dysfunction. To explore this hypothesis, reward functioning in a SZ sample with a history of co-occurring SUD, treated with either CLOZ (n=13) or typical antipsychotic agents (TYP), haloperidol or fluphenazine (n=14), as well as healthy controls (n=16), was evaluated through ratings of pleasurable and aversive odors, stimuli that are processed by several neural structures thought to play a key role in processing rewarding stimuli. Results suggest that CLOZ treatment is associated with broadening and strengthening the hedonic experience of these rewarding olfactory stimuli, both of a pleasant and unpleasant nature. This hedonic appraisal of odors appeared to be independent of odor perception (intensity ratings) and clinical symptoms. These preliminary findings provide important new data in support of the hypothesis that CLOZ ameliorates some aspects of abnormal brain reward functioning in individuals with co-occurring SZ and SUD. Further research may have valuable treatment implications for this population including interventions for other reward-associated deficits in learning, social interactions and other aspects of behavior and cognition.

Abstract
Longitudinal studies on first-episode psychosis (FEP) patients have shown a decrease of substance use disorders (SUDs) over the first years of illness, but there has been less focus on the gender aspect. The present study examines stability of alcohol and illicit substance use, with specific focus on gender, in a one year follow-up investigation of 154 FEP patients (91 men, 63 women) in Oslo, Norway, using criteria for DSM-IV substance use disorder diagnosis, the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT). The results show that cannabis was the most frequently used illicit substance at both times. Significantly more men (34%) than women (13%) had a current illicit SUD at baseline. At follow-up, the rate of illicit SUDs was significantly reduced in men (18%) but not in women (11%). There were no significant gender differences in the rate of current alcohol use disorders (AUD) (men 14%; women 8%) at baseline, and no significant reduction in AUD in any of the genders at follow-up. At follow-up, total AUDIT and DUDIT scores were reduced in men only. In conclusion, the high and persistent rate of SUDs, particularly of cannabis, among men and women during the first year of treatment for psychosis should be addressed in the clinical management of the patients. Female FEP patients who are also substance users may be particularly vulnerable in this regard and warrant closer attention.

Abstract
BACKGROUND Substance misuse is a well-recognized co-morbidity to psychosis and has been linked to poor prognostic outcomes in patients. Researchers have yet to investigate the difference in rates and characteristics between first-episode Substance Induced Psychosis (SIP) and primary psychosis. We aimed at comparing patients with SIP to primary psychosis patients with or without substance misuse at baseline. METHODS Thirty SIP patients, 45 primary psychosis patients with substance misuse (PS) and 66 primary psychosis patients without substance misuse (PNS) in a well-defined Norwegian catchment area were included from 2007-2011. Assessments included symptom levels (PANSS), diagnostic interviews (SCID), premorbid function scale (PAS) and global functioning (GAF f/s). RESULTS Treated incidence for SIP was found to be 6.5/100 000 persons per year, 9.7/100 000 persons per year for PS and 24.1/100 000 persons per year for PNS (15-65 yrs). Patients who had substance misuse (PS and SIP) were more likely to be male. Duration of Untreated Psychosis (DUP) was significantly shorter in the SIP group (5.0 wks., p = 0.003) and these had more positive symptoms on the PANSS (p = 0.049). SIP patients also did poorer on early youth academic levels on the PAS. CONCLUSIONS Yearly treated incidence of SIP is 6.5/100 000 persons per year in a Norwegian catchment area. SIP patients have short DUPs, are more likely to be male, have more positive symptoms at baseline and poorer premorbid academic scores in early adolescence. Follow-up will evaluate stability of diagnosis and characteristics.

Abstract
This article reviews the literature for the most pressing diagnostic and treatment challenges faced in working with adolescents. Diagnosing the treatment interventions required for this population involve psychoeducation, engagement of the patient and family in the treatment process, and use of antipsychotic medications. Cannabis may be a causal risk factor in psychotic illness, and data support recommendations to reduce or cease cannabis use in this population. Treatment strategies are discussed that are effective in adult patients and that may be efficacious for youth to abstain from substances after the resolution of psychotic symptoms.

Abstract
OBJECTIVES The aim of this naturalistic study was to assess course and predictors of symptomatic remission in outpatients with first-episode psychosis during quetiapine monotherapy. METHODS In 131 outpatients presenting with first-episode psychosis, socio-demographic and clinical variables including PANSS-8 and CGI-S scores were compared at baseline and follow-up between the subgroups with and without symptomatic remission during 12 weeks of flexible-dose treatment with quetiapine. RESULTS Logistic regression revealed a low degree of negative symptoms at baseline, younger age, shorter duration of psychotic episode, early treatment response, and the absence of concomitant diseases as predictors for symptomatic remission whereas general disease severity, PANSS-8 total score, gender, alcohol or substance abuse had no predictive value. CONCLUSIONS Our study underlines the predictive value of early treatment response and a low degree of negative symptoms in outpatients with first-episode psychosis. It also confirms the usability of the symptomatic remission criterion as a cross-sectional threshold criterion in clinical practice.

Abstract
OBJECTIVE To compare the symptoms and function of patients with psychosis who have ceased using substances to those who have psychosis but do not have a history of substance use. METHOD The databases EMBASE, MEDLINE and PsycINFO were searched for peer-reviewed publications in English reporting the characteristics of patients with psychotic illness who had stopped using substances and those who had never used substances. The searches yielded 20 articles that met the inclusion criteria. Four key outcome variables - positive symptoms, negative symptoms, depression and global function - and four other outcome measures reported in five or more studies were examined using meta-analysis. RESULTS Former substance-using patients were significantly younger than non-substance-using patients and were more likely to be male, but did not differ in age at onset of psychosis or in their level of education. There were no significant differences between former substance users and non-substance users in ratings of positive symptoms, negative symptoms, depression or global function. Among first-episode patients there was a trend towards former substance users having less severe depressive symptoms than non-substance users. In contrast, among non-first-episode patients, former substance users had significantly more depressive symptoms than non-substance users. In studies rated as being of higher quality, former substance users had significantly less severe positive symptoms than non-substance users. CONCLUSION The absence of significant differences between the two groups suggests that a history of substance use is not a poor prognostic indicator for patients who are able to stop using substances.

Screening for substance use disorders in first-episode psychosis: implications for readmission. Schizophr Res 2013; 146:125-31. [PMID: 23517662 PMCID: PMC4390132 DOI: 10.1016/j.schres.2013.02.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2012] [Revised: 02/05/2013] [Accepted: 02/24/2013] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Screening of substance use may prove useful to prevent readmission after the first episode of psychosis. The aim of the present study was to evaluate the influence of drug use on readmission risk in a first-episode psychosis sample, and to determine whether the cannabis/cocaine subscale of the Dartmouth Assessment of Lifestyle Inventory (DALI) is a better predictive instrument than urinary analysis. METHODS After admission, first-episode psychotic patients were interviewed for substance use and assessed with the DALI scale. They also underwent blood and urine sampling. Time to readmission was studied as a dependent outcome. The Kaplan-Meier estimator was applied to estimate the survival curves for bivariate analysis. The Cox proportional hazards model for multivariate analysis was assessed in order to control for potential confounders. ROC curve and validity parameters were used to assess validity to detect readmission. RESULTS Fifty-eight patients were included. The DALI cannabis/cocaine subscale and urinalysis were associated with increased readmission risk in survival curves, mainly the first five years of follow-up. After controlling for potential confounding variables for readmission, only the DALI cannabis/cocaine subscale remained as a significant risk factor. In terms of validity, the DALI cannabis/cocaine subscale was more sensitive than urinalysis. Alcohol assessments were not related to readmission. CONCLUSIONS The findings demonstrated that a quick screening self-report scale for cannabis/cocaine use disorders is superior to urinary analysis for predicting readmission. Future research should consider longitudinal assessments of brief validated screening tests in order to evaluate their benefits in preventing early readmission in first-episode psychosis.

Abstract
OBJECTIVE Excessive alcohol consumption is common among people with psychotic disorders. While there is an extensive literature on the efficacy of psychological treatments for excessive drinking, few studies have examined interventions addressing this issue among people with psychotic disorders. METHOD Systematic searches in PubMed and PsycINFO were conducted to identify randomized controlled trials comparing manual-guided psychological interventions for excessive alcohol consumption among individuals with psychotic disorders. Of the 429 articles identified, seven met inclusion criteria. Data were extracted from each study regarding study sample characteristics, design, results, clinical significance of alcohol consumption results, and methodological limitations. RESULTS Assessment interviews, brief motivational interventions, and lengthier cognitive behavior therapy have been associated with reductions in alcohol consumption among people with psychosis. While brief interventions (i.e. 1-2 sessions) were generally as effective as longer duration psychological interventions (i.e. 10 sessions) for reducing alcohol consumption, longer interventions provided additional benefits for depression, functioning, and other alcohol outcomes. CONCLUSION Excessive alcohol consumption among people with psychotic disorders is responsive to psychological interventions. It is imperative that such approaches are integrated within standard care for people with psychosis.

Abstract
OBJECTIVE To assess the extent to which ceasing the use of cannabis or other substances reduces the symptoms and social disability associated with psychotic illness. METHODS The electronic databases CINAHL, EMBASE, MEDLINE and PsycINFO were searched for peer-reviewed publications in English that report data about the characteristics of current and former substance-using patients diagnosed with psychotic illnesses. The searches yielded 328 articles, of which 23 studies met the inclusion criteria. Four key outcome variables; positive symptoms, negative symptoms, ratings of depression and global function, and five other measures of outcome that were reported in five or more studies were examined using meta-analysis. RESULTS Current substance-using patients were significantly younger than former substance-using patients (standardised mean difference (SMD) = -0.38), but did not differ in age at onset of psychosis, sex, level of education or marital status. Current substance users had higher scores on rating scales of positive symptoms (SMD = 0.29) and depression (SMD = 0.36), and lower scores on global function (SMD = -0.26) when compared with former substance users. There was a significant improvement in the ratings of positive symptoms, mood and global function among patients who stopped using substances during the first episode of psychosis, while improvements in the symptoms of patients with a more established psychotic illness did not reach statistical significance. CONCLUSION The results suggest that substance use contributes to both the symptoms and the burden of disability experienced by patients with psychosis. Patients in the early stages of psychotic illness should be informed about the benefits of giving up substances earlier, rather than later in the illness. Psychiatric services should regard the treatment of substance use as an integral part of the treatment of psychotic disorders.

Risk factors for relapse following treatment for first episode psychosis: a systematic review and meta-analysis of longitudinal studies. Schizophr Res 2012; 139:116-28. [PMID: 22658527 DOI: 10.1016/j.schres.2012.05.007] [Citation(s) in RCA: 310] [Impact Index Per Article: 25.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2011] [Revised: 04/04/2012] [Accepted: 05/05/2012] [Indexed: 12/12/2022]
Abstract
BACKGROUND Preventing relapse is an essential element of early intervention in psychosis, but relevant risk factors and precise relapse rates remain to be clarified. The aim of this study was to systematically compile and analyse risk factors for and rates of relapse in the early course of psychosis. METHODS Systematic review and meta-analysis of English and non-English language, peer-reviewed, longitudinal studies, with a minimum 12-month follow-up and at least 80% of participants diagnosed with a first episode of psychosis (FEP) that reported risk factors for relapse. RESULTS Of 153 potentially relevant articles, 29 were included in the study. Pooled prevalence of relapse of positive symptoms was 28% (range=12-47%), 43% (35-54%), 54% (40-63%) at 1, 1.5-2, and 3 years follow-up, in that order. A total of 109 predictors were analysed, with 24 being assessed in at least 3 studies. Of those, 20 predictors could be extracted for meta-analysis. Medication non-adherence, persistent substance use disorder, carers' critical comments (but not overall expressed emotion) and poorer premorbid adjustment, increased the risk for relapse 4-fold, 3-fold, 2.3-fold and 2.2-fold, respectively. CONCLUSIONS Clinical variables and general demographic variables have little impact on relapse rates. Conversely, non-adherence with medication, persistent substance use disorder, carers' criticism and poorer premorbid adjustment significantly increase the risk for relapse in FEP. Future studies need to address the methodological limitations of the extant research (e.g. definition of relapse), focus on the identification of protective factors and evaluate theoretically derived models of relapse.

Abstract
CONTEXT Longer duration of untreated psychosis (DUP) is known to be associated with poorer outcome of schizophrenia. DUP is also known to be longer in lower- and middle-income countries. Methodologically sound studies that have examined the association of DUP and outcome of schizophrenia in these countries are lacking. AIM The aim was to evaluate the association between DUP and outcome of never-treated schizophrenia patients. SETTING AND DESIGN This study was conducted at the National Institute of Mental Health and Neurosciences, Bangalore, using a prospective cohort design. MATERIALS AND METHODS 119 patients with schizophrenia/schizophreniform disorder diagnosed using the computerized diagnostic interview schedule for DSM-IV (CDIS-IV) were further assessed for DUP with the interview for retrospective assessment of onset of schizophrenia (IRAOS). After a mean (SD) follow-up period of 55.9 (37.2) weeks, the social and occupational functioning and psychopathology of 93 (80.2% of the surviving patients) patients were assessed using the social and occupational functioning scale (SOFS) and the positive and negative syndrome scale (PANSS), by raters blind to the DUP data. Spearman's correlation and Kendall's tau-B test were used to analyze the relationship between DUP and the outcome variables. RESULTS The mean DUP was 90.2 (median=30.1; SD=121.9) weeks. SOFS and PANSS scores at follow-up were statistically significantly associated with DUP, but not with other baseline variables (SOFS: rho=0.22, P=0.03; PANSS: rho=0.23, P=0.03). Among those with the shortest DUP (<16 weeks; n=33), 45.5%, 30.3%, and 24.2% had no impairment, mild-moderate impairment, and severe impairment, respectively. In contrast, 19.4%, 38.7%, and 41.9% of those with the longest DUP (>72 weeks; n=31) had no, mild-moderate, and severe impairment, respectively (Kendall's Tau-b=0.194; P=0.025). CONCLUSIONS The delay in accessing treatment among patients with psychosis is considerable in India, a lower- to middle-income country. Longer DUP is associated with poorer psychopathological and functional outcomes in persons with schizophrenia/schizophreniform disorder.

Abstract
OBJECTIVE People experiencing a first episode of psychosis frequently have co-occurring substance use disorders, usually involving alcohol and cannabis, which put them at risk for prolonged psychosis, psychotic relapse, and other adverse outcomes. Yet few studies of first-episode psychosis have addressed the course of substance use disorders and the response to specialized substance abuse treatments. METHODS The authors searched MEDLINE, PsycINFO, and other medical databases for English-language articles published between 1990 and 2009. Included studies addressed two research questions. First, do some clients become abstinent after a first episode of psychosis without specialized substance abuse treatments? Second, for clients who continue to use substances after a first episode of psychosis, does the addition of specialized substance abuse treatment enhance outcomes? RESULTS Nine studies without specialized substance abuse treatment and five with specialized substance abuse treatment assessed the course of substance use (primarily cannabis and alcohol) after a first episode of psychosis. Many clients (approximately half) became abstinent or significantly reduced their alcohol and drug use after a first episode of psychosis. The few available studies of specialized substance abuse treatments did not find better rates of abstinence or reduction. CONCLUSIONS Experience, education, treatment, or other factors led many clients to curtail their substance use disorders after a first episode of psychosis. Specialized interventions for others need to be developed and tested.

Abstract
Numerous studies have shown that patients with psychosis are more likely to use illicit drugs than the general population, with cannabis being the most popular. There exists overwhelming evidence that cannabis use can contribute to the onset of schizophrenia and poor outcome in patients with established psychosis. Therefore, understanding why patients use cannabis and whether they are motivated to change their habits is important. The evidence is that patients with psychosis use cannabis for the same reasons the general population does, to 'get high', relax and have fun. There is little support for the 'self-medication' hypothesis, while the literature points more towards an 'alleviation of dysphoria' model. There is a lack of research reporting on whether psychotic patients are ready to change their use of cannabis, which has obvious implications for identifying which treatment strategies are likely to be effective.

Abstract
Adolescence is a time of exploration of the self, and this exploration may involve the use of alcohol and drugs. Sadly, for some, adolescence also marks the first signs of a psychosis. The temporal proximity between the onset of substance use and of psychosis has been the cause of much debate. Here we review the association of alcohol, cannabis, stimulants, and other drugs with psychosis, and we conclude that the use of cannabis and the amphetamines significantly contributes to the risk of psychosis.

Abstract
AIMS The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is a brief, easily administered, valid and reliable screening instrument for all psychoactive substances in drug treatment and primary care settings. This study aims to determine the reliability and validity of the ASSIST for detecting substance use disorders in first-episode psychosis. PARTICIPANTS Participants were 214 first-episode psychosis patients attending the Early Psychosis Prevention and Intervention Centre (EPPIC) in Melbourne, Australia. MEASUREMENTS Participants were administered the ASSIST, Alcohol Use Disorders Identification Test (AUDIT), the Severity of Dependence Scale (SDS) and the Brief Psychiatric Rating Scale (BPRS). Presence of DSM-IV substance abuse and dependence disorders in the previous 12 months was assessed using the Structured Clinical Interview for DSM-IV (SCID-IV). FINDINGS The ASSIST total substance involvement (TSI) score and specific substance involvement (SSI) scores for cannabis, alcohol and amphetamine use demonstrated high levels of internal consistency and acceptable levels of concurrent and discriminative validity. Individuals with cutoff scores of >/=2, 4 and 1 on the ASSIST cannabis, alcohol and amphetamine SSI scores were 5 to 6 times more likely to meet the diagnostic criteria for these substance use disorders. CONCLUSIONS The ASSIST is a psychometrically sound measure of cannabis, alcohol and amphetamine use disorders in first-episode psychosis.

Abstract
BACKGROUND Substance misuse is a common comorbid problem in people presenting with first-episode psychosis and is associated with a poor short-term outcome. AIMS The aim of this study is to examine differences in baseline characteristics and 1-year outcome between individuals with first-episode psychosis who have never misused substances, those who stop misusing substances after initial presentation and those who persistently misuse substances over the 1-year assessment period. METHOD Patients were recruited to the Northern Ireland First Episode Psychosis Study (n = 272). Clinical assessments were performed at baseline and at 1 year (n = 194) and data were collected from the case notes. RESULTS Individuals with persistent substance misuse had more severe depression, more positive symptoms, poorer functional outcome and greater rates of relapse at 1 year than those who stopped and those who had never misused substances. There were no differences in outcome between people who had never misused substances and those who stopped misusing after presentation. CONCLUSIONS These results support assertive intervention targeted at comorbid substance misuse in individuals with first-episode psychosis.

Abstract
OBJECTIVE This paper sought to review current knowledge about the relationship between substance misuse and early psychosis. METHODS A literature search was conducted using Medline and restricting the search to articles after 1996. Additional articles were sourced from reference lists of relevant articles. RESULTS There is a high prevalence of substance misuse among persons with early psychosis, with cannabis and alcohol featuring prominently. Substance misuse is associated with earlier onset and possibly more positive symptoms, although apparently not with greater cognitive impairment. Cannabis appears to confer an increased likelihood of developing schizophrenia in biologically vulnerable individuals. Amphetamines also cause psychosis which may become chronic, although specific vulnerability to this effect is less well established. Many cases of so-called 'drug-induced psychosis' become diagnosed as schizophrenia in later years. Specific intervention programs report positive outcomes with regard to substance misuse and the course of psychosis. CONCLUSIONS Substance misuse should always be assessed in this patient group, bearing in mind the potential interactive causes of psychopathology. Intervention is of value in improving outcomes.

Abstract
AIM Examine substance misuse over the first 18 months of first-episode psychosis treatment. METHOD Clinicians rated alcohol and drug (mostly cannabis) misuse for 243 individuals followed prospectively. Assessments were completed at baseline and after 3, 6 and 18 months. Interventions relating to substance misuse included ongoing assessment of use, education and counselling to avoid. RESULTS Alcohol and drug misuse declined significantly between baseline and 3 months, especially among patients with a substance abuse or dependence diagnosis at baseline. Overall, these reductions were maintained over the 18-month follow-up period. The exception was worsening alcohol misuse over time among patients with alcohol abuse or dependence on entry. CONCLUSIONS With good usual care, education and support, alcohol and drug misuse declined significantly during the first months of psychosis treatment. The improvements in drug misuse were generally maintained over the 18-month follow-up, and worsening alcohol misuse over time may be the greater issue.

Abstract
OBJECTIVE To examine: i) changes in key outcome measures over time in treatment in a representative first-episode psychosis treatment cohort and ii) baseline predictors of service disengagement. METHOD Baseline characteristics of 236 patients were examined for associations with outcomes over time using generalized estimating equation models. The data on disengagement were analysed using logistic regression. RESULTS After controlling for admission scores, patients showed consistently improved outcomes while in treatment on functional recovery (unemployment, P < 0.01; HoNOS, P < 0.001; the Quality of Life Scale, P < 0.001; GAF, P < 0.05) but not symptomatology (as assessed by the PANSS and substance abuse). The 64 (33%) who disengaged were more likely to be unemployed (P < 0.01) and have higher HoNOS (P < 0.01) and GAF (P < 0.05) scores at baseline. CONCLUSION This evaluation has shown significant improvements in psychosocial functioning but not psychopathology during treatment at an Early Intervention for Psychosis Service. Despite attempts to retain patients, there is a high rate of treatment discontinuation.

Abstract
Traditional models of co-occurring substance misuse in psychosis, including the vulnerability and coping (self-medication) hypotheses, have tended to focus on state-specific factors, such as the severity of substance misuse or psychotic symptoms. In contrast, more recent personality models posit that co-morbidity is related to individual differences in stable trait-specific personality variables that underlie affective outcomes, coping strategies and subsequent risk for substance use. This paper reviews the current evidence base for these three models, and suggests that future research examine the inter-relationships between trait and state-specific personality, affective and behavioural variables on co-morbidity.

Abstract
BACKGROUND Differential association of risk factors associated with relapse following treatment of first-episode psychosis (FEP) have not been studied adequately, especially for patients treated in specialized early intervention (SEI) services, where some of the usual risk factors may be ameliorated. METHOD Consecutive FEP patients treated in an SEI service over a 4-year period were evaluated for relapse during a 2-year follow-up. Relapse was based on ratings on the Scale for Assessment of Positive Symptoms (SAPS) and weekly ratings based on the Life Chart Schedule (LCS). Predictor variables included gender, duration of untreated psychosis (DUP), total duration of untreated illness (DUI), age of onset, pre-morbid adjustment, co-morbid diagnosis of substance abuse during follow-up and adherence to medication. Univariate analyses were followed by logistic regression for rate of relapse and survival analysis with the Cox proportional-hazards regression model for time to relapse as the dependent variables. RESULTS Of the 189 eligible patients, 145 achieved remission of positive symptoms. A high rate of medication adherence (85%) and relatively low relapse rates (29.7%) were observed over the 2-year follow-up. A higher relapse rate was associated with a co-morbid diagnosis of substance abuse assessed during the follow-up period [odds ratio (OR) 2.84, 95% confidence interval (CI) 1.24-6.51]. The length of time to relapse was not associated with any single predictor. CONCLUSIONS Specialized treatment of substance abuse may be necessary to further reduce risk of relapse even after improving adherence to medication.
