Personality domains, duration of untreated psychosis, functioning, and symptom severity in first-episode psychosis

OBJECTIVES

Early-course psychotic disorders have been extensively studied in terms of phenomenology, but little is known about the influence of personality traits on clinical features of first-episode psychosis. The aim of this study was to explore how the "big five" personality domains (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are associated with treatment delay (duration of untreated psychosis, DUP), functioning, and positive and negative symptom severity.

METHODS

Data for these analyses were obtained from 104 participants enrolled from psychiatric inpatient units in Atlanta, Georgia, between August 2008 and March 2011. The NEO Five-Factor Inventory (NEO-FFI) was used to assess personality domains, and all other variables were measured in a standardized and rigorous manner using psychometrically sound instruments. Correlational analyses and multiple linear regressions were carried out to examine the strength of associations between variables of interest.

RESULTS

Findings indicated that except for openness, all of the other personality variables contributed to some extent to the variance in DUP. Conscientiousness was positively correlated with functioning. Agreeableness was independently negatively associated with positive symptom severity and extraversion was independently negatively correlated with negative symptom severity.

CONCLUSIONS

We report the first evidence suggesting that DUP is in part driven by personality domains. Functioning and symptom severity are also associated with those domains. Personality should be taken into account in order to better understand the phenomenology of early-course psychotic disorders as well as treatment-seeking behaviors.

Prodromal symptoms and remission following first episode psychosis

INTRODUCTION

Describing the trajectory of prodromal symptoms has obvious appeal in supporting advances towards sub-clinical intervention. Identifying clinical phenomena associated with unfavourable illness outcomes could have greater significance in explaining some heterogeneity within and between psychotic disorders and advancing understanding of pre-psychotic typologies. Few studies have assessed the continuity, if any, between prodromal phases and illness outcome one year after treatment.

METHODS

We assessed 375 people with first-episode psychosis (FEP) and 215 (57.4%) were seen approximately one year later. We performed factor analysis on prodromal symptom items obtained by interview with families and participants and identified a five-factor solution. We determined whether these factors predicted non-remission from psychosis in the presence of other factors that may predict outcome including premorbid adjustment, duration of prodrome and untreated psychosis (DUP), baseline symptoms and DSM-IV diagnoses. We used random forest classification to predict the most important variables and logistic regression to identify specific predictors.

RESULTS

We identified five prodromal symptom factors comprising Negative Symptoms, General Psychopathology, Reality Distortion, Strange Ideas and Irritability. Prodromal symptoms did not predict a greater risk of non-remission with the exception of Irritability and this factor was also associated with earlier age at onset, being male and a diagnosis of substance-induced psychosis. Being male, DUP and baseline positive symptoms predicted non-remission at one year.

CONCLUSION

Prodromal symptoms were not linked with outcome after a year of treatment which could be explained by greater heterogeneity in illness psychopathology which may be more pronounced in broad FEP diagnoses at different stages. It could also be explained by prodromal symptoms exerting greater influence earlier in the course illness.

Effect of time and duration of untreated psychosis on cognitive and social functioning in Chinese patients with first-episode schizophrenia: A 1-year study

BACKGROUND

Duration of untreated psychosis (DUP) is believed to exert a deleterious effect on cognitive and social function. However, to date, results remain inconclusive.

AIMS

To investigate the effect of time and DUP on cognitive and social functioning in first-episode schizophrenia (FES) subjects in Shanghai, China.

METHODS

FES patients were subjected to a comprehensive neuropsychological battery, the Personal and Social Performance scale (PSP) and the Positive and Negative Symptoms Scale (PANSS) at baseline, 6 month and 1 year. DUP was defined as the time from onset of first psychotic symptoms to first contact made with psychiatric services.

RESULTS

Though the rate of non-completers in our observational study was relatively high (40%), we did not find any significant differences between the completers and non-completers (P-values > 0.05). Significant impairments in verbal learning and memory and executive function were noted over the course of 1 year. Meanwhile, social function improved significantly over the course of 1 year. Although, DUP did not share any significant relationship with cognitive or social function the effect estimate (range: - 0.03 to 0.02) of an increase of 1 month in DUP was clinically non-negligible in this study.

CONCLUSIONS

In Chinese FES patients, the longitudinal course of cognitive function tends to worsen in verbal learning and memory, executive function and motor speed, while that of social function tends to improve. DUP was not found to be associated with cognitive or social deterioration in Chinese FES.

School-based approaches to reducing the duration of untreated psychosis

Students with emerging psychosis often experience delays in diagnosis and treatment that impact mental health and academic outcomes. School systems have tremendous potential to improve early identification and treatment of adolescent psychosis. As a community-based resource, schools can support outreach, education, and screening for adolescents with psychosis and engage identified students and their families for treatment. The concept of duration of untreated psychosis (DUP; the gap between symptom onset and treatment initiation) in adolescent psychosis and the potential role of schools in reducing DUP are reviewed. Future directions for clinical care and research needed to support school-based interventions are proposed.

The development of insight and its relationship with suicidality over one year follow-up in patients with first episode psychosis

OBJECTIVE

Insight into psychosis has been linked to suicidality, although inconsistently. The co-variation between insight and suicidality over time is under-investigated. The aim of the present study was to investigate predictors of suicidality in patients with first episode of psychosis (FEP) over one year, focusing on the relationship between insight and suicidality.

METHODS

Patients with FEP (n=146) were interviewed as soon as possible after treatment starts and at one year follow-up.

RESULTS

At baseline 37% of patients were suicidal, significantly reduced to 20% at follow-up. The effect of insight on suicidality was in different directions at different time-points, with insight at baseline increasing and insight at follow-up decreasing the risk of suicidality at follow-up. Patients with stable levels of insight across baseline and follow-up did not differ in risk for suicidality at follow-up. However, patients who lost insight from baseline to follow-up were more often suicidal at follow-up, whilst patients who gained insight were more seldom suicidal at follow-up. Other predictors of suicidality at follow-up were more depressive episodes before study entry, longer duration of untreated psychosis, more suicide attempts six months prior to follow-up, and depression at follow-up.

CONCLUSION

The results indicate that the effect of insight on suicidality in FEP-patients depends on time of assessment and of changes in insight. Gaining insight during treatment was associated with reduced risk for suicidality, whilst losing insight had the opposite effect, underlining the need to monitor insight over time and tailor interventions according to illness phase.

Minimal evidence that untreated psychosis damages brain structures: a systematic review

INTRODUCTION

A longer duration of untreated psychosis (DUP) is associated with poor outcomes in first-episode psychosis (FEP); however, it is unclear whether this is due to the effects of psychosis on brain structure. We systematically reviewed the literature on the association between the length of untreated psychosis and brain structure in first-episode psychosis.

METHODS

We searched three electronic databases and conducted forward and backward citation searching to identify relevant papers. Studies were included if they: (1) included patients with a psychotic disorder who were treatment naïve or minimally treated; and (2) had correlated measures of DUP or duration of untreated illness (DUI) with structural measures.

RESULTS

We identified 48 studies that met the inclusion criteria. Forty-three examined the correlation between DUP and brain structure, and 19 examined the correlation between DUI and brain structure. There was evidence of significant associations in brain regions considered important in psychosis; however, the proportion of significant associations was low and the findings were inconsistent across studies. The majority of included studies were not primarily designed to examine whether DUP/DUI is correlated with brain structure, and there were methodological limitations in many studies that prevent drawing a strong conclusion.

CONCLUSION

To date, there is minimal evidence of an association between untreated psychosis and brain structure in FEP. Although the body of literature is substantial, there are few hypothesis-driven studies with a primary objective to answer this question. Future studies should be specifically designed to examine whether untreated psychosis has a deleterious effect on brain structure.

History of offending behavior in first episode psychosis patients: a marker of specific clinical needs and a call for early detection strategies among young offenders

OBJECTIVES

Previous literature suggests that early psychosis (EP) patients with a history of offending behavior (HOB) have specific clinical needs. The aims of this study were to assess: (1) the prevalence of HOB in a representative sample of EP; (2) the premorbid and baseline characteristics of patients with HOB, and (3) the potential differences in short-term outcome of such patients when compared to patients without HOB.

METHODS

The Early Psychosis Prevention and Intervention Centre (EPPIC) admitted 786 EP patients between 1998 and 2000. Data were collected from patients' files using a standardized questionnaire. Data of 647 patients could be analyzed.

RESULTS

HOB patients (29% of the sample) were more likely to be male with lower level of premorbid functioning and education, have used illicit substances and have attempted suicide. They presented with a more complex clinical picture and had poorer 18-month outcome. Most importantly, they had a significantly longer duration of untreated psychosis.

CONCLUSIONS

On the basis of the high prevalence and specific features of EP patients with HOB, our study confirms a need for additional research in this domain and for the development of specific treatment strategies. Most importantly, it suggests a need for the promotion of early detection strategies among the populations of young offenders, considering that some of them may be going through the early phases of a psychotic disorder and that reduction of treatment delay and provision of well adapted interventions may have a significant impact at numerous levels in such patients.

The efficacy of targeted health agents education to reduce the duration of untreated psychosis in a rural population

The duration of untreated psychosis (DUP) is a key determinant in the severity of symptoms in patients with schizophrenia. DUP is a modifiable factor that if reduced can improve patient outcome and treatment response. We sought to decrease DUP in rural Argentina by instituting annual training of local health agents to better identify signs of mental illness and offer earlier intervention. DUP was estimated using Schedules of Clinical Assessment in Neuropsychiatry (SCAN). Ongoing training was correlated with a reduction in DUP. Reducing DUP through better screening can decrease the psychosocial burden of disease and improve the trajectory of psychosis.

Reliability and validity of methods for measuring the duration of untreated psychosis: a quantitative review and meta-analysis

BACKGROUND

The duration of untreated psychosis (DUP) has been associated with a wide range of clinical outcomes, and is considered to be one of the key parameters in managing clinical high risk and first episode psychosis patients. However, considerable discrepancies exist in the way that DUP is estimated in different studies. There is no standard or consensus on which method is most reliable and valid for assessing DUP.

METHODS

This review aimed to quantitatively assess different DUP measurement instruments and definitions by comparing their inter-rater reliability, and their strength of validity in predicting biological and clinical outcomes.

RESULTS

Nine instruments designed for measuring DUP were found. Their inter-rater reliability were found to be adequate to excellent, although quite varied. This analysis did not show that any instrument was clearly outstanding compared to the others, although the limited available data do not exclude this possibility. DUP was also significantly associated with a range of outcomes, although mostly with small effect sizes. However, non-instrument based, ad hoc clinical interviews remained the most common way of measuring DUP. Definitions of onset of psychosis and onset of treatment were inconsistent among studies.

CONCLUSIONS

This review did not find quantitative evidence to support the use of one instrument over another. DUP remains a promising modifiable risk factor for a range of long-term clinical outcomes. Future research should quantify and improve the reliability and validity of the structured instruments for DUP measurement.

Impact of early intervention services on duration of untreated psychosis: data from the National EDEN prospective cohort study

OBJECTIVE

This study aimed to determine if the inception of Early Intervention Services (EISs) is followed by an improvement in the prompt treatment of people with first episode psychosis.

METHOD

A prospective cohort study of referrals to new and established EISs was conducted at 1, 2, 3, and 4 years after inception of new EIS. The study was conducted with 14 (seven new and seven established) secondary care EIS within geographically defined catchment areas in England between 2005 and 2009. Participants included 1027 consecutive referrals to EIS aged 14-35 with a first episode of psychosis. Duration of untreated psychosis (DUP) and number of participants treated adequately within 6 months of onset were the main outcome measures.

RESULTS

A significant downward trend across yearly cohorts for DUP for new EIS (F1,549=8.4, p=0.004) but not for established EIS (F1,429=1.7, p=0.19) was observed. There was a significant upward trend across cohorts in the proportion of referrals treated within 6 months for new EIS (X(2)=8.0, df=1, p=0.005), but not for established EIS (X(2)=0.1, df=1, p=0.72).

CONCLUSION

The introduction of new EIS was followed by a reduction in DUP and an increase in the proportion of patients treated within 6 months of onset. These trends were not present in the catchment areas of established services where DUP was initially lower, suggesting that there was no general tendency for DUP to fall over time. Hence, the introduction of an EIS was followed by an improvement in the prompt and proper treatment of first episode psychosis.

Factors contributing to the duration of untreated psychosis

BACKGROUND

Shortening the duration of untreated psychosis (DUP) - with the aim of improving the prognosis of psychotic disorders - requires an understanding of the causes of treatment delay. Current findings concerning several candidate risk factors of a longer DUP are inconsistent. Our aim was to identify factors contributing to DUP in a large sample that represents the treated prevalence of non-affective psychotic disorders.

METHOD

Patients with a non-affective psychotic disorder were recruited from mental health care institutes from 2004 to 2008. Of the 1120 patients enrolled, 852 could be included in the present analysis. Examined candidate factors were gender, educational level, migration status, premorbid adjustment and age at onset of the psychotic disorder. DUP was divided into five ordinal categories: less than one month, one month to three months, three months to six months, six months to twelve months and twelve months and over. An ordinal logistic regression analysis was used to identify the risk factors of a longer DUP.

RESULTS

Median DUP was less than one month (IQR 2). The factors migration status (p=0.028), age at onset of the psychotic disorder (p=0.003) and gender (p=0.034) were significantly associated with DUP in our analysis.

CONCLUSION

First generation immigrant patients, patients with an early onset of their psychotic disorder and male patients seem at risk of a longer DUP. These findings can assist in designing specific interventions to shorten treatment delay.

Prospective relationship between duration of untreated psychosis and 13-year clinical outcome: a first-episode psychosis study

BACKGROUND

The adverse effects of a long duration of untreated psychosis (DUP) have been explored in numerous short-term studies. These studies support the development of early interventions that reduce treatment delay and promote recovery. However, the enduring impact of DUP is largely unknown, partly due to the paucity of prospective long-term studies. Although the DUP-outcome relationship is commonly assumed to be linear, the threshold effect has not been adequately examined.

OBJECTIVE

To explore the relationship between DUP and long-term symptomatic remission.

METHODS

This was a prospective study of a cohort of 153 first-episode psychosis patients in Hong Kong at the 13-year follow-up. The patients were categorized into short (≤30days), medium (31-180days) and long (>180days) DUP groups.

RESULTS

The long-term outcome was ascertained in 73% of the patients. Nearly half of the patients (47%) fulfilled the criteria for symptomatic remission. The short DUP group experienced a significantly higher remission rate over the course of the illness. The odds of long-term symptomatic remission was significantly reduced in the medium DUP (by 89%) and long DUP (by 85%) groups compared with the short DUP group. Further analysis showed that DUP had a specific impact on negative symptom remission.

CONCLUSION

The findings support the threshold theory that DUP longer than 30days adversely impacts the long-term outcome. The present study is one of the few studies that confirmed the enduring impact of DUP on long-term outcomes based on well-defined criteria and adequate statistical adjustment.

No sex differences in neuropsychological performance in first episode psychosis patients

OBJECTIVE

The purpose of this study was to verify whether male patients with psychosis have greater neurocognitive impairment than female patients at illness onset.

METHOD

Participants with a first episode of psychosis (74 women/86 men) and healthy controls (62 women/97 men) were assessed with an extensive neuropsychological test battery.

RESULTS

Women in the clinical group were older at illness onset and had achieved higher formal education than men. This trend was the same for the control group. The patient group presented with lower premorbid IQ compared to healthy controls, and performed below for most neuropsychological tests. Women scored higher than men on a test of verbal memory, whereas men scored higher than women on a test of reaction time, visual memory, and a planning task. There were no group-by-sex interactions for any of the neuropsychological tests.

CONCLUSION

The present study shows that at the onset of psychosis there are no differences between males and females in neuropsychological performance. The differential pattern of cognitive performance observed is similar to that in healthy males and females. Furthermore, females with a late onset of psychosis may represent a subgroup with specific visuospatial and problem solving impairments.

Predictors of cognition in first episode psychosis

PURPOSE

Cognitive deficits are common in the first episode of psychosis (FEP) and may begin much earlier. While some evidence suggests that the decline in cognition occurs over the untreated symptomatic period, including the prodromal phase, others point to these deficits being present even earlier. We aimed to investigate the differential effect of untreated symptomatic and pre-morbid phases on cognition in a large sample of FEP.

METHODS

Two hundred and sixty eight FEP patients, admitted into a specialized early intervention service, were administered neuro-cognitive tests. The Circumstances of Onset and Relapse Schedule (CORS) was administered for measurement of duration of untreated psychosis (DUP), the duration of untreated illness (DUI) and demographic factors. The Pre-morbid Adjustment Scale (PAS) was used to measure different domains of pre-morbid adjustment. Seventy three healthy controls were also recruited for neuro-cognitive comparison.

RESULTS

We observed no effect of DUP and a minimal effect of DUI on cognitive functioning in FEP. Instead, the early educational pre-morbid adjustment domain was most strongly associated with cognition and predicted both global cognitive and verbal memory outcome in FEP.

CONCLUSION

Our results suggest that symptoms associated with the symptomatic phase of a FEP do not influence cognitive functioning in FEP. Instead, cognitive deficits in FEP may predate illness onset and may indicate susceptibility to such illness.

Predictors of suicide in Asian patients with first episode psychosis

High rates of suicide have been reported in psychotic disorders, particularly in the early phases. Studies examining suicide risk during the first episode of psychosis (FEP) are lacking, especially in the Asian context. The present study aims to investigate the prevalence of completed suicides and associated risk factors in a multi-ethnic Asian society.

METHOD

Data from 1397 patients accepted into a local Early Psychosis Intervention Programme (EPIP) was collected. This included sociodemographic and clinical data. Cox proportional-hazards regression models were performed in order to explore factors associated with time to completed suicide.

RESULTS

The sample comprised of 1397 FEP patients, with 687 females and 710 males. The mean age was 28.2 years. The prevalence of suicide in this sample was 1.9%. Of the 26 FEP patients who committed suicide, data on time to suicide was available for 23 of them. 56.5% committed suicide during the first year of follow-up. A higher risk of suicide was associated with an older age (Hazard Ratio (HR)=1.31, 95% CI, 1.05-1.63), longer DUP (HR=1.05, 95% CI, 1.02-1.11), higher PANSS positive (HR=1.91, 95% CI, 1.37-2.67), higher GAF symptomatology (HR=1.16, 95% CI, 1.04-1.30) and GAF disability scores (HR=1.12, 95% CI, 1.02-1.22).

CONCLUSION

Older patients with longer DUPs, higher PANSS positive and negative scores and better functioning appear to be at higher risk of suicide in this sample. Early intervention services should focus on a thorough risk assessment in order to reduce the risk of suicide during FEP.

Parent abuse by adolescents with first-episode psychosis in Egypt

PURPOSE

To determine the rate of parent abuse in a sample of Egyptian adolescents with first-episode psychosis (FEP) and to identify the association between parent abuse and a number of sociodemographic and clinical factors of interest in these patients. As yet, the abuse of parents by their children, especially mentally ill children, in contrast to child abuse, has remained a research taboo.

METHODS

In a cross-sectional study in Zagazig (Egypt), a sample of 150 adolescent outpatients (82 boys; 68 girls), presenting with FEP, was assessed for the occurrence of parent abuse using both interview and questionnaire methods (Abused Parent Questionnaire, APQ). Univariate analyses were used to compare parent abusers and nonabusers along a number of sociodemographic and clinical variables. Variables that were associated with parent abuse were entered into a multivariate logistic regression analysis model.

RESULTS

We found that 61 patients (40.7%) perpetrated abuse against parents, mostly mothers (55/61; 90.2%). Five significant risk factors for parent abuse were identified by multivariate analysis. These were parent's female gender (95% CI = 7.82-45.56), patient's male gender (95% CI = 3.15-37.14), Childhood Trauma Questionnaire - Short Form total score (95% CI = 1.48-14.91), Positive and Negative Syndrome Scale positive subscale score (95% CI = 1.26-9.59), and duration of untreated psychosis (95% CI = 1.01-4.72).

CONCLUSIONS

The study indicates that parent abuse, particularly mother abuse, in untreated adolescents with FEP is an issue calling for increased awareness of the problem. The findings may have important implications for parental psychoeducation and support, and earlier access to treatment.

Declining social support in adolescents prior to first episode psychosis: associations with negative and affective symptoms

Social support for individuals with psychosis is associated with decreased symptom severity, improved outcomes, and recovery. In adolescents, declining social support prior to the first hospitalization has been shown to predict time to relapse, which may have implications for early intervention. Data were collected on adolescents (n=84) following a first hospitalization for a psychotic episode in order to examine how change in social support relates to the duration and type of untreated symptoms. Most adolescents experienced a decline in social support (n=46) prior to index hospitalization. Chi-square analyses showed that declining social support was related to negative symptoms and longer duration of untreated psychosis, whereas stable social support was associated with manic symptoms and diagnosis of Bipolar disorder. When entered together into a logistic regression model, the decline in social support was primarily explained by the type of symptoms, rather than by the duration of untreated symptoms. These findings are relevant for targeting psychosocial treatments toward adolescents who may have particular deficits in social support during the prodromal phase and first episode of psychosis.

Duration of untreated psychosis in adolescents: ethnic differences and clinical profiles

BACKGROUND

Duration of Untreated Psychosis (DUP) is an important measure associated with outcome of psychosis. This first study in the UK compared DUP between adolescent and adult-onset individuals and explored whether the adolescent-onset group showed variations in DUP that could be accounted for by sociodemographic and selected risk factors.

METHODS

This naturalistic cohort study included 940 new first-episode psychosis cases aged 14-35years (136 adolescent-onset versus 804 adult-onset psychotic individuals) referred to nine Early Intervention Services for Psychosis in London (2003-2009). Sociodemographic characteristics, age of onset, family history of mental illness, duration of untreated psychosis, suicidality and substance use information were collected at entry to the services.

RESULTS

Adolescents presented with significantly greater median DUP (179days) than adults (81days, p=0.005). Large differences in DUP were found amongst adolescent ethnic groups (median DUP: White: 454days; Black: 103days; Asian and mixed: 28.5days). In addition, younger age of onset and higher lifetime cannabis use were associated with longer treatment delay amongst adolescents.

CONCLUSIONS

This study of DUP in adolescent-onset psychosis found it to be approximately twice the length of DUP amongst adults. For the adolescent White sub-group, DUP was far greater than the UK Department of Health target (<3months). Both the high rates of lifetime cannabis use and the lower age of onset might explain the long DUP in this ethnic group. Physicians need to be particularly vigilant about identifying and managing early psychosis in adolescents.

Demographic, socio-environmental, and substance-related predictors of duration of untreated psychosis (DUP)

OBJECTIVE

Longer duration of untreated psychosis (DUP) is associated with poorer early-course and long-term outcomes, and is a target of early detection and intervention efforts. Given the paucity of research on childhood and adolescent stressors (e.g., maltreatment and neighborhood disorder) as potential predictors of DUP, limited research on premorbid substance use as a determinant of DUP, and inconclusive findings on the association between DUP and neurocognition, we conducted three sets of analyses to address these issues. Mode of onset of psychosis was also considered, given its established role as an illness-level correlate of DUP.

METHODS

We rigorously assessed DUP and other pertinent variables in 180 predominantly African American, low-income, and socially disadvantaged first-episode psychosis patients hospitalized in five psychiatric units.

RESULTS

Mode of onset of psychosis, prior incarceration, and the level of childhood/adolescent maltreatment were all significant independent predictors of DUP. Regarding premorbid substance use, having ever used cannabis and the amount of premorbid alcohol use were significantly associated with DUP. None of the seven neurocognitive domains assessed were even modestly, or clinically meaningfully, associated with DUP.

CONCLUSIONS

These and other findings on DUP may be informative for early detection and intervention services. For example, such services might benefit from special outreach to criminal justice settings and disadvantaged neighborhoods, and to young people likely to have a history of childhood/adolescent maltreatment and gradually developing psychotic symptoms.

Prospective study of duration of untreated psychosis and outcome of never-treated patients with schizophrenia in India

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.

Effects of duration of untreated psychosis on long-term outcome of people hospitalized with first episode schizophrenia

Duration of untreated psychosis (DUP) has emerged as a reliable predictor of outcome but continues to remain under scientific scrutiny. The present study examines the effect of differential periods of DUP on long-term outcome of first episode schizophrenia at Mumbai, India. This research was a prospective, 10-year follow-up naturalistic study. Hospitalized patients of first episode schizophrenia were selected and followed up. Results showed that the mean DUP was higher for a group which showed clinical recovery on Clinical Global Impression Scale [14.0 months (SD=8.0) in recovered and 10.8 months (SD=5.7) in non-recovered group (P=0.091)]. DUP was not found to be significantly associated with any of the end point parameters of good clinical or social outcome. Thus, this study found that DUP alone does not determine outcome status confirming the role of psychopathological heterogeneity.

Early intervention in schizophrenia

Early intervention (EI) programs in schizophrenia and other psychoses are aimed at early detection (ED) of the disease; prevent conversion to manifested psychosis and phase-specific treatment to reduce development of chronic disabilities. EI strategies include targeting people at "high risk" for developing schizophrenia, intervening in prodromal phase of schizophrenia, and reducing the "duration of untreated psychosis" (DUP). Services are delivered by a specialized team and are usually resource intensive. Several strategies like treatment with antipsychotics, family interventions, and cognitive behavior therapy have been tried with modest success in prodromal patients. Significant ethical reservations exist regarding exposing prodromal patients to the stigma of labeling as "high risk for schizophrenia" and side effects of psychotropics in the absence of clear evidence of efficacy in favor of ED, intervention by specialist teams, and phase-specific interventions in prodrome of psychosis. More research is warranted to demonstrate the risk-benefit and cost-benefit of such interventions before these can be routinely recommended.
