Reducing the duration of untreated first-episode psychosis: effects on clinical presentation

CONTEXT: Most studies on first-episode psychosis show an association between a long duration of untreated psychosis (DUP) and poorer short-term outcome, but the mechanisms of this relationship are poorly understood. OBJECTIVE: To determine whether it is possible to reduce the DUP for first-episode patients in a defined health care area through the introduction of an early detection (ED) program, compared with parallel health care areas without an ED program (No-ED). SETTING AND PATIENTS: We included consecutive patients with a DSM-IV diagnosis of nonorganic, nonaffective psychosis coming to their first treatment in the study health care areas between January 1, 1997, and December 31, 2000. A total of 281 patients (76% of the total) gave informed consent. INTERVENTIONS: The ED and No-ED health care areas offered an equivalent assessment and treatment program for first-episode psychosis. The ED area also carried out an intensive ED program. RESULTS: The DUP was significantly shorter for the group of patients coming from the ED area, compared with patients from the No-ED areas (median, 5 weeks [range, 0-1196 weeks] vs 16 weeks [range, 0-966 weeks]). Clinical status measured by the Positive and Negative Syndrome Scale and the Global Assessment of Functioning Scale was significantly better for patients from the ED area at start of treatment and, with the exception of Positive and Negative Syndrome Scale positive subscale, at 3 months. Multiple linear regression analyses gave no indication that confounders were responsible for these differences. CONCLUSIONS: It is possible to reduce the DUP through an ED program. The reduction in DUP is associated with better clinical status at baseline that is maintained after 3 months.     

Determinants of quality of life in first-episode psychosis

OBJECTIVE: To assess patient and/or illness characteristics associated with aspects of quality of life (QOL) in first-episode psychosis (FEP). METHOD: Patient characteristics, symptom ratings and Wisconsin QOL scale (client version) were assessed. Data were analysed with correlation coefficients and a hierarchical regression analysis. RESULTS: Patients presented with varying levels of QOL on different domains. The level of 'general satisfaction' was related to age of onset and social premorbid adjustment; 'weighted index of QOL' to social premorbid adjustment and inversely to educational premorbid adjustment; 'social relations' inversely to duration of untreated psychosis (DUP), length of prodrome and negative symptoms; 'psychological well-being' inversely to depression and educational premorbid adjustment; 'activities of daily living' to social premorbid adjustment and inversely to negative symptoms; and 'outlook on symptoms' to level of depression. CONCLUSION: Domains of self-rated QOL in FEP patients are differentially associated with malleable and non-malleable aspects of patient and illness characteristics.     

Psychosocial skills training on social functioning and quality of life in the treatment of schizophrenia: a controlled study in Turkey

OBJECTIVE This study assessed the impact of a psychosocial skills training program, consisting of psychoeducation, interpersonal group therapy and family education incorporated into social skills training, as an integrative approach on social functioning and quality of life of patients with schizophrenia, in comparison to standard care for an 8-month period.

METHOD Thirty patients with DSM-IV schizophrenia were included in the study. Patients were assessed using the Positive and Negative Syndrome Scale (PANSS), Quality of Life Scale (QLS), Social Functioning Scale (SFS), and Global Assessment of Function (GAF) at baseline. Fifteen patients underwent an 8-month psychosocial skills training group program and another fifteen patients (waiting list) continued in standard care. Both groups were reassessed and analyzed at the end of the study.

RESULTS Two groups were not statistically different in terms of total PANSS, QLS, SFS, GAF scores, and demographic characteristics at baseline. However, there was a significant improvement in the mean total QLS, SFS, GAF, and even in total PANSS scores (respectively from 64.46±19.58 to 89.67±24.10, P<0.001, from 93.20±22.85 to 132.60±33.85, P<0.002, from 57.40±8.78 to 63.86±7.57, P<0.012, and from 63.53±14.48 to 53.33±15.71, P<0.029) for those who underwent the PSST program, but there was no statistically significant change for those on standard care at the end of the study.

CONCLUSION This study highlights the ‘social functioning’ and ‘quality of life’ benefits of the psychosocial skills training program for patients with schizophrenia. It can be concluded that this comprehensive psychosocial skills training program might be an important contribution to the functioning of the patients.     

Premorbid functioning versus duration of untreated psychosis in 1 year outcome in first-episode psychosis

OBJECTIVE: This study examines 1year outcome in patients having first-episode non-affective psychosis, with emphasis on Duration of Untreated Psychosis (DUP) and premorbid functioning, in order to clarify how these factors interact. METHOD: Forty-three consecutively admitted patients were all rated on the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning Scale (GAF), both upon hospitalization and at 1year follow-up. In addition, premorbid functioning, DUP, duration of hospitalization, and social functioning were rated. RESULTS: Fifty-six per cent were in remission, 18% suffered multiple relapses and 26% were continuously psychotic at 1 year follow-up. Both poor premorbid functioning and long DUP are significantly correlated with more negative symptoms and poorer global functioning at follow-up. Long DUP is also significantly correlated with more positive symptoms. Even when we control for other factors, including premorbid functioning and gender, DUP is a strong predictor of outcome. To a limited degree premorbid functioning and DUP interact, but DUP has an independent influence on outcome. CONCLUSIONS: these findings strengthen the rationale for establishing health service programs for early detection and treatment of first-onset psychosis     

Influence of duration of untreated psychosis on auditory P300 in drug-naive and first-episode schizophrenia

P300 amplitude reduction in schizophrenia is, according to previous studies, partially recovered by treatment with neuroleptics. However, whether this medication-induced P300 recovery is associated with duration of untreated psychosis (DUP) remains unreported; the present study is a preliminary examination of this question. Auditory P300 was recorded from 18 drug-naive and first-episode schizophrenia patients, among whom 10 were identified as short DUP, and eight as long DUP. Follow-up event-related potential tests were carried out after treatment with haloperidol or bromperidol for approximately 2 months. Recovery of P300 amplitude was replicated after neuroleptic medication was administered. A significant interaction was found between DUP and the medication effect in P300 amplitude over the left temporo-parietal area; a significant P300 recovery was seen in short DUP but not in long DUP. These results suggest that first-episode schizophrenia patients with long DUP might have severe impairments in the left temporal structures, supporting DUP as a key variable in future neurobiological studies of first-episode schizophrenia.     

Determinants of subjective quality of life in first-episode schizophrenia: perspective from Malaysia

Aim: This study sought to examine the determinants of subjective quality of life among patients with first-episode schizophrenia in a developing country. Method: One-hundred and twenty patients registered with National Mental Health Registry for Schizophrenia from 1 January 2003 to 31 August 2005 were included. They were diagnosed with first-episode schizophrenia, schizoaffective and schizophreniform disorders and had been compliant to treatment. Sociodemographic data were obtained and the Brief Psychiatric Rating Scale-Anchored Version, Health of The Nation Outcome Scales, Simpson–Angus Extrapyramidal Side Effects Scale, Barnes Akathisia Scale and the World Health Organization Quality of Life were used to assess psychopathology, side effects from antipsychotics and subjective quality of life. Results: Gender, positive and disorganized symptoms of schizophrenia, and cognitive and physical impairments appeared to be the most important predictors of subjective quality of life among the patients from this centre in Malaysia. Conclusion: Different domains of self-rated quality of life correlated with different sociodemographic and clinical characteristics. Some of the characteristics were malleable and a better understanding of these could lead to improvements in the management of patients with schizophrenia.     

Impact of duration of untreated psychosis on pre-treatment, baseline, and outcome characteristics in an epidemiological first-episode psychosis cohort

INTRODUCTION: To assess the impact of duration of untreated psychosis (DUP) on baseline and 18-month follow-up characteristics controlling for relevant confounders in an epidemiological first-episode psychosis (FEP) cohort. METHOD: The Early Psychosis Prevention and Intervention Centre (EPPIC) in Australia admitted 786 FEP patients from January 1998 to December 2000. Data were collected from medical files using a standardized questionnaire. Data from 636 patients were analyzed. RESULTS: Median DUP was 8.7 weeks. Longer DUP was associated with worse premorbid functioning (p<0.001), higher rate of schizophrenia-spectrum disorders (p<0.001), and younger age at onset of psychosis (p=0.004). Longer DUP was not associated with baseline variables but with a lower rate of remission of positive symptoms (p<0.001) and employment/occupation (p<0.001), a higher rate of persistent substance use (p=0.015), worse illness severity (p<0.001) and global functioning (p<0.001) at follow-up after controlling for relevant confounders, explaining approximately 5% of variance of remission of positive symptoms (p<0.001) in the total sample and 3% in schizophrenia-spectrum disorders excluding bipolar I disorder (p=0.002). Outcome was significantly worse when DUP exceeded 1-3 months. CONCLUSION: Avoiding pitfalls of non-epidemiological studies, DUP appears to be a modest independent predictor of prognosis in the medium-term. Results support the need for assertive early detection strategies.     

Living situation,subjective quality of life and social network among individuals with schizophrenia living in community settings

OBJECTIVE: To investigate the relationships between characteristics of the living situation in the community and subjective quality of life and social network among community-based individuals with schizophrenia. METHOD: A total of 418 individuals with schizophrenia from 10 sites were interviewed with regard to quality of life, psychopathology, social network and needs for care. Characteristics of the living situation investigated were: living alone or not, living with family or not, and having an independent or a sheltered housing situation. RESULTS: An independent housing situation was related to a better quality of life concerning living situation and living with the family to a better quality of life concerning family relations. An independent housing situation was associated with a better social network regarding availability and adequacy of emotional relations. CONCLUSION: People with schizophrenia with an independent housing situation have a better quality of life associated with more favorable perceptions of independence, influence, and privacy. Their social network is better irrespective of whether they live alone or not, or with family or not.     

Cognitive deterioration and duration of untreated psychosis

Aim: To examine the relationship between cognitive deterioration and the duration of untreated psychosis (DUP) in a first‐episode psychosis sample. Method: We assessed a consecutive sample of first‐episode psychosis participants (N = 50) with measures of cognitive deterioration and DUP. Results: Using correlations and stepwise linear regressions, we found strong relationships between DUP and measures of cognitive deterioration. Conclusions: The length of DUP predicted cognitive deterioration. These results highlight a potential DUP grace period (>6 months) in which significant cognitive deterioration may be averted.     

精神分裂症首次发病患者未治期的影响因素分析

目的：探讨首发精神分裂症患者未治期（ DUP）的影响因素。方法：采用一般资料调查表、阳性与阴性症状量表（ PANSS）、诺丁汉起病症状量表（ NOS）以及疾病家庭负担量表（ FBS）对206例首次发病精神分裂症患者的疾病严重程度、起病形式以及因疾病给家庭带来的负担进行评估。结果：首发精神分裂症患者DUP的中位数为6（2,12）个月,其中男性5（1,12）个月,女性7（2,12）个月,男女比率差异无统计学意义（P>0.05）。将患者分为短DUP组（DUP≤6个月）112例和长DUP组（DUP>6个月）94例比较结果显示,不同DUP组的起病形式（χ2=61.99,P=0.000）、家属对患者的关心程度（t=4.09,P=0.000）、疾病对家庭娱乐活动的影响（t=-2.22,P=0.03）以及疾病对家庭成员心理健康的影响（t=-2.53,P=0.01）两组间存在统计学意义。Logistic 回归分析发现,起病形式（ OR =11.46,95%CI =5.70~23.04）是DUP的危险因素;家属对患者的关心程度（OR=0.73,95%CI=0.60~0.90）是DUP的保护性因素。结论：影响首发精神分裂症患者DUP的因素是多方面的,但起病形式及家属对患者的关心程度是主要因素。     

Outcome study of first-episode schizophrenia in a developing country: quality of life and antipsychotics

Aim  Quality of life has recently been emphasized in the management of schizophrenia, yet data from developing country is lacking. We explored the differences in subjective quality of life between conventional antipsychotics (CAs) and atypical antipsychotics (AAs). Methods  This is a naturalistic study conducted in Kuala Lumpur, Malaysia. Patients with first-episode schizophrenia and related psychosis were recruited from Kuala Lumpur Hospital. WHOQOL-BREF, side effects of medications and other variables were assessed after 1 year of treatment in routine clinical situation. Results  The study comprised 120 adults. There were no significant statistical differences between groups concerning subjective quality of life, extrapyramidal side effects and employment. Significant less benzhexol usage was reported among AAs (P < 0.001) compared to CAs and sulpiride. Conclusion  Patients treated with CAs, sulpiride or AAs experienced similar quality of life, clinical and health outcomes after 1 year commencing treatment. Overall, the results are in line with other major pragmatic clinical trials. This study also found sulpiride cost-effective.

Duration of untreated psychosis and pathways to psychiatric services in first-episode schizophrenia

The aim of the present study was to examine the duration of untreated psychosis (DUP) in first-episode schizophrenia patients in Japan and to investigate the available pathways to psychiatric services. Eighty-three patients who visited Keio University Hospital (n = 54) or Oizumi Mental Hospital (n = 29) were evaluated retrospectively with regard to their DUP, living situation, social participation level, referral pathway, reason for seeking treatment, and their global assessment of functioning (GAF) score. The mean DUP was 13.7 months (median, 5.0 months) overall. No significant difference in DUP was found between subjects living alone and those living with others; however, employed patients had a significantly shorter DUP (8.1 months) than unemployed patients (18.7 months). Pathways to psychiatric services were totally different between the two institutions. Fifty-two subjects (62.7%) came to the services directly: 40 patients (74.1%) came to the university hospital and 12 patients (41.4%) came to the mental hospital. At the mental hospital, nine patients (31.0%) had been admitted because of a legal obligation, and six (20.7%) had been referred through public health centers. None of the patients had been referred to either of the services by general practitioners. The main reason for seeking treatment was psychiatric symptom aggravation (59.3%) at the university hospital and acting out (64.3%) at the mental hospital. Some universal psychosocial factors appear to influence the DUP but the characteristics of specific psychiatric services may also affect treatment delays.

目的：调查缓解期偏执型精神分裂症患者的生活质量。方法：采用生活质量综合评定问卷（CQOLI-74）、简明精神病评定量表（BPRS）和治疗中出现的症状量表（TESS）了解患者的生活质量、精神状态、药物不良反应对生活质量的影响。结果：患者组的生活质量总分、躯体功能、心理功能、社会功能明显低于对照组，并涉及到心身健康的多个方面。BPRS分与生活质量呈负相关。结论：缓解期偏执型精神分裂症患者的生活质量明显低于正常人群。     

Self-determination and first-episode psychosis: associations with symptomatology, social and vocational functioning, and quality of life

Self-determination theory (SDT) postulates that satisfaction of three basic psychological needs (i.e., autonomy, competence, and well-being) promotes motivation, well-being, and growth across domains of functioning. Thus, per SDT, we examined satisfaction of basic psychological needs among individuals with first-episode psychosis. First, we quantified the level of need satisfaction among a sample of individuals with first-episode psychosis and compared their level of need satisfaction to that of individuals without psychosis. Second, we examined the association between need satisfaction and several domains of well-being among individuals with first-episode psychosis (i.e., symptomatology, social/vocational functioning, and quality of life). Our results indicated that individuals with first-episode psychosis experience less satisfaction of basic psychological needs as compared to their same-aged counterparts. There was a modest association between need satisfaction and well-being among individuals with first-episode, with the need of relatedness being the need most frequently associated with indices of well-being. Although modest in scope, the results of the current study raise the possibility that further investigation of SDT among individuals with first-episode psychosis may reveal important strategies through which early intervention services can better promote well-being and recovery.
