Reduced awareness of illness in first-episode psychosis

Measurement Based Care in a first episode psychosis program: Development of an algorithm of care based on the Clinical Global Impressions Scale

INTRODUCTION

Adherence to therapeutic guidelines in psychiatry is anchored and facilitated by rating scales. However, they are rarely used in routine care, particularly for psychotic disorders. Consequently, adherence to treatment guidelines are not ideal and patient outcomes are often sub-optimal. In this study, we used the clinician-rated Clinical Global Impressions Scale (CGI) to implement a measurement-based care (MBC) approach and derive indices of quality of care at a first episode psychosis (FEP) program.

METHODS

At the individual level, an algorithm was created using CGI scores and their changes over time to define the concept of Patient Requiring Clinical Attention (PRCA) that encompasses several categories (e.g. episode of severity, treatment inertia, or treatment resistance). At the service level, CGI scores were used to derive several indices of quality of care: severity of illness and its change over time, conformity to the use of low doses of antipsychotic medications, and clozapine offer index.

RESULTS

135 Patients were included in this study of whom 19 patients were identified as PRCA. Of these, 12 (63%) received timely medication, and 7 (37%) were suspected cases of therapeutic inertia. Additionally, 15 patients met criteria for treatment resistance of whom 7 were offered clozapine (47%). At the service level, the average CGI improved by 2 points from baseline to month 1 and average doses of antipsychotic medications prescribed were in line with prescription guidelines for FEP patients.

CONCLUSION

The proposed CGI-based treatment algorithm and service evaluation strategy can help to optimize quality care and services for patients.

Pragmatic implementation of the Clinical Global Impression Scale of Severity as a tool for measurement-based care in a first-episode psychosis program

INTRODUCTION

Measurement-based care (MBC) is an evidence-based practice wherein clinical decisions are informed by patient data collected throughout treatment. MBC has yielded superior patient outcomes compared to standard care. However, the implementation of MBC in the day-to-day practice, particularly in psychotic disorders, poses several challenges. This study evaluates the clinician-rated Clinical Global Impressions Scale of Severity (CGI-S), for MBC implementation at a first-episode psychosis program.

METHODS

The CGI-S was evaluated in the context of routine care on fidelity to practice, inter-rater reliability among psychiatrists and concurrent validity with scales measuring different domains of psychopathology (SAPS, SANS, GAF, BPRS, PANSS-6).

RESULTS

A high fidelity to practice (67%) and inter-rater reliability was found (r_wg = 0.92). CGI-S correlations were significant and strongest with BPRS (r = 0.55; p < 0.01), GAF (r = 0.53; p < 0.01), SAPS (r = 0.52, p < 0.01), and PANSS-6 (r = 0.41; p < 0.05) scores. However, correlations with SANS and PANSS-6 Negative sub-scale were weak.

CONCLUSION

Findings suggest the CGI may be used to overcome important barriers towards MBC implementation within the context of first episode psychosis. However, as suggested by data, further improvements in capturing negative symptoms by rating clinicians are needed.

Estimated Proportions and Characteristics of National Survey Respondents Reporting New Diagnoses of Schizophrenia or Other Psychoses in the Past Year as Compared With Prior Years

Epidemiologic data on first-episode psychosis is limited due to the infrequency of cases in the general population. This study uses the National Epidemiologic Survey on Alcohol and Related Conditions-III (N = 36,309) to examine population-based estimates of early psychosis based on adults who report a first-time diagnosis of schizophrenia from a doctor in the past year and compares them with those receiving diagnoses in previous years. Altogether, 60 respondents reported past-year schizophrenia (170 per 100,000) or 6.7% of 901 with any reported schizophrenia. Mean age was 41.4 ± 2.1, and they reported significantly higher rates of any past-year substance use disorder (44.7%) than individuals diagnosed in previous years (27.7%), specifically alcohol use disorder. Compared with other samples (many of which excluded older adults), this study suggests that early psychosis may affect older populations more than previously recognized, but comorbidity with substance use disorders showed similar elevations.

Evaluation of the association between insight and symptoms in a large sample of patients with schizophrenia

Background

The objective of the present study was to examine the association of insight into the illness with demographic variables and symptomatology in a sample of 1213 patients with schizophrenia.

Method

Data were collected with the Psychosis Evaluation tool for Common use by Caregivers (PECC), a semi-structured interview evaluating five symptom domains of schizophrenia and the insight items ‘awareness of having a mental disorder’ and ‘attributing symptoms to a mental disorder’.

Results

Insight was positively associated with educational level and inversely with overall symptom severity, and the positive, negative, excitatory and cognitive symptom domains. At symptom level, the items ‘delusions’, ‘grandiosity’, ‘poor rapport’, ‘social withdrawal’ and ‘guilt feelings’ showed the strongest associations with both insight items. Overall, correlations between insight and symptomatology were modest, explaining less than 30% of the variance in insight.

Conclusion

Lack of insight in schizophrenia is partially explained by clinical symptoms and demographic measures.

"We all have a responsibility": a narrative discourse analysis of an information campaign targeting help-seeking in first episode psychosis

BACKGROUND

Intervening at an early stage of psychosis improves the chances of recovery from first-episode psychosis. However, people who are experiencing distress and early psychotic symptoms generally seem to delay seeking help. Therefore, multifaced information campaigns targeting help-seeking behavior of potential patients and their network are considered important tools within early detection and intervention strategies. In this study, we aimed to explore which discursive meaning content, including roles and actors, such information campaigns build on and construct. Our intention was not to provide objective answers, but to contribute to a discursive debate about potential conflicts in messages conveyed in such campaigns.

METHODS

A broad sample of information material utilized by TIPS Stavanger University Hospital (Norway) was examined. The material consisted of posters, booklets and brochures, newspaper ads, Facebook ads, and TIPS Info's website, representing various campaigns from 1996 to April 2018. A narrative discursive approach was applied at an epistemological level. At a practical level, a team-based thematic analysis was utilized to identify patterns across data.

RESULTS

Diversity and several changes in strategy were recognized throughout the information material. Furthermore, three main themes and four subthemes were found to constitute the meaning content built in the information campaigns: knowledge is key; (almost) an illness among illnesses; and we all have a responsibility (comprising of the subthemes; to respond quickly; to step in; to provide an answer; and to tag along).

CONCLUSION

Our findings pointed to common dilemmas in mental health services: How to combine professional expert knowledge with collaborative practices that emphasize shared decision-making and active roles on behalf of patients? How to combine a focus on symptoms and illness and simultaneously express the importance of addressing patients' recourses? And how can we ask for societal responsibility in help-seeking when professionals are placed in expert positions which may not be optimal for dialogue with potential patients or their network? We discuss whether highlighting practices with more weight on resources and active roles for patients and their surroundings in information campaigns could promote earlier help-seeking.

Cognitive capacity similarly predicts insight into symptoms in first- and multiple-episode psychosis

BACKGROUND

Lack of insight is a frequent characteristic of psychotic disorders, both in patients who recently experienced a first episode of psychosis (FEP) and those who experience recurrent multiple episodes (MEP). Insight is a multifaceted construct: its clinical form notably includes the unawareness of being ill, of symptoms, and of the need for treatment. Cognitive capacity is among the key determinants of insight into symptoms, but less is known about whether stage of illness (FEP vs. MEP) moderates this association.

METHODS

Our aim is to evaluate the association between cognitive capacity and symptom unawareness using structural equation modeling and moderated multiple regression. A total of 193 FEP and MEP patients were assessed using the CogState battery and the Scale to Assess Unawareness of Mental Disorder.

RESULTS

Analyses suggest that cognitive capacity accounts for a relatively small proportion of the total variation in symptom unawareness (6.4%). There was no evidence to suggest a moderating effect of stage of illness on this association.

CONCLUSIONS

The effect of general cognitive capacity on symptom unawareness is relatively small, and this basic relation was unrelated to stage of illness. It is possible that stage of illness could moderate this association only for certain facets of insight not assessed in this study (e.g., unawareness of the need for treatment).

Dimensions of insight in schizophrenia: Exploratory factor analysis of items from multiple self- and interviewer-rated measures of insight

OBJECTIVE

Insight in schizophrenia is regarded as a multidimensional construct that comprises aspects such as awareness of the disorder and recognition of the need for treatment. The proposed number of underlying dimensions of insight is variable in the literature. In an effort to identify a range of existing dimensions of insight, we conducted a factor analysis on combined items from multiple measures of insight.

METHOD

We recruited 165 participants with enduring schizophrenia (treated for >3years). Exploratory factor analysis was conducted on itemized scores from two interviewer-rated measures of insight: the Schedule for the Assessment of Insight-Expanded and the abbreviated Scale to assess Unawareness of Mental Disorder; and two self-report measures: the Birchwood Insight Scale and the Beck Cognitive Insight Scale.

RESULTS

A five-factor solution was selected as the best-fitting model, with the following dimensions of insight: 1) awareness of illness and the need for treatment; 2) awareness and attribution of symptoms and consequences; 3) self-certainty; 4) self-reflectiveness for objectivity and fallibility; and 5) self-reflectiveness for errors in reasoning and openness to feedback.

CONCLUSIONS

Insight in schizophrenia is a multidimensional construct comprised of distinct clinical and cognitive domains of awareness. Multiple measures of insight, both clinician- and self-rated, are needed to capture all of the existing dimensions of insight. Future exploration of associations between the various dimensions and their potential determinants will facilitate the development of clinically useful models of insight and effective interventions to improve outcome.

Comparison of insight and clinical variables in homeless and non-homeless psychiatric inpatients in China

There are no published data on insight in homeless patients with psychiatric disorders in China. This study examined insight in homeless and non-homeless Chinese psychiatric inpatients in relation to demographic and clinical variables. A total of 278 homeless and 222 non-homeless inpatients matched in age and gender were included in the study. Demographic and clinical characteristics were collected based on a review of medical charts and a clinical interview with standardized instruments. Insight was evaluated with the Insight and Treatment Attitudes Questionnaire. Altogether 20.5% of homeless inpatients and 43.7% of the non-homeless controls had good insight. Compared with homeless inpatients with impaired insight, homeless inpatients with good insight had higher physical quality of life, longer duration of illness and less severe positive and negative symptoms. Impaired insight appeared more common in homeless psychiatric inpatients in China. Further studies should address the need for effective therapeutic interventions that promote homeless patients' insight.

Factors Associated with Timely Physician Follow-up after a First Diagnosis of Psychotic Disorder

OBJECTIVE

Physician follow-up after a first diagnosis of psychotic disorder is crucial for improving treatment engagement. We examined the factors associated with physician follow-up within 30 days of a first diagnosis of schizophrenia.

METHOD

We conducted a retrospective cohort study using linked health administrative data to identify incident cases of schizophrenia between 1999 and 2008 among people aged 14 to 35 years in Ontario. We estimated the proportion of patients who had physician follow-up within 30 days of the index diagnosis. We used multilevel logistic regression models to examine the factors associated with any physician follow-up and follow-up by a psychiatrist.

RESULTS

We identified 20,096 people with a first diagnosis of schizophrenia. Approximately 40% of people did not receive any physician follow-up within 30 days, and nearly 60% did not receive follow-up by a psychiatrist. Males had lower odds of receiving any physician follow-up, and the odds of psychiatrist follow-up decreased with increasing age and were lower for those living in rural areas. Both prior contact with a general practitioner for a mental health reason and prior contact with a psychiatrist were strongly associated with higher odds of receiving both types of follow-up.

CONCLUSIONS

Many people do not have any physician contact within 30 days of the first diagnosis of schizophrenia, and patients without prior engagement with mental health services are at highest risk. We need information on the reasons behind this lack of physician follow-up to inform strategies aimed at improving engagement with services during the early stages of psychosis.

Insight as a social identity process in the evolution of psychosocial functioning in the early phase of psychosis

BACKGROUND

Awareness of illness (insight) has been found to have contradictory effects for different functional outcomes after the early course of psychosis. Whereas it is related to psychotic symptom reduction and medication adherence, it is also associated with increased depressive symptoms. In this line, the specific effects of insight on the evolution of functioning over time have not been identified, and social indicators, such as socio-occupational functioning have barely been considered. Drawing from social identity theory we investigated the impact of insight on the development of psychosocial outcomes and the interactions of these variables over time.

METHOD

The participants, 240 patients in early phase of psychosis from the Treatment and Early Intervention in Psychosis Program (TIPP) of the University Hospital of Lausanne, Switzerland, were assessed at eight time points over 3 years. Cross-lagged panel analyses and multilevel analyses were conducted on socio-occupational and general functioning [Social and Occupational Functioning Assessment Scale (SOFAS) and Global Assessment of Functioning (GAF)] with insight, time and depressive symptoms as independent variables.

RESULTS

Results from multilevel analyses point to an overall positive impact of insight on psychosocial functioning, which increases over time. Yet the cross-lagged panel analysis did not reveal a systematic positive and causal effect of insight on SOFAS and GAF scores. Depressive symptoms seem only to be relevant in the beginning of the treatment process.

CONCLUSIONS

Our results point to a complex process in which the positive impact of insight on psychosocial functioning increases over time, even when considering depressive symptoms. Future studies and treatment approaches should consider the procedural aspect of insight.

Effects of antipsychotics on insight in schizophrenia: results from independent samples of first-episode and acutely relapsed patients

We aimed to investigate whether antipsychotics differentially impact insight and whether these effects appear because of improvement in psychopathological manifestation in 132 first-episode schizophrenia patients and 201 acutely relapsed schizophrenic patients, who were followed up for 12 weeks. Olanzapine and risperidone were administered to first-episode schizophrenia patients, whereas acutely relapsed schizophrenic patients were treated with olanzapine, perazine and ziprasidone. The Positive And Negative Syndrome Scale (PANSS) was used to assess psychopathology. Insight was assessed using the G12 item of PANSS. Unadjusted mixed-model regression analysis indicated a significant improvement in the PANSS G12 item score in both groups. There were no significant differences between distinct treatment subgroups of patients in terms of improvement in the PANSS G12 item score. After adjustment for the trajectories of changes in symptom dimensions, a decrease in the PANSS G12 item score was because of an improvement in positive, negative and excitement symptoms. A decrease in the PANSS G12 item score was also related to an increase in the severity of depressive symptomatology. Our results indicate that antipsychotics exert similar effects on insight in acute psychosis. These effects are likely because of an improvement in psychopathological manifestation. The improvement in insight might be related to the development of depressive symptoms.

Metacognitive capacity as a predictor of insight in first-episode psychosis

Impaired insight is common in the first episode of psychosis (FEP). Although considerable research has examined the factors that are associated with impaired insight in chronic psychosis, less is known about the factors that underlie and sustain poor insight in FEP. Impaired metacognition, or the ability to form integrated representations of self and others, is a promising potential contributor to poor insight in FEP. To explore this possibility, the authors assessed insight and metacognition in 40 individuals with FEP and then examined the relationship between these areas and social cognition domains, neurocognitive domains, and psychotic symptoms. Correlation analyses revealed that improved insight was associated with higher metacognition, better vocabulary and Theory of Mind scores, and fewer symptoms. The domain of metacognitive mastery also predicted clinical insight. Results support the need to develop an integrative therapeutic approach focused on improving metacognition, hence addressing poor insight in FEP.

The effects of aging on insight into illness in schizophrenia: a review

OBJECTIVES

Impaired insight into illness is a prevalent feature of schizophrenia, which negatively influences treatment adherence and clinical outcomes. Little is known about the effects of aging on insight impairment. We aimed to review the available research literature on the effects of aging on insight into illness in schizophrenia, in relation to positive, negative, and cognitive symptoms. Ultimately, we propose a trajectory of insight in schizophrenia across the lifespan.

METHOD

A systematic Medline® literature search was conducted, searching for English language studies describing the relationship of insight into illness in schizophrenia with aging.

RESULTS

We identified 62 studies. Insight impairment is associated with illness severity, premorbid intellectual function (i.e. IQ), executive function, and memory. Insight impairment improves modestly during midlife, worsening again in late life. It tends to fluctuate with each episode of psychosis, likely in relation to worsening positive symptoms that improve with antipsychotic treatment. The relationship between insight impairment and cognitive dysfunction appears to attenuate with age, while the relationship with lower premorbid intellectual function is preserved. The association between impaired insight and negative symptoms is unclear.

CONCLUSIONS

The available literature suggests that the course of insight impairment follows a U-shaped curve, where insight impairment is severe during the first episode of psychosis, modestly improves over midlife, and declines again in late life. Future studies are required to investigate the trajectory of insight into illness and its core domains across the lifespan from prodromal phase to late life.

A multi-dimensional approach to insight and its evolution in first-episode psychosis: a 1-year outcome naturalistic study

The aim of the study was to describe the evolution of the different dimensions of insight at 1 year and its associations with psychopathology and symptomatic remission. Participants included 55 patients hospitalized for a first psychosis episode and followed up at 6 and 12 months after discharge. Measures included the Scale to Assess Unawareness of Mental Disorder and the Positive and Negative Syndrome Scale (PANSS). Six dimensions of insight were evaluated, for current episode at hospital discharge and at 6 and 12 month FUs and past episode (at 6 and 12 month follow-ups). Our results show that concerning the current episode, only awareness of the social consequences and of the positive symptoms significantly improved during follow-up. Insight into the past episode improved for awareness of having a mental disorder, the social consequences and the positive symptoms of mental illness. Cross-sectional associations between insight and PANSS show weak to moderate, albeit significant, associations. Most of the dimensions of insight are positively and significantly associated with remission. Our findings suggest that the main underlying dimensions of insight evolve differently over time, which could suggest different inherent processes. This could be useful for developing psychotherapeutic programmes acting upon the different aspects of insight.

The nature and evolution of insight in schizophrenia: a multi-informant longitudinal study of first-episode versus chronic patients

BACKGROUND AND AIMS

This study investigated a novel distinction between two possible sources of poor insight in schizophrenia: primary unawareness, in which the ill person is not aware that other people think one has a problem, and secondary unawareness (or disagreement), in which a person does appreciate that other people think one has a problem. A secondary goal was to compare the evolution of insight in first-episode and chronic schizophrenia.

METHODS

Sixty-eight first-episode and 51 chronic patients were administered two versions of the Scale of Unawareness of Mental Disorder (SUMD) at three time points: hospital admission, discharge, and 6-month post-discharge. In the first standard SUMD version, they were asked about their own opinions, whereas in the second modified version, they were asked about their best guess of their doctor's opinion.

RESULTS

While overall level of unawareness remained stable within each single episode, there were significant Type of Unawareness (primary versus secondary) by Clinical Status (admission versus discharge versus 6-month post-discharge) and Type of Unawareness by Phase of Illness (first-episode versus chronic) interaction effects. More specifically, in the first-episode group, primary unawareness steadily decreased over time. In contrast, in the chronic group, primary unawareness decreased markedly during hospitalization and returned to baseline after discharge.

CONCLUSIONS

These results provide preliminary support for the notion that impaired insight is an additive outcome of primary unawareness and disagreement, and that change in insight over time occurs mostly at the level of their relative proportion as opposed to their overall sum. Implications for studying and treating poor insight in schizophrenia are discussed.

Psychometric properties of the abbreviated version of the Scale to Assess Unawareness in Mental Disorder in schizophrenia

BACKGROUND

The Scale to Assess Unawareness in Mental Disorder (SUMD) is widely used in clinical trials and epidemiological studies but more rarely in clinical practice because of its length (74 items). In clinical practice, it is necessary to provide shorter instruments. The aim of this study was to investigate the validity and reliability of the abbreviated version of the SUMD.

DESIGN

We used data from four cross-sectional studies conducted in several psychiatric hospitals in France.

INCLUSION CRITERIA

a diagnosis of schizophrenia based on DSM-IV criteria.

DATA COLLECTION

socio-demographic and clinical data (including duration of illness, Positive and Negative Syndrome Scale, and the Calgary Depression Scale); quality of life; SUMD.

STATISTICAL ANALYSIS

confirmatory factor analyses, item-dimension correlations, Cronbach's alpha coefficients, Rasch statistics, relationships between the SUMD and other parameters. We tested two different scoring models and considered the response 'not applicable' as '0' or as missing data.

RESULTS

Five hundred and thirty-one patients participated in this study. The 3-factor structure of the SUMD (awareness of the disease, consequences and need for treatment; awareness of positive symptoms; and awareness of negative symptoms) was confirmed using LISREL confirmatory factor analysis for the two models. Internal item consistency and reliability were satisfactory for all dimensions. External validity testing revealed that dimension scores correlated significantly with all PANSS scores, especially with the G12 item (lack of judgement and awareness). Significant associations with age, disease duration, education level, and living arrangements showed good discriminant validity.

CONCLUSION

The abbreviated version of the SUMD appears to be a valid and reliable instrument for measuring insight in patients with schizophrenia and may be used by clinicians to accurately assess insight in clinical settings.

Systematic review reveals heterogeneity in the use of the Scale to Assess Unawareness of Mental Disorder (SUMD)

The Scale to Assess Unawareness of Mental Disorder (SUMD) is one of the most widely used instruments to measure insight into mental disorders. The aim of this study was to review all studies using the SUMD in the last 20 years. We performed an electronic search of MEDLINE using PubMed to identify all relevant studies published from 1993 to 2012. The following data were extracted from each article: characteristics of the SUMD (version, rating scale, scoring, and item/dimension used), methodological aspects (country, language, subject inclusion criteria, and sample size), and statistical methods to analyse insight. Of the 133 articles screened, 100 studies were included in the review. Fifty-two studies were published over the past five years. The SUMD was rarely used in its entirety, and the use of selected items or subscales was heterogeneous across studies. The studies also varied in terms of response modalities and in the use of 3- or 5-point Likert scales. The calculation of insight scores was highly variable and included the following: treating items as categorical or continuous variables, separate analysis of individual items, items expressed in terms of the sum total or the mean scores, and a range of score values used to define insight. This paper provides a systematic review of studies using the SUMD and reveals important differences in the versions used, the methods of calculation, and the interpretation of scores across studies. The use of a modified SUMD may compromise the psychometric properties of the scale, lead to erroneous conclusions, and prevents comparison of results across studies. Our review underlines the need for the standardised use of the SUMD.

Lack of Insight in Psychosis: Theoretical Concepts and Clinical Aspects

Background: Different theories concerning pathways to insight have been proposed which underpin the numerous assessment measures. Cognitive behavioural therapy (CBT) is one treatment approach that has been used to improve insight. Aims: The aim of this review was to promote a greater focus on developing effective CBT strategies to ameliorate insight in psychosis through the exploration of the concept of insight in psychosis and evaluation of research in the area. Method: A comprehensive search and review of published studies examining the impact of CBT on insight in psychosis was conducted. We searched the databases PubMed, Medline, PsychInfo, the Psychology and Behavioral Sciences Database, and CINAHL with limits set to 10 years, humans, and English language. We hand-searched reference lists of major studies on insight, and theoretical review papers. We filtered our results according to relevance and chose 50 papers for final consideration. Results: The multidimensionality of insight is reflected in the variety of different insight measures in clinical use. Research findings on the impact of CBT on insight are conflicting. Cognitive insight and clinical insight appear to be different concepts that are not fully captured by existing measurement scales. Conclusions: The conflicting results found in research examining the impact of CBT on insight may be partially explained by the different theories underpinning insight in psychosis communicated through psychoeducation in CBT. Furthermore, the use of more than one insight assessment measure may capture the complexity of insight more effectively. Qualitative research with service users would enrich the knowledge in this area.

Association of grey matter volume deviation with insight impairment in first-episode affective and non-affective psychosis

The neurobiological correlates of impaired insight in psychotic illness remain uncertain and may be confounded by factors such as illness progression and medication use. Our study consisted of two separate experiments. In the first experiment, we examined the association between measures of insight and regional brain volume in thirty-two patients with first-episode psychosis. In the second experiment, we looked at similar associations in thirty individuals with chronic schizophrenia. Detailed measures of symptom awareness and symptom attribution were obtained using the Scale to assess Unawareness of Mental Disorder. MRI scans were acquired and analysed using Statistical Non-Parametric Mapping for voxel-based analyses of grey matter maps. Regression models were used to assess the relationship between insight and grey matter volume in both the first-episode psychosis and the chronic schizophrenia experiments whilst controlling for potential confounds. In first-episode psychosis patients, symptom misattribution was associated with increased grey matter in the right and left caudate, right thalamus, left insula, putamen and cerebellum. In the chronic schizophrenia study, there were no significant associations between regional grey matter volume and measures of insight. These findings suggest that neuroplastic changes within subcortical and frontotemporal regions are associated with impaired insight in individuals during their first episode of psychosis.

Dropout rate and associated factors in patients with bipolar disorders

OBJECTIVES

Effective, long-term therapy for bipolar disorders is a critical goal of mental health care, but achieving this goal is complicated by numerous factors in real clinical settings. The aim of this study was to investigate dropout patterns and their associated factors in patients with bipolar disorders.

METHODS

The study participants were 275 patients with DSM-IV bipolar disorders, receiving planned maintenance treatment among patients at the Mood Disorders Clinic of Seoul National University Bundang Hospital between January 2005 and December 2007. The rates of dropout in patients were prospectively examined for 3 years. The factors affecting the dropouts were analyzed using a Cox regression model.

RESULTS

The dropout rates were 10.9%, 20.4%, 24.7%, 33.8%, 44.0%, and 50.2% at 1, 3, 6, 12, 24, and 36 months after treatment entry, respectively. The dropout rates increased rapidly during the first three months and slowed after 12 months. Past psychotic symptoms (HR 0.523, 95% CI 0.339-0.807), longer illness duration (HR 0.975, 95% CI 0.955-0.966), past psychiatric diagnoses (bipolar disorder, HR 0.242, 95% CI 0.120-0.490; other axis I disorders 0.434, 95% CI 0.268-0.701), and a past history of dropouts (HR 1.746, 95% CI 1.028-2.965) significantly influenced the time to dropout in bipolar patients. The main reasons for dropout were 'denial of therapeutic need' (34.8%) and 'lack of treatment efficacy' (23.2%). Dropout from the maintenance phase of treatment was mainly attributed to the patients' poor understanding of the effects of their treatment.

CONCLUSION

A high early dropout rate for subjects with bipolar disorders was observed in this study, suggesting an increased risk for insufficient maintenance treatment. These results may support the role of psychoeducational approaches in enhancing adherence to treatment, as well as social approaches to improving public awareness. Following the early evaluation of a patient's concept of bipolar disorders, individualized psychoeducational strategies are necessary to improve the long-term outcomes for subjects with bipolar disorders.

Early intervention services for psychosis and time until application for disability income support: a survival analysis

Ensuring the financial security of individuals recovering from first episode psychosis is imperative, but disability income programs can be powerful disincentives to employment, compromising the social and occupational aspects of recovery. Survival analysis and Cox regression analysis were used to examine the rate at which individuals served by early intervention for psychosis (EIP) services apply for government disability income benefits and factors that predict rate of application. Health records for 558 individuals served by EIP programs were reviewed. Within the first year of receiving services 30% will make application for disability income; 60% will do so by 5 years. Rate of application is predicted by rate of hospital admission, financial status and engagement in productivity roles at the time of entry to EIP service. The findings suggest the need to examine the extent to which the recovery goals of EI services are undermined by early application for government income support. They also suggest the need to develop best practice guidelines related to ensuring the economic security of individuals served.

Schizophrenia with preserved insight is associated with increased perfusion of the precuneus

BACKGROUND

Preserved insight into illness has been suggested to be predictive of outcome in patients with schizophrenia. We aimed to investigate the functional substrate underlying preserved insight in these patients.

METHODS

We recruited patients with paranoid schizophrenia and healthy controls matched for age and sex. Patients were grouped according to preserved or impaired insight into illness using the Scale to assess Unawareness of Mental Disorder (SUMD). Whole-brain technetium-99m ethyl cysteinate dimer single photon emission computed tomography regional cerebral blood flow was compared at the voxel level between the 2 groups using a statistical parametric map (voxel-level significance of p < 0.001, uncorrected; cluster level significance of p < 0.05, uncorrected).

RESULTS

We enrolled 31 right-handed patients with schizophrenia and 18 controls in our study. Twenty-one (67.7%) patients had preserved insight. The 2 groups did not differ significantly in demographic and clinical characteristics or in treatment. Compared with controls, the whole group of patients showed bilateral frontotemporal hypoperfusions, with no statistical difference between patients with preserved or impaired insight for these areas. Patients with preserved insight showed significantly increased perfusion of the bilateral precuneus relative to those with impaired insight.

LIMITATIONS

Patients with subtypes other than paranoid schizophrenia have to be investigated to assess whether involvement of the precuneus in patients with preserved insight can be identified across the full spectrum of subtypes and symptoms of schizophrenia. Moreover, our study concerned only the central dimension (awareness of mental disorder) of 1 scale (SUMD); other dimensions of insight could be studied.

CONCLUSION

Our results show that schizophrenia with preserved insight is associated with greater perfusion of the precuneus, a brain area known to be involved in self- consciousness, suggesting a compensatory mechanism of fronto-temporal impairment.

Stigma as a predictor of insight in schizophrenia

Insight in schizophrenia can be seen as a multifactorial phenomenon. Although multifactorial pathways have also been suggested for insight formation, motivational explanations have rarely been tested. The present study explores stigma as one possible determinant of a motivated lack of insight in integrated models of insight formation. It examines the contribution of socio-demographic and clinical variables, neurocognitive functions, symptoms, and stigma to the prediction of insight into illness. Patients diagnosed with schizophrenia spectrum disorders (N=111) participated in a comprehensive battery of instruments to measure insight dimensions, stigma, neurocognitive functions, symptoms, socio-demographic and clinical variables. Blockwise multiple regression analysis indicates significant association of variability in insight dimensions with gender (7%) and stigma (i. e., stereotype agreement: 5%). Our findings demonstrate an incremental validity of stigma, which indicates a motivational pathway of insight formation. This study enables better understanding of the multifactorial nature of insight, which should be considered in therapeutic interventions to improve insight. The roles of gender and neurocognitive functions in insight formation are also discussed.

Insight in schizophrenia-course and predictors during the acute treatment phase of patients suffering from a schizophrenia spectrum disorder

BACKGROUND

To analyse insight of illness during the course of inpatient treatment, and to identify influencing factors and predictors of insight.

METHODS

Insight into illness was examined in 399 patients using the item G12 of the Positive and Negative Syndrome Scale ("lack of insight and judgement"). Ratings of the PANSS, HAMD, UKU, GAF, SOFAS, SWN-K and Kemp's compliance scale were performed and examined regarding their potential association with insight. The item G12 was kept as an ordinal variable to compare insight between subgroups of patients.

RESULTS

Almost 70% of patients had deficits in their insight into illness at admission. A significant improvement of impairments of insight during the treatment (p<0.0001) was observed. At admission more severe positive and negative symptoms, worse functioning and worse adherence were significantly associated with poorer insight. Less depressive symptoms (p=0.0004), less suicidality (p=0.0218), suffering from multiple illness-episodes (p<0.0001) and worse adherence (p=0.0012) at admission were identified to be significant predictors of poor insight at discharge.

CONCLUSION

The revealed predictors might function as treatment targets in order to improve insight and with it outcome of schizophrenia.

Association of insight with sociodemographic and clinical factors, quality of life, and cognition in Chinese patients with schizophrenia

PURPOSE

The aims of this study were to assess insight in Chinese patients with schizophrenia and to identify its relationship with sociodemographic and clinical factors, cognition, and quality of life (QOL).

METHODS

A cohort of 139 patients with clinically stable schizophrenia was selected by consecutively screening patients who had been diagnosed with schizophrenia and who were attending the outpatient department of a university-affiliated psychiatric hospital in China. Participants' sociodemographic and clinical characteristics, including psychotic and depressive symptoms and insight, as well as their social functioning, QOL, and flexibility of cognition, were assessed with standardized rating instruments.

RESULTS

Thirty-three patients (23.7%) had good insight into their illness. In univariate analyses, poor insight was associated with the positive, negative, and general symptom scores of the Positive and Negative Syndrome Scale (PANSS), and with higher scores on the physical and mental components of QOL. In multivariate analysis, poor insight was independently associated with a higher negative symptom score on the PANSS, a shorter length of illness, and with a high score on the physical components of QOL.

CONCLUSIONS

Poor insight is common in patients with clinically stable schizophrenia. In this study, insight was not associated with basic sociodemographic characteristics or had it any associations with depression or the flexibility of cognitive processes.

Insight in Chinese schizophrenia patients: a 12-month follow-up

This study aimed to assess insight in Chinese schizophrenia patients and to identify its relationship with socio-demographic and clinical factors, executive functions and quality of life (QOL). A cohort of 139 clinically stable schizophrenia patients was selected by consecutively screening patients diagnosed with schizophrenia who were attending the outpatient department of a university-affiliated psychiatric hospital in China. Participants' socio-demographic and clinical characteristics, including psychotic symptoms, depression and insight, as well as QOL and executive functions, were periodically assessed with standardized rating instruments. Patients received standard psychiatric care and were followed up for 1 year. Impaired insight was found to be common in stable Chinese schizophrenia patients (76.3%), with merely 5% showing improvement over the 1-year follow-up. Insight was inversely correlated with positive and negative symptoms at all but the 12-month assessment and with both the physical and mental components of QOL at baseline and the 12-month assessment. Insight was not associated with depressive symptoms or executive functions. Standard psychiatric care does not improve the level of insight in clinically stable Chinese schizophrenia outpatients, which warrants the introduction of specific therapeutic interventions that enhance insight.

Insight into illness in patients and caregivers during early psychosis: a pilot study

BACKGROUND

Impaired insight into illness is common during early psychosis and has been associated with treatment delays and poorer long-term outcomes. The relationship between patients' insight into illness and their caregivers' knowledge about psychosis is putatively associated with treatment outcome but there is limited research about this. This pilot study was designed to test the hypothesis that caregivers' levels of insight into illness is associated with patients' insight into illness in early psychosis and would be related to caregivers' levels of critical, rejecting attitudes toward patients.

METHODS

Patients with schizophrenia or schizoaffective disorder within 5 years of psychosis onset (n=14) and caregivers (n=14) of the patients' choosing were studied. Insight into illness was assessed in patients using the Scale to assess Unawareness of Mental Disorder (SUMD). Caregiver insight into illness was assessed with a modified version of the SUMD with questions rephrased to probe caregivers' understanding of the patients' illness. Caregivers' critical attitudes toward patients were assessed with the Patient Rejection Scale (PRS).

RESULTS

Significant correlations were found between patients' and caregivers' awareness of need for treatment (r=.55, p=.02), awareness of symptoms (r=.48, p=.04) and between caregivers' awareness of illness and critical attitudes toward patients (r=.65, p=.01).

CONCLUSIONS

These findings suggest that caregivers' emotional characteristics and levels of insight into illness may be related to insight into illness in patients. Implications for family psychoeducational approaches to impairments of insight into illness during early psychosis are discussed.

Trait and state attributes of insight in first episodes of early-onset schizophrenia and other psychoses: a 2-year longitudinal study

BACKGROUND

Increasing evidence supports the important role of illness state and individual characteristics in insight.

METHODS

Insight, as measured with the Scale to Assess Unawareness of Mental Disorder, over the first 2 years of early-onset first-episode psychosis and its correlations with clinical, socio-demographic, cognitive, and structural brain variables are studied.

RESULTS

(1) insight at 2 years is poorer in schizophrenia spectrum disorders (SSDs) than in subjects with other psychoses; (2) the more severe the psychosis, the worse the insight. In SSD, depressive symptoms, poorer baseline executive functioning, lower IQ, longer duration of untreated psychosis (DUP), and poorer premorbid infancy adjustment are associated with poorer insight; frontal and parietal gray matter (GM) reductions at baseline correlate with worse insight into having psychotic symptoms at 2 years; (3) insight into having a mental disorder (Scale to Assess Unawareness of Mental Disorder [SUMD]1) at 1 year, DUP, and baseline IQ are the most consistent variables explaining different aspects of insight at 2 years in SSD patients. IQ and SUMD1 at 1 year, together with left frontal and parietal GM volumes, explain 80% of the variance of insight into having specific psychotic symptoms in SSD patients (adjusted R(2) = 0.795, F = 15.576, P < .001).

CONCLUSION

Insight is a complex phenomenon that depends both on severity of psychopathology and also on disease and subject characteristics, such as past adjustment, IQ, DUP, cognitive functioning, frontal and parietal GM volumes, and age, gender, and ethnicity.

Premorbid personality and insight in first-episode psychosis

BACKGROUND

Insight in psychosis and schizophrenia is considered a complex biopsychosocial phenomenon. Premorbid personality is regarded by some authors as part of the substrate to many psychiatric phenomena, but it is not clear if this applies to insight.

AIM

To examine longitudinal relationships between personality traits and insight dimensions in first-episode psychosis.

METHODS

One hundred consecutive antipsychotic-naïve first-episode nonaffective psychotic patients admitted to hospital were included in the study. Eighty-one patients completed at 1 month a premorbid personality evaluation, plus baseline, and 6-month insight assessments. We used the Assessment and Documentation of Psychopathology inventory for assessing insight dimensions (not feeling ill, lack of insight, and refusal of treatment) and the Personality Assessment Schedule for ascertaining 5 dimensions of premorbid personality (schizoid, passive-dependent, anancastic, sociopathic, and schizotypy).

RESULTS

At baseline, personality dimensions did not show any association with insight dimensions, with the exception of schizotypy traits. At 6 months, schizoid and sociopathic personality showed a significant association with not feeling ill (r = .30, P ≤ .007; r = .27, P = .01) and lack of insight (r = .36, P = .001; r = .41, P < .001), respectively. When we calculated insight change, schizoid and sociopathic personality had moderate correlation with the lack of insight dimension (r = -.34, P = .002; r = .38, P < .001, respectively). After applying partial correlations for potential confounders and Bonferroni correction, the associations remained significant. Moreover, using a regression model, sociopathic and schizoid personality significantly predicted lack of insight at 6 months and change from baseline to the 6 months assessment.

CONCLUSIONS

Sociopathic and schizoid personality dimensions were not only significantly associated with lack of insight at 6 months but also predicted change on lack of insight over 6 months. Therefore, exploring premorbid personality traits at the beginning of a psychotic episode may be helpful in identifying patients at high risk for lack of insight during the initial course of the illness.

Insight: demographic differences and associations with one-year outcome in schizophrenia and schizoaffective disorder

BACKGROUND

Insight is increasingly seen as an important variable for study in psychotic illness, particularly in relation to treatment adherence. This study aims to quantify the association of insight with outcome, sociodemographic variables and diagnosis in a large stable patient sample.

METHOD

Data are from a one-year, open-label, international, multicenter trial (n=670) of long-acting risperidone in adult symptomatically stable patients with schizophrenia or schizoaffective disorder. Psychopathology and insight were quantified using the Positive and Negative Syndrome Scale (PANSS). Patients were assessed at four time points over the year of the study.

RESULTS

31.2% of the sample showed clinically significant deficits in insight at baseline. There were no differences based on sex, but significant differences in age and diagnosis, with oldest patients and schizophrenia patients (cf., schizoaffective disorder) showing more deficits. Baseline insight impairment was correlated with change in PANSS score at one year (r=-0.243, p<0.001). Recursive partitioning showed that, of those whose symptoms improved, those whose insight also improved were more likely to complete the trial.

CONCLUSIONS

Insight is important above and beyond the effects of symptoms for predicting continuation in drug trials. This may have implications for the design and analysis of such trials, as well as suggesting the importance of targeting insight in treatment to increase likelihood of adherence to treatment. There also appear to be small but significant differences in insight based on age and diagnosis within the schizophrenia spectrum.

Longitudinal changes of insight in first episode psychosis and its relation to clinical symptoms, treatment adherence and global functioning: one-year follow-up from the Eiffel study

OBJECTIVES

The Eiffel study is a longitudinal, naturalistic study of patients with first episode psychosis (FEP) designed to evaluate the predictive value of defective insight on treatment adherence and global functioning.

METHODS

Five hundred seventy-seven patients with FEP were assessed at baseline and at a 1-year follow-up. They were compared in terms of sociodemographic factors, psychopathology, insight, treatment adherence and functional outcome. Longitudinal functionality was prospectively assessed with the clinical global impression (CGI) and global assessment of functioning (GAF) rating scales.

RESULTS

At baseline, up to 50% of our sample presented with a lack of insight. Most clinical symptoms, including insight, improved over the follow-up period. Insight, education and social withdrawal significantly predicted CGI and GAF at follow-up. Insight and level of education were predictive of treatment adherence.

CONCLUSIONS

Insight significantly predicted the general clinical course, treatment adherence and functional outcome in our FEP sample after 1 year. Only education additionally accounted for the longitudinal course. Since our results suggest that better insight improves treatment adherence and consequently clinical course and functional outcome, insight could be a specific target of treatment in early intervention programs.

Manic and depressive symptoms and insight in first episode psychosis

Insight impairment is common early in the course of psychosis. Most studies have focused on the relationship between insight and depression, although manic symptoms are also frequent in psychoses. The main aim of this study was to examine the relationship between insight dimensions and manic and depressive symptoms in first-episode psychosis. A group of inpatients in their first psychotic episodes (n=124) were evaluated using the Scale to Assess Unawareness of Mental Disorder, Young Mania Rating Scale and Hamilton Depression Rating Scale. To study the effect of clinical, manic and depressive symptoms on insight, awareness of mental disorder, awareness of the achieved effects of medication, and awareness of the social consequences of having a mental disorder were modelled using ordinal logistic regression techniques. Results showed that greater awareness of mental disorder was significantly related to higher age at first episode together with higher scores for negative and depressive symptoms. The opposite was found to be true in presentations with a higher severity of disease and manic symptoms. The model fitting unawareness of the achieved effects of medication identified the same significant variables, except in the case of negative symptoms. Finally, the model assessing the social consequences of having a mental disorder showed unawareness to be greater when manic symptoms and disease severity were high.

[French adaptation and validation of the scale to assess unawareness of mental disorder]

OBJECTIVES

To validate the French version of the Scale to Assess Unawareness of Mental Disorder (SUMD) in patients with schizophrenia.

METHOD

One hundred patients with schizophrenic disorders were included. Our statistical analyses evaluated interrater reliability, theoretical validity, and convergent or divergent validity. Finally, an exploratory factor analysis was conducted.

RESULTS

The results revealed good psychometric properties for the French version of the SUMD. Both interrater reliability (ICC ranged from 0.68 to 1.00) and internal consistency (Cronbach 0.70) were satisfactory. Criterion validity was confirmed by high correlation values between SUMD scores and scores on the Positive and Negative Syndrome Scale G12 item evaluating insight. Moreover, as hypothesized, there were few associations between SUMD scores and clinical variables. Finally, Principal Component Analyses confirmed the hypothesis of 2 distinct insight dimensions (consciousness and attribution) for both present and past aspects.

CONCLUSIONS

This French version of the SUMD is a reliable and valid measure of insight in schizophrenia. The clinical relevance of its measure and the development of psychosocial interventions to improve insight into illness in patients with schizophrenia are discussed.

A comparison of insight into clinical symptoms versus insight into neuro-cognitive symptoms in schizophrenia

BACKGROUND

Schizophrenia is associated with neuropsychological deficits that have been linked to poor functional outcome. To address this problem, pharmacologic and behavioral treatments are being developed for cognitive impairments, but they will not be well utilized if people with schizophrenia do not perceive a need for treatment.

AIMS

This study compared whether people with schizophrenia have a similar degree of insight into neuro-cognitive symptoms as clinical symptoms, and whether neuro-cognitive and clinical symptoms are similarly related to degree of insight into these two aspects of the illness.

METHOD

Seventy-one patients with schizophrenia were administered measures of clinical and neuro-cognitive status as well as clinician rated measures of insight into clinical and neuro-cognitive symptoms.

RESULTS

Patients had significantly less insight into their neuro-cognitive symptoms than their clinical symptoms. On average, patients had good insight into clinical symptoms and partial insight into neuro-cognitive symptoms. Neuropsychological variables were related to insight into clinical symptoms, but not insight into neuro-cognition. Clinical variables were not significantly related to either type of insight.

CONCLUSIONS

Insight is not a unitary concept and the differences between awareness of neuro-cognition and awareness of clinical symptoms suggest that they have to be addressed separately in treatment. Specific education about cognitive symptoms may be necessary to improve awareness of this aspect of the schizophrenia.

Mental health laws that require dangerousness for involuntary admission may delay the initial treatment of schizophrenia

INTRODUCTION

A long duration of untreated psychosis (DUP) is associated with a worse prognosis, an increased risk of suicide and may be linked to serious violence. Mental health laws that require patients to be dangerous to themselves or to others before they can receive involuntary psychiatric treatment may make it more difficult to treat patients in their first episode of psychosis.

METHODS

The mean and median DUP reported in studies of schizophrenia related psychoses were examined. A comparison was made between the DUP reported from jurisdictions that had an obligatory dangerousness criterion (ODC) and those with other criteria for involuntary treatment.

RESULTS

The average mean DUP in samples from jurisdictions with an ODC was 79.5 weeks, but was only 55.6 weeks in those jurisdictions that did not have an ODC (P < 0.007).

CONCLUSIONS

Mental health laws that require the patient to be assessed as dangerous before they can receive involuntary treatment are associated with significantly longer DUP. As reducing DUP is an intervention that can improve the prognosis of schizophrenia, this finding suggests that mental health laws should be amended to allow treatment on grounds other than dangerousness, at least in the crucial first episode of psychosis.

Insight in first-episode schizophrenia

Objective. To compare insight impairment, including its temporal changes, between remitters and nonremitters in patients with first-episode schizophrenia. Method. Males, consecutively hospitalized with diagnosed first-episode schizophrenia (according to ICD 10), who provided written informed consent, and were reassessed at the 1-year follow-up were included. The psychopathology was evaluated using the Positive and Negative Syndrome Scale (PANSS) prior to acute treatment - on admission; at the end of the acute treatment - at discharge; at the 1-year follow-up. Insight was measured using item G12 from the PANSS. Results. Ninety-three patients (mean age 23 years, mean duration of illness 0.77 years) were reassessed after 1 year. A total of 73/93 patients (78%) fulfilled the criteria for remission. When compared, remitters and nonremitters showed no significant difference in impaired judgement and insight on admission. The mean value of this item was significantly lower at discharge even in nonremitters; however, a significantly higher value was found after 1 year in nonremitters. In remitters the impaired insight decreased significantly at discharge and there was a significant additional decrease after 1 year. In nonremitters there was a significant decrease at discharge; however, a significant increase was observed after 1 year. In the 73 remitters the rate of insight impairment was 79.4% on admission, 46.6% at discharge and 10.9% after 1 year; the same values were 90, 20 and 70% in the 20 nonremitters. In both remitters and nonremitters the lack of judgement and insight was the first or second most frequently observed item at all three time points. The impaired insight on admission was strongly associated with the overall symptomatology, including positive, negative and general psychopathology on admission in both remitters and nonremitters. Only in remitters was the impaired insight at discharge associated with symptoms at discharge, on admission and also after 1 year. The impaired insight at the 1-year follow-up was associated with some symptoms after 1 year in both remitters and nonremitters. Conclusion. Insight may be state dependent, especially in patients with a good outcome. Attitudes towards treatment and insight into the illness may vary during the course of the illness. However, more longitudinal prospective studies are needed to verify such state-related change, and the factors that may underlie the acquisition of insight.

Predicting domain-specific insight of schizophrenia patients from symptomatology, multiple neurocognitive functions, and personality related traits

This study examines the contribution of various neurocognitive functions, clinical characteristics, and personality traits to the prediction of three insight dimensions. Clinically stable schizophrenia patients (n=107) residing in the community were evaluated using the Positive and Negative Syndrome Scale, the Scale for the Assessment of Unawareness of Mental Disorder, and a comprehensive battery of instruments to measure personality related variables and neurocognitive functioning. Step-wise multivariate regression analysis indicates significant association of variability in insight dimensions with neurocognitive functioning (20-41%), personality related traits (8-18% temperament factors, 4-7% self-constructs, 10-14% coping styles), severity of symptoms (about 7%), illness duration (6%), and education (about 5%). Poor insight was attributed to impairment in visual and movement skills, sustained attention, executive functions, intensity of autistic preoccupations and positive symptoms, as well as increased novelty seeking behavior, task and emotion oriented coping styles, better self-esteem, self-efficacy, and higher education. Better awareness was related to better performance of neurocognitive tasks, reward dependence behavior, avoidant coping style, and longer illness duration. Aside from common indicators for the various insight dimensions, we defined specific indicators for each insight dimension. Thus, insight dimensions in schizophrenia patients residing in the community were attributed to neurocognitive and personality related factors rather than to psychopathological symptoms. The findings enable better understanding of the multifactorial nature of insight and highlight targets for more effective intervention and rehabilitation.

The association of insight with psychotic symptoms, depression, and cognition in early psychosis: a 3-year follow-up

Recent research has begun to examine the level of insight following a first episode of psychosis since this may have implications for outcome. Insight was investigated in 278 individuals consecutively admitted to a comprehensive early psychosis treatment program. Insight, symptoms and cognition were assessed on admission and after one, two and three years. Sixty percent had good insight at baseline and this improved significantly to 80% at one year. Insight remained good at years 2 and 3 with 78.6% and 82.8%, respectively, having good insight. A comparison of those with good to those with poor insight revealed that at each assessment point those with poor insight had significantly higher ratings on positive, negative and general psychopathology symptoms (all at p<0.001). Additionally those with good insight had significantly higher levels of depression at baseline (p=0.001). With respect to cognition when using a composite cognitive factor there was a significant advantage for the good insight group at one year (p=0.01). Overall results show that a significant proportion of individuals have good insight following a first episode of psychosis. For this group depression may be a significant concern at least upon initial presentation. Those with poor insight have increased symptoms throughout the first three years and possibly poorer cognitive functioning.

Relationship between insight, cognitive function, social function and symptomatology in schizophrenia: the West London first episode study

OBJECTIVE

To examine the nature and clinical correlates of insight in first-episode schizophrenia, and how these differ from findings in established schizophrenia.

METHOD

Insight (and insight dimensions), clinical symptoms, neurocognitive function and social function were assessed in 94 patients with first-episode schizophrenia or schizophreniform disorder according to DSM-IV criteria.

RESULTS

Greater global insight was associated with more severe depression. Poor overall insight was associated significantly with more severe negative and disorganisation symptoms as well as poor working memory, and at a trend level with lower current IQ. Patients with poor insight perceived themselves to have a better level of independent performance at daily living activities.

CONCLUSION

In first-episode psychosis, the clinical correlates of poor insight are similar to those reported for established schizophrenia. Those patients with greater insight may be at risk of depression. The complex relationships between insight, positive and negative symptoms, neurocognitive dysfunction and social function may reflect the multidimensional nature of insight.

Insight, symptoms and executive functions in schizophrenia

INTRODUCTION

We investigated the relationship of insight with executive functions and symptoms in a group of stabilised inpatients with schizophrenia.

METHODS

Executive functions using an extensive battery constituted of several tests as well as psychopathology were assessed in 38 inpatients with a DSM-IV diagnosis of schizophrenia. Insight was assessed with the Scale to assess Unawareness of Mental Disorder (SUMD).

RESULTS

A principal component analysis of the insight dimensions revealed a three-factor model which accounted for 98% of the variance. Of particular interest is the finding that a composite factor that accounted for 74% of the variance covered insight dimensions that represent a higher degree of insight (awareness of mental disorder, its social consequences, and attribution of symptoms). Only an association between letter fluency and this composite factor was found, which was weakly mediated by depressive symptoms. A stepwise multiple regression analysis revealed a relationship between antipsychotic dose and awareness of medication effect. No association of illness duration and insight was found.

CONCLUSIONS

The findings of partial association between dimensions of insight and measures of executive function supports the growing evidence that insight is a multidimensional phenomenon. Accordingly, they emphasise that in the framework of therapeutic interventions, enhancement of higher levels of insight needs to take into account that patients suffering from schizophrenia have differential impairment in insight dimensions.

Persistent Paranoid Delusions Following the September 11 Terrorist Attacks in a Man with No Pre-existing Mental Illness

The effects of modern day terrorism on mental health are not well understood. Described here is a 51-year-old male with no pre-existing mental illness who developed paranoid delusions related to the September 11, 2001, terrorist attacks shortly after they occurred. After about two years of treatment with quetiapine the patient was no longer delusional about terrorism but experienced extensive paranoid delusions about commonly encountered persons, requiring treatment which continues to the current time. Clinicians should be aware of the possible impact of terrorist activities on the mental health of vulnerable individuals.

Clinical and Social Correlates of Duration of Untreated Psychosis in First-episode Psychosis Patients

Introduction: This study aims to examine the socio-demographic and clinical correlates of the duration of untreated psychosis (DUP) in first-episode psychosis patients in an Asian country. Materials and Methods: Three hundred thirty-four patients from the Early Psychosis Intervention Programme (EPIP) of Singapore were recruited for the study. Socio-demographic data were collected and patients were diagnosed using SCID I (Structural Clinical Interview for DSM-IV Axis I Disorders). Other assessment scales were used to assess the level of psychopathology, overall functioning and the awareness of mental illness. Results: Mean (SD) DUP was 16.3 (31.5) months. Patients who were single, unemployed, or brought by the police had a significantly longer DUP. Patients with a diagnosis of schizophrenia had a longer DUP as compared to patients with other forms of psychosis. The better functioning patients as indicated by a higher Global Assessment of Functioning score and those who were more insightful had a shorter DUP. Conclusions: This study suggests that certain socio-demographic features and clinical diagnosis may determine DUP. Key words: Psychotic disorder, Schizophrenia

Insight in schizophrenia: a review

The issue of insight in schizophrenia must be assumed to be one of the most important aspects of the clinical examination. Comprehensive studies have shown that between 50% and 80% of all patients suffering from schizophrenia do not believe that they have a disorder. In recent years, poor insight in schizophrenia has been the subject of increasing interest, as manifested in a number of studies discussed in the present review. Some of these studies focus on insight correlated to various parameters such as psychopathology, neuropsychology, clinical relevance and compliance. Other studies refer to more theoretical implications, among these the issue of defining the concept of insight: whether insight can be seen as a "primary" phenomenon in schizophrenia, and whether insight may be graduated, dimensioned or increased. Several authors have developed rating scales in an attempt to obtain a measure for the degree or dimension of insight. Here, the range of parameters employed gives an excellent impression of the complexity of the concept of insight. In the concluding discussion, a phenomenological aspect is brought in, in an attempt to place the concept of insight in relation to disturbances of the self in schizophrenia and to primary symptoms in schizophrenia, amongst these autism.

The treatment of schizophrenia: from premorbid manifestations to the first episode of psychosis

To achieve the best therapeutic results in schizophrenia--like most other disorders--primary prevention is preferable to early and prompt treatment, which, in turn, is preferable to treatment of chronically established illness. Unfortunately, there currently exist no accurate markers that can provide information regarding the future course of illness and guide treatment in asymptomatic or mildly symptomatic individuals. Therefore, most treatment efforts are currently focused on patients who have already experienced their first psychotic episode. This paper reviews the efforts to identify accurate markers heralding psychotic illness, as well as treatment considerations in the early phase of the disease.

Agreement between self-rated and clinically assessed symptoms in subjects with psychosis

The aim of this study was to explore the capacity of acutely ill patients with psychosis (N = 40) to self-report their symptoms by comparing self-assessment and objective measures. Positive, negative, and depressive symptoms were rated using the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Calgary Depression Scale. Insight level was measured using the Scale to Assess Unawareness of Mental Disorder. Patients were asked to self-report positive, negative, and depressive symptoms using the Community Assessment of Psychic Experience. Patients presenting with acute psychotic disorders are able to assess fairly their positive, negative, and depressive symptoms. Significant associations were found between self-reported and objective measures of positive, negative, and depressive symptoms independently of insight level. Individual positive and negative symptoms were correctly self-assessed, except for persecutory delusion and alogia, respectively. These results suggest that self-report questionnaires can be used in educational programs to favor the patient's therapeutic adherence.

Insight in early psychosis: a 1-year follow-up

Insight was investigated in 180 individuals consecutively admitted to a comprehensive early psychosis treatment program. Insight was assessed on admission and after 3, 6 and 12 months. Insight improved significantly over 12 months, and was negatively correlated with both positive and negative symptoms, and positively correlated with depressive symptoms at admission. There were no associations with cognition.

Pharmacological Management of First-Episode Schizophrenia and Related Nonaffective Psychoses

Schizophrenia is a severe mental illness characterised by abnormalities of thought and perception that affects 1-2% of the population. Patients who experience a first episode of schizophrenia should be treated early and optimally with antipsychotic agents to lessen the morbidity of the initial episode and possibly improve the course of the illness. Positive psychotic symptoms remit in the majority of patients who are treated with adequate trials of antipsychotic medications, but most relapse within 1 year. Non-adherence is strongly related to the likelihood of recurrence of symptoms. Innovative programmes that integrate early intervention, psychosocial treatments and atypical antipsychotic pharmacotherapy show promise in improving outcomes. The available research supports the use of antipsychotic medications early in the first-episode of schizophrenia and for at least 1 year after remission of positive symptoms. Antidepressants, benzodiazepines and mood stabilisers have roles in the acute and maintenance phases of treatment for some patients. Atypical antipsychotics represent a great advance in the treatment of first-episode schizophrenia with strong evidence for greater tolerability with equal or better therapeutic efficacy. Future research will further define their roles in treatment and hopefully identify targets for prevention of first-episode schizophrenia.
