Abstract
BACKGROUND AND HYPOTHESIS Impaired insight into one's illness is common in first episode psychosis (FEP), is associated with worse symptoms and functioning, and predicts a worse course of illness. Despite its importance, little research has examined the effects of early intervention services (EIS) on insight. DESIGNS This paper evaluated the impact of EIS (NAVIGATE) on insight compared to usual community care (CC) in a large cluster randomized controlled trial. Assessments were conducted at baseline and every 6 months for 2 years. RESULTS A multilevel regression model including all time points showed a significant time by treatment group interaction (P < .001), reflecting greater improvement in insight for NAVIGATE than CC participants. Impaired insight was related to less severe depression but worse other symptoms and functioning at baseline for the total sample. At 6 months, the same pattern was found within each group except insight was no longer associated with depression among NAVIGATE participants. Impaired insight was more strongly associated with worse interpersonal relationships at 6 months in NAVIGATE than in CC, and changes in insight from baseline to 6 months were more strongly correlated with changes in relationships in NAVIGATE than CC. CONCLUSIONS The NAVIGATE program improved insight significantly more than CC. Although greater awareness of illness has frequently been found to be associated with higher depression in schizophrenia, these findings suggest EIS programs can improve insight without worsening depression in FEP. The increased association between insight and social relationships in NAVIGATE suggests these 2 outcomes may synergistically interact to improve each other in treatment.

Abstract
PURPOSE OF REVIEW The aim of this review was to summarize the recent literature on the clinical symptoms, functioning, outcomes and treatments for older adults with chronic schizophrenia. RECENT FINDINGS The number and proportion of older adults with schizophrenia is rapidly increasing. Schizophrenia is a heterogeneous disorder and older adults with schizophrenia display significant variability in symptom severity, quality of life and overall outcomes. Many achieve stable disease remission, some display persistent nonremission and others experience fluctuating symptoms. Depression is commonly reported, and although rates of suicide are higher when compared with age-matched peers, the excess mortality seen in this population is mainly attributed to natural causes of death. Cognitive decline and reduced illness awareness have important implications for functional status and quality of life. Antipsychotics remain essential in the treatment regimen, although elderly patients with chronic disease may be good candidates for gradual dose reduction. Interdisciplinary treatment approaches as well as nonpharmacologic psychosocial interventions play a critical adjunctive role in the treatment of older adults with schizophrenia. SUMMARY Research focusing on schizophrenia in late life is sparse. Too often, older patients are eliminated from research studies or averaged in with all age groups. Thus, there continues to be gaps in our understanding of modifiable predictors of remission and recovery, and the most efficacious and safest treatment approaches for this age group.

Abstract
Poor insight exists in all phases of schizophrenia and is associated with poor clinical prognosis and adverse psychosocial functioning. This is a meta-analysis examining the prevalence of poor insight and its correlates in Chinese patients with schizophrenia. Both major international (PubMed, EMBASE, PsycINFO, and Web of Science) and Chinese (WANFANG and CNKI) databases were systematically searched. The pooled prevalence of poor insight was calculated using the random-effects model. A total of 19 studies with 3112 schizophrenia patients were included. The prevalence of poor insight was 43.4% (95%CI: 36.0%-51.2%). Subgroup and meta-regression analyses revealed that the higher prevalence of poor insight was significantly associated with single-site design, smaller sample size, inpatient status, acute illness phase, higher male proportion, younger age, shorter duration of illness, lower study quality, and earlier publication year. Poor insight is common in Chinese schizophrenia patients. Considering the negative outcomes of poor insight, regular screening and effective psychosocial interventions should be delivered for this vulnerable population.

Exploring the relationship of insight with psychopathology and gender in individuals with schizophrenia spectrum disorders with structural equation modelling. Arch Womens Ment Health 2020; 23:643-655.

Abstract
To model the influence of psychopathology on insight deficits in schizophrenia spectrum patients with a gender-stratified analysis. Five hundred sixteen patients (65.1% men) with schizophrenia spectrum disorders were evaluated in four centres of the metropolitan area of Barcelona (Catalonia). Psychopathological assessment was performed using different PANSS factors. Insight and its three main dimensions were assessed by means of the Scale of Unawareness of Mental Disorder: awareness of the disease (SUMD-1), of the effect of medication (SUMD-2) and of the social consequences of the disease (SUMD-3). Structural equation models (SEMs) were used to fix the model in the total sample and by gender. Additional analyses included age, duration of illness (DOI) and education status (ES). There were no significant differences between men and women in the three main dimensions of insight. The SEMs in the total sample showed a modest fitting capacity. Fitting improved after a gender-stratified analysis (particularly in women). In men, positive and excited symptoms were associated with poorer insight in all SUMD dimensions, whereas depressive symptoms were associated with better insight. ES in men was also associated with better SUMD-2 or SUMD-3. In contrast, in women, symptoms did not have a negative effect on SUMD-1 or SUMD-2. However, positive symptoms were associated with a poorer SUMD-3, whereas depressive symptoms were associated with better SUMD-3. Moreover, education level was also associated with a better SUMD-3. A gender approach improved the comprehension of the model, supporting the relevance of gender analysis in the study of insight.

Abstract
De-institutionalization of mental health patients has evolved, over nearly 3 generations now, to a status quo of mental health patients experiencing myriad contacts with first-responders, primarily police, in lieu of care. The current institutions in which these patients rotate through are psychiatric emergency units, emergency rooms, jails, and prisons. Although more police are now specially trained to respond to calls that involve mental health patients, the criminalization of persons with mental illness has been steadily increasing over the past several decades. There have also been deaths. The Crisis Intervention Team (CIT) model fosters mental health acumen among first responders, and facilitates collaboration among first responders, mental health professionals, and mental health patients and their families. Here, we review some modern, large city configurations of CIT, the co-responder model, the mitigating effects of critically situated community-based programs, as well as barriers to the success of joint efforts to better address this pressing problem.

Abstract
Lack of insight, i.e., unawareness of one's mental illness, is frequently encountered in psychiatric conditions. Insight is the capacity to recognize (psychical insight) and accept one's mental illness (emotional insight). Insight growth necessitates developing an objective perspective on one's subjective pathological experiences. Therefore, insight has been posited to require undamaged self-reflexion and cognitive perspective-taking capacities. These enable patients to look objectively at themselves from the imagined perspective of someone else. Preserved theory-of-mind performances have been reported to positively impact insight in psychosis. However, some patients with schizophrenia or obsessive-compulsive disorders, although recognizing their mental disease, are still not convinced of this and do not accept it. Hence, perspective-taking explains psychical insight (recognition) but not emotional insight (acceptance). Here, we propose a new conceptual model. We hypothesize that insight growth relies upon the association of intact self-reflexion and empathic capacities. Empathy (feeling into someone else) integrates heterocentered visuo-spatial perspective (feeling into), embodiment, affective (feeling into) and cognitive processes, leading to internally experience the other's thought. We posit that this subjective experience enables to better understand the other's thought about oneself and to affectively adhere to this. We propose that the process of objectification, resulting from empathic heterocentered, embodiment, and cognitive processes, generates an objective viewpoint on oneself. It enables to recognize one's mental illness and positively impacts psychical insight. The process of subjectification, resulting from empathic affective processes, enables to accept one's illness and positively impacts emotional insight. That is, affectively experiencing the thought of another person about oneself reinforces the adhesion of the emotional system to the objective recognition of the disease. Applying our model to different psychiatric disorders, we predict that the negative effect of impaired self-reflexion and empathic capacities on insight is a transnosographic state and that endophenotypical differences modulate this common state, determining a psychiatric disease as specific.

Abstract
BACKGROUND While insight in schizophrenia improves with treatment, significant impairments often persist. The degree of persistence is not well characterised. AIMS We assessed patient and clinician-rated changes in insight in acutely ill, minimally treated first-episode schizophrenia spectrum disorder patients over 24 months of standardised treatment with a depot antipsychotic. METHOD This single arm open label longitudinal cohort study included 105 participants with first-episode schizophrenia, schizophreniform or schizoaffective disorder. Insight was assessed at months 0, 6, 12 and 24 using the patient-rated Birchwood Insight Scale (BIS) and clinician-rated global insight item of the Positive and Negative Syndrome Scale (PANSS). Changes in insight over time were assessed using linear mixed-effect models for continuous repeated measures. Relationships between insight and psychopathology, functionality, cognition and quality of life were assessed with regression models. RESULTS There was significant improvement over time for the PANSS insight item (p < 0.0001). However, the only significant improvement for the BIS was with the Need for Treatment subscale (p = 0.01). There were no significant improvements noted for the Symptom Attribution (p = 0.7) and Illness Awareness (p = 0.2) subscales, as well as the BIS Total score (p = 0.6). Apart from depressive symptoms at baseline, there were no significant predictors of patient-rated insight. CONCLUSIONS Clinicians should note that, even when treatment is assured and response is favourable, fundamental impairments in patient-rated insight persist.

Abstract
The aim of this study is to investigate the validity of the Norwegian version of the Insight Scale (IS) in large and representative samples of patients with schizophrenia spectrum disorders, bipolar I disorder and bipolar II disorder. A total of 997 participants were included (schizophrenia spectrum disorders: 557; bipolar I disorder: 282; bipolar II disorder: 138). Confirmatory factor analysis was conducted to investigate the construct validity and bivariate correlational analysis was applied to investigate convergent validity. Confirmatory factor analyses indicated a reasonable model fit to the original three-factor subscale structure of the IS in all three diagnostic groups. The IS total score and its subscales correlated significantly with both the insight items in the Young Mania Rating Scale and the Positive and Negative Syndrome Scale in both schizophrenia spectrum disorders and bipolar I disorder. In the bipolar II disorder group, however, the IS subscales correlated poorly with both the observer-rated measures. Our study supports the construct validity of the IS in both schizophrenia spectrum disorder- and bipolar disorder populations. The study also demonstrates that patients' self-reports of insight correspond to observer-based single item ratings of insight in bipolar I disorder and schizophrenia spectrum disorders.

Abstract
Lack of insight is a neurocognitive problem commonly encountered in patients with psychotic disorders that negatively affects treatment compliance and prognosis. Measurement of insight is based on self-report scales, which are limited due to subjectivity. This study aimed to determine the correlation between resting state beta and gamma power in 23 patients with schizophrenia and insight. It was observed that as beta and gamma power measured via qualitative electroencephalography (qEEG) increased the level of insight decreased. Negative correlation was found in F3, C3, Cz for gamma activity and in F3 and C3 for beta activity. This finding indicates that resting state qEEG could be used to evaluate the level of insight in patients with schizophrenia.

Abstract
OBJECTIVE The purpose of this study was to determine if schizoaffective disorder in older adults is differentiated from schizophrenia and bipolar disorder with respect to community functioning, cognitive functioning, psychiatric symptoms, and service use. DESIGN Secondary analysis of baseline data collected from the Helping Older People Experience Success psychosocial skills training and health management study. SETTING Three community mental health centers in New Hampshire and Massachusetts. PARTICIPANTS Adults over the age of 50 (N = 139, mean age: 59.7 years, SD: 7.4 years) with persistent functional impairment and a diagnosis of schizoaffective disorder (N = 52), schizophrenia (N = 51), or bipolar disorder (N = 36). MEASUREMENTS Health status (36-Item Short Form Health Survey [SF-36]), performance-based community living skills (UCSD Performance-Based Skills Assessment), neuropsychological functioning (Delis-Kaplan Executive Functioning subtests), psychiatric symptoms (Brief Psychiatric Rating Scale, Center for Epidemiologic Studies Depression Scale, Scale for the Assessment of Negative Symptoms), medical severity (Charlson comorbidity index), and acute service use. RESULTS Older adults with schizoaffective disorder had depressive symptoms of similar severity to bipolar disorder, and thought disorder symptoms of similar severity to schizophrenia. Schizoaffective disorder compared with schizophrenia was associated with better community functioning, but poorer subjective physical and mental health functioning as measured by the SF-36. Older adults with schizoaffective disorder had greater acute hospitalization compared with adults with schizophrenia, though their use of acute care services was comparable to individuals with bipolar disorder. CONCLUSIONS Findings from this study suggest that schizoaffective disorder in older adults occupies a distinct profile from either schizophrenia or bipolar disorder with respect to community functional status, symptom profile, and acute services utilization.

Self versus informant reports on the specific levels of functioning scale: Relationships to depression and cognition in schizophrenia and schizoaffective disorder.

Abstract
The goal of the current study was to examine the relationships between insight and both cognitive function and depression in schizophrenia and schizoaffective disorder, and to determine if there were similar relationships across diagnostic categories. We examined discrepancies between self and informant reports of function on the Specific levels of function scale as a metric of insight for interpersonal, social acceptance, work and activities. We examined two samples of individuals with schizophrenia and/or schizoaffective disorder (Ns of 188 and 67 respectively). In Sample 1, cognition was measured using the Dot Probe Expectancy Task. In Sample 2, cognition was measured by averaging several subtests from the MATRICS consensus cognitive battery, as well as additional measures of working memory. In both samples, depression was measured using the Brief Psychiatric Rating Scale. In both samples, we found significant relationships between worse cognition and overestimations of work function, as well as between higher depression levels and underestimation of interpersonal function. These relationships were specific to interpersonal and work function, with significantly stronger correlations with interpersonal and work function compared to the other areas of function. Similar results were found across diagnostic categories. These results have important implications for treatment planning, as they suggest the need to take into account depression and cognitive function when evaluating the patient's self-report of function, and highlight the utility of informant reports in evaluating function and treatment planning. Further, they add to the literature on the similarity across schizophrenia and schizoaffective disorder in a variety of pathological mechanisms.

Abstract
Implementing the most suitable treatment strategies and making appropriate clinical decisions about individuals with a first episode of psychosis (FEP) is a complex and crucial task, with relevant impact in illness outcome. Treatment approaches in the early stages should go beyond choosing the right antipsychotic drug and should also address tractable factors influencing the risk of relapse. Effectiveness and likely metabolic and endocrine disturbances differ among second-generation antipsychotics (SGAs) and should guide the choice of the first-line treatment. Clinicians should be aware of the high risk of cardiovascular morbidity and mortality in schizophrenia patients, and therefore monitoring weight and metabolic changes across time is mandatory. Behavioral and counseling interventions might be partly effective in reducing weight gain and metabolic disturbances. Ziprasidone and aripiprazole have been described to be least commonly associated with weight gain or metabolic changes. In addition, some of the SGAs (risperidone, amisulpride, and paliperidone) have been associated with a significant increase of plasma prolactin levels. Overall, in cases of FEP, there should be a clear recommendation of using lower doses of the antipsychotic medication. If no or minimal clinical improvement is found after 2 weeks of treatment, such patients may benefit from a change or augmentation of treatment. Clinicians should provide accurate information to patients and relatives about the high risk of relapse if antipsychotics are discontinued, even if patients have been symptom free and functionally recovered on antipsychotic treatment for a lengthy period of time.

This study aimed to evaluate gender differences in the deficit of insight in psychosis and determine influences of clinical, functional, and sociodemographic variables. A multicenter sample of 401 adult patients with schizophrenia and other psychotic disorders who agreed to participate was evaluated in four centers of the metropolitan area of Barcelona (Catalonia). Psychopathological assessment was performed using the Positive and Negative Syndrome Scale Lindenmayers' Factors. Insight and its dimensions were assessed by means of the Scale of Unawareness of Mental Disorder. Significant differences were apparent neither between men and women in the three dimensions of insight, nor in the total awareness, nor in the total attribution subscales. However, statistically significant differences were found in awareness and attribution of particular symptoms. Women showed a worse awareness of thought disorder and alogia and a higher misattribution of apathy. Higher cognitive and positive symptoms, early stage of the illness, and having been married explained deficits of insight dimensions in women. In men, other variables such as lower functioning, higher age, other psychosis diagnosis, and, to a lower extent, higher scores in cognitive, positive, and excitative symptoms, explained deficits of insight dimensions. These data could help to design gender-specific preventive and therapeutic strategies.

Abstract
BACKGROUND Risperidone is the first new generation antipsychotic drug made available in a long-acting injection formulation. OBJECTIVES To examine the effects of depot risperidone for treatment of schizophrenia or related psychoses in comparison with placebo, no treatment or other antipsychotic medication.To critically appraise and summarise current evidence on the resource use, cost and cost-effectiveness of risperidone (depot) for schizophrenia. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Register (December 2002, 2012, and October 28, 2015). We also checked the references of all included studies, and contacted industry and authors of included studies. SELECTION CRITERIA Randomised clinical trials comparing depot risperidone with other treatments for people with schizophrenia and/or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed trial quality and extracted data. For dichotomous data, we calculated the risk ratio (RR), with 95% confidence interval (CI). For continuous data, we calculated mean differences (MD). We assessed risk of bias for included studies and created 'Summary of findings' tables using GRADE. MAIN RESULTS Twelve studies, with a total of 5723 participants were randomised to the following comparison treatments: Risperidone depot versus placebo Outcomes of relapse and improvement in mental state were neither measured or reported. In terms of other primary outcomes, more people receiving placebo left the study early by 12 weeks (1 RCT, n=400, RR 0.74 95% CI 0.63 to 0.88, very low quality evidence), experienced severe adverse events in short term (1 RCT, n=400, RR 0.59 95% CI 0.38 to 0.93, very low quality evidence). There was however, no difference in levels of weight gain between groups (1 RCT, n=400, RR 2.11 95% CI 0.48 to 9.18, very low quality evidence). Risperidone depot versus general oral antipsychotics The outcome of improvement in mental state was not presented due to high levels of attrition, nor were levels of severe adverse events explicitly reported. Most primary outcomes of interest showed no difference between treatment groups. However, more people receiving depot risperidone experienced nervous system disorders (long-term:1 RCT, n=369, RR 1.34 95% CI 1.13 to 1.58, very-low quality evidence). Risperidone depot versus oral risperidoneData for relapse and severe adverse events were not reported. All outcomes of interest were rated as moderate quality evidence. Main results showed no differences between treatment groups with equivocal data for change in mental state, numbers leaving the study early, any extrapyramidal symptoms, weight increase and prolactin-related adverse events. Risperidone depot versus oral quetiapine Relapse rates and improvement in mental state were not reported. Fewer people receiving risperidone depot left the study early (long-term: 1 RCT, n=666, RR 0.84 95% CI 0.74 to 0.95, moderate quality evidence). Experience of serious adverse events was similar between groups (low quality evidence), but more people receiving depot risperidone experienced EPS (1 RCT, n=666, RR 1.83 95% CI 1.07 to 3.15, low quality evidence), had greater weight gain (1 RCT, n=666, RR 1.25 95% CI 0.25 to 2.25, low quality evidence) and more prolactin-related adverse events (1 RCT, n=666, RR 3.07 95% CI 1.13 to 8.36, very low quality evidence). Risperidone depot versus oral aripiprazoleRelapse rates, mental state using PANSS, leaving the study early, serious adverse events and weight increase were similar between groups. However more people receiving depot risperidone experienced prolactin-related adverse events compared to those receiving oral aripiprazole (2 RCTs, n=729, RR 9.91 95% CI 2.78 to 35.29, very low quality of evidence). Risperidone depot versus oral olanzapineRelapse rates were not reported in any of the included studies for this comparison. Improvement in mental state using PANSS and instances of severe adverse events were similar between groups. More people receiving depot risperidone left the study early than those receiving oral olanzapine (1 RCT, n=618, RR 1.32 95% CI 1.10 to 1.58, low quality evidence) with those receiving risperidone depot also experiencing more extrapyramidal symptoms (1 RCT, n=547, RR 1.67 95% CI 1.19 to 2.36, low quality evidence). However, more people receiving oral olanzapine experienced weight increase (1 RCT, n=547, RR 0.56 95% CI 0.42 to 0.75, low quality evidence). Risperidone depot versus atypical depot antipsychotics (specifically paliperidone palmitate)Relapse rates were not reported and rates of response using PANSS, weight increase, prolactin-related adverse events and glucose-related adverse events were similar between groups. Fewer people left the study early due to lack of efficacy from the risperidone depot group (long term: 1 RCT, n=749, RR 0.60 95% CI 0.45 to 0.81, low quality evidence), but more people receiving depot risperidone required use of EPS-medication (2 RCTs, n=1666, RR 1.46 95% CI 1.18 to 1.8, moderate quality evidence). Risperidone depot versus typical depot antipsychoticsOutcomes of relapse, severe adverse events or movement disorders were not reported. Outcomes relating to improvement in mental state demonstrated no difference between groups (low quality evidence). However, more people receiving depot risperidone compared to other typical depots left the study early (long-term:1 RCT, n=62, RR 3.05 95% CI 1.12 to 8.31, low quality evidence). AUTHORS' CONCLUSIONS Depot risperidone may be more acceptable than placebo injection but it is hard to know if it is any more effective in controlling the symptoms of schizophrenia. The active drug, especially higher doses, may be associated with more movement disorders than placebo. People already stabilised on oral risperidone may continue to maintain benefit if treated with depot risperidone and avoid the need to take tablets, at least in the short term. In people who are happy to take oral medication the depot risperidone is approximately equal to oral risperidone. It is possible that the depot formulation, however, can bring a second-generation antipsychotic to people who do not reliably adhere to treatment. People with schizophrenia who have difficulty adhering to treatment, however, are unlikely to volunteer for a clinical trial. Such people may gain benefit from the depot risperidone with no increased risk of extrapyramidal side effects.

Abstract
OBJECTIVES There are limited studies on the factors that can predict the presence of impaired clinical insight specifically in an Emergency Room (ER) psychiatric patient population. The objective of this study is to examine the factors that can predict the likelihood that a patient presenting to the ER will have impaired clinical insight. METHODS Nineteen independent demographic and clinical factors contained on data assessment tools for 337 patients assessed by the crisis team in the ER over 6 months were compiled and analysed using SPSS Version 20 with univariate analyses and logistic regression. RESULTS Patients who were unemployed or had a history of self-harm or had psychotic symptoms on mental state examination were about two, three and six times, respectively, more likely to have impaired clinical insight compared with those who were employed, had no history of self-harm or had no psychotic symptoms on mental state examination, controlling for other factors in the logistic regression model. CONCLUSION Patients who are unemployed, have a history of self-harm or have psychotic symptoms following as psychiatric assessment in the ER may benefit from an insight-oriented psychotherapy.

Differential effects of antipsychotic drugs on insight in first episode schizophrenia: Data from the European First-Episode Schizophrenia Trial (EUFEST). Eur Neuropsychopharmacol 2015; 25:808-16.

Abstract
Although antipsychotics are widely prescribed, their effect of on improving poor illness insight in schizophrenia has seldom been investigated and therefore remains uncertain. This paper examines the effects of low dose haloperidol, amisulpride, olanzapine, quetiapine, and ziprasidone on insight in first-episode schizophrenia, schizoaffective disorder, or schizophreniform disorder. The effects of five antipsychotic drugs in first episode psychosis on insight were compared in a large scale open randomized controlled trial conducted in 14 European countries: the European First-Episode Schizophrenia Trial (EUFEST). Patients with at least minimal impairments in insight were included in the present study (n=455). Insight was assessed with item G12 of the Positive and Negative Syndrome Scale (PANSS), administered at baseline and at 1, 3, 6, 9, and 12 months after randomization. The use of antipsychotics was associated with clear improvements in insight over and above improvements in other symptoms. This effect was most pronounced in the first three months of treatment, with quetiapine being significantly less effective than other drugs. Effects of spontaneous improvement cannot be ruled out due to the lack of a placebo control group, although such a large spontaneous improvement of insight would seem unlikely.

Abstract
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.

Abstract
Antipsychotics are the mainstay of the long-term treatment of patients with schizophrenia. In this context, the evidence also supports the effectiveness of long-acting injections (LAIs) or depots of antipsychotics regarding their relapse-preventing properties. When a LAI formulation of risperidone was launched as the first second-generation depot, there was a renaissance of interest in these formulations. In the meantime, olanzapine, paliperidone, and aripiprazole have been approved by regulatory authorities as LAIs in various countries. All studies using the new-generation depots have shown a clear advantage over placebo regarding relapse prevention and symptom reduction. Safety profiles of the long-acting compounds are comparable to their oral formulations with the exception of olanzapine pamoate injections, which can sometimes lead to a post-injection delirium. Despite the fact that many treatment guidelines recommend LAI antipsychotics as an important treatment option for the long-term management of schizophrenia, they are still most frequently used in chronically ill patients with considerable compliance problems. It is imperative to overcome this indication bias in order to be able to utilize all available treatment options in the long-term management of schizophrenia. There is little evidence on comparisons between LAIs and their oral mother compounds, and even less concerning effectiveness comparisons between different depots. The purpose of this manuscript is to review the recent clinical evidence on new-generation depot antipsychotics.

Abstract
Insight may vary across psychosis risk syndrome (PRS), first-episode schizophrenia (FES), or multiepisode schizophrenia (MES). We aimed to compare insight domains (awareness, relabeling, and compliance) in PRS, FES, and MES groups and to correlate scores with psychopathological measures. Insight was assessed in 48 (14 PRS, 16 FES, and 18 MES) patients using the Schedule for the Assessment of Insight-Expanded Version. We conducted psychopathological assessment through the Brief Psychiatric Rating Scale (BPRS). In the whole group, the BPRS psychosis factor correlated with all insight domains. In the MES group, the more severe the anxiety/depression, the higher the insight score in the symptom relabeling domain. Insight did not differ significantly between the PRS, FES, and MES groups. Our results suggest that, across different phases of the illness, lack of insight behaves like a trait and is modulated by positive symptom severity. Anxiety and depression may be associated with increased insight in patients with chronic schizophrenia.

Abstract
OBJECTIVE Poor insight, or awareness of illness, has a negative impact on the outcome of the psychosis, and is therefore a logical target for treatment. A meta-analysis of the effect of psychological and pharmacological treatments on insight in psychosis was conducted to give a comprehensive overview of effective interventions. METHODS An inclusive literature search (1975-April 2012) was performed in PubMed, ISI Web of Science, and EMBASE. The search terms used were "Insight", "Awareness", "Treatment", "Psychosis", "Therapy" and "Schizophrenia", no language specified. A cross-reference search of eligible articles was performed to identify studies not found in the computerized search. Effect sizes (Cohen's d) of each study and overall were calculated under a random effects model with 95% confidence intervals. RESULTS Our literature search resulted in approximately 350 abstracts. Nineteen RCTs that examined treatment effects on insight in patients with psychotic disorders were included. Overall, the interventions had a medium effect (d=.34, 95% CI, 0.12-0.57). The effects of CBT, adherence therapy and psycho-education were small to moderate, but not significant, probably due to a lack of power. There were insufficient data to allow a statistical evaluation of the effect of skills training, medication, video-confrontation and comprehensive intervention programs consisting of multiple components. Few adverse effects on mood were documented but this aspect was seldom quantified. CONCLUSION There is a paucity of studies providing data regarding treatment for impaired insight in psychosis. Nevertheless, from the published literature in this meta-analysis, we can confirm that it is a potential therapeutic target and that it is amenable to improvement. Comprehensive intervention programs consisting of multiple components may be particularly promising. Improvements in insight did not seem to be associated with increased depression.

Abstract
BACKGROUND Lack of insight is a core feature of schizophrenia and is associated with structural brain abnormalities. The functional neuroanatomy of insight has only recently been investigated. When people evaluate their personality traits compared to those of another, activation is seen in central midline structures (CMS) of the brain. This study set out to compare cerebral activation in schizophrenia patients versus controls during a self-evaluation task which included positive and negative traits as well as mental and physical illness terms. METHODS Eleven schizophrenia patients and 8 healthy controls, matched for age were studied. Insight was assessed using the Schedule for the Assessment of Insight-expanded version (SAI-E). FMRI data were obtained with a 1.5 Tesla GE system and interactions between participant group, self versus other, significant at the cluster level, were recorded. RESULTS Significant hypoactivation in the medial superior frontal gyrus (dorsomedial prefrontal cortex) was observed in patients vs. controls during self-evaluation of all traits combined. A second cluster of hypoactivation in the posterior cingulate was also detected. When the response to individual traits was explored, underactivation in other frontal regions plus right inferior parietal lobule emerged and this tended to correlate, albeit weakly with lower insight scores. Further, there were areas of hyperactivation relative to controls in anterior cingulate, frontal and parietal regions (especially precuneus) which showed moderate inverse correlations with insight scores. CONCLUSIONS We have demonstrated that the CMS, identified as a key system underpinning self-evaluation, is dysfunctional in patients with schizophrenia, particularly dorso-medial PFC. This may have implications for lack of insight in schizophrenia. Hypofunction within the dorsomedial prefrontal region seems to be particularly important although other posterior and lateral cortical regions play a part and may modulate self-evaluative responses depending on the type of trait under consideration.

Abstract
OBJECTIVE To analyze demographical, clinical, and therapeutic variables that may be associated with pharmacological non-adherence in a sample of schizoaffective patients, bipolar type. METHOD Adherence to treatment and its clinical correlates were assessed at the end of a 10-year follow-up in 76 patients meeting DSM-IV-TR diagnosis of schizoaffective disorder, bipolar type. Adherent and poorly adherent patients were compared regarding clinical and therapeutic variables. RESULTS The rate of poorly adherent patients was 32/76 (41.2%) of the sample. Adherent patients were more likely to have presented an affective episode at illness onset and to have fewer purely - non-affective - psychotic episodes. Demographic or other clinical variables were not found to be associated to treatment adherence. Family history for psychiatric disorders or suicide did not correlate either, and neither did any specific pharmacological agent. CONCLUSION Rates of non-adherence in schizoaffective disorder are high. Adherence seems to be associated to a more affective course of illness (affective first episode and fewer purely psychotic episodes). Patients with more prominent schizophrenia-like characteristics could be at higher risk for poor adherence and need to be closely followed and monitored. Even when properly treated, schizoaffective disorder is a disabling and severe disorder with high risk for recurrences.

Abstract
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.

Abstract
BACKGROUND Adolescence is a key life period for the development of depression. Predicting the development of depression in adolescence through detecting specific early symptoms may aid in the development of timely screening and intervention programmes. METHODS We administered the Short Mood and Feelings Questionnaire (SMFQ) to 5769 American and Australian students aged 10 to 15 years, at two time points, separated by 12 months. We attempted to predict high levels of depression symptoms at 12 months from symptoms at baseline, using statistical approaches based upon the quality, as well as the quantity, of depression symptoms present. These approaches included classification and regression trees (CART) and logistic regression. RESULTS A classification tree employing four SMFQ items, such as feelings of self-hatred and of being unloved, performed almost as well as all 13 SMFQ items at predicting subsequent depression symptomatology. LIMITATIONS Depression was measured using a self-report instrument, rather than a criterion standard diagnostic interview. CONCLUSION Further validation on other populations of adolescents is required: however the results suggest that several symptoms of depression, especially feelings of self-hatred, and being unloved, are associated with increased levels of self-reported depression at 12 months post baseline. Although screening for depression can be problematic, symptoms such as the ones above should be considered for inclusion in screening tests for adolescents.

Abstract
AbstractBackgroundSchizophrenia and bipolar disorder are associated with impairments in insight, leading to a poorer clinical outcome and functioning. Earlier studies comparing the two disorders on the basis of insight included inpatients or patients who were clinically symptomatic. The current study therefore assessed patients in remission of affective symptoms and positive symptoms of schizophrenia.MethodsSchizophrenia and bipolar disorder patients (n = 32, n = 34; respectively) underwent clinical and functional evaluations. Insight was assessed using the Scale to assess Unawareness of Mental Disorder (SUMD) and the Positive and Negative Syndrome Scale (PANSS). Attention was assessed using a continuous performance task (CANTAB's Rapid Visual Information Processing).ResultsSchizophrenia patients displayed poorer insight into having a mental disorder and into the social consequences thereof compared to the bipolar disorder patients. They were also less aware of their anhedonia-asociality. Age, however, was significantly correlated with insight and differences in insight between the patient groups became nonsignificant when age was used as a covariate in the statistical analyses. Age was not a moderating variable of the relationship between diagnosis and insight.ConclusionsSignificant differences in insight held by the two patient groups might be related to age disparities between patient groups. Earlier studies did not adequately address these age differences, their cause and their potential effects on findings. These issues are explored with regard to the findings of the current study, as well as earlier studies, emphasizing the need for further research of the relationship between age and insight.

Abstract
Patients with schizophrenia are often characterized as lacking insight or awareness into their illness and symptoms, yet despite considerable research, we still lack a full understanding of the factors involved in causing poor awareness. Within schizophrenia, there has been shown to be a fractionation across dimensions of awareness into mental illness: of being ill, of symptoms, and of treatment compliance. Recently, attention has turned to evidence of a fractionation between awareness of illness and of cognitive impairments and functioning. The current study investigated the degree of fractionation across a broad range of domains of function in schizophrenia and how each domain may be associated with neuropsychological functioning, clinical, mood, and demographic variables. Thirty-one mostly chronic stable patients with schizophrenia completed a battery of neuropsychological tests and measures of psychopathology, including mood. Cognitive insight and awareness of illness, symptoms, memory, and behavioral functioning were also measured. Insight and awareness were assessed using a combination of semistructured interview, observer-rated, self-rated, and objective measures, and included measures of the discrepancy between carer and self-ratings of impairment. Results revealed that awareness of functioning in each domain was largely independent and that awareness in each domain was predicted by different factors. Insight into symptoms was relatively poor while insight into cognitive deficits was preserved. Relative to neuropsychological variables, cognitive insight, comprising self-certainty and self-reflexivity, was a greater predictor of awareness. In conclusion, awareness is multiply fractionated and multiply determined. Therapeutic interventions could, therefore, produce beneficial changes within specific domains of awareness.
