Autistic Symptoms in Schizophrenia: Impact on Internalized Stigma, Well-Being, Clinical and Functional Characteristics.

Autism Spectrum Disorders (ASD) symptoms and internalized stigma (or self-stigma) can have a negative impact on cognitive and functional outcomes in people living with schizophrenia. Aim of the present study were to assess and compare internalized stigma, subjective well-being and other socio-demographic, clinical and functional characteristics in people diagnosed with schizophrenia with and without prominent autistic features. Ninety-four inpatients were assessed with measures of internalized stigma, subjective well-being, global clinical severity, schizophrenia symptoms severity, real-world functioning, medication side effects and attitude toward prescribed medications. Subjects with high levels of ASD symptoms were identified with the PANSS Autism Severity Score and compared to other participants. Predictors of prominent ASD features were also assessed. Thirteen patients showed prominent ASD symptoms. They were characterized by fewer years of education, worse real-world functioning and greater symptoms severity. No between-group differences were observed regarding subjective well-being and global internalized stigma severity; however, participants in the "autistic schizophrenia" group showed better stigma resistance. A worse clinical condition and fewer years of education emerged as predictors of autistic schizophrenia. Despite showing a more severe clinical presentation of the disorder and worse functional impairment, participants with prominent ASD symptoms do not present worse subjective well-being or more severe internalized stigma; on the contrary, they show better stigma resistance. ASD symptoms could therefore play a protective role in the internalization of stigma.

Internalized stigma among people with schizophrenia: Relationship with socio-demographic, clinical and medication-related features.

BACKGROUND: People with schizophrenia are at high risk of suffering from stigma and internalizing it. Recently, a better understanding of the stigma process has shifted the attention from public stigma to self-stigma, which is deeply debilitating. This study aimed to assess factors associated to self-stigma by evaluating socio-demographic, clinical and treatment-related variables in a group of subjects diagnosed with schizophrenia and to identify predictors of high internalized stigma. METHODS: Ninety-four inpatients accessing rehabilitative centers with a diagnosis of schizophrenia were included in this cross-sectional study. Measures included both patient-rated scales, assessing internalized stigma, attitude toward medications, side effects experience and subjective well-being, and clinician-rated scales, assessing schizophrenia symptoms and global clinical severity and antipsychotic-related side effects. RESULTS: Twenty-one patients (22.3%) showed high internalized stigma while 73 (77.7%) did not. Patients experiencing more medication adverse effects and worse subjective well-being were more likely to suffer from internalized stigma according to a logistic regression analysis. Extrapyramidal, psychic and some autonomic reactions also emerged as individual predictors of self-stigma in a separate regression analysis. CONCLUSIONS: Self-stigma and subjective medication side effects perception represent a relevant issue in patients' life and should be carefully taken into account in clinical practice.

At-risk gambling in patients with severe psychiatric illness and in community subjects matched for age and sex.

In the recent literature the rates of gambling in psychiatric patients have been compared only indirectly with those found in community samples and no study has so far matched a clinical sample with community controls. We selected 875 outpatients attending two community mental health centers and 3.500 community subjects, matched for age and sex. At-risk gambling was defined according to the four categories of the Canadian Problem Gambling Index (CPGI) scores: 0 no-risk, 1-2 low-risk, 3-7 moderate-risk, 8+ high-risk. Data were also collected on substance, alcohol, and tobacco use. Patients were diagnosed with schizophrenia, bipolar disorder, unipolar depression, cluster B personality. At-risk gambling was significantly higher in psychiatric patients compared to community subjects. In the univariate multinomial logistic regression analysis, high-risk gambling was associated with lifetime substance use and being unmarried, moderate-risk with age at onset of alcohol use and lifetime tobacco use, and low-risk with higher education. In the multinomial logistic regression analysis high risk-gambling in psychiatric patients was four times that of community controls, while in substance users high-risk gambling was two times that of non-users. The results suggest that screening for gambling could improve the care of psychiatric patients who suffer from a comorbid behavioral addiction.

Adult ADHD: Prevalence and Clinical Correlates in a Sample of Italian Psychiatric Outpatients.

Objective: ADHD remains a largely underdiagnosed disorder in Europe and especially in Italy. Aims of the present study were to assess the prevalence of ADHD and its clinical and demographic correlates in a large sample of Italian outpatients. Method: 634 outpatients accessing psychiatric services were assessed with the Mini-International Neuropsychiatric Interview (MINI) Plus V. 5.0.0 interview and the Adult ADHD self-report Scale Symptoms Checklist (ASRS)-V 1.1 Short Form. Patients positive to the ASRS-V 1.1 were assessed with the Diagnostic Interview for ADHD in Adults (DIVA) 2.0. Results: Of the total patients' sample, 81 (12.8%) were positive on the ASRS-V 1.1. After performing the DIVA 2.0, 44 patients (6.9%) met the criteria for Adult ADHD. Significant clinical and demographic differences between ADHD positive and negative groups were found. Conclusion: The prevalence and correlates of ADHD comorbidity in our outpatient psychiatric population were comparable to those found in other high-income countries. Considering the prevalence of ADHD and its impact on functioning, implementing specific knowledge on this subject is needed.

Social Cognition in a Research Domain Criteria Perspective: A Bridge Between Schizophrenia and Autism Spectra Disorders.

Schizophrenia and autism spectra disorders are currently conceptualized as distinct clinical categories. However, the relationship between these two nosological entities has been revisited in recent years due to the evidence that they share some important clinical and neurobiological features, putting into question the nature and the extent of their commonalities and differences. In this respect, some core symptoms that are present in both disorders, such as social cognitive deficits, could be a primary target of investigation. This review briefly summarizes the commonalities and overlapping features between schizophrenia and autism spectra disorders in social cognitive functions, considering this construct in a Research Domain Criteria perspective. The clinical manifestation of deficits in social cognition are similar in schizophrenia spectrum disorders and autism spectrum disorders, and brain areas that appear to be altered in relation to these impairments are largely shared; however, the results of various studies suggest that, in some cases, the qualitative nature of these alterations may be different in the two spectra. Moreover, relevant differences could be present at the level of brain networks and connections. More research is required in this field, regarding molecular and genetic aspects of both spectra, to better define the neurobiological mechanisms involved in social cognition deficits, with the objective of developing specific and targeted treatments.

The Long-Term Effectiveness of Psychoeducation for Bipolar Disorders in Mental Health Services. A 4-Year Follow-Up Study.

Aims: The aims of the present study were to assess: the effectiveness of psychoeducation in mental health service (MHSs) in terms of time to first hospitalization during 4-year follow-up; the number and the days of hospitalizations, and the number of people hospitalized at 4-year follow-up; and variables associated with better outcome in BD patients. Methods: This is a controlled study involving an experimental group (N = 57) and a control group (N = 52). The treatment phase consists of 21 weeks, in which all participants received TAU, while the experimental group received additional psychoeducation. Results: The survival analysis showed significant differences in terms of time to first hospitalization of up to 4-year follow-up: the patients in the psychoeducation group showed a longer time free from hospitalizations than the control group. Concerning the predictors of time to first hospitalization, the only factor that showed a trend to statistical significance was psychoeducation. Conclusions: This is one of few studies assessing the long-term effectiveness of psychoeducation in a naturalistic setting. The data confirm that psychoeducation can impact illness course, in terms of longer time free from hospitalizations. Trial registration: ISRCTN17827459.

Treatment-Resistant Schizophrenia: Genetic and Neuroimaging Correlates.

Schizophrenia is a severe neuropsychiatric disorder that affects approximately 0.5-1% of the population. Response to antipsychotic therapy is highly variable, and it is not currently possible to predict those patients who will or will not respond to antipsychotic medication. Furthermore, a high percentage of patients, approximately 30%, are classified as treatment-resistant (treatment-resistant schizophrenia; TRS). TRS is defined as a non-response to at least two trials of antipsychotic medication of adequate dose and duration. These patients are usually treated with clozapine, the only evidence-based pharmacotherapy for TRS. However, clozapine is associated with severe adverse events. For these reasons, there is an increasing interest to identify better targets for drug development of new compounds and to establish better biomarkers for existing medications. The ability of antipsychotics to improve psychotic symptoms is dependent on their antagonist and reverse agonist activities at different neuroreceptors, and some genetic association studies of TRS have focused on different pharmacodynamic factors. Some genetic studies have shown an association between antipsychotic response or TRS and neurodevelopment candidate genes, antipsychotic mechanisms of action (such as dopaminergic, serotonergic, GABAergic, and glutamatergic) or pharmacokinetic factors (i.e., differences in the cytochrome families). Moreover, there is a growing body of literature on the structural and functional neuroimaging research into TRS. Neuroimaging studies can help to uncover the underlying neurobiological reasons for such resistance and identify resistant patients earlier. Studies examining the neuropharmacological mechanisms of antipsychotics, including clozapine, can help to improve our knowledge of their action on the central nervous system, with further implications for the discovery of biomarkers and the development of new treatments. The identification of the underlying mechanisms of TRS is a major challenge for developing personalized medicine in the psychiatric field for schizophrenia treatment. The main goal of precision medicine is to use genetic and brain-imaging information to improve the safety, effectiveness, and health outcomes of patients via more efficiently targeted risk stratification, prevention, and tailored medication and treatment management approaches. The aim of this review is to summarize the state of art of pharmacogenetic, pharmacogenomic and neuroimaging studies in TRS.

Effectiveness of Cognitive Remediation in Early Versus Chronic Schizophrenia: A Preliminary Report.

Background: Many evidences have demonstrated the effectiveness of cognitive remediation on cognition and functioning in patients with schizophrenia. Some researchers speculate that cognitive deficits are more amenable to remediation during earlier phases of illness than in chronicity. Therefore, cognitive rehabilitation should be used as an early intervention, seeking to produce durable functional changes in the early course of schizophrenia. Although there is strong evidence that cognitive remediation is effective in adult schizophrenia, there is little evidence about its efficacy and long-term generalized effectiveness in the early course of the disease. In this paper, we intended to investigate the possibility that cognitive remediation may produce more beneficial effects when applied in the early phase of the illness compared to chronic patients. Materials and methods: Data were gathered from a database used for a previous study performed by our group, in which 56 patients with schizophrenia received a cognitive remediation intervention. In a post hoc analysis, patients with a duration of illness shorter than 5 years were defined as "early course" patients, while patients with a duration of illness longer than 5 years were defined as "chronic." Clinical, neuropsychological, and functional outcome variables were assessed at baseline and after treatment. Result: Of the 56 patients included in the study, 11 were "early course" and 45 were "chronic." Both the early course group and the chronic group showed significant improvements in all the clinical, neurocognitive, and functional parameters analyzed. A significantly greater improvement in early course patients compared with chronic patients emerged in clinical and functional measures. No differential change was observed between early course patients and chronic patients in the cognitive composite score. Conclusion: Our study confirms the effectiveness of cognitive remediation in improving clinical, cognitive, and functional parameters in patients with schizophrenia, both in patients in the early course and in chronic patients. However, patients in the early course showed a differential, greater change in clinical and functional parameters compared to chronic patients. Although this study has some limitations, it confirms the effectiveness of cognitive remediation interventions, particularly if applied in the early course of the illness.

Paliperidone extended-release in the short- and long-term treatment of schizophrenia.

Paliperidone is a second-generation antipsychotic drug belonging to the class of benzisoxasole derivatives. Paliperidone is the major active metabolite of risperidone (9-OH-risperidone) and, as such, is comparable to the latter in terms of pharmacodynamic properties. However, due to its peculiar characteristics, paliperidone may be particularly useful in the treatment of schizophrenic patients. In this critical review of the literature the efficacy and tolerability in the short- and in the long-term have been evaluated in patients with schizophrenia. Taking into account the tolerability and efficacy data, together with the use of innovative sustained-release formulation, with a peculiar pharmacokinetic profile that allows single daily administration, paliperidone can be considered a valid option both for the short and the long-term treatment of schizophrenia.

Well-being in patients with schizophrenia, mood and personality disorders attending psychiatric services in the community. A controlled study.

BACKGROUND: Poor attention is paid by recent research to the prevalence of mental well-being in psychiatric patients and the comparison between groups with different diagnoses. Data suggest that the presence of mental illness does not necessarily mean the absence of well-being, particularly in stable outpatients. METHODS: A consecutive series of 375 patients attending two community mental health centers was given the Mental Health Continuum Short Form (MHC-SF) and the Clinical Global Impression - Severity scale. Diagnoses were made after the MINI Neuropsychiatric Interview and a chart review of all relevant clinical information. The flourishing category and the three components of MHC-SF were used to rate well-being. A total of 274 controls were taken from the employees at a local firm. RESULTS: The rates of flourishing mental health were: 33.1% schizophrenia, 36.6% bipolar disorder, 23.3% unipolar depression, 24.4% cluster B personality disorder, and 53.3% controls (p < 0.001). The comparison of the three MHC components across diagnostic groups found that unipolar depression and cluster B personality patients had significantly lower scores compared to bipolar and schizophrenia patients. Flourishing mental health was detected more often in males than females (34.9% vs. 24.1% - p < 0.05). For schizophrenia patients indices of well-being were better in those on depot medications. CONCLUSIONS: Psychiatric outpatients with major mental illness have lower rates of well-being compared to controls, although about one-third is flourishing. Patients with unipolar depression and cluster B personality disorder may deserve special attention when planning intervention for fostering well-being.

Paliperidone palmitate in short- and long-term treatment of schizophrenia.

Poor adherence to treatment remains a major problem in the management of patients with schizophrenia. In the 60s, first generation antipsychotics in depot formulation have been introduced on the market with the aim to improve adherence to therapy. However, the limited effectiveness on negative symptoms and the tendency to induce extrapyramidal side effects has limited their use. Currently there are five second-generation antipsychotic long-acting formulations and the use of these drugs has definitely changed perspective: they are no more restricted as compounds intended to improve compliance, but they can be considered first-line drugs with proven efficacy and good tolerability. In this narrative review the efficacy and tolerability of paliperidone palmitate, as well as the economic impact of the use of this particular molecule, have been evaluated in the short- and long-term treatment of schizophrenia. Taking into account the results of different studies, paliperidone, especially in his long-acting formulation, can be considered a viable and effective treatment for patients with schizophrenia, both in the short- and in the long term.

Looking through autistic features in schizophrenia using the PANSS Autism Severity Score (PAUSS).

Autism spectrum disorder (ASD) and schizophrenia share several features. However, the assessment of ASD in schizophrenia is difficult. Aim of this study is to investigate the possibility to use the PANSS Autism Severity Score (PAUSS) to recognize autistic features in schizophrenia. The PAUSS was administered to 75 patients with schizophrenia, previously assessed with ASD diagnostic scales. PAUSS total scores were higher in patients with ASD, compared to those without ASD. Patients with PAUSS score higher than the cut-off proposed for ASD showed specific neuropsychological and functional characteristics. The PAUSS may be useful to identify patients with schizophrenia autistic features.

At-risk gambling in patients with severe mental illness: Prevalence and associated features.

Background and aims The primary objective of this study was to investigate the prevalence of at-risk gambling in a large, unselected sample of outpatients attending two community mental health centers, to estimate rates according to the main diagnosis, and to evaluate risk factors for gambling. Methods All patients attending the centers were evaluated with the Canadian Problem Gambling Index and the Mini International Neuropsychiatric Interview. Diagnoses were checked with the treating psychiatrists and after a chart review of the university hospital discharge diagnoses. Results The rate of at-risk gambling in 900 patients was 5.3%. In those who gambled over the last year, 10.1% were at-risk gamblers. The rates in the main diagnostic groups were: 4.7% schizophrenia and related disorders, 4.9% bipolar disorder, 5.6% unipolar depression, and 6.6% cluster B personality disorder. In 52.1% of the cases, at-risk gambling preceded the onset of a major psychiatric disorder. In a linear regression analysis, a family history of gambling disorder, psychiatric comorbidities, drug abuse/dependence, and tobacco smoking were significantly associated with at-risk gambling. Discussion and conclusion The results of this study evidenced a higher rate of at-risk gambling compared to community estimates and call for a careful screening for gambling in the general psychiatric population.

Factors Associated With Response and Resistance to Cognitive Remediation in Schizophrenia: A Critical Review.

Cognitive impairment is a central feature of schizophrenia and has shown to play a crucial role in the psychosocial function of the disorder. Over the past few years, several cognitive remediation (CR) interventions have been developed for schizophrenia, whose effectiveness has also been widely demonstrated by systematic reviews and meta-analysis studies. Despite these evidences, many questions remain open. In particular, the identification of CR response predictors in patients with schizophrenia is still a topic with equivocal findings and only a few studies have looked for the relationship between CR response or resistance and the biological, socio-demographic, clinical and cognitive features in schizophrenia. The current knowledge on positive or negative response predictors to CR treatment in schizophrenia include: age, duration of illness, premorbid adjustment, baseline cognitive performance, intrinsic motivation, hostility, disorganized symptoms, neurobiological reserve, genetic polymorphisms, the amounts of antipsychotics, the type of CR, etc. The aim of this review is to identify neurobiological, psychopathological, cognitive, and functional predictors of CR response or resistance in schizophrenia, taking into account both cognitive and functional outcome measures. The information obtained could be very useful in planning integrated and personalized interventions, also with a better use of the available resources.

Functional impairment in patients with major depression in clinical remission: results from the VIVAL-D-Rem, a nationwide, naturalistic, cross-sectional survey.

In recent years, the standard for successful treatment of major depression has switched from response to remission; however, little is known about patients who have achieved remission, but still have some residual symptoms and whether they regain previous levels of functioning. In a large, nationwide, cross-sectional, naturalistic survey (VIVAL-D) of 907 patients with major depression treated with a new course of an antidepressant in 41 Italian community psychiatric centers, patients with a Hamilton Rating Scale for Depression, 17-item version (HAM-D17) score up to 14 were selected (n=499). Of these, 169 were considered to be in remission (HAM-D17 ≤ 7) and the other 330 to be mildly depressed. Their level of functioning was evaluated using the SF-12. Only a few (3%) patients in remission were completely symptom free; most were affected by residual symptoms. Patients in remission had better SF-12 scores than those with mild depression, but their functioning was significantly worse than general population norms. In the logistic regression analysis, the HAM-D17 total score and individual items were predictive of poor functioning. Analysis of sensitivity and specificity values showed that a lower cut-off score (4/5) of the HAM-D17 scale was best for predicting poor performance so that a reconsideration of the usual cut-off for remission of 7/8 for HAM-D17 seems overdue.

Functional disability and death wishes in older Europeans: results from the EURODEP concerted action.

PURPOSE: Physical illness has been shown to be a risk factor for suicidal behaviour in older adults. The association between functional disability and suicidal behaviour in older adults is less clear. The aim of this study was to examine the relationship between functional disability and death wishes in late life. METHODS: Data from 11 population studies on depression in persons aged 65 and above were pooled, yielding a total of 15,890 respondents. Level of functional disability was trichotomised (no, intermediate, high). A person was considered to have death wishes if the death wish/suicidal ideation item of the EURO-D scale was endorsed. Odds ratios for death wishes associated with functional disability were calculated in a multilevel logistic regression model. RESULTS: In total, 5 % of the men and 7 % of the women reported death wishes. Both intermediate (OR 1.89, 95 % CI 1.42; 2.52) and high functional disability (OR 3.22, 95 % CI 2.34; 4.42) were associated with death wishes. No sex differences could be shown. Results remained after adding depressive symptoms to the model. CONCLUSIONS: Functional disability was independently associated with death wishes in older adults. Results can help inform clinicians who care for older persons with functional impairment.

Cerebrovascular accidents in elderly people treated with antipsychotic drugs: a systematic review.

After 2002, an association between stroke and antipsychotic use was reported in clinical trials and large database studies. This review considers previous quantitative reviews, newly published clinical trials, and recent observational cohort and case-control studies, and focuses on the clinical significance of the risk for stroke, the difference between typical and atypical antipsychotics, the possible at-risk patient profile and the timing of stroke after exposure. A search of MEDLINE covering the period from 1966 to June 2009 was carried out using selected keywords. Inclusion criteria were (i) quantitative reviews on stroke and antipsychotics; (ii) double-blind, placebo-controlled clinical trials involving patients with dementia treated with antipsychotics; and (iii) observational database cohort studies and observational case-control studies investigating the association between stroke and antipsychotics. Clinical trials were excluded if they were single-blind or if patients were affected by dementia and/or other neurological illnesses. Four reviews with aggregate data, 2 meta-analyses, 13 randomized, double-blind, controlled trials, 7 observational cohort studies and 4 observational case-control studies were selected and analysed. The incidence of cerebrovascular accidents (CVAs) was found to be very low in aggregate reviews and meta-analyses (2-4%). When the number collected was sufficiently high, or different drug treatments were grouped together, the higher rate in subjects exposed to antipsychotics was statistically significant. Inspection of other randomized controlled clinical trials, not included in aggregate reviews and meta-analyses, reported similar rates of CVAs. The majority of observational cohort studies compared typical and atypical antipsychotics and no significant class differences were found. A comparison with non-users was carried out in some cohort studies. In case-control studies, the probability of CVAs in users compared with non-users was in the range of 1.3- to 2-fold greater. Preliminary data also indicate that the highest risk of stroke is related to the first weeks of treatment, and a risk profile for stroke is emerging, such as older age, cognitive impairment and vascular illness. Different pathophysiological pathways may be involved, ranging from the facilitation of thrombosis, pre-existing cardiovascular factors, sedation and a common diathesis for stroke of dementia, schizophrenia and affective illness. Before prescribing an antipsychotic, clinicians should weigh all the risk factors for a given patient and consider not only the indications as provided by the regulatory agencies, but also the overall effectiveness of typical and atypical antipsychotics.

Risk of stroke with typical and atypical anti-psychotics: a retrospective cohort study including unexposed subjects.

The purpose of the study was to investigate the risk of stroke with typical and atypical anti-psychotics in elderly subjects, weighting for a number of known risk factors, including dementia. Data were retrospectively drawn from the primary care setting from the Health Search Database, which stores information on about 1.5% of the total Italian population served by general practitioners. All elderly patients (65+ years) prescribed an anti-psychotic in monotherapy from January 2000 to June 2003 were selected for the study. A cohort of patients not exposed to anti-psychotics was taken from the same database. Subjects who had previously had a stroke were excluded. The main outcome measure was the incidence of first-ever stroke during exposure to an anti-psychotic.The sample included non-users (69,939), users of atypicals (599), butyrophenones (749), phenotiazines (907) and substituted benzamides (1,968). The crude incidence of stroke in subjects not exposed to anti-psychotics was 12.0/1000 person-years. Risk was significantly higher for those on butyrophenones (47.1/1000), phenotiazines (72.7/1000) and in the atypical anti-psychotic group (47.4/1000). Substituted benzamides had an almost significant higher risk (25.0/1000). Cox regression modelling, weighting for demographic and clinical variables with non-users as the reference group, showed that the risk for stroke was 5.79 times for phenotiazines, 3.55 times for butyrophenones, and 2.46 times for atypicals. Clinicians should be cautious in prescribing phenotiazines and butyrophenones in elderly patients, since the risk for stroke would seem comparable or even greater than with atypicals.

Immediate and 8-month impact of a medical educational course for general practitioners on knowledge about schizophrenia and its treatment: results of a 3-phase study from Brescia, Italy.

OBJECTIVE: To test the efficacy of a training course on the diagnosis and treatment of schizophrenia, tailored for the general practitioner. METHOD: A course, in a 3-session format, was given to 215 primary care doctors from the city of Brescia and its province, in Italy. All 706 doctors working in primary care were asked to participate. Of these doctors, 30.5% took part in the study. The first session (215 doctors) assessed baseline knowledge of schizophrenia (June 2002), the second (173 doctors) gave formal teaching and assessed post-lesson knowledge (October 2002), and the third (130 doctors) evaluated the retention of knowledge after 8 months (July 2003). The main outcome measures were total number of schizophrenia symptoms identified, total number of antipsychotics identified, and knowledge about antipsychotic-related adverse events. RESULTS: Post-lesson, general practitioners could identify 6.5 more symptoms (p < .001) and 4.9 more antipsychotics (p < .001). Compared to baseline, 71.5% vs. 15.4% of doctors had a good knowledge of antipsychotic-related adverse events. Although a loss of knowledge was found after the 8-month follow-up, knowledge at the endpoint was significantly higher than at baseline for the 3 main outcome variables (p < .001). CONCLUSION: The teaching course on schizophrenia for general practitioners was effective, and the knowledge gained after teaching was stable across time.

Variables associated with general practitioners' knowledge about and diagnostic skills for schizophrenia.

OBJECTIVE: This study investigated the level of knowledge about schizophrenia of primary care doctors working in the city of Brescia, Italy, and variables associated with better information. METHOD: The study design was devised after 2 joint meetings with leading figures of the Italian College of General Practitioners. A cross-sectional evaluation of 215 general practitioners was performed (June 2002). A random subgroup was selected to participate in a 4-month retest session in order to evaluate the reliability of the schedule (October 2002). The setting was the local health unit of Brescia, which involves 706 primary care doctors working in the city and its province. Of these, 30.5% took part in the study. A structured self-report questionnaire (SAKS) was devised for this study. General practitioners were also asked to rate videotaped cases of 5 patients with different DSM-IV diagnoses. The main outcome measures were the scores from subscales measuring knowledge of schizophrenia symptoms and signs, knowledge of antipsychotics and their adverse events, and correct diagnoses of 5 videotaped cases. RESULTS: Primary care doctors identified positive (79.0%), negative (72.6%) and general (72.1%) symptoms of schizophrenia (p < .001). Of the 5 cases on videotape, they correctly rated a mean of 3.1 cases. The mean percentage of anti-psychotics correctly identified was 34.1% (older) and 51.2% (novel) (p < .001). Better answers were given by doctors who knew the diagnostic criteria, had read books on psychiatry, and had attended previous courses. CONCLUSION: More teaching on the diagnosis of schizophrenia and clinical psychopharmacology should be given to general practitioners.
