- Background: Patients diagnosed with schizophrenia display poor premorbid adjustment (PPA) in half of the cases. Attention deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) are common child psychiatric disorders. These two facts have not previously been linked in the literature. Aims: To determine the prevalence of ADHD/CD problems retrospectively among patients with psychoses, and whether and to what extent the high frequency of substance abuse problems among such patients may be linked to ADHD/CD problems. Method: ADHD and CD problems/diagnoses were retrospectively recorded in one forensic (n = 149) and two non-forensic samples (n = 98 and n = 231) of patients with a psychotic illness: schizophrenia, bipolar or other, excluding drug-induced psychoses. Results: ADHD and CD were much more common among the patients than in the general population-the odds ratio was estimated to be greater than 5. There was no significant difference in this respect between forensic and non-forensic patients. Substance abuse was common, but substantially more common among patients with premorbid ADHD/CD problems. Conclusions: Previous views regarding PPA among patients with a psychotic illness may reflect an association between childhood ADHD/CD and later psychosis. The nature of this association remains uncertain: two disorders sharing some generative mechanisms or one disorder with two main clinical manifestations. Childhood ADHD and particularly CD problems contribute to the high frequency of substance abuse in such groups.

- The abuse of flunitrazepam (FZ) compounds is worldwide, and several studies have reflected on the consequences with regard to violence, aggression and criminal lifestyle of FZ users. Criminals take high doses of FZ or some other benzodiazepines to "calm down" before the planned crime. There is support from earlier studies that most likely, all benzodiazepines may increase aggression in vulnerable males. Chronic intake of high doses of FZ increases aggression in male rats. Because psychopathy involves aggression, we have examined whether psychopathy as well as any of the four facets of the Psychopathy Checklist-Revised (PCL-R) (Interpersonal, Affective, Lifestyle and Antisocial) are related to different substance use disorders, with the focus on FZ. We have also examined the relationship between each PCL-R item and FZ use. Participants were 114 male offenders aged 14-35 years, all of whom were convicted for severe, predominantly violent, offences. Substance use, including FZ, was not more common in those who scored high in psychopathy. Use of FZ was more common in offenders who scored high in Facet 4 (Antisocial) of the PCL-R (odds ratio = 4.30, 95% CI 1.86-9.94). Only one of the PCL-R items, "Criminal versatility", was significantly associated with FZ use (odds ratio = 3.7). It may be concluded that intake of FZ has a specific relationship to only one of the facets and not to psychopathy per se. ; The findings have also important theoretical implications because Facet 4 is not a key factor of the construct of psychopathy. Clinical implications of the article: We have used the new two-factor and four-facet theoretical model of psychopathy in the young offender population, many of them with one or more substance use disorders. The present results suggest that antisocial behavior defined by Facet 4 (poor behavioral control, early behavior problems, juvenile delinquency, revocation of conditional release and criminal versatility) in the studied subjects is more typical for FZ users than it is for non-FZ users. This may have implications for assessment and treatment. Clinicians should be aware that criminals with high scores on Facet 4 have a more than fourfold odds of being a FZ user. This conclusion has an important clinical implication because FZ abuse is very common and is not always the focus of a forensic psychiatric assessment. ;

- The objective of the study was to validate a self-administrated symptom rating scale for use in patients with schizophrenia spectrum disorders by item analysis, exploration of factor structure, and analyses of reliability and validity. Data on 151 patients, initially treated by risperidone, obtained within the framework of a naturalistic Phase IV longitudinal study, were analysed by comparing patient and clinician ratings of symptoms, side-effects and global indices of illness. The Symptom Self-rating Scale for Schizophrenia (4S) is psychometrically adequate (item analysis, internal consistency, factor structure). Side-effect ratings were reliable. Symptom ratings displayed consistent associations with clinicians' ratings of corresponding symptom dimensions, suggesting construct validity. Patients had most difficulties assessing negative symptom items. Patients were well able to assess their own symptoms and drug side-effects. The factor structure of symptom ratings differs between patients and clinicians as well as how they construe global indices of illness. Clinicians focus on psychotic, patients on affective symptoms. Use of symptom self-ratings is one way to improve communication and thereby strengthen the therapeutic alliance and increase treatment adherence.

Tidskriftsartikel (refereegranskat)abstract
- Background: Symptom control by drug treatment is the most important task in routine clinical care of patients with schizophrenia. Structured assessment methods are needed in this task but not used much. The US-developed Positive and Negative Syndrome Scale (PANSS) is a standard tool for symptom assessment. The Psychosis Evaluation tool for Common use by Caregivers (PECC) was constructed in Europe some years ago, with the intent to overcome some of the PANSS drawbacks. Aims and methods: To validate PECC on three longitudinal cohorts of schizophrenic patients representative of Swedish outpatients (n = 225, six assessments over 5 years), international forensic patients (n = 186) and matched non-forensic controls (n = 116), five assessments over 2 years for both. Results: The factor structure of PECC appears to be highly robust. Norm values (in percentiles) were calculated on the materials. Such data provides for analyses of symptom profiles and improvement over time measured in absolute numbers. Forensic patients appear to have a much lower symptom load (except for cognitive symptoms) than the other groups. Forensic controls had much shorter inpatient times than any other group and never caught up with respect to symptom control, even after 2 years. These differences suggest that the scale is clinically valid. Conclusion: PECC has a more robust factor structure than PANSS and is simpler to use. Percentile norms have been constructed for outpatients with schizophrenia in general and forensic psychiatry. Percentile scores are accessed readily by the net. PECC is available in many languages. Its separate self-harm item may improve assessments of suicide risk among patients with schizophrenia

- Objective: To investigate a series of consecutive suicides at a psychosis clinic by using a psychological autopsy technique. Method: The clinic serves an adult population of 225,000 individuals, of whom 0.5% have regular contact with the clinic. During a 7½-year period, 23 men and nine women committed suicide, which corresponds to an odds ratio of 14. Results: Most patients were schizophrenic, and 24 were outpatients. Suicide methods were violent in all but two cases. Nineteen had a history of at least one suicide attempt, and 24 were known to have had suicidal ideation. More than half had no social contacts over the last year except with psychiatric staff. The median time between the last contact with the psychiatric services and the suicide was 4 days. No warning signs were noted. At the time of death, 3 of the 24 who were prescribed antipsychotics, and none of the 10 who were prescribed antidepressants had plasma levels of the corresponding drug. Conclusion: Findings of special interest are the lack of forewarnings and the poor drug compliance. Patients appear to have played "business as usual" with the care-givers, and did it well. Is it a sign of health and despair, or illness?

- Objective: To investigate the association between the Positive and Negative Syndrome Scale (PANSS) cognitive factors and cognition assessed by neuropsychological tests. Method: Ninety patients with a psychotic illness, the majority having a schizophrenia diagnosis, were assessed with PANSS ratings and tested by a comprehensive computerized neuropsychological test battery, EuCog. Results: Test performance was in the normal range for some of the cognitive indices, but substantially reduced for others, compared with norms, particularly speed-based indices. PANSS ratings were non-specifically associated with cognitive indices representing performance (speed and accuracy) and problem solving strategies (executive functions). There was no discriminant validity for the cognitive factor. A regression analysis suggested that the PANSS cognitive factors reflected verbal IQ but no other cognitive domain like memory, attention or speed. Conclusion: Cognitive test performance is associated with psychopathology as assessed by PANSS items but in a non-specific way. The PANSS cognitive subscale seems to reflect over-learned verbal skills rather than the cognitive domains, which are known to be specifically affected in schizophrenia and relevant for the prognosis. Consequently, PANSS ratings cannot replace the information inherent in neuropsychological test data. The extensive speed problem of patients with schizophrenia should be studied in more detail using test batteries that focus on that problem.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The de-institutionalizing process came to an end before the millennium shift by closing mental hospitals. After that some of the most ill patients are cared for in sheltered housing (SH). There is no in-house psychiatric competence and the staff on the floor usually lacks such knowledge and training. Observation instruments may improve this by making it possible to assess and monitor patients. Method: FAST-O is a simple twelve-item observation scale. Staff at eight SH units were trained in using the instrument and then assessed a total of 67 patients once, twice or three times at monthly intervals. Results: Ten items formed two highly homogenous subscales reflecting Social skills (Soc) and Excitation/Aggression (E/A). Depression and Clinical Global Impression (CGI) items were considered separately. The correlation pattern suggested that the ratings had construct validity. A cluster analysis identified three patient subgroups, of which one had very high E/A scores. Comparisons with reference data suggested that the average symptom level was on par with acutely admitted in-patients for this subgroup. In all groups, E/A symptoms varied considerably over time, the other symptoms were more stable. There were marked differences among the eight SH units with respect to the level of patient problems. Conclusions: The SH staff was able to produce valid FAST-O assessments. There are reference data which makes it possible to characterize individual patients as well as SH units with respect to treatment needs and safety aspects (for instance risk of violence).
