- The aim of the present study was to evaluate the psychometric properties of the parallel client and clinician versions of the Illness Management and Recovery Scale (IMRS) developed to monitor the clients' progress in the Illness Management and Recovery (IMR) program in schizophrenia. A total of 107 study participants completed assessments of the IMRS, interview-based ratings of psychiatric symptoms, self-ratings of psychiatric symptoms, perception of recovery, and quality of life. Case managers completed the clinician version of the IMRS. Both versions of the scale demonstrated satisfactory internal reliability and strong test-retest reliability. The results also indicated convergent validity with interview-based ratings of psychiatric symptoms, self-rated symptoms, perception of recovery, and quality of life for both versions of the IMRS. These findings support the utility of the IMRS as a measure of illness self-management and recovery in clients with schizophrenia.

- Patients with schizophrenia have an average lifespan approximately 20 years shorter than the normal population. This study explored if there were any specific common characteristics among patients with schizophrenia spectrum disorder who died prematurely, compared to those who survived or died at a more normative age. The data were obtained from an ongoing twenty-year longitudinal study wherein 67 patients out of 501 participants had died at an average age of 60.5 years. Differences in baseline assessments of symptoms and cognitive ability were compared across patients who died during the time of the study and survivors. Symptom remission was assessed according to the Andreasen remission criteria as presented in 2005. Cognitive performance was assessed with a battery of instruments measuring vigilance, working memory, learning, short-term memory, and executive function. Two patients committed suicide and together they lowered the average lifespan of the study sample by only 0.27 years. The baseline assessments showed no difference in symptoms or remission status between patients who died and those who survived. This finding was in contrast to the cognitive baseline assessments where it was found that those who had died had performed more poorly in multiple domains, especially executive functioning, cognitive flexibility, learning and short-term memory. Survival analysis with Cox models showed that verbal memory and executive functioning were the most substantial independent predictors. Our study shows that although suicide was not a common cause of death, the average age of death is still young for this patient group and cannot be explained by differences in symptom severity. Our findings indicate that cognitive abilities might be of special interest for affective longevity in patients with schizophrenia, either as a marker of special risk or as a target for direct intervention.

- Background Sibship size and birth order may be contributing factors to the multifactorial etiology of psychosis. Specifically, several studies have shown that sibship size and birth order are associated with schizophrenia. However, there are no studies on their association with psychotic experiences (PE). Methods Cross-sectional, community-based data from 43 low- and middle-income countries which participated in the World Health Survey were analyzed. The Composite International Diagnostic Interview was used to identify four types of past 12-month PE. The association of sibship size and birth order with PE was assessed with multivariable logistic regression. Results The final sample consisted of 212,920 adults [mean (SD) age 38.1 (16.0) years; 50.7% females]. In the multivariable analysis, compared to individuals with no siblings, the OR increased linearly from 1.26 (95%CI = 1.01–1.56) to 1.72 (95%CI = 1.41–2.09) among those with 1 and ≥ 9 siblings, respectively. Compared to the first-born, middle-born individuals were more likely to have PE when having a very high number of siblings (i.e. ≥9). Conclusions Future studies should examine the environmental and biological factors underlying the association between sibship size/birth order and PE. Specifically, it may be important to examine the unmeasured factors, such as childhood infections and adversities that may be related to both family structure and PE.

Tidskriftsartikel (refereegranskat)abstract
- Background: Information on the association between subclinical psychosis and pain is scarce, and the role of common mental disorders (CMDs) in this association is largely unknown. The aim of the current study was to therefore assess this association in the general population using nationally representative data from England. Methods: Data for 7403 adults aged. ≥. 16. years were used from the 2007 Adult Psychiatric Morbidity Survey. Five forms of psychotic symptoms were assessed by the Psychosis Screening Questionnaire, while pain was assessed in terms of the level of its interference with work activity in the past four weeks. The Clinical Interview Schedule Revised (CIS-R) was used to assess anxiety disorders, depressive episode, and mixed anxiety-depressive disorder (MADD). Participants with probable or definite psychosis were excluded. The association between psychotic symptoms and pain was assessed by ordinal and binary logistic regression analysis. Results: When adjusted for confounders other than CMDs, psychotic symptoms were significantly associated with pain [e.g., the OR (95%CI) for the severest form of pain (binary outcome) was 1.78 (1.11-2.85)]. However, this association was no longer significant when CMDs were controlled for in most analyses. Anxiety disorders and depressive episode explained 34.8%-47.1% of the association between psychotic symptoms and pain, while this percentage increased to 62.7%-78.0% when the sub-threshold condition of MADD was also taken into account. Conclusions: When coexisting psychotic symptoms and pain are detected, assessing for anxiety and depression (even at sub-threshold levels) may be important for determining treatment options.

- Background: Psychotic disorders have been associated with suicidality but information on the association between subclinical psychosis and suicidality in the general adult population is scarce. Methods: Data from the 2007 Adult Psychiatric Morbidity Survey (n = 7403) were analyzed. This was a nationally representative survey of the English adult household population (aged ≥. 16. years). Five types of psychotic symptoms (hypomania, thought control, paranoia, strange experience, auditory hallucination) occurring in the past 12. months were assessed with the Psychosis Screening Questionnaire. Participants with probable or definite psychosis were excluded. Logistic regression analysis was used to assess the association between psychotic symptoms and suicidal ideation and suicide attempt in the past 12. months. Results: The prevalence of at least one psychotic symptom was 5.4%. After adjusting for potential confounders including mental disorders, each individual psychotic symptom was significantly associated with suicidal ideation with odds ratios (ORs) ranging from 3.22 to 4.20. With the exception of thought control, all symptoms were also associated with significantly higher odds for suicide attempt (ORs 3.95 to 10.23). Having at least one psychotic symptom was associated with ORs of 3.13 (95%CI 2.09-4.68) and 3.84 (95%CI 1.67-8.83) for suicidal ideation and suicide attempt respectively. In addition, a greater number of psychotic symptoms was associated with higher odds for suicidal ideation and suicide attempt. Conclusions: Psychotic symptoms, regardless of the type, were independently associated with higher odds for suicidal ideation and suicide attempt. Assessment and management of suicide risk in individuals with psychotic symptoms may be important for suicide prevention.

- Social cognition impairments are well described in both autism spectrum disorders, including Asperger syndrome (AS), and in schizophrenia spectrum disorders. However, little is known about whether there are differences between the two groups of disorders regarding this ability. The aim of this study was to compare social cognition abilities in AS and schizophrenia. Fifty-three individuals (26 men, 27 women) with a clinical diagnosis of AS, 36 (22 men, 14 women) with a clinical diagnosis of schizophrenic psychosis, and 50 non-clinical controls (19 men, 31 women) participated in the study. Clinical diagnoses were confirmed either by Structured Clinical Interview on DSM-IV diagnosis or the Diagnostic Interview for Social and Communication Disorders. Verbal ability was assessed using the Vocabulary subtest of the WAIS-III. Two social cognition instruments were used: Reading the Mind in the Eyes Test (Eyes Test) and the Animations Task. On the Eyes Test, patients with schizophrenia showed poorer results compared to non-clinical controls; however, no other group differences were seen. Both clinical groups scored significantly lower than the comparison group on the Animations Task. The AS group performed somewhat better than the schizophrenia group. Some differences were accounted for by gender effects. Implicit social cognition impairments appear to be at least as severe in schizophrenia as they are in AS. Possible gender differences have to be taken into account in future research on this topic.

- Patients with schizophrenia have significantly greater mortality rates than the general population, with an estimated reduced lifespan of 10-20 years. We previously reported on a link between impairment in cognition and premature death in a prospective 20-year study. Patients who had died prematurely showed neurocognitive impairment in nine different cognitive tests compared to those who did not. Based on those findings, in this study the surviving patients in the cohort were divided into three different groups based on neurocognitive impairment and compared on symptom severity including remission status, RAND-36, weight and BMI at onset of illness and baseline of the study, and medical/physical symptomatology (i.e., blood pressure, symptom awareness, vertigo and orthostatic symptoms). Differences were most prominent between the cognitively unimpaired and severely cognitively impaired (SCI) groups, with remission, negative symptoms, general symptoms and PANSS total scores differing. For SF-36 (RAND) Physical functioning and Role limitations due to physical health subscales the SCI were worst. The findings indicate that greater impairments in cognitive ability during the illness are associated with several potential indicators of risk for early mortality. Together these factors may be of guidance for establishing an algorithm to detect patients at risk of premature death early in their illness. (C) 2018 Elsevier B.V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- People with schizophrenia often demonstrate an impaired ability to assess and report aspects of their everyday functioning, and the aim of this study is to investigate how patients' self-rating ability regarding functional performance relates to neurocognitive performance and real-world functional performance. A total of 222 outpatients with a schizophrenia spectrum disorder participated in this study. They were divided into groups based on their self-rating ability (determined using self-rating questions) and their observed functional capacity (the UCSD Performance-Based Skills Assessment-Brief, UPSA-B). The results showed that patients with impaired functional capacity perform at a similar cognitive level, regardless of their self-rating ability. When comparing patients with unimpaired function to those with impaired function, we found differences in two cognitive domains; premorbid functioning and executive functioning. The results also reveal that clinicians seem to have greater difficulty assessing patients who over-estimate their functioning. Consequently, when clinicians assessed the patients with the Specific Levels of Functioning Scale (SLOF) no significant differences were found between the group with unimpaired function and the group of overestimators. Patients who overestimate their functioning risk receiving inadequate treatment and support.
