We describe adolescents' perpetration of sibling aggression and its link to physical health two years later. In-school surveys at Time 1 (N = 331) and Time 2 (two-years later, N = 283) were administered to adolescents (at Time 1, Mage = 15.71 years, SD = .63; 52% female) living in the United States querying about perpetration of aggression toward a sibling closest in age and perceived physical health. The majority of adolescents perpetrated aggression towards their sibling (74%). Adolescents who were part of brother–brother pairs reported the most aggression. Hierarchical regression analysis showed that perpetrating sibling aggression more often at Time 1 was predictive of lower physical health at Time 2 controlling for Time 1 physical health and demographic characteristics. Perpetration of aggression toward a sibling is common and has negative health consequences in late adolescence suggesting this issue should be targeted to improve adolescents' sibling dynamics and physical health. 相似文献

Increasing evidence supports the role of childhood trauma in the etiology of psychosis but underlying mechanisms are poorly understood. Early maltreatment has been linked to dissociative symptoms in psychosis patients. We explored associations between childhood trauma (Childhood Trauma Questionnaire) and dissociation (Dissociative Experiences Scale) in first-episode psychotic patients (n=62), chronic psychotic patients (n=43), and non-psychotic community controls (n=66). Multivariate analyses of covariance were used to test associations between childhood trauma and dissociation by group while controlling for sex. Chronic patients reported the highest level of dissociation. More severe childhood trauma was associated with greater dissociative symptoms in all groups although most strongly in chronic patients. Emotional abuse showed the strongest associations with dissociation, with these being strongest for chronic patients, followed by first-episode patients — and least for controls. Men showed a stronger association between physical neglect and dissociation than women, irrespective of group. There were no significant group by sex interactions. Our findings replicate the strong association between childhood trauma and dissociative symptoms in chronic and first-episode psychotic patients relative to non-psychotic control subjects. We also demonstrate the salience of emotional abuse in explaining variance in dissociation, especially in chronic patients. 相似文献

Two‐phase mental health screening methods, in which an abridged mental health measure is used to establish who should receive a more comprehensive assessment, may be more efficient and acceptable to respondents than a stand‐alone complete questionnaire. Such two‐phase methods are in use in US armed forces post‐deployment mental health screening. This study assesses the sensitivity and specificity of abridged instruments (used in the first phase) compared to the full instruments (the second phase), and whether false negative cases resulting from the use of abridged tests were detected by another test, among a UK military screening sample. Data from a group of UK Armed Forces personnel (n = 1464) who had completed full questionnaires assessing symptoms of post‐traumatic stress disorder (PTSD) (PTSD Checklist – Civilian Version, PCL‐C) and alcohol misuse (Alcohol Use Disorder Identification Test, AUDIT) were used. An abridged version of the PCL‐C performed well in discriminating potential PTSD cases (as measured by the full instrument); AUDIT showed less discriminatory power, particularly due to poor specificity. Many cases missed by one abridged test would have been detected by an alternative test. Thus two‐phase screening designs reduce the resource burden of a project without substantial loss of sensitivity for PTSD, but are less effective in discriminating potential cases of alcohol misuse.

Background There is an increased prevalence of physical illness and poor lifestyle in patients with chronic schizophrenia. It is unclear
whether these are present at the onset of psychosis or develop over the course of illness. We aimed to establish whether patients
experiencing their first episode of psychosis have worse physical health and lifestyle than community controls without psychosis.
Method Eighty-nine patients with new onset illness were compared to age and sex matched controls for self-reported physical illness
and cardiovascular and respiratory risk factors.
Results Patients reported more physical health complaints, mainly respiratory, compared with age and gender matched controls (odds
ratio 2.85, 95% confidence interval 1.2–6.7). Patients were more likely to be cigarette smokers (1.82, 95% CI 1.0–3.3) and
eat a fast food diet (1.04, 95% CI 1.0–1.1), but these differences were accounted for by patients’ unemployment status.
Conclusions Some risk factors for physical health problems are present at the onset of psychosis, but these may be explained by unemployment. 相似文献

Background Evidence suggests that mental health literacy among the public is low, and stigmatizing attitudes are widespread. So far the effects of anti-stigma campaigns are small, and studies demonstrate that negative attitudes have been quite stable through recent decades. Aims To investigate the relationships between mental health literacy, experience of mental illness and stigmatizing attitudes/social distance towards people with depression or psychosis. Methods A cross-sectional study in which staff members from public services in Sweden (n?=?1027) completed questionnaires covering demographic data, self-reported experience of mental illness, identification of a vignette for depression or psychosis, beliefs about helpful interventions for the illness presented in the vignette, and attitudes and social distance towards people with the illness. Results About 50% of participants could identify depression and less than 40% psychosis. A higher degree of mental health literacy was related to less stigma and social distance but mainly towards people with depression. A similar relationship was shown for having personal or family experience of mental illness and attitudes/social distance. Negative attitudes and social distance were significantly higher in all aspects measured towards a person with psychosis than a person with depression. Conclusions A higher degree of mental health literacy relates to more positive attitudes and less desire for social distance towards people with depression. The differences between depression and psychosis should be taken into account in anti-stigma interventions. 相似文献

Several studies suggest hearing impairment as a risk factor for psychosis. Hearing impairment is highly prevalent and potentially reversible, as it can be easily diagnosed and sometimes improved. Insight in the association between hearing impairment and psychosis can therefore contribute to prevention of psychosis. This paper provides meta-analyses of all epidemiologic evidence on the association between hearing impairment and psychosis and summarizes mechanisms that potentially underlie this relationship.Meta-analyses showed an increased risk of hearing impairment on all psychosis outcomes, such as hallucinations (OR 1.40(95%CI 1.18–1.65; n = 227,005)), delusions (OR 1.55(95%CI 1.36–1.78; n = 250,470)), psychotic symptoms (OR 2.23(95%CI 1.83–2.72; n = 229,647) and delirium (OR 2.67(95%CI 2.05–3.48; n = 12,432). Early exposure to hearing impairment elevated the risk of later development of schizophrenia (OR 3.15(95%CI 1.25–7.95; n = 50,490)).Potential mechanisms underlying this association include loneliness, diminished theory of mind, disturbances of source monitoring and top-down processing and deafferentiation. Early assessment and treatment of hearing impairment in patients with (high risk of) psychosis may be essential in psychosis treatment and prevention. 相似文献

Knowledge on associations between ultra-high risk (UHR) for developing psychosis and on non-psychotic psychopathology in help-seeking populations is limited with respect to differences between male and female patients. The present study tests the hypothesis that both social anxiety and depression are highly prevalent in an UHR population, particularly among women. From February 2008 to February 2010 baseline data were collected from help-seeking subjects (14–35 years) who were included in the Dutch Early Detection and Intervention Evaluation (EDIE-NL) trial. Two recruiting strategies were used: a two-stage screening strategy in a population of consecutive help-seeking and distressed subjects of secondary mental health services, and a referral strategy. This study included 201 patients with a mean age of 22.7 years. Of these, 102 (51%) were female, 58% of the patients met the criteria for clinical depression on the Beck Depression Inventory and 42% met the criteria for clinical social phobia on the Social Interaction Anxiety Scale. Women showed more depression and social anxiety than men. The results support the hypothesis that UHR is associated with depression and social anxiety, particularly in women. Screening a help-seeking population with depression and anxiety may be effective in detecting patients at UHR for developing psychosis. 相似文献

Background
We evaluated whether (1) a diagnosis of obsessive-compulsive disorder (OCD) at baseline, or (2) the persistence, remission or emergence of de novo OCD at follow-up, were associated with the development of different psychotic disorders in a cohort of individuals at ultra-high risk (UHR) for psychosis.Methods
Patients were assessed for OCD at baseline and after a mean of 7.4 years follow-up and classified into: (i) Non-OCD group - patients without OCD both at baseline and follow-up (n = 269; 86.2%), (ii) Incident OCD group - patients without OCD at baseline but with OCD at follow-up (n = 17; 5.4%), (iii) Remitting OCD group - patients with OCD at baseline but without OCD at follow-up (n = 20; 6.4%), (iv) Persistent OCD group - patients with OCD both at baseline and at follow-up (n = 6; 1.9%). Rates of different DSM-IV psychotic disorders at follow-up were compared across these groups.Results
Patients who displayed remitting OCD were not related to the development of any DSM-IV psychotic disorder. A diagnosis of incident OCD was associated with greater rates of psychotic disorders at follow-up, particularly mood disorders with psychotic features and psychotic disorders not otherwise specified (PDNOS), and greater baseline severity of general psychopathology, alogia, and avolition-apathy. Two of the six patients (40%) with persistent OCD developed schizophrenia, while only 12.5%, 5.0%, and 9.7% of incident, remitting, and non-OCD groups, respectively, exhibited the same condition at follow-up. Rates of antipsychotic use in the previous two years were not significantly different between the groups.Conclusions
Our findings suggest that, in a cohort of individuals at UHR for psychosis, remission of OCD does not increase the risk of psychosis, while de novo OCD was associated with development of mood disorders with psychotic features and PDNOS. 相似文献10.

PURPOSE: To ascertain whether bimodal psychosis (i.e., independent postictal and interictal psychosis) in patients with epilepsy can be characterized by postictal psychosis that develops after interictal psychosis remits. Methods: We reviewed the records of 14 patients with bimodal psychosis treated at a national center hospital.Clinical and psychopathological characteristics of the patients were examined. RESULTS: Among the 14 patients with bimodal psychosis, four initially had interictal psychosis, and 10 initially had postictal psychosis. That is, interictal-antecedent bimodal psychosis characterized four cases, and postictal-antecedent bimodal psychosis characterized 10 cases. Patients with interictal-antecedent bimodal psychosis composed 2.2% of the total patients with epilepsy and psychosis (n = 180) and 28.5% of total patients with bimodal psychosis. All four patients with interictal-antecedent bimodal psychosis had partial epilepsy with complex partial seizures, bilateral EEG abnormalities, and borderline (or decreased) intellectual functioning. Most of these clinical features are common to both types of bimodal psychosis. Among patients with interictal-antecedent bimodal psychosis, the mean age at the onset of the initial symptoms was 10.8 years (SD, 4.3 years) for epilepsy, 24.4 (6.1) years for interictal psychosis, and 33.8 (4.5) years for postictal psychosis. CONCLUSIONS: In a few patients, postictal psychosis develops after the remission of interictal psychosis. Interictal-antecedent bimodal psychosis is not likely a discrete entity because of several characteristics common to both types of bimodal psychosis. Patients may have greater vulnerability to psychosis and develop psychotic episodes easily, regardless of the presence of preceding seizures. 相似文献

BackgroundChildhood trauma has been associated with a more severe clinical expression of bipolar disorder (BD). However, the results that specifically associated traumatic events and psychotic features in BD have been inconsistent, possibly due to the low resolution of the phenotypes being used.Methods270 normothymic patients with BD completed the Childhood Trauma Questionnaire (CTQ) and the Peters Delusion Inventory (PDI) that assessed 21 delusional beliefs. Patients were characterized for the lifetime presence of psychotic features during episodes and cannabis misuse in accordance with DSM-IV. We performed a series of path analyses to investigate the links from three types of childhood abuse (physical, sexual and emotional) directly to delusional beliefs and psychotic features, and indirectly through cannabis misuse.ResultsA first path analysis showed no link between any of the childhood abuse types and psychotic features when only a categorical definition of psychosis was used. When incorporating the quasi-dimensional measure of delusional beliefs in a second path analysis, we found that emotional and physical abuse and cannabis misuse were each directly associated with PDI score. PDI score and psychotic features were strongly correlated. Childhood abuse did not operate through cannabis misuse to increase delusional beliefs. Including type of BD in the model did not alter the results.ConclusionEmotional and physical abuse, but also cannabis misuse, increased delusional beliefs in patients with BD. Using a quasi-dimensional measure of psychotic symptoms in BD provided higher resolution of the psychosis phenotype and helped reconcile ambiguous findings from previous studies. 相似文献

BackgroundIndividuals at clinical high risk of psychosis (CHR-P) recruited in randomized clinical trials (RCTs) and observational cohorts may display a different enrichment and hence risk of transition to psychosis. No meta-analysis has ever addressed this issue.Methods“Preferred Reporting Items for Systematic reviews and Meta-Analyses” (PRISMA) and “Meta-analysis Of Observational Studies in Epidemiology” (MOOSE)–compliant meta-analysis. PubMed and Web of Science were searched until November 2020 (PROSPERO:CRD42021229223). We included nonoverlapping longitudinal studies (RCTs-control condition and observational cohorts) reporting the transition to psychosis in CHR-P individuals. The primary effect size measure was the cumulative risk of transition at 0.5, 1, and 2 years follow-up in RCTs compared to observational cohorts. Random effects meta-analyses, heterogeneity assessment, quality assessment, and meta-regressions were conducted.ResultsNinety-four independent studies (24 RCTs, 70 observational cohorts) and 9,243 individuals (mean age = 20.1 ± 3.0 years; 43.7% females) were included. The meta-analytical risk of transitioning to psychosis from a CHR-P stage was 0.091 (95% confidence intervals [CI] = 0.068–0.121) at 0.5 years, 0.140 (95% CI = 0.101–0.191) at 1 year and 0.165 (95% CI = 0.097–0.267) at 2 years follow-up in RCTs, and 0.081 (95% CI = 0.067–0.099) at 0.5 years, 0.138 (95% CI = 0.114–0.167) at 1 year, and 0.174 (95% CI = 0.156–0.193) at 2 years follow-up in observational cohorts. There were no between-group differences in transition risks (p > 0.05). The proportion of CHR-P individuals with substance use disorders (excluding alcohol and cannabis) was higher in observational cohorts (16.8, 95% CI = 13.3–21.0%) than in RCTs (3.4, 95% CI = 0.8–12.7%; p = 0.018).ConclusionsThere is no meta-analytic evidence supporting sampling biases in RCTs of CHR-P individuals. Further RCTs are needed to detect effective interventions to prevent psychosis in this at-risk group. 相似文献

BackgroundAn elevated prevalence of Type 2 diabetes (T2D) has been observed in people with psychotic disorders and their relatives compared to the general population. It is not known whether this population also has increased genetic risk for T2D.MethodsSubjects included probands with schizophrenia, schizoaffective disorder, or psychotic bipolar I disorder, their first-degree relatives without psychotic disorders, and healthy controls, who participated in the Bipolar Schizophrenia Network for Intermediate Phenotypes study. We constructed sets of polygenic risk scores for T2D (PGRST2D) and schizophrenia (PGRSSCHIZ) using publicly available data from genome-wide association studies. We then explored the correlation of PGRST2D with psychiatric proband or relative status, and with self-reported diabetes. Caucasians and African–Americans were analyzed separately. We also evaluated correlations between PGRSSCHIZ and diabetes mellitus among Caucasian probands and their relatives.ResultsIn Caucasians, PGRST2D was correlated with self-reported diabetes mellitus within probands, but was not correlated with proband or relative status in the whole sample. In African–Americans, a PGRST2D based on selected risk alleles for T2D in this population did not correlate with proband or relative status. PGRSSCHIZ was not correlated with self-reported diabetes within Caucasian probands.ConclusionDifferences in polygenic risk for T2D do not explain the increased prevalence of diabetes mellitus observed in psychosis probands and their relatives. 相似文献

Background
Most health behavior models do not distinguish between determinants of behavior adoption and maintenance.
Purpose
This study compared psychosocial predictors of physical activity (PA) adoption and predictors of PA maintenance among 205
initially sedentary adults enrolled in a home-based PA promotion trial.
Methods
Psychosocial variables were measured at 6 months (at which point 107 participants remained inactive and 98 participants adopted
regular PA) and used to predict 12-month PA status (an indicator of PA adoption among those inactive at 6 months and an indicator
of PA maintenance among those active at 6 months).
Results
Six-month PA status moderated the relationships between 6-month measures of home access to PA equipment (p = .049), self-efficacy (p = .086), and perceived satisfaction (p = .062) and 12-month PA status. Simple effects analyses revealed that home access to PA equipment was predictive of PA adoption
(OR = 1.73; 95% CI: 1.05, 2.85), but not PA maintenance (OR = 0.88; 95% CI: 0.58, 1.35), whereas self-efficacy and perceived
satisfaction were predictive of PA maintenance (OR = 2.65; 95% CI: 1.55, 4.52; OR = 1.95; 95% CI: 0.93, 4.06), but not PA
adoption (OR = 1.50; 95% CI: 0.87, 2.57; OR = 0.82, CI: 0.44, 1.52).
Conclusion
Results suggest that these psychosocial variables may operate differently in predicting PA adoption versus maintenance. 相似文献

It is thought that hypothalamic-pituitary-adrenal (HPA) axis functioning mediates between the experience of stress and development of psychotic symptoms. This study aimed to evaluate this model in a cohort of young people at ultra high risk (UHR) of psychosis. Information about the experience of psychological symptoms and recent stressful experiences was obtained from 23 young people who met UHR criteria. Plasma samples were taken to assess cortisol and glucocorticoid receptor numbers, and an MRI scan was also performed. Plasma cortisol levels were significantly and positively correlated with the experience of 'hassles' but not with the experience of stressful life events. Significant positive associations were also found between plasma cortisol levels and level of depression and anxiety. No significant relationships were found between plasma cortisol level and global psychopathology, psychotic symptomatology, functioning or pituitary and hippocampal volumes. These results suggest that the number of hassles experienced by young people at UHR of psychosis could be an important factor in raising their cortisol levels, which might, in turn, affect the severity of depressive and anxiety symptoms. No other relationships were found between plasma cortisol levels and the experience of psychotic symptoms, functioning or hippocampal and pituitary volumes. These results indicate possible impairment in HPA-axis functioning in the early stages of psychotic illness, but further investigation of the relationships between these parameters is required. 相似文献

Summary The concept of cycloid psychosis has gained increasing acceptance during recent decades. Using the diagnostic criteria of Perris and Brockington, an intelligible delineation of a group of patients has been obtained. Few epidemiological data on cycloid psychosis have been reported so far. The objective of the present study was to describe the one-year incidence of cycloid psychosis in a clinical sample. The diagnostic registers of all patients hospitalized for a functional or an organic psychosis and discharged in the year 1983, in Lund, Sweden were investigated. 514 patients were identified of whom 83 were admitted to hospital for the first time. 29 of these patients had a functional psychosis and were below the age of 50. In this age group 7 cases (4 women, 3 men) fulfilled the diagnostic criteria of cycloid psychosis and thus constituted almost one fourth of all first admissions of functional psychoses that year. The one-year incidence for first admission in cycloid psychosis was 5.0 per 100000 inhabitants in women and 3.6 per 100000 inhabitants in men within the age group 15–50 years in the catchment area of 163 175 persons. We conclude that cycloid psychosis consitutes a considerable proportion of functional psychoses in both sexes. 相似文献

While structural abnormalities of the dorsolateral prefrontal cortex (DLPFC) may pre-date and predict psychosis onset, the relationships between functional deficits, cognitive and psychosocial impairments has yet to be explored in the at-risk period. An established measure of cognitive control (AXCPT) was administered to demographically matched clinical-high-risk (CHR; n=25), first-episode schizophrenia (FE; n=35), and healthy control (HC; n=35) participants during functional magnetic resonance imaging (fMRI) to investigate these relationships. CHR and FE individuals demonstrated impaired context processing and reduced DLPFC activation relative to HC individuals during increased cognitive control demands. FE and CHR individuals' ability to increase DLPFC activity in response to cognitive control demands was associated with better task performance. Task performance was also associated with severity of disorganization and poverty symptoms in FE participants. These findings support more extensive studies using fMRI to examine the clinical significance of prefrontal cortical functioning in the earliest stages of psychosis. 相似文献
