AbstractObjectives Cognitive models suggest that beliefs and appraisal processes are crucially important in the onset and persistence of psychosis. This study investigated whether (i) neuroticism increases the risk for development of psychotic symptoms, and (ii) a delusional interpretation and/or a depressed response to hallucinatory experiences predicts the onset of psychotic disorder.Method A general population sample with no lifetime evidence of any psychotic disorder was interviewed with the Composite International Diagnostic Interview Schedule (CIDI) at baseline and 1 and 3 years later. At year 3, individuals with CIDI evidence of psychotic symptoms were interviewed by clinicians to identify onset of psychotic disorder.Results Baseline level of neuroticism increases the risk for incident psychotic symptoms. Given the presence of hallucinatory experiences at baseline, the increase in risk of having the psychosis outcome was much higher in the group with delusional ideation or depressed mood at year 1 than in those without delusional ideation or depressed mood.Conclusion A cognitive style characterised by a tendency to worry increases the risk for newly developed psychotic symptoms. Individuals who report hallucinatory experiences and react to these with a delusional interpretation and/or negative emotional states have an increased risk for developing clinical psychosis. 相似文献

Objective:
To examine the hypothesis that the “natural” combination of delusions and hallucinations in psychotic disorders in fact represents a selection of early subclinical hallucinatory experiences associated with delusional ideation, resulting in need for care and mental health service use.Methods:
In the Early Developmental Stages of Psychopathology study, a prospective, 10-year follow-up of a representative cohort of adolescents and young adults in Munich, Germany (n = 2524), clinical psychologists assessed hallucinations and delusions at 2 time points (T2 and T3). Analyses compared differences in psychopathology, familial liability for nonpsychotic disorder, nongenetic risk factors, persistence, and clinical outcome between groups characterized by: (1) absence of positive psychotic symptoms, (2) presence of isolated hallucinations, (3) isolated delusions, and (4) both hallucinations and delusions.Results:
Delusions and hallucinations occurred together much more often (T2: 3.1%; T3: 2.0%) than predicted by chance (T2: 1.0%; T3: 0.4%; OR = 11.0; 95% CI: 8.1, 15.1). Content of delusions was contingent on presence of hallucinations but modality of hallucinations was not contingent on presence of delusions. The group with both hallucinations and delusions, compared to groups with either delusions or hallucinations in isolation, displayed the strongest associations with familial affective liability and nongenetic risk factors, as well as with persistence of psychotic symptoms, comorbidity with negative symptoms, affective psychopathology, and clinical need.Conclusions:
The early stages of psychosis may involve hallucinatory experiences that, if complicated by delusional ideation under the influence of environmental risks and (liability for) affective dysregulation, give rise to a poor prognosis hallucinatory–delusional syndrome. 相似文献3.

Background: Psychotic major depression (PMD) is a severe mental disorder characterized by high levels of illness severity, chronicity, impairment, and treatment resistance. However, most past research on PMD has been conducted in inpatient hospital samples, and relatively little is known about PMD patients presenting for treatment in the community specifically. Methods: In this study, we examined the prevalence and clinical characteristics of PMD in a large sample (n=2,500) of treatment‐seeking outpatients who were administered structured clinical interviews by trained diagnosticians. Results: Of the patients diagnosed with major depression, 5.3% had psychotic features. PMD patients were more likely to be members of a racial/ethnic minority and to have lower educational attainment compared to those with nonpsychotic major depression. In addition, PMD patients were found to have greater current depression severity, suicidal ideation, and social and work impairment. These patients also were more likely to have histories of suicide attempts and psychiatric hospitalizations, to report an earlier age of illness onset, and to meet criteria for chronic depression. In terms of psychiatric comorbidity, PMD patients had higher rates of certain anxiety disorders as well as more somatoform and cluster A personality disorders. Conclusions: Results indicated that PMD was present in a relatively small percentage of treatment‐seeking outpatients but was associated with disproportionately high levels of severity and impairment. Similarities and differences between the current findings and those from past research are discussed, including clinical implications for the identification and treatment of PMD in routine practice settings.

BackgroundSelf-reflectiveness, one dimension of cognitive insight, plays a protective role in an individual’s mental state. Both high and low levels of self-reflectiveness have been reported in patients with schizophrenia and individuals at clinical high risk for the illness.AimsThis study aimed to explore the relationship patterns between self-reflectiveness and clinical symptoms in individuals during the pre-morbid and early clinical stages of psychosis.MethodsA total of 181 subjects, including individuals with attenuated positive symptoms (APS, n=122) and patients with first-episode psychosis (FEP, n=59), completed the Beck Cognitive Insight Scale and were evaluated using the Schedule of Assessment of Insight and Positive and Negative Syndrome Scale. All subjects were classified into three groups according to their level of self-reflectiveness: low level (LSR, n=59), medium level (MSR, n=67) and high level (HSR, n=55). Both linear and non-linear relationships between self-reflectiveness and clinical symptoms were explored.ResultsMore individuals with APS were classified into the MSR group, while more patients with FEP were classified into the LSR group. The LSR group demonstrated less awareness of illness than the MSR and HSR groups, more stereotyped thinking and poorer impulse control but less anxiety than the MSR group, and lower levels of blunted affect and guilt feelings than the HSR group. The MSR group demonstrated lower stereotyped thinking than the HSR group. Compared to the LSR group, the MSR group had increased self-reflectiveness, improved awareness of illness, decreased stereotyped thinking, and better impulse control, but increased feelings of guilt. The HSR group showed increased stereotyped thinking when compared to the MSR group, but the other variables did not change significantly between these two groups. Overall, self-reflectiveness demonstrated an approximately inverse S-shaped relationship with the awareness of illness, a U-shaped relationship with stereotyped thinking and poor impulse control, and an almost linear relationship with anxiety and guilt feelings.ConclusionsSelf-reflectiveness demonstrates complex relationships with clinical symptoms and fails to exert significant positive effects when reaching a certain high level. 相似文献

BACKGROUND: Psychotic (delusional) major depression (PMD) in the elderly is a common condition in inpatient settings. There is evidence that late age onset depressives are more likely to be psychotic. OBJECTIVES: The aim of this study was to investigate the frequency, sociodemographic, and clinical characteristics of PMD in hospitalized elderly depressives. METHODS: The sample consisted of 118 elderly patients consecutively admitted at three different clinics. All patients fulfilled DSM-IV criteria for major depression disorder and were diagnosed on the basis of Structured Clinical Interview for DSM-IV (SCID). The subjects were also assessed using the Hamilton Rating Scale for Depression, the Mini Mental State Examination (MMSE) and a physical health rating scale. RESULTS: PMD was positively associated with age of depression onset over 60 [corrected]. The PMD patients were also more severely depressed, more psychomotorically retarded and referred more past psychotic depressive episodes. Furthermore, age at onset influenced the type of delusions, so that PMD patients with age [corrected] over 60 at onset expressed delusions of hypochondriacal and nihilistic content more frequently. CONCLUSIONS: The results of our study demonstrated that PMD in the elderly has a later age at onset. 相似文献

Aim: The aim is to examine disengagement in an early psychosis treatment service and contrast clinical and demographic variables of patients who disengage against those who do not. Methods: Those with termination of treatment, despite therapeutic need within 12 months of entry (disengagers) (n = 57; 24.6%), were compared with those who remained in treatment at 12 months (n = 175) on a range of clinical and demographic variables collected at admission. After testing the difference between proportions, data analysis was conducted using methods of logistic regression. Results: Alcohol and/or cannabis abuse/dependence, initial diagnosisother than mood disorder, long duration of untreated psychosis, lower Positive and Negative Syndrome Scale total symptoms, and lower insight at referral accounted for 27% of variance in patient ‘disengagement’ within 12 months. Conclusion: A significant proportion of patients with first episode psychosis disengage from treatment within 12 months. Despite a number of factors being associated with disengagement, prediction using admission factors was poor. Early Intervention in Psychosis Services would benefit from increased attention to alcohol and drug problems, trying to reduce the duration of untreated psychosis, improving psychiatric symptoms and increasing insight in all patients to decrease service disengagement. 相似文献

Objective: The aim was to elucidate the relationship between psychotic and behavioural symptoms in the elderly. Method: A representative sample of 85 year old subjects living in Gothenburg, Sweden (n = 451) was assessed with neuropsychiatric examinations, key informant interviews and record reviews. Results: Fourteen percent of these very elderly subjects had paranoid symptoms with concomitant anxious agitation and/or irritability/anger. Hallucinations and paranoid symptoms were both associated with a pattern of behavioural symptoms including both anxious agitation and irritability/anger simultaneously in both demented [hallucinations, Odds ratio (OR) 2.8, Confidence interval (CI) 1.2–6.7, paranoid symptoms OR 5.6 CI 2.2–14.2] and non‐demented ( hallucinations OR 3.2 CI 1.2–8.3, paranoid symptoms OR 4.8 CI 2.0–11.8). Conclusion: Psychotic symptoms are associated with behavioural symptoms regardless of dementia status. Since these symptoms lead to decreased ability to function in daily life and increased caregiver burden, it is important for health professionals to identify and treat these symptoms also in non‐demented. 相似文献
