OBJECTIVE Early detection in first-episode psychosis confers advantages for negative, cognitive, and depressive symptoms after 1, 2, and 5 years, but longitudinal effects are unknown. The authors investigated the differences in symptoms and recovery after 10 years between regional health care sectors with and without a comprehensive program for the early detection of psychosis. METHOD The authors evaluated 281 patients (early detection, N=141) 18 to 65 years old with a first episode of nonaffective psychosis between 1997 and 2001. Of these, 101 patients in the early-detection area and 73 patients in the usual-detection area were followed up at 10 years, and the authors compared their symptoms and recovery. RESULTS A significantly higher percentage of early-detection patients had recovered at the 10-year follow-up relative to usual-detection patients. This held true despite more severely ill patients dropping out of the study in the usual-detection area. Except for higher levels of excitative symptoms in the early-detection area, there were no symptom differences between the groups. Early-detection recovery rates were higher largely because of higher employment rates for patients in this group. CONCLUSIONS Early detection of first-episode psychosis appears to increase the chances of milder deficits and superior functioning. The mechanisms by which this strategy improves the long-term prognosis of psychosis remain speculative. Nevertheless, our findings over 10 years may indicate that a prognostic link exists between the timing of intervention and outcome that deserves additional study.

BACKGROUND During the last decades we have seen a new focus on early treatment of psychosis. Several reviews have shown that duration of untreated psychosis (DUP) is correlated to better outcome. However, it is still unknown whether early treatment will lead to a better long-term outcome. This study reports the effects of reducing DUP on 5-year course and outcome. METHOD During 1997-2000 a total of 281 consecutive patients aged >17 years with first episode non-affective psychosis were recruited, of which 192 participated in the 5-year follow-up. A comprehensive early detection (ED) programme with public information campaigns and low-threshold psychosis detection teams was established in one healthcare area (ED-area), but not in a comparable area (no-ED area). Both areas ran equivalent treatment programmes during the first 2 years and need-adapted treatment thereafter. RESULTS At the start of treatment, ED-patients had shorter DUP and less symptoms than no-ED-patients. There were no significant differences in treatment (psychotherapy and medication) for the 5 years. Mixed-effects modelling showed better scores for the ED group on the Positive and Negative Syndrome Scale negative, depressive and cognitive factors and for global assessment of functioning for social functioning at 5-year follow-up. The ED group also had more contacts with friends. Regression analysis did not find that these differences could be explained by confounders. CONCLUSIONS Early treatment had positive effects on clinical and functional status at 5-year follow-up in first episode psychosis.

The aims of this study were to examine the prevalence and pattern of lifetime Diagnostic and Structural Manual of Mental Disorders (fourth version) major depressive episodes, and the relationship between patient characteristics and current severity of depressive symptoms in first episode psychosis patients (FEPP). A total of 122 FEPP from the ongoing longitudinal thematically organized psychosis research study were included at first treatment. A total of 58 patients (48%) had experienced one or more major depressive episodes; 21 (17%) before onset of psychosis and 37 (30%) during or after onset of psychosis. Poor premorbid childhood adjustment, substance abuse, and excitative symptoms at start of treatment were statistically significant associated with higher current severity of depressive symptoms. Alcohol use was significantly associated with current severity of depression in men, while excitative symptoms were associated in women. Thus depressive symptoms are frequent among FEPP, with indications of gender specific differences in patient characteristics that might imply different approaches to treatment.

OBJECTIVE Transference interpretation is considered as a core active ingredient in dynamic psychotherapy. In common clinical theory, it is maintained that more mature relationships, as well as a strong therapeutic alliance, may be prerequisites for successful transference work. In this study, the interaction between quality of object relations, transference interpretation, and alliance is estimated. METHOD One hundred outpatients seeking psychotherapy for depression, anxiety, and personality disorders were randomly assigned to 1 year of weekly sessions of dynamic psychotherapy with transference interpretation or to the same type and duration of treatment, but without the use of transference interpretation. Quality of Object Relations (QOR)-lifelong pattern was evaluated before treatment (P. Høglend, 1994). The Working Alliance Inventory (A. O. Horvath & L. S. Greenberg, 1989; T. J. Tracey & A. M. Kokotovic, 1989) was rated in Session 7. The primary outcome variable was the Psychodynamic Functioning Scales (P. Høglend et al., 2000), measured at pretreatment, posttreatment, and 1 year after treatment termination. RESULTS A significant Treatment Group × Quality of Object Relations × Alliance interaction was present, indicating that alliance had a significantly different impact on effects of transference interpretation, depending on the level of QOR. The impact of transference interpretation on psychodynamic functioning was more positive within the context of a weak therapeutic alliance for patients with low quality of object relations. For patients with more mature object relations and high alliance, the authors observed a negative effect of transference work. CONCLUSION The specific effects of transference work was influenced by the interaction of object relations and alliance, but in the direct opposite direction of what is generally maintained in mainstream clinical theory.

BACKGROUND Apathy is a common symptom in first episode psychosis (FEP), and is associated with poor functioning. Prevalence and correlates of apathy 10 years after the first psychotic episode remain unexplored. OBJECTIVE The aims of the study were twofold: 1) to examine prevalence and predictors of apathy at 10 years, and 2) to examine the relationship between apathy at 10 years and concurrent symptoms, functioning and outcome, including subjective quality of life. METHODS Three-hundred-and-one patients with FEP were included at baseline, 186 participated in the 10 year follow-up. Of these, 178 patients completed the Apathy Evaluation Scale (AES-S-Apathy). Patients were classified as having apathy (AES-S-Apathy≥27) or not. The relationship between apathy and baseline variables (Demographics, Diagnosis, Duration of Untreated Psychosis), measures of symptomatology (Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia), functioning (Global Assessment of Functioning Scale, Strauss Carpenter Level of Functioning Scale) and subjective quality of life (Lehmans Quality of Life Interview) were estimated through correlation analyses and blockwise multiple hierarchical regression analysis. RESULTS Nearly 30% of patients met the threshold for being apathetic at follow-up. No baseline variables predicted apathy significantly at 10 years. Apathy was found to contribute independently to functioning and subjective quality of life, even when controlling for other significant correlates. CONCLUSIONS Apathy is a common symptom in a FEP cohort 10 years after illness debut, and its presence relates to impaired functioning and poorer subjective quality of life.

INTRODUCTION Suicidal behaviour is prevalent in psychotic disorders. Insight has been found to be associated with increased risk for suicidal behaviour, but not consistently. A possible explanation for this is that insight has different consequences for patients depending on their beliefs about psychosis. The present study investigated whether a relationship between insight, negative beliefs about psychosis and suicidality was mediated by depressive symptoms, and if negative beliefs about psychosis moderated the relationship between insight and suicidality in patients with a first episode of psychosis (FEP). METHOD One hundred ninety-four FEP-patients were assessed with a clinical interview for diagnosis, symptoms, functioning, substance use, suicidality, insight, and beliefs about psychosis. RESULTS Nearly 46% of the patients were currently suicidal. Depressive symptoms, having a schizophrenia spectrum disorder, insight, and beliefs about negative outcomes for psychosis were independently associated with current suicidality; contradicting a mediating effect of depressive symptoms. Negative beliefs about psychosis did not moderate the effect of insight on current suicidality. CONCLUSION The results indicate that more depressive symptoms, higher insight, and negative beliefs about psychosis increase the risk for suicidality in FEP-patients. The findings imply that monitoring insight should be part of assessing the suicide risk in patients with FEP, and that treating depression and counteracting negative beliefs about psychosis may possibly reduce the risk for suicidality.

TCF4 is involved in neurodevelopment, and intergenic and intronic variants in or close to the TCF4 gene have been associated with susceptibility to schizophrenia. However, the functional role of TCF4 at the level of gene expression and relationship to severity of core psychotic phenotypes are not known. TCF4 mRNA expression level in peripheral blood was determined in a large sample of patients with psychosis spectrum disorders (n=596) and healthy controls (n=385). The previously identified TCF4 risk variants (rs12966547 (G), rs9960767 (C), rs4309482 (A), rs2958182 (T) and rs17512836 (C)) were tested for association with characteristic psychosis phenotypes, including neurocognitive traits, psychotic symptoms and structural magnetic resonance imaging brain morphometric measures, using a linear regression model. Further, we explored the association of additional 59 single nucleotide polymorphisms (SNPs) covering the TCF4 gene to these phenotypes. The rs12966547 and rs4309482 risk variants were associated with poorer verbal fluency in the total sample. There were significant associations of other TCF4 SNPs with negative symptoms, verbal learning, executive functioning and age at onset in psychotic patients and brain abnormalities in total sample. The TCF4 mRNA expression level was significantly increased in psychosis patients compared with controls and positively correlated with positive- and negative-symptom levels. The increase in TCF4 mRNA expression level in psychosis patients and the association of TCF4 SNPs with core psychotic phenotypes across clinical, cognitive and brain morphological domains support that common TCF4 variants are involved in psychosis pathology, probably related to abnormal neurodevelopment.

OBJECTIVE Childhood trauma (CT) is a major risk factor for various psychiatric disorders. We wanted to determine the prevalence of CT in a catchment area-based sample of schizophrenia spectrum and affective disorder (including bipolar disorder and depressive episodes with psychotic features) and to explore potential differences in types of CT between the diagnostic groups. METHOD Three hundred five patients were recruited consecutively from psychiatric units at 3 major hospitals in Oslo, Norway, diagnosed with Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Traumatic childhood events were assessed with Childhood Trauma Questionnaire. RESULTS Eighty-two percent of the patients had experienced one or more CT events, the most frequent subtype of trauma being emotional neglect. The schizophrenia spectrum group reported significantly more physical abuse and physical neglect than the affective group. CONCLUSION A high prevalence of CT in patients with severe mental disorder was detected. This reminds us of the importance of exploring this issue when we treat such patients. The mechanisms behind these differences are unclear. Further research is needed to study potential associations between CT and the clinical picture of the disorder.

BackgroundImmigration status is a significant risk factor for psychotic disorders, and a number of studies have reported more severe positive and affective symptoms among immigrant and ethnic minority groups. We investigated if perceived discrimination was associated with the severity of these symptoms among immigrants in Norway with psychotic disorders.MethodsCross-sectional analyses of 90 immigrant patients (66% first-generation, 68% from Asia/Africa) in treatment for psychotic disorders were assessed for DSM-IV diagnoses with the Structured Clinical Interview for DSM Disorders (SCID-I, sections A-E) and for present symptom severity by The Structured Positive and Negative Syndrome Scale (SCI-PANSS). Perceived discrimination was assessed by a self-report questionnaire developed for the Immigrant Youth in Cultural Transition Study.ResultsPerceived discrimination correlated with positive psychotic (r = 0.264, p < 0.05) and depression/anxiety symptoms (r = 0.282, p < 0.01), but not negative, cognitive, or excitement symptoms. Perceived discrimination also functioned as a partial mediator for symptom severity in African immigrants. Multiple linear regression analyses controlling for possible confounders revealed that perceived discrimination explained approximately 10% of the variance in positive and depression/anxiety symptoms in the statistical model.ConclusionsAmong immigrants with psychotic disorders, visible minority status was associated with perceived discrimination and with more severe positive and depression/anxiety symptoms. These results suggest that context-specific stressful environmental factors influence specific symptom patterns and severity. This has important implications for preventive strategies and treatment of this vulnerable patient group.
