Depression and depressive symptoms 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.

Psychosocial function in schizophrenia and bipolar disorder: Relationship to neurocognition and clinical symptoms

In line with a dimensional approach to psychopathology, we examined whether psychosocial function and its relationship to neurocognition and clinical symptoms differ across schizophrenia and bipolar disorder subgroups with and without a history of affective or psychotic episodes. From the TOP study, a heterogeneous sample of individuals with schizophrenia spectrum disorders without (n = 60) and with a history of affective episodes (n = 54); individuals with bipolar spectrum disorders with (n = 64) and without a history of psychosis (n = 56) and healthy controls (n = 268) participated. Psychosocial functioning was measured with the Social Functioning Scale (self-rated) and the Global Assessment of Functioning Scale (clinician-rated), neurocognition with a comprehensive neuropsychological test battery, and symptoms with Inventory of Depressive Symptomatology, Young Mania Rating Scale, and Positive and Negative Syndrome Scale. Clinician-rated functioning was poorer in schizophrenia groups than in bipolar groups, but self-rated functioning was similar across all clinical groups and poorer than in controls. Neurocognition and current clinical symptoms were associated with psychosocial function in bivariate analyses, but current symptoms had a greater independent contribution to functioning than neurocognition across clinical groups in multivariate analyses. Despite differences in neurocognition and psychosocial function, groups showed the same pattern in prediction of functioning irrespective of DSM-IV or clinical definition.

Suicidality in first episode psychosis is associated with insight and negative beliefs about psychosis

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.

Perceived discrimination is associated with severity of positive and depression/anxiety symptoms in immigrants with psychosis: a cross-sectional study

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.

Self-esteem is associated with premorbid adjustment and positive psychotic symptoms in early psychosis

BackgroundLow levels of self-esteem have been implicated as both a cause and a consequence of severe mental disorders. The main aims of the study were to examine whether premorbid adjustment has an impact on the subjects self-esteem, and whether lowered self-esteem contributes to the development of delusions and hallucinations.MethodA total of 113 patients from the Thematically Organized Psychosis research study (TOP) were included at first treatment. The Positive and Negative Syndrome Scale (PANSS) was used to assess present symptoms. Premorbid adjustment was measured with the Premorbid Adjustment Scale (PAS) and self-esteem by the Rosenberg Self-Esteem Scale (RSES).ResultsPremorbid social adjustment was significantly related to lower self-esteem and explained a significant proportion of the variance in self-esteem. Self-esteem was significantly associated with the levels of persecutory delusions and hallucinations experienced by the patient and explained a significant proportion of the variance even after adjusting for premorbid functioning and depression.ConclusionThere are reasons to suspect that premorbid functioning is an important aspect in the development of self- esteem, and, furthermore, that self-esteem is associated with the development of delusions and hallucinations.

Assessment of social anxiety in first episode psychosis using the Liebowitz Social Anxiety scale as a self-report measure.

OBJECTIVE Social anxiety is a common problem in psychotic disorders. The Liebowitz Social Anxiety Scale, Self-Rating version (LSAS-SR) is a widely used instrument to capture different aspects of social anxiety, but its psychometric properties have not been tested in this patient group. The aims of the present study were to evaluate the psychometric properties of the LSAS-SR in patients with first episode psychosis, to investigate whether it differentiated between active and passive social withdrawal and to test which clinical factors contributed to current level of social anxiety. METHOD A total of 144 first episode psychosis patients from the ongoing Thematically Organized Psychosis (TOP) study were included at the time of first treatment. Diagnoses were set according to the Structured Clinical Interview (SCID-1) for DSM-IV. A factor analysis was carried out and the relationship of social anxiety to psychotic and general symptomatology measured by the Positive and Negative Syndrome Scale (PANSS) was evaluated. Possible contributors to social anxiety were analyzed using multiple hierarchic regression analysis. RESULTS The factor analysis identified three subscales: public performance, social interaction and observation. All three subscales showed satisfactory psychometric properties, acceptable convergent and discriminate properties, and confirmed previous findings in social anxiety samples. Self-esteem explained a significant amount of the variance in social anxiety, even after adjusting for the effects of delusions, suspiciousness and depression. CONCLUSION The study shows that the LSAS-SR can be used in this patient group, that social anxiety is strongly related to both behavioral social avoidance and to self-esteem. The results support the use of this measure in assessment of social anxiety in both clinical settings and in research.

Social dysfunction in first-episode psychosis and relations to neurocognition, duration of untreated psychosis and clinical symptoms

Signs of social dysfunction are present early in the course of psychotic disorders. There is a lack of knowledge about how premorbid function, illness history, psychotic symptoms and neurocognitive characteristics are related to social function in patients with first episode psychosis (FEP). The relationship between these factors could provide important information about the psychopathology underlying social dysfunction and have implications for future prevention and treatment efforts. Our objective is to identify early predictors of social functioning in patients with FEP. We examined 166 patients and 166 age- and gender-matched healthy controls (HC). We used a validated and comprehensive measure of social functioning (the Social Functioning Scale), a comprehensive neurocognitive test battery, in addition to measures of psychotic symptoms, duration of untreated psychosis (DUP) and premorbid adjustment (the Premorbid Adjustment Scale). Lower childhood level of social adjustment and lower psychomotor speed had the strongest influence across measures of social functioning while symptoms and DUP had a weaker influence. The main result of the current study is that premorbid social adjustment and psychomotor speed had the strongest association with measures of social functioning in patients with FEP.

Subjective quality of life in first-episode psychosis. A ten year follow-up study

UNLABELLED Subjective quality of life (S-QoL) is an important outcome measure in first episode psychosis (FEP). The aims of this study were to describe S-QoL-development the first 10-years in FEP patients and to identify predictors of this development. METHODS A representative sample of 272 patients with a first episode psychotic disorder was included from 1997 through 2000. At 10 year follow-up 186 patients participated. QoL was measured by the Lehmans Quality of Life Interview. Linear mixed model analyses were performed to investigate longitudinal effects of baseline psychiatric symptoms and socio-economic variables and the effects of changes in the same variables on S-QoL-development. RESULTS S-QoL improved significantly over the follow-up period. More contact with family and a better financial situation at baseline had a positive and longstanding effect on S-QoL-development, but changes in these variables were not associated with S-QoL-development. Higher depressive symptoms and less daily activities at baseline both had a negative independent effect, but a positive interaction effect with time on S-QoL-development indicating that the independent negative effect diminished over time. In the change analysis, increased daily activities and a decrease in depressive symptoms were associated with a positive S-QoL-development. CONCLUSIONS Treatment of depressive symptoms and measures aimed at increasing daily activities seem important to improve S-QoL in patients with psychosis. More contact with family and a better financial situation at baseline have a long-standing effect on S-QoL-development in FEP patients.

Low vitamin D is associated with negative and depressive symptoms in psychotic disorders

BACKGROUND There are indications that low S-25(OH)D is associated with increased disease severity in psychotic disorder. Our first aim was to investigate the relations between low S-25(OH)D and positive, negative and depressive symptoms. Our second aim was to explore if associations between S-25(OH)D and symptoms were influenced by levels of inflammatory markers. METHODS Participants (N=358) with a medical history of one or more psychotic episodes were recruited. Current symptomatology was assessed by The Structured Interview for the Positive and Negative Syndrome Scaleanalyzed by a five-factor model. The Calgary Depression Scale for Schizophrenia was used to assess depression and suicidal ideation. Blood samples were analyzed for S-25(OH)D, CRP, sTNF-R1, IL-Ra and OPG. We performed bivariate correlations and multiple regression models to evaluate the effect of S-25(OH)D on the outcomes. RESULTS Low S-25(OH)D was significantly associated with negative symptoms (adjusted R2=0.113, F(6,357)=8.58, p<0.001) and with depression (adjusted R2=0.045, F(4,357)=5.233, p<0.001) when adjusting for possible confounding factors (i.e. gender, education, diagnose, hospitalization status, ethnicity, season and thyroid status). CRP was correlated with both S-25(OH)D (rho=-0.13, p=0.02) and negative symptoms (rho=0.14, p=0.01), but did not act as a mediator. The correlations between S-25(OH)D and the inflammatory markers sTNF-R1, IL-Ra and OPG were not significant. CONCLUSION There is a strong association between low S-25(OH)D and higher negative and depressive symptoms in psychotic disorders. Randomized controlled trials should be performed to investigate the effect of vitamin D supplementation as adjuvant treatment strategy in patients with prominent negative or depressive symptoms.

Object Relations, Reality Testing, and Social Withdrawal in Schizophrenia and Bipolar Disorder

Abstract In this study, we investigated the relationships between observed social withdrawal (Positive and Negative Syndrome Scale [PANSS] Passive Social Withdrawal and PANSS Active Social Avoidance), subjectively experienced social withdrawal (Social Functioning Scale [SFS] Withdrawal and SFS Interpersonal Behavior), and their associations to the underlying psychological patterns of Object Relations and Reality Testing. Patients with schizophrenia (n = 55) and bipolar disorder (n = 51) from the ongoing Thematically Organized Psychosis project, Oslo University Hospital, Norway, were evaluated using the Bell Object Relations and Reality Testing Inventory, the PANSS, and the SFS. Object relations and reality testing subscales related differentially to PANSS Passive Social Withdrawal and PANSS Active Social Avoidance. These two measures, together with the level of alienation, explained a significant amount of variance in self-experienced social dysfunction. Findings reveal the multidimensional nature of social dysfunction in severe mental disorders.
