Object relations, reality testing, and social withdrawal in schizophrenia and bipolar disorder.

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.

Object relations and reality testing in schizophrenia, bipolar disorders, and healthy controls: differences in profiles and clinical correlates.

OBJECTIVE: Deficits in object relations (OR) and reality testing (RT) functions are found in schizophrenia but have never been investigated in bipolar disorder. In the current study, we examine if there are OR and RT differences in schizophrenia and bipolar disorder compared to healthy controls and to what extent differences in clinical characteristics mediates the putative effect of diagnosis. METHODS: We used the Bell Object Relation and Reality Testing Inventory (BORRTI) to measure OR and RT in schizophrenia (n = 55), bipolar disorder (n = 51) and healthy controls (n = 158). Diagnoses and the life time presence of psychotic symptoms were evaluated based on the Structured Clinical Interview for DSM-IV. We used the Positive And Negative Symptom Scale to measure current symptoms. RESULTS: Analyses of variance with post hoc tests showed statistically significant differences in OR and RT between the Schizophrenia (SCZ), Bipolar Disorder (BD), and Healthy Control (HC) groups. Multiple regression analyses indicated that a lifetime history of psychotic symptoms contributed significantly to the variance in one BORRTI subscale (Social Incompetence) while Positive And Negative Symptom Scale components (either the positive component and emotional discomfort component) contributed significantly to the variance in all BORRTI subscales except one (Uncertainty of Perception). CONCLUSIONS: OR and RT deficits are present both in SCZ and BD, but differences appears to be mediated by differences in current positive and depressive symptoms.

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

BACKGROUND: Low 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 subject's self-esteem, and whether lowered self-esteem contributes to the development of delusions and hallucinations. METHOD: A 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). RESULTS: Premorbid 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. CONCLUSION: There 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.

Passive/apathetic social withdrawal and active social avoidance in schizophrenia: difference in underlying psychological processes.

OBJECTIVE: Social withdrawal, a core feature of negative symptoms, is differentiated into passive social withdrawal (PSW) and active social avoidance (ASA). We examined whether this differentiation was related to differences in underlying psychological processes of object relations and reality testing. METHOD: Two hundred seventy-two outpatients with schizophrenia and schizoaffective disorders from VA Connecticut Healthcare System/Connecticut Mental Health Center were evaluated using the Bell Object Relations and Reality Testing Inventory (BORRTI) and the Positive And Negative Symptoms Scale. RESULTS: Distinct patterns were found; PSW was associated with object relation subscales explaining 5% of the variance, ASA was associated with object relations and all reality testing subscales explaining 12% of the variance. CONCLUSIONS: Findings suggest differences in the underlying mechanisms behind PSW and ASA, confirming that PSW is a primary negative symptom, while ASA is related more to positive symptoms.

Neurocognitive profiles in bipolar I and bipolar II disorder: differences in pattern and magnitude of dysfunction.

OBJECTIVES: Studies on neurocognitive functioning in bipolar disorder, reporting deficits in memory, attention, and executive functioning, have primarily focused on bipolar I disorder. The aim of this study was to examine whether patients with bipolar I and bipolar II disorder have different neurocognitive profiles. METHODS: Forty-two patients with bipolar I disorder, 31 patients with bipolar II and 124 healthy controls, from a large ongoing study on psychotic disorders, were included. Neurocognitive function was measured with a comprehensive neuropsychological test battery. RESULTS: The bipolar I group performed significantly poorer than the healthy control group and the bipolar II group on all measures of memory. Compared with the control group, the bipolar I group also had significantly reduced performance on most measures of attention and executive functioning, while the bipolar II group only had a significantly reduced performance on a subset of these measures. On average, 24% of the bipolar I group had clinically significant cognitive impairment (< or =1.5 SD below the control group mean) across measures, compared with 13% of the bipolar II group. CONCLUSIONS: Patients with bipolar I and bipolar II disorder in this study have different neurocognitive profiles. Bipolar I patients have more widespread cognitive dysfunction both in pattern and magnitude, and a higher proportion has clinically significant cognitive impairments compared with patients with bipolar II. This may suggest neurobiological differences between the two bipolar subgroups.
