Formal Thought Disorder and Self-Disorder: An Empirical Study.

Background: Formal thought disorder was constitutively linked to the original concept of schizophrenia and has since been one of central features supporting its diagnosis. Bleuler considered formal thought disorder as a fundamental symptom of schizophrenia among other fundamental symptoms, including ego disorders. The contemporary concept of self-disorder represents a more developed, nuanced, and systematic approach to disturbances of self-experience than the Bleulerian concept of ego disorders. As fundamental symptoms, on Bleuler's account, are persistently present in every case, an association between these symptoms could be expected. The purpose of this study was to examine the association between self-disorder and formal thought disorder. Methods: A sample of 94 diagnostically heterogeneous patients was examined for formal thought disorder using clinical rating and a proverb test. The proverb test was analyzed for two different aspects of formal thought disorder: literal responses and bizarre responses. The sample was comprehensively assessed for psychopathology, including self-disorder as measured with the Examination of Anomalous Self-Experience scale. Results: The patients, who provided bizarre responses, had a higher level of self-disorder, more negative symptoms, lower level of social functioning, and lower level of intelligence. Bizarre answers aggregated in patients diagnosed within the schizophrenia spectrum compared with patients outside the schizophrenia spectrum. We found moderate correlations between the two measures of formal thought disorder (clinically rated and bizarre responses) and self-disorder (0.454 [p < 0.01] and 0.328 [p < 0.01]). Literal responses did not differ between diagnostic groups and also did not correlate with bizarre responses. Specificity of bizarre responses for a diagnosis within schizophrenia spectrum was 86.89%, whereas sensitivity was 40.85%. Conclusion: The close relation between formal thought disorder and self-disorder further adds to the notion of self-disorder as a unifying psychopathological core beneath the apparently heterogeneous symptoms of schizophrenia.

The Paradox of Help-Seeking Behaviour in Psychosis.

Little is known about which factors actually motivate individuals with psychosis to seek help or how psychosis may complicate the help-seeking process. The aim of this article is to examine the steps of this process and how psychopathological experiences might affect and interfere with it. In this qualitative study we interviewed nine patients with a first episode of psychosis. The interviews were transcribed and analysed according to the principles of thematic analysis using inductive as well as deductive methods. The crucial step in help-seeking behaviour seemed to be for the patients to identify the kind of problem they were facing. None of them clearly recognized their psychotic or otherwise anomalous experiences as symptoms of a mental disorder, and most of them did not seriously question the reality status of these experiences. For most of the patients it was an untenable social situation that caused them to seek help. When they did seek help the majority did not initially contact the psychiatric services. It seems paradoxical to expect patients who experience symptoms of psychosis for the first time to be able to unambiguously identify them as being exactly that and accordingly seek out psychiatric help, as diminished insight into illness is an inherent feature of psychosis. However, the phenomenon of 'double bookkeeping' seemed to provide an opening for seeking help from psychiatry in spite of compromised insight. This observation should be included in everyday clinical work and in future information campaigns.

Measuring Psychotic-Like Experiences in the General Population.

INTRODUCTION: The notion of a full psychosis continuum in which psychosis is seen on a continuum with normal experience rests heavily on studies showing that psychotic symptoms are common in the general population. However, the methods of assessment in the studies have been criticized. OBJECTIVES: (1) to investigate how many from the general population who answered positively on a psychotic-like symptoms questionnaire and (2) to clinically assess a subset of those with psychotic-like experiences (PLE). METHODS: A self-rating questionnaire concerning PLEs was given to individuals from the general population. A subsample of those, who scored positively for PLEs, was clinically assessed for psychosis. RESULTS: Totally, 5.7% of the participants rated positive for PLEs according to the self-rating questionnaire. Forty of these were clinically assessed and 7 (17.5%) of them were found to have had a psychotic experience, 4 of them were already in psychiatric treatment. CONCLUSION: The self-reported psychotic-like phenomena were more common in the general population than psychotic disorders. However, when assessed clinically, the experienced phenomena did correspond to psychotic phenomena except in a few patients, who were found to suffer from a psychotic disorder. Overall, we did not find support for the full psychosis continuum model.

Caregiver distress in first-episode psychosis: the role of subjective appraisal, over-involvement and symptomatology.

BACKGROUND: Caregivers of persons with first-episode psychosis (FEP) often report high levels of distress. Preventing long-term or chronic distress within the whole family is an important focus of early intervention for psychosis. However, a more comprehensive understanding of the psychological factors involved is needed. AIMS: To examine the impact of subjective appraisals and expressed emotion on caregiver distress in FEP. METHOD: Within a cross-sectional design, 154 caregivers of 99 persons with FEP in a clinical epidemiological sample completed a series of questionnaires to examine potential predictors of caregiver distress. RESULTS: Thirty-seven percent of caregivers were suffering from clinically significant distress. A linear mixed model analysis found that, after controlling for caregiver socio-demographic factors, service-user symptoms and global functioning, emotional over-involvement and subjective appraisal of caregiving were significant predictors of caregiver distress. CONCLUSION: Caregiver distress is significant in the early phase of illness, and this seems to be more related to their subjective appraisal and over-involvement, than to variations in symptoms and global functioning of the person diagnosed with FEP. This lends further support to the stress-appraisal coping model and the cognitive model of caregiving in FEP, and highlights supportive interventions aimed at handling unhelpful cognitions and behaviors.
