“…Finally, CD expresses a pervasively interfered autopsychic experience, which might be closer to the very phenomenality of SD than the explicit (wernickian) form of depersonalization assessed in SD score. This is also consistent with previous works [5,[7][8][9] which found qualitative experiential anomalies of cognition/ perception as specifi cally clustering in schizophrenic conditions.…”

Background: Contemporary psychopathological research has shown that some qualitative anomalies of the first-person experiential givenness qualify the subjective experience of schizophrenia. Such essential clinical features of schizophrenia have recently been condensed into 7 phenomenologically coherent clusters derived from the Bonn Scale for the Assessment of Basic Symptoms (BSABS). The experimental intent of this study was to test whether subapophanic self-centrality (i.e. a protopathic nondelusional form of intersubjective spatial disattunement) empowers the discriminant capacity of such a set of subjective experiential disturbances among different diagnostic groups. Method: Three comparably sized samples of outpatients with schizophrenia, obsessive-compulsive or mood disorders were examined with the BSABS. Logistic regression analysis was performed with diagnosis as the outcome variable. Results: Elevated scores in self-perceived cognitive disorders and abnormal self-centrality were associated with DSM-IV diagnosis of schizophrenia. Self-centrality increased the discriminant capacity of the 7 designed a priori dimensions. Conclusions: These findings confirm the previously reported aggregation of some subtle qualitative alterations of subjective experience in schizophrenia, and suggest that a careful consideration of autocentric disturbances of intersubjectivity might enrich current heuristics on schizophrenic experiential vulnerability.

Experience of Subjective Symptoms in Euthymic Patients with Bipolar Disorder

Bipolar patients often experience subjective symptoms even if they do not have active psychotic symptoms in their euthymic state. Most studies about subjective symptoms are conducted in schizophrenia, and there are few studies involving bipolar patients. We examined the nature of the subjective symptoms of bipolar patients in their euthymic state, and we also compared it to that of schizophrenia and normal control. Thirty bipolar patients, 25 patients with schizophrenia, and 21 normal control subjects were included. Subjective symptoms were assessed using the Korean version of the Frankfurter Beschwerde Fragebogen (K-FBF) and the Symptom Check List 90-R (SCL90-R). Euthymic state was confirmed by assessing objective psychopathology with the Positive and Negative Syndrome scale of Schizophrenia (PANSS), the Young Mania Rating Scale (YMRS), and the Montgomery Asberg Depression Rating Scale (MADRS). K-FBF score was significantly higher in bipolar patients than in normal controls, but similar to that in schizophrenia patients (F=5.86, p=0.004, R2=2033.6). In contrast, SCL90-R scores did not differ significantly among the three groups. Euthymic bipolar patients experience subjective symptoms that are more confined to cognitive domain. This finding supports the hypothesis that subtle cognitive impairments persists in euthymic bipolar patients.

Background:Subjective experience means subtle, not yet psychotic abnormalities of experience that might be present during remitted phase and also in prodromal phase of schizophrenia and might be accurately efficient in identifying individuals at risk of eminent psychosis (Parnas et al., 2003). Apart from schizophrenic patients, bipolar patients also experience certain subjective symptoms in their euthymic state. They often experience subtle cognitive impairment and functional disturbances during their euthymic states. These subjective experiences may be related to distorted cognitive functions in these patients. These experiences include a great variety of cognitive dysfunction complaints about attention, perception, memory, thinking, language, movement, and emotion.Objective:To measure the experience of subjective symptoms and compare them between euthymic bipolar and remitted schizophrenia patients.Materials and Methods:Thirty euthymic bipolar patients and 30 remitted schizophrenia patients as per International Classification of Diseases Tenth Revision were selected for the purpose of the study. At first, sociodemographic data were collected. And then, the patients were assessed using the scales; positive and negative syndrome scale, Young Mania Rating Scale, Hamilton Depression Rating Scale, Symptom Checklist-90-Revised, and Frankfurt Complaint Questionnaire-24.Results:Both the groups showed significant differences in terms of subjective symptoms. However, no significant correlation has been found between the objective psychopathology and subjective experience in the two groups.Conclusion:It can be suggested that the patients with schizophrenia show significantly higher subjective experience when compared with the patients of bipolar disorder.
