Abstract:
OBJECTIVES: Kyung Hee-Frankfurter Beschwerde-Fragebogen(K-FBF) is a representative subjective symptom measuring tool of schizophrenic patients. We performed psychopathology measurements using K-FBF, Positive and Negative Syndrome Scale(PANSS) and Symptom Checklist-90-Revised(SCL-90-R) in patients with schizophrenia and then compared the results of these three examinations one another, in order to examine which psychopathologic aspects K-FBF might reflect and to measure the possibility whether this instrument reflect the negative symptoms or cognitive impairments, which are difficult to measure by conventional objective instruments measuring psychopathology. METHODS: All 66 patients satisfying DSM-IV criteria for schizophrenia, were approached. Their education level was more than high school and they were not in the acute stage of schizophrenia. They performed K-FBF and SCL-90-R, and at the same day, they were interviewed by one of both psychiatirsts using PANSS. We examined the patterns of K-FBF response and performed facor analysis about 10 subscales. We examined the correlation between K-FBF and age, sex and insight. Also, we performed correlation analysis among the K-FBF, PANSS and SCL-90-R. RESULTS: As for K-FBF, with increasing age, the number of positive response items and the symptom severity were decreased. Even when controlling prevalence period as control variable, the correlation remained unchanged. Performing factor analysis to the K-FBF subscales, we created 2 factors, ie summation subscales. We named those recognized distress(RD) and perceptual alteration(PA) each. Using K-FBF standardized total scores as controlling variable, we performed partial correlation between PA and PANSS negative symptom scale. The result was PA and PANSS have statistically significant correlation. This correspons with the view that Huber's basic symptoms are reflecting subjective approach of negative symptoms of schizophrenia. While K-FBF standardized total scores and PANSS total scores had statistically strong correlations, SCL-90-R total scores and PANSS total scores had statistically significant, but very mild correlations. So, we had the judgement that the correlations among the psychopathology measurement tools are more influenced by the rater than the contents of tools. CONCLUSION: We concluded that Huber's basic symptoms, measured by K-FBF, reflect more negative symptoms of schizophrenia than other symptoms. And K-FBF has more correlation with the PANSS, objective psychopathology measuring tool, than the SCL-90-R, self-report quetionnaire. But, more studies using patients with another disease stages and another demographic variables are needed in order to generalize the results of this study.
