The Japanese version of the Brief Core Schema Scale for schemata concerning the self and others: Identification of schema patterns and relationship with depression

Abstract

The present study investigates the reliability and validity of the Japanese version of the Brief Core Schema Scale (JBCSS), which assesses schemata concerning the self and others. We also examined the relationship between subjective depression and the schemata. Confirmatory factor analysis revealed that the JBCSS is composed of four factors: Positive-Self (PS), Negative-Self (NS), Positive-Other (PO), Negative-Other (NO). Cluster analysis identified four subgroups of these schemata. Analysis of variance found that the group with negative schema about both the self and others had the highest scores on measures of depressive symptoms. These results indicate that the JBCSS can provide more detailed information about symptoms in combination with schemata of self and others.
