[Reliability and validity of the Japanese version of the Brief Core Schema Scales].
The Brief Core Schema Scales (BCSS; Fowler, Freeman, Smith, kuipers, Bashforth, Coker, Hodgekins, Gracie, Dunn, and Garety, 2006) were devised to assess schemata concerning the self and others. In the BCSS, four schemata--Negative Self (NS), Positive Self (PS), Negative Others (NO), and Positive Others (PO)--are assessed by means of self-ratings. In this study, we developed the Japanese version of the BCSS (JBCSS) and reported the reliability and validity of the scales, using Japanese undergraduates. There were 200 students in the first survey (Time 1) and 128 in the second survey (Time 2). The results revealed that the JBCSS had a four-factor structure, good internal consistency, and acceptable test-retest reliability. In addition, multiple regression analyses with schemata as the independent variables and paranoid ideation and grandiose ideation as the dependent variables indicated that negative schemata about the self and others were generally associated with paranoid ideation, and positive schemata about the self were associated with grandiose ideation. The analyses suggested that the JBCSS had good reliability and validity as a measure of schemata about the self and others related to paranoid and grandiose ideation.
