Examination of the construct validity of the Focusing Manner Scale 18(FMS-18) with exploratory and confirmatory factor analysis

Abstract

ABSTRACT Focusing practitioners and researchers emphasize the importance of Focusing attitudes. The purpose of this research was to gather evidence concerning the construct validity of the Focusing Manner Scale 18 (FMS-18) which was developed to measure Focusing attitude in daily life by conducting exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and correlation analysis. The sample comprised 319 Japanese youth. The EFA yielded a factor solution. For the CFA, five models were calculated. The final model demonstrated strong applicability to the available data. The correlation analysis revealed a moderate, significant correlation between the FMS-18 total score and the World Health Organization Quality of Life-26 scale total score on all domains.
