Validating the adult motivation for reading scale with Japanese college students

Abstract The Adult Motivation for Reading Scale (AMRS) is the only instrument available to assess adult reading motivation. This study validates the factor structures and measurement invariance of the AMRS across genders. A group of 308 Japanese college students was randomly split into two samples. The present study conducted an exploratory factor analysis (EFA) using Sample 1 to investigate the factor structures underlying the AMRS. We fitted the resulting factor model to Sample 2 utilizing a confirmatory factor analysis (CFA) and cross-validated its’ model fit. Our results of the EFA and CFA confirmed the two identified reading motivation factors (i.e., reading importance, reading efficacy and extrinsic goals for reading) in college students. In addition, we established strict measurement invariance across gender.
