Reliability and validity of the Japanese version of the ABbreviated Impulsiveness Scale |
This study determined the reliability and validity of the Japanese version of the ABbreviated Impulsiveness Scale (JABIS). The ABIS (Coutlee et al., 2014) is a short version of the BIS-11 that is a common scale of impulsiveness. It consists of three factors: motor (4items), non-planning (4items) and attentional (5items) impulsiveness. In this research, 382 undergraduates (144male; 238female) participated. By confirmatory factor analysis, goodness-of-fit statistics supported the JABIS model (RMSEA=.060, 90%CI [.047, .072], GFI=.947, CFI=.925). We obtained high coefficient by the test-retest reliability (.908, p<.01). To check construct validity, the relationship between the JABIS and other personality measurements related to impulsiveness was examined. We obtained a positive correlation between the JABIS and the dysfunctional impulsivity, and a negative correlation between the JABIS and the reformative self-control, and also between the JABIS and the cognitive reflection. These results show the JABIS can be used as a practical measure of impulsiveness.
