Each item is rated on a 5-point scale from 1 (stronglydisagree) to 5 (strongly agree). A higher score indicates a higher level of SC. According to Togari (2006), Cronbach’s alphacoefficient of the SC in his nationwide survey (n = 3000) was 0.76, the SC scale was a single factor (confirmed by exploratoryfactor analysis), and goodness of fit of the one factor model was CFI = 0.956, RMSEA = 0.056 (by confirmatory factor analysis).
