SAQ-INA: Safety Attitudes Questionnaire–Indonesian version; SD: standard deviation; df: degress of freedom

^aRasch model is analysed using the RUMM2030 (RUMM Laboratory Pty. Ltd., Perth, Australia)

^b Values should be close to 0 [26]

^c Values should be close to 1 [26]

^d Significant values (p<0.005) indicates overall misfit to the Rasch model

^e Values between 0.6–0.7 indicates acceptable to good internal consistency reliability [26]
