many scales that can measures boredom proneness. BPS hasn't been adapted from the original language (English)
in Indonesia.
Methods. This study uses validity and reliability approach. Process of education divided into the adaptation
process and psychometric analysis process. Psychometric analysis of the BPS Indonesian Version consists of Item
Content Validity Analysis (I-CVI) & Scale Content Validity Index (S-CVI). BPS Indonesian Version was spread
twice amongst students of Medicine Program Faculty of Medicine Batch 2016─2018. Psychometric analysis of
Boredom Proneness Scale Indonesian Version as the Guttman Scale was done by counting the coefficient of
reproducibility (CR) and coefficient of scalability (CS). The adaptation process obtained BPS Indonesian Version.
Results. Based on nine experts' appraisal in experts panel, minimum I-CVI is 0,83 (minimally accepted index
0,78) on the 10th scale, and S-CVI is 0,98 (minimally accepted index 0,90). CR of BPS Indonesian Version is
0,589 (first) and 0,594 (second) which defines BPS Indonesian Version is not valid. CS of BPS Indonesian Version
is obtained as 0,177 (first) and 0,188 (second) which defines BPS Indonesian Version is not appropriate to be
used in the study.
