ABSTRACT
This study intends to validate the Indonesian translation of the original Emotion Regulation Questionnaire (ERQ) and adapt it for use with adolescents. The instrument adaptation procedure will follow the WHO's instrument adaptation recommendations. An investigation using Python Semopy programming to execute reliability and validation tests is then performed. The participants in this study were 582 high school students from Banten, Indonesia. The results demonstrate that the reliability value of the Indonesian ERQ is higher than the original ERQ. Cronbach's alpha was calculated as 0.85 for the reliability test findings, with a 95% confidence range of [CI = 0.832, 0.868]. In conclusion, the Indonesian version of the ERQ instrument demonstrates a fit model suitable for use in adolescents in Eastern cultures, including Indonesia. It is believed that this study will improve the quality of research on adolescent emotion regulation.
