Adaptation of the Indonesian Version of the Nomophobia Scale (NMP-Q-10)

Nomophobia has become a new issue related to smartphone use. Unfortunately, in Indonesia, there is still a limited availability of valid and reliable measurement tools. This study aimed to test the construct validity of the nomophobia instrument developed by Warsah et al. (2023), which consists of 10 items adapted into Indonesian and subsequently modified by the researchers. Data were obtained from young adults, specifically university students aged 18-24 years in Yogyakarta. A total of 410 respondents participated in this study. Confirmatory factor analysis (CFA) was conducted using Jamovi. Based on the construct validity test results using unidimensional CFA, a model fit was achieved in the first stage by excluding one item (item number 10). The second stage involved using the results from the first stage and renumbering the items, which also yielded a well-fitting model with valid loading factors for all items. The results of this test indicate that the Indonesian version of the nomophobia scale is valid and reliable for use in various settings to accurately measure the level of nomophobia among university students. This data represents the findings from a study of 410 college students.
