The result showed that 33.8% (twenty-six respondents) had good self-control and 66.2% (fifty-one respondents) had poor self-control. Fifty-two respondents (67.5%) experienced Nomophobia, while twenty-five respondents (32.5%) did not experience Nomophobia. There was a significant correlation between self-control and Nomophobia (p = 0.023 and OR = 0.319).

INTRODUCTION Developments are related to integrated personalities, life span starting from the age of six to twelve years is called school-age. Elementary school-age children are individuals who are in a range of developmental changes, the developmental phase of school-age children is seen from several main aspects of the child’s individual personality (Murni et al., 2020). Children start to explore their capabilities during the school-age, starting from taking care of their responsibility to logical and critical thinking (Santrock, 2011).

The ideal screen time for children under the age of two years (>2 yo) is 1 hour/day, and children under the age of 18 months (<18 mo) are suggested not to be exposed to digital media directly.
