Long hours on mobile phones and the internet have become a source of conflict in some families. The Social and Labor Affairs Department of Nantou County Government said many child and youth protection reports are related to parent-child conflict over phone use. Some children may show dependence on digital devices, irregular routines, mood changes or different communication attitudes, increasing the risk of improper discipline.

Internet addiction is not only about time spent online, but also changes in routine, emotions, attention and family interaction. Long online use may affect sleep and learning. If parents suddenly demand children stop using devices without communication, conflict may turn into scolding, pulling or punishment. Parents can first observe daily changes, then discuss use time and situations with children.

The official website of the Public Health Bureau of Nantou County Government provides the "self-screening scale for internet use habits" to help identify children's internet use. If an eligible user scores above 11 points, it may indicate a high tendency toward internet addiction, but this cutoff does not apply to the general public. Questions can be directed to the Nantou County Community Mental Health Center at 049-2911925.

At home, parents can start with family rules, such as reducing digital device use during meals and parent-child time, setting use time with children, and increasing interaction through exercise, reading, board games or outdoor activities. When conflict occurs, emotions should be stabilized before addressing phone use. Parents can also understand children's online content and friendships, instead of relying only on one-way monitoring.
