The Impact of a Planned Behavior Theory-Based Digital Addiction and Screen Time Management Training on Teachers' Internet Addiction, Sleep Quality, and Psychological Well-being

This thesis focuses on problematic internet use, a widespread issue in contemporary society, and its negative effects on sleep quality and psychological well-being. The indispensable role of the internet in daily life and the risks associated with excessive use constitute an important area of research, particularly in relation to internalizing symptoms and health-related problems. Within this context, considering teachers' intensive engagement with digital media and their role as role models, the study aims to improve their awareness and behaviors regarding digital media use.

The aim of the thesis is to examine the effects of a Theory of Planned Behavior (TPB)-based Digital Addiction and Screen Time Management training program on levels of internet addiction, sleep quality, and psychological well-being among middle school teachers in Aydın province, using a randomized controlled experimental design.

In terms of methodology, a total of 102 teachers-51 in the intervention group and 51 in the control group-will be assessed before and after the training. Data will be collected using a Personal Information Form, the Young Internet Addiction Test-Short Form, the Pittsburgh Sleep Quality Index, and the Psychological Well-Being Scale.

The expected outcomes are that the implemented training will significantly reduce teachers' levels of internet addiction, improve their sleep quality, and lead to improvements in psychological well-being. These findings are expected to contribute to teachers' health and to provide guidance for the development of similar intervention programs for other populations.
