Background: Mobile addiction is becoming an increasingly prevalent issue among students, affecting their academic performance, social interactions, and overall health. One of the significant consequences of excessive mobile use is the negative impact on sleep quality, leading to various physical and psychological problems. Addressing these issues through educational interventions is crucial in improving students' well-being. Aim: The study aimed to assess the effectiveness of a structured teaching programme on mobile addiction patterns and sleep quality among students of Smt. Nagarathnamma College of Nursing, Bangalore. Methods: A quasi-experimental design was employed. A total of [insert number] students were selected using convenient sampling techniques. The data was collected using a standardized questionnaire that measured mobile addiction patterns and sleep quality before and after the intervention. A structured teaching programme was developed, focusing on awareness, self-regulation, and the negative consequences of mobile addiction on sleep. The programme included lectures, group discussions, and interactive activities designed to improve awareness and encourage healthy mobile usage habits. Results: Pre- and post-intervention data were analyzed using [insert statistical tools]. The results indicated a significant reduction in mobile addiction patterns and an improvement in sleep quality among the students after the structured teaching programme. The findings suggest that educational interventions can positively impact students' mobile use habits and sleep health. Conclusion: The structured teaching programme effectively reduced mobile addiction and improved sleep quality among nursing students. The study highlights the need for ongoing educational efforts to raise awareness about mobile addiction and its impact on health. Future research should focus on long-term follow-up and the impact of similar interventions in other educational settings.
