This study was aimed to investigate the relationship between smartphone addiction, loneliness, and depression in adolescents. This study was designed in a correlational-cross-sectional-descriptive model and was conducted with 1041 adolescents attending high schools in a provincial center in Eastern Turkey. The data were collected through face-to-face interviews using a personal information form, Smartphone Addiction Scale-Short Version for Adolescents, UCLA Loneliness Scale, and Kutcher Adolescent Depression Scale. The average scores for smartphone addiction were found to be higher among females, individuals with low academic success, and those with a high-income level. Similarly, the average scores for loneliness were higher among individuals residing in broken families and those with parents who have limited literacy. Additionally, the mean scores for depression were higher among individuals with low academic success and those with a high-income level. Furthermore, a significant positive correlation was observed between the duration of smartphone use and levels of smartphone addiction, loneliness, and depression. Smartphone addiction, loneliness, and depression were found to be prevalent above the moderate level in adolescents. Additionally, a significant positive correlation was observed between the depression and loneliness scores of adolescents. Pediatric and school nurses should assess children's phone use. Nurses are well-positioned to establish a follow-up program aimed at monitoring adolescents' efforts in managing smartphone use, offering continuous support, and providing guidance when necessary. The implementation of such programs enables prompt intervention in addressing any arising issues.

青少年智能手机成瘾、孤独和抑郁之间的关系：相关结构方程模型研究

这项研究旨在调查青少年智能手机成瘾、孤独感和抑郁之间的关系。这项研究采用相关横断面描述模型设计，对土耳其东部省级中心的 1041 名高中生进行了研究。这些数据是通过面对面访谈收集的，使用个人信息表、青少年智能手机成瘾量表（青少年简短版）、加州大学洛杉矶分校孤独量表和库彻青少年抑郁量表。研究发现，女性、学业成就较低的人和高收入群体的智能手机成瘾平均得分较高。同样，居住在破碎家庭和父母文化程度有限的人的孤独感平均得分更高。此外，学业成绩低的人和收入高的人的抑郁症平均得分较高。此外，智能手机使用时间与智能手机成瘾、孤独和抑郁程度之间存在显着的正相关关系。研究发现，青少年中智能手机成瘾、孤独和抑郁的普遍程度高于中等水平。此外，青少年的抑郁和孤独感得分之间存在显着的正相关关系。儿科和学校护士应评估儿童的手机使用情况。护士有能力制定后续计划，旨在监测青少年在管理智能手机使用方面的努力，提供持续支持，并在必要时提供指导。此类计划的实施可以及时干预，解决任何出现的问题。
