The pervasiveness of prolonged screen viewing (SV) in adolescence is of significant concern given its well-documented implications with various health outcomes. Based on Social Cognitive Theory (SCT), this study explored how a wide range of individual, environmental, and behavioral factors correlate with adolescents’ SV duration. The study used adolescents’ self-reported data from the cross-sectional Family Life, Activity, Sun, Health and Eating (FLASHE) study implemented by the National Cancer Institute (NCI). Findings indicated that adolescents’ SV duration were different across various age and ethnic groups. It was positively associated with emotion regulation and negatively connected with self-efficacy in limiting screen time. Compared to un-authoritative parenting style, authoritative parenting had an advantage in curbing adolescents’ screen use. General media susceptibility strongly correlated with SV duration. Perception of peers’ behaviors (descriptive norm) and how peers would react adversely (injunctive norm) were both connected with SV duration. SV duration was negatively connected with physical activity whereas positively linked with sedentary behavior. Theoretical and practical implications were outlined, as well as limitations and directions for future research.

鉴于其对各种健康结果的有据可查的影响，青春期长时间观看屏幕 (SV) 的普遍性引起了人们极大的关注。本研究基于社会认知理论 (SCT)，探讨了广泛的个人、环境和行为因素如何与青少年的 SV 持续时间相关。该研究使用了青少年自我报告的数据，这些数据来自美国国家癌症研究所 (NCI) 实施的家庭生活、活动、阳光、健康和饮食 (FLASHE) 横断面研究。研究结果表明，青少年的 SV 持续时间在不同年龄和种族群体中是不同的。它与情绪调节呈正相关，与限制屏幕时间的自我效能感呈负相关。与非权威的育儿方式相比，权威的养育方式在抑制青少年使用屏幕方面具有优势。一般介质易感性与 SV 持续时间密切相关。对同伴行为的感知（描述性规范）以及同伴如何做出不利反应（禁令规范）都与 SV 持续时间有关。SV 持续时间与体力活动呈负相关，而与久坐行为呈正相关。概述了理论和实践意义，以及未来研究的局限性和方向。
