To investigate the association of parental and adolescents' screen time with self-rated health and to examine the mediating effects of psychosocial factors (social relationships and distress) on this association.
A cross-sectional study was conducted among 984 Brazilian adolescents (10- to 17-year-olds). Self-rated health, screen time (adolescents and parental), and perception of social relationships and distress were evaluated through self-report questionnaires. Structural equation modeling was adopted to investigate the pathways of the relationship between adolescents' screen time and self-rated health.
Adolescents' screen time was directly and negatively related to self-rated health only in boys ( r = -0.158, p = .015). In girls, screen time was related to self-rated health through distress ( r = -0.188, p = .007) and social relationships ( r = 0.176, p = .008). The models fit was adequate (χ/ df ≤ 3.0, root mean square error of approximation <0.08, comparative fit index >0.90, and Tucker-Lewis Index >0.90).
Higher screen time was associated with poor self-rated health in boys, while in girls, psychosocial factors mediated the adverse relationships between screen time and self-rated health.
探讨父母和青少年的屏幕时间与自我报告健康之间的关系，并检验心理社会因素（社会关系和困扰）在这种关系中的中介作用。
本研究采用横断面研究，对 984 名巴西青少年（10 至 17 岁）进行了调查。通过自我报告问卷评估了自我报告健康、青少年和父母的屏幕时间以及对社会关系和困扰的感知。采用结构方程模型探讨了青少年屏幕时间与自我报告健康之间关系的途径。
青少年的屏幕时间仅与男孩的自我报告健康呈直接负相关（r = -0.158，p =.015）。在女孩中，屏幕时间通过困扰（r = -0.188，p =.007）和社会关系（r = 0.176，p =.008）与自我报告健康相关。模型拟合度良好（χ/df ≤ 3.0，近似均方误差 <0.08，比较拟合指数> 0.90，塔克-刘易斯指数> 0.90）。
较高的屏幕时间与男孩的自我报告健康较差相关，而在女孩中，心理社会因素中介了屏幕时间与自我报告健康之间的不良关系。
