目的迄今为止，人们对媒体内容和总体屏幕时间对青少年心理功能影响的潜在心理生理学贡献知之甚少。在本研究中，我们将呼吸性窦性心律失常（RSA）作为特定类型的媒体内容使用、总体媒体暴露以及青少年内化和攻击性症状的发展之间联系的调节因素。方法以 374 名青少年（平均年龄 = 15）为样本，报告了他们在第 1 时间（2011 年）和 1 年随访（2012 年）时的媒体使用、内化行为和攻击性行为。 RSA 反应性是在一项具有挑战性的实验室任务中收集的。进行路径分析来测试假设的媒体使用、媒体内容和 RSA 反应性之间的三向交互模型，分别针对内化和攻击性问题。结果发现攻击性媒体内容存在显着的交互作用，但亲社会媒体内容则不然。对于攻击性内容，表现出 RSA 戒断的青少年在接触更多的屏幕时间和攻击性内容时报告了明显更严重的内化和攻击性症状。结论这些研究结果表明，RSA 戒断加剧的情况可能会使青少年面临更大的暴力媒体负面影响的风险，而亲社会媒体内容可能不会显着影响青少年的精神病理学发展。讨论了心理生理学对我们理解媒体效果的影响。
PurposeTo date, little is known about underlying psychophysiological contributions to the impact of media content and overall screen time on adolescent psychological functioning. In the present study we examine respiratory sinus arrhythmia (RSA) as a moderator of the link between specific types of media content use, overall media exposure, and the development of internalizing and aggressive symptoms in youth.MethodsA sample of 374 adolescents (mean age = 15) reported on their media use, internalizing behavior, and aggressive behavior at time 1 (2011) and 1-year follow-up (2012). RSA reactivity was gathered during a challenging laboratory task. Path analyses were conducted to test the hypothesized three-way interaction model between media use, media content, and RSA reactivity, separately for internalizing and aggressive problems.ResultsSignificant interactions were found for aggressive, but not prosocial, media content. For aggressive content, youth exhibiting RSA withdrawal reported significantly greater internalizing and aggressive symptoms when exposed to higher amounts of screen time and aggressive content.ConclusionsThese findings suggest that profiles of heightened RSA withdrawal may place adolescents at greater risk to the negative impact of violent media, whereas prosocial media content may not significantly impact youth development of psychopathology. Implications for the role of psychophysiology in our understanding of media effects are discussed.
