Project Summary A concomitant rise in adolescent social media use and decline in adolescent mental health over the last decade has raised the question as to the degree of relationship between these factors. To better understand this relationship, we examine how passive social media use (pSMU)—monitoring other people’s lives without engaging in direct exchanges with others—leads to poor mental health (Aim 1), when people engage in pSMU and how this coping strategy impacts mental health (Aim 2), and for whom pSMU is likely to undermine mental health (Aims 3) in a longitudinal study (n=400) in adolescents (ages 13-17; 50% Male/Female; 50% Black/White youth). There will be a 2-month focused study period. The initial and final 2 weeks of the 2-month study period will use ecological momentary assessment-based surveys (5 prompts a day) to measure pSMU, and to characterize affective responses to both pSMU and stress exposures the youth encounter in daily life. Objective pSMU will also be measured using an app installed on the youth’s phone in order to continuously measure pSMU over the entire 2-month intensive study period. We will measure stress exposures and responses in two novel ways. First, using GPS tracking we will determine the youth’s exposures to objectively stressful environments (i.e., high crime areas). Second, we will use GPS to trigger EMA prompts at locations youth reported as being stressful at baseline. The influences of these experiences on mental health trajectories (measured at weeks 0,2,4,6,8 and 20 will be assessed. Additionally, we focus on the relationship of pSMU to two physiological pathways that are responsive to social stress and influence risk for poor mental health: a) the parasympathetic nervous system, the function of which will be continuously measured using a self-charging wristband worn by the youth for the entire 2-month intensive study period to quantify shifts in heart-rate variability (HRV); b) and the expression of immune and other socially stress responsive gene pathways in blood cells sampled on week 0,2,6, and 8. This will provide the opportunity to determine the effects of pSMU on momentary affect, momentary HRV, immune related gene expression, a marker of general inflammation (CRP), and changes in depressive symptoms (Aim 1). We will also determine the role of stressor exposure (self-reported and GPS based) upon pSMU (Aim 2a) and the degree to which pSMU as a stress coping strategy moderates the effects of stressor exposure on affective response, HRV, stress related gene signaling pathways, inflammation, and mental health measures (Aim 2b). To examine individual differences in these effects, we will determine the degree to which gender is associated with increased pSMU (Aim 3a) and whether gender moderates responses to pSMU (Aim 3b). Finally, because our sample will be half Black youth, we will also determine if race moderates the relationship between GPS derived stress exposures (including GPS determined exposure to heavily policed areas or racially exclusive areas) and pSMU (Aim 3c).

项目摘要 伴随而来的是青少年社交媒体使用率的上升和青少年心理健康水平的下降 十年提出了关于这些因素之间的关系程度的问题。为了更好地理解 在这种关系中，我们考察了被动社交媒体的使用(PSMU)--在没有 与他人进行直接交流--当人们参与PSMU时，会导致较差的心理健康(目标1 以及这种应对策略如何影响心理健康(目标2)，以及对谁来说，PSMU可能会破坏心理 健康(目标3)在青少年(13-17岁；男女各占50%；男女各占50%)的纵向研究中(n=400) 黑人/白人青年)。将有2个月的集中学习时间。2个月的头两周和最后两周 研究期间将使用基于生态瞬时评估的调查(每天5次提示)来测量PSMU， 并对青年在日常生活中遇到的PSMU和压力暴露的情感反应进行表征。 目标PSMU也将使用安装在青少年手机上的应用程序进行测量，以便连续 在整个2个月的强化学习期间测量PSMU。我们将测量压力暴露和 以两种新颖的方式做出回应。首先，使用GPS跟踪，我们将客观地确定青少年暴露在 压力大的环境(即犯罪率高的地区)。其次，我们将使用GPS在地点触发EMA提示 据报道，年轻人在基线时压力很大。这些经历对心理健康轨迹的影响 (在第0、2、4、6、8和20周进行评估。此外，我们还重点研究了PSMU与 对社会压力作出反应并影响心理健康不良风险的两条生理途径：a) 副交感神经系统，其功能将使用自我充电进行连续测量 年轻人在整个为期两个月的强化学习期间佩戴的腕带，以量化心率的变化 变异性(HRV)；b)以及免疫和其他社会应激反应基因途径的表达 在第0、2、6和8周采集血细胞。这将提供机会来确定PSMU的效果 短暂性情感、短暂性心率变异性、免疫相关基因表达、全身炎症标志物 (CRP)和抑郁症状的变化(目标1)。我们还将确定应激源暴露的作用 (自我报告和基于全球定位系统)基于PSMU(目标2a)和PSMU作为压力应对的程度 策略缓和应激源暴露对情感反应、心率变异性、应激相关基因信号的影响 途径、炎症和心理健康措施(目标2b)。为了考察这些方面的个体差异 ，我们将确定性别与PSMU增加的关联程度(目标3a)和 性别是否影响对PSMU的反应(目标3b)。最后，因为我们的样本将有一半是黑人青年， 我们还将确定种族是否缓和了GPS衍生的压力暴露之间的关系(包括 全球定位系统确定了在戒备森严的地区或种族隔离地区的接触情况)和PSMU(目标3c)。
