Social support can mitigate the severity of posttraumatic stress disorder (PTSD) in children and adults following traumatic events. However, little is known about the role of social support in high-risk samples of adolescents from the community. The present study examined the relationship between social support and PTSD symptoms in adolescents exposed to traumatic events and childhood adversity, after adjusting for the effects of potential covariates, including sociodemographic factors, previous childhood adversity, level of exposure, comorbid anxiety, depression symptoms, and substance abuse, and coping strategies.
The participants of the study were 183 adolescents, mean age of 16 years old (M=15.71, SD=1.31), ranged between 13 and 17 years old, 89 (48.6%) males and 94 (51.4%) females.
The results revealed that 26.2% of the sample met the criteria for probable PTSD. Our statistical model explained 64% of the variance in PTSD symptoms, but social support was not significant after adjusting for covariates. This study found that social support was not enough to reduce PTSD symptoms in adolescents exposed to trauma and adversity. Programs focused only on improving social support may not be effective in reducing mental health symptoms for adolescents, particularly when there has been severe and/or multiple forms of childhood adversity.
社会支持可以减轻儿童和成人在创伤后经历创伤后应激障碍（PTSD）的严重程度。然而，对于来自社区的高危青少年样本中社会支持的作用知之甚少。本研究在调整了潜在协变量的影响后，包括社会人口因素、先前的儿童逆境、暴露程度、共患焦虑、抑郁症状和物质滥用以及应对策略，研究了社会支持与暴露于创伤性事件和童年逆境的青少年 PTSD 症状之间的关系。
该研究的参与者为 183 名青少年，平均年龄为 16 岁（M=15.71，SD=1.31），年龄在 13 至 17 岁之间，89 名男性（48.6%）和 94 名女性（51.4%）。
研究结果显示，该样本中有 26.2%符合 PTSD 可能诊断标准。我们的统计模型解释了 PTSD 症状 64%的方差，但在调整协变量后，社会支持并不显著。本研究发现，在经历创伤和逆境的青少年中，社会支持不足以减轻 PTSD 症状。仅关注改善社会支持的计划可能对减轻青少年的心理健康症状无效，特别是在经历了严重和/或多种形式的儿童逆境时。
