The current study investigated the association between cortisol stress reactivity to a social stressor and observed socially anxious behaviors both concurrently and over time among previously institutionalized (PI) (N = 132; ages 7-17) youth and a comparison non-adopted (NA) sample (N = 176). Cortisol reactivity was captured during the Trier Social Stress Test for Children (TSST-C; Yim et al., 2015) and youths' social anxiety behaviors were coded during the speech portion of the TSST-C. Autoregressive cross-lagged panel models with structured residuals showed that for PI youth, greater cortisol reactivity predicted increases in socially anxious behavior during the TSST-C across three sessions. However, greater cortisol reactivity was negatively associated with concurrent social anxiety behavior. Thus, increases in cortisol reactivity across adolescence may aid in behavioral control in social situations in the short-term but may exacerbate PI youths' socially anxious behavior over time. No significant associations emerged for NA youth.
本研究调查了皮质醇对应激源的反应性与观察到的社交焦虑行为之间的关系，同时考察了之前被机构收容的（PI）（N=132；年龄 7-17 岁）青年和比较非收养（NA）样本（N=176）的这种关系。皮质醇反应性是在儿童 Trier 社会应激测试（TSST-C；Yim 等人，2015 年）中捕捉到的，而青年在 TSST-C 的演讲部分的社会焦虑行为被编码。带有结构残差的自回归交叉滞后面板模型显示，对于 PI 青年，皮质醇反应性越大，在三个阶段的 TSST-C 中，社交焦虑行为的增加幅度越大。然而，皮质醇反应性与同时的社交焦虑行为呈负相关。因此，青春期皮质醇反应性的增加可能有助于短期社交情境中的行为控制，但随着时间的推移，可能会加剧 PI 青年的社交焦虑行为。NA 青年没有出现显著的关联。
