An accumulating body of literature has shown a link between early pubertal maturation and internalizing problems, particularly among girls. Our knowledge is, however, limited with regard to what accounts for this association. Based on a hypothesis that early maturing girls have heightened stress sensitivity that increases the risk of internalizing problems, the present investigation examined the roles of pubertal timing and salivary cortisol reactivity to interpersonal stressors in adolescents' internalizing problems. Results from 110 boys and 106 girls (ages 11-16) indicated that early maturing adolescents had increased internalizing symptoms. Early maturing girls' higher levels of internalizing problems were at least partially attributed to their heightened sensitivity to interpersonal stress. Finally, girls' cortisol reactivity to interpersonal challenge was more strongly associated with internalizing problems than boys' reactivity.
越来越多的文献表明，青春期早期成熟与内化问题之间存在关联，尤其是在女孩中。然而，我们对于这种关联的原因知之甚少。基于一种假设，即早熟的女孩对压力更敏感，这增加了内化问题的风险，本研究探讨了青春期发育时间和唾液皮质醇对人际压力源的反应性在青少年内化问题中的作用。结果表明，110 名男孩和 106 名女孩（年龄 11-16 岁）的研究结果表明，早熟的青少年有更多的内化症状。早熟女孩内化问题的程度较高，至少部分归因于她们对人际压力更敏感。最后，女孩对人际挑战的皮质醇反应与内化问题的相关性强于男孩。
