Stress is known to amplify the link between pubertal timing and psychopathology. However, few studies have examined the role of peer stress as a context for this link. The present study examined the interaction between perceived pubertal timing and peer stress on symptoms of psychopathology in early adolescence. The sample consisted of 264 students (63% female; M (age) = 12.40, SD = 1.00; 55% Caucasian, 23% African American, 7% Latino, 11% biracial and 4% other). Higher peer stress was associated with symptoms of anxiety/depression; this effect did not vary by timing or gender. However, early-maturing girls with high peer stress demonstrated higher rates of relational and overt aggression compared to other girls. Findings also suggested that late-maturing boys with high stress are at risk for aggression problems; however, due to the small number of boys, analyses were exploratory. Overall, results suggest that developmentally salient contexts as indicated by stressful peer experiences may pose unique threats to early maturing girls and possibly late-maturing boys.
压力被认为放大了青春期时间和精神病理学之间的联系。然而，很少有研究探讨同伴压力作为这种联系的背景的作用。本研究考察了感知的青春期时间和同伴压力对青少年早期精神病理学症状的相互作用。样本由 264 名学生（63%为女性；M（年龄）=12.40，SD=1.00；55%为白种人，23%为非裔美国人，7%为拉丁裔，11%为混血儿，4%为其他种族）组成。较高的同伴压力与焦虑/抑郁症状有关；这种效应不受时间或性别影响。然而，具有高同伴压力的早熟女孩比其他女孩表现出更高的关系和公开攻击率。研究结果还表明，高压力的晚熟男孩有攻击性问题的风险；然而，由于男孩人数较少，分析是探索性的。总的来说，研究结果表明，以压力大的同伴经历为特征的发展性突出背景可能对早熟女孩和可能晚熟的男孩构成独特的威胁。
