This research examined personal-accentuation and contextual-amplification models of pubertal timing, wherein personal and contextual risks magnify the effects of earlier pubertal maturation on youth depression. A sample of 167 youths (M age = 12.41 years, SD = 1.19) and their maternal caregivers completed semistructured interviews and questionnaires at two waves. Consistent with a personal-accentuation model, earlier pubertal maturation more strongly predicted subsequent depression in youths with prior depression, certain personality traits, and maladaptive stress responses than in youths without these personal risks. Several of these effects were specific to earlier-maturing girls. Consistent with a contextual-amplification model, earlier pubertal maturation more strongly predicted subsequent depression in youths exposed to recent maternal depression and family stress than in youths without these contextual risks. These findings identify key characteristics of youths and their family context that help to explain individual variation in depressive reactions to earlier pubertal maturation. More broadly, this research contributes to integrative models of depression that consider the interplay among personal vulnerability, contextual risk, and developmental transitions.
本研究检验了青春期启动的个人突显和情境放大模型，其中个人和情境风险放大了青春期提前对青少年抑郁的影响。在两个时间点上，167 名青少年（M 年龄=12.41 岁，SD=1.19）及其母亲照顾者完成了半结构化访谈和问卷调查。与个人突显模型一致，与没有这些个人风险的青少年相比，先前有抑郁、某些人格特质和适应不良的应激反应的青少年中，青春期提前与随后的抑郁有更强的相关性。其中一些影响仅存在于青春期提前的女孩中。与情境放大模型一致，与没有这些情境风险的青少年相比，近期母亲抑郁和家庭压力暴露的青少年中，青春期提前与随后的抑郁有更强的相关性。这些发现确定了青少年及其家庭环境的关键特征，有助于解释对青春期提前的抑郁反应的个体差异。更广泛地说，这项研究为考虑个人脆弱性、情境风险和发展转变相互作用的抑郁综合模型做出了贡献。
