目前的研究探讨了整个青春期的痛苦耐受性、感知压力和内化症状之间的关系。第一波研究的参与者包括 331 名 10 至 14 岁的青少年，在 5 年内每年进行一次评估。使用潜在增长曲线方法来测试三个研究问题，包括感知压力是否会在整个青春期增加，痛苦耐受性（通过行为任务测量）是否可以预测感知压力的变化，以及感知压力的变化是否会调节痛苦耐受性和内化症状之间的关系。结果表明，与之前的研究结果一致，青春期的感知压力率确实有所增加。此外，研究结果表明，基线时的痛苦不耐受预示着感知压力的增加，这反过来又导致内化症状的增加。这些发现指出了痛苦耐受性在引起抑郁和焦虑症状变化方面的关键作用，并建议支持利用负强化框架来理解内化症状的出现。
The current study examines the relation between distress tolerance, perceived stress, and internalizing symptoms across adolescence. Participants included 331 youth, ages 10 to 14 at the first wave of the study, assessed annually over 5 years. A latent growth curve approach was used to test three research questions, including whether perceived stress would increase across adolescence, whether distress tolerance (as measured by a behavioral task) would predict changes in perceived stress, and whether changes in perceived stress would mediate the relation between distress tolerance and internalizing symptoms. Results suggest that, consistent with previous findings, rates of perceived stress do increase across adolescence. Further, findings indicate that distress intolerance at baseline predicted increases in perceived stress, which in turn drove increases in internalizing symptoms. These findings point to the critical role of distress tolerance in bringing about changes in depression and anxiety symptoms and suggest support for utilizing a negative reinforcement framework to understand the emergence of internalizing symptomology.
