The current two-wave longitudinal study aimed to investigate changes in stress, anxiety, depression, and positive mental health (PMH) during the first COVID-19 pandemic outbreak in the sample of emerging adults. Data were collected before the COVID-19 and within the first month of the outbreak. The study sample consisted of 775 university students from Lithuania (n = 450, M _age(SD _age) = 19.45 (0.93), 79.3% female) and Germany (n = 325, M _age(SD _age) = 23.08 (2.94), 78.2% female). The results of multivariate Latent Change Analysis revealed that Lithuanian and German emerging adults demonstrated a decrease in stress and anxiety at the COVID-19 outbreak. Lithuanians also showed a decrease in depressive symptoms and an increase in PMH. Three groups with different change patterns were identified: resilient (82%) demonstrating positive changes, high-symptom (8%) with stable high rates of stress and depression and stable low rates of PMH, and vulnerable (10%) with an increase in depressive symptoms as well as a decrease in PMH over time.

目前的两波纵向研究旨在调查在第一次 COVID-19 大流行爆发期间新兴成年人样本中压力、焦虑、抑郁和积极心理健康 (PMH) 的变化。数据是在 COVID-19 之前和爆发的第一个月内收集的。研究样本包括来自立陶宛（n =450，M _年龄（SD _年龄）=19.45（0.93），79.3%为女性）和德国（n =325，M _年龄（SD _年龄））的775名大学生) = 23.08 (2.94)，78.2% 女性）。多元潜在变化分析的结果显示，立陶宛和德国的新兴成年人在 COVID-19 爆发时表现出压力和焦虑的减少。立陶宛人还表现出抑郁症状的减少和 PMH 的增加。确定了具有不同变化模式的三组：有弹性的(82%) 表现出积极的变化，高症状(8%) 具有稳定的高压力和抑郁率以及稳定的低 PMH 率，以及脆弱(10%) 与增加的随着时间的推移，抑郁症状以及 PMH 的减少。
