COVID-19 has impacted the world on a psychological level. With cases continuing to rise, understanding mental health and vulnerability factors are vital for researchers and mental health professionals to address. This study examines personality factors—using a person-centered approach compared to the majority of studies that use a variable-centered approach—to investigate the psychological impacts of COVID-19 on people's fear, stress, sleep quality and activities during lockdown. The study, conducted among a Bangladeshi sample from April 17 to 20, 2020, contained n = 521 participants. Latent profile analysis identified three personality profiles – maladaptive, adaptive, and highly adaptive. Results indicated that participants with a highly adaptive personality profile exhibited lower COVID-19 fear and perceived stress as well as better sleep quality compared to the other personality profiles. Our findings yield support for person-centered approaches to personality in relation to COVID-19 experiences, which can be beneficial for researchers and mental health professionals alike in understanding these psychological interworkings.

COVID-19 在心理层面上影响了世界。随着病例的持续增加，了解心理健康和脆弱因素对于研究人员和心理健康专业人员来说至关重要。与大多数使用以变量为中心的方法的研究相比，本研究使用以人为中心的方法检查人格因素，以调查 COVID-19 对人们在锁定期间的恐惧、压力、睡眠质量和活动的心理影响。该研究于 2020 年 4 月 17 日至 20 日在孟加拉国样本中进行，包含n = 521 名参与者。潜在特征分析确定了三种人格特征——适应不良、适应性和高度适应性。结果表明，与其他人格特征相比，具有高度适应性人格特征的参与者表现出较低的 COVID-19 恐惧和感知压力以及更好的睡眠质量。我们的研究结果支持与 COVID-19 经历相关的以人为本的人格方法，这可能有助于研究人员和心理健康专家等人理解这些心理相互作用。
