Existing literature on how employment loss affects depression has struggled to address potential endogeneity bias caused by reverse causality. The COVID-19 pandemic offers a unique natural experiment because the source of unemployment is very likely to be exogenous to the individual. This study assessed the effect of job loss and job furlough on the mental health of individuals in South Africa during the COVID-19 pandemic.
The data for the study came from the first and second waves of the national survey, the National Income Dynamics-Coronavirus Rapid Mobile Survey (NIDS-CRAM), conducted during May-June and July-August 2020, respectively. The sample for NIDS-CRAM was drawn from an earlier national survey, conducted in 2017, which had collected data on mental health. Questions on depressive symptoms during the lockdown were asked in Wave 2 of NIDS-CRAM, using a 2-question version of the Patient Health Questionnaire (PHQ-2). The PHQ-2 responses (0-6 on the discrete scale) were regrouped into four categories making the ordered logit regression model the most suited for assessing the impact of employment status on depressive symptoms.
The study revealed that adults who retained paid employment during the COVID-19 lockdown had significantly lower depression scores than adults who lost employment. The benefits of employment also accumulated over time, underscoring the effect of unemployment duration on mental health. The analysis revealed no mental health benefits to being furloughed (on unpaid leave), but paid leave had a strong and significant positive effect on the mental health of adults.
The economic fallout of the COVID-19 pandemic resulted in unprecedented job losses, which impaired mental wellbeing significantly. Health policy responses to the crisis therefore need to focus on both physical and mental health interventions.
现有关于失业如何影响抑郁的文献难以解决由反向因果关系引起的潜在内生性偏差。COVID-19 大流行提供了一个独特的自然实验,因为失业的原因很可能是个体之外的因素。本研究评估了 COVID-19 大流行期间南非个人失业和休假对其心理健康的影响。
本研究的数据来自全国调查的第一波和第二波,即国家收入动态冠状病毒快速移动调查(NIDS-CRAM),分别于 2020 年 5 月至 6 月和 7 月至 8 月进行。NIDS-CRAM 的样本是从 2017 年进行的一项早期全国调查中抽取的,该调查收集了心理健康数据。在 NIDS-CRAM 的第二波调查中,使用患者健康问卷(PHQ-2)的 2 个问题版本询问了封锁期间的抑郁症状。PHQ-2 反应(离散量表上的 0-6)被重新分组为四个类别,这使得有序逻辑回归模型最适合评估就业状况对抑郁症状的影响。
研究表明,在 COVID-19 封锁期间保留有薪工作的成年人的抑郁评分明显低于失业的成年人。就业带来的好处也随着时间的推移而积累,突出了失业持续时间对心理健康的影响。分析表明,休假(无薪休假)对心理健康没有好处,但带薪休假对成年人的心理健康有很强且显著的积极影响。
COVID-19 大流行造成了前所未有的失业,对心理健康造成了重大影响。因此,应对危机的卫生政策需要关注身体和心理健康干预。
