The relationship between COVID-19-induced death thoughts and depression during a national lockdown

Evidence suggests that the COVID-19 pandemic has increased rates of depression worldwide. Many factors have been identified to relate to this increase depression, but according to Terror Management Theory, the heightened awareness of death during the pandemic has the potential to increase depression for those with low self-esteem. This hypothesis was examined in a U.K. sample during the first national lockdown where depression, self-esteem and death-thought accessibility (DTA) were measured, and a COVID Index (COVID-19 cases and deaths on date of participation) was produced. The COVID Index was positively related to DTA. Additionally, DTA mediated the relationship between the COVID Index and depression scores when participants had low levels of self-esteem. These findings suggest that heightened existential concerns may be a neglected factor increasing depression during the pandemic.

Towards an Anxiety-Buffer Disruption Approach to Depression: Attachment Anxiety and Worldview Threat Heighten Death-Thought Accessibility and Depression-Related Feelings

Introduction: In two studies, we tested an anxiety-buffer disruption approach to depression, examining the effects of attachment insecurities, worldview threat, and death concerns on depression-related feelings. Method: In both studies, Israeli undergraduates reported on their attachment insecurities (anxiety, avoidance), were exposed to a worldview threat or a no-threat condition, and then rated their current level of depression-related feelings. Results: In Study 1 (N = 124), we also measured death-thought accessibility and found that a worldview threat (versus no-threat) heightened death-thought accessibility and depression feelings only among participants scoring relatively high on attachment anxiety, and that death-thought accessibility mediated the effects of worldview threat and attachment anxiety on feelings of depression. In Study 2 (N = 240), we randomly assigned participants to a mortality salience or a control condition and found that heightened death concerns caused more depression only when a worldview threat was present and participants' attachment anxiety was high. Discussion: The roles that disruption of anxiety buffering systems and death-related concerns play in depression were discussed.

Exploring the role of humor in the management of existential anxiety

The current study addressed a topic that has both theoretical and applied importance, by examining the potential existential anxiety-buffering function of humor. Participants (N = 556; 55% female; M age = 37 years) completed a measure of trait coping humor before being randomly assigned to a mortality salience condition and a humor induction condition and then completing a measure of death-thought accessibility. ANOVA revealed main effects of trait coping humor, mortality salience and humor induction on death-thought accessibility in the expected directions. Coping humor interacted with mortality salience (F(1,439) = 14.47, p < 0.01) showing that low coping humor participants were more affected by the mortality salience manipulation. Coping humor also interacted with humor induction (F(1,439) = 8.94, p < 0.01) showing that low coping humor participants were more affected by the humor induction. Findings suggests that whilst trait coping humor appears to buffer the effects of mortality salience, those low in trait coping humor may benefit the most from interventions aimed at reducing existential anxiety via humor. The apparent beneficial effect of humor induction for individuals low in coping humor holds a promise of advancing our understanding of existential threat and, ultimately, providing a basis for interventions to improve mental health.
