Background: The global COVID-19 pandemic rapidly and drastically impacted everyday life and relationships. Fear of contracting and spreading the virus brought governments and individuals to adopt strict social distancing measures. These changes have had a significant negative impact on mental health, including a suggested increase in suicidal behaviors. The present study examined the role of interpersonal stress and connectedness in suicidal ideation, deliberate self-harm, suicide attempts, and the suicide crisis syndrome during the COVID-19 pandemic. Methods: An international sample of 7837 adult participants was recruited across ten participating countries to complete an anonymous online battery of self-report questionnaires. Questionnaires assessed suicide-related outcomes, stressful life events (SLE), and connectedness. Multilevel regression analyses were used to examine the associations between SLE and connectedness on suicide-related outcomes within the past month. Results: Interpersonal SLEs and low connectedness were associated with an increased likelihood of suicide-related outcomes and increased severity of suicide crisis syndrome. Specifically, higher rates of SLEs and lower levels of connectedness were associated with more suicide-related outcomes. Limitations: The use of a cross-sectional design and snowball sampling method may restrict the ability to establish causal relationships and limit the representativeness of the findings. Conclusions: Our findings suggest elevated suicide-related outcomes during the COVID-19 pandemic among individuals experiencing multiple interpersonal stressful life events and low connectedness with others. The circumstances of social life during the COVID-19 pandemic highlight the urgency of implementing preventive programs aimed at mitigating potential suicide risks that may arise in the aftermath of public stress situations.
