Time perception and suicidal ideation during COVID-19 pandemic: A longitudinal study.

BACKGROUND

There are several reports of disruptions in time perception during lockdown periods throughout the COVID-19 pandemic. Our aim was to study the role of subjective flow of time (SFT) in the triggering of suicidal ideation in patients with a history of suicide attempt (SA), as compared with affective controls without such history (AC).

METHODS

This study involved 296 psychiatric patients that were assessed five times between 2020 and 2021. We analyzed the SFT using a mixed logistic model and characterized SFT during significant periods of governmental restrictions. Multivariate logistic regressions were used to identify independent SFT characteristics. We evaluated the association between SFT and suicidal ideation, considering interactions with depression, insomnia, loneliness, and social support.

RESULTS

The findings revealed a significant alteration in SFT, closely linked to the implementation and easing of governmental restrictions. During the initial lockdown, SA exhibited lower SFT levels compared to AC. Furthermore, the relationship between SFT and suicidal ideation was influenced by depression. In the interim period between lockdowns, SFT's impact on suicidal ideation was mediated by insomnia.

DISCUSSION

Disturbances in SFT could be related to adaptability to lockdown conditions or may be a coping mechanism with depression, insomnia, suicidal ideation and overall psychological distress. Understanding the interplay of SFT with these factors provides crucial insights into the complex psychological mechanisms involved.
