Abstract
The lockdown due to the coronavirus outbreak in 2019 (COVID‐19) has caused psychological distress and cognitive discomfort for emerging adults, who have experienced increased rumination, intrusive thoughts and cognitive failures. States of mindfulness and being in the moment can prevent anxiety and fear associated with the lockdown and alleviate ruminative and automatic negative thinking. This longitudinal study investigated the role of mindfulness before and during the COVID‐19 lockdown in protecting a sample of emerging adults from experiencing cognitive failures, intrusive thoughts and rumination and examined how lockdown‐related variables—emotions, socio‐economic status and housing conditions—influenced this mindfulness profile. The results showed overall more cognitive failures and rumination during lockdown, especially in participants whose mindfulness status diminished. However, these signs of cognitive distress remained stable or decreased among participants who reported improved changes in mindfulness. Financial difficulties and a reduced sense of privacy associated with the lockdown predicted lower stability in mindfulness profiles. The state of being fully aware of what is happening in the present moment may be helpful in reducing cognitive discomfort and psychological maladjustment, especially during stressful times such as lockdowns.
