Intolerance of Uncertainty as a Situational Vulnerability Factor in the Context of the Pandemic: A Systematic Review and Meta-Analysis of COVID-19-Related Psychological Impacts.

The findings support that IU is a higher order transsituational vulnerability factor related to cognitive, behavioural and distress responses during the pandemic. Limitations include English-language-only sources, reliance on a wide range of measures that were coded using a novel system and variable risk of bias across studies. The implications are considered in relation to the management of psychological consequences of major situational stressors experienced at a global scale, but the variations at a national and socioeconomic level also have implications for different or localized stressors at a regional or community level.
