Comparing psychological distress in Australians before and during the COVID-19 pandemic

Objective To determine if psychological distress has increased during the COVID-19 pandemic, and to identify predictors of distress. Method Kessler Psychological Distress Scale (K10) scores from nationally representative Australian samples before (n = 955) and during (n = 1173) the pandemic were compared. The pandemic sample also completed additional COVID-19 attitudinal scales. Results The pandemic sample reported significantly higher distress than the pre-pandemic sample, especially among Melbourne residents, women, and younger and older Australians. Stress attributed to COVID-19, feeling the pandemic management is out of control, and an unwillingness to vaccinate were also predictive of psychological distress. Conclusions Women, youth, and Melbourne residents were most vulnerable to the negative effects of COVID-19 on wellbeing, while feelings related to a loss of control, stress about the virus, and vaccine hesitancy may have also contributed to psychological distress.
