Parent and child mental health trajectories April-October 2020: Strict lockdown versus no lockdown in Australia
Objective: To control a second-wave COVID-19 outbreak, the state of Victoria in Australia experienced one of the world’s first long and strict lockdowns over July-October 2020, while the rest of Australia experienced ‘COVID-normal’ with minimal restrictions. We (1) investigate trajectories of parent/child mental health outcomes; and (2) identify baseline demographic, individual, and COVID-19-related factors associated with mental health trajectories. Method: Online community sample of 1,877 Australian parents with rapid repeated assessment over 10 time-points over April-October, 2020. Measures assessed parent mental health (Depression, Anxiety and Stress Scales-21); child depression symptoms (13-item Short Mood and Feelings Questionnaire); and child anxiety symptoms (four-items from Brief Spence Children’s Anxiety Scale).Results: Mental health trajectories shadowed COVID-19 infection rates. Victorians reported a large peak in mental health symptoms at the time of the second-wave lockdown compared to other states. Key baseline predictors, including parent and child loneliness (standardized regression coefficient [β]=·09-·39), parent/child diagnoses (β=·11-·22), couple conflict (β=·09-·19), and COVID-19 stressors, such as worry/concern about COVID-19, illness, and loss of job (β=·07-·22), predicted elevated trajectories. Effects of predictors on parent and child mental health trajectories are illustrated in an online interactive app for readers (https://lingtax.shinyapps.io/CPAS_trend/).Conclusion: Our findings provide evidence of worse trajectories of parent and child mental health symptoms associated with strict, sustained, COVID-19 lockdown in Victoria, compared to non-locked states in the rest of Australia. We identified several baseline factors that may be useful in detecting high risk families who are likely to require additional support early on in future lockdowns.
