Sample Characteristics

Parents reported on child characteristics (i.e., age, gender, school grade and co-occurring conditions), and on their individual and family characteristics (i.e., age, gender, area of residence, country of birth, Aboriginal or Torres Strait Islander status, language spoken at home, relationship to the child, partner status, number of children at home ≥ 50% of the time, education and qualifications completed, pre-COVID-19 employment status and changes to work situation since COVID-19). Study-designed questions captured the child’s current medications, and were collapsed into an antidepressant medication (e.g., fluoxetine, sertraline, escitalopram; yes/no), and a stimulant and/or non-stimulant medication for ADHD (methylphenidate, lisdexamfetamine, dexamphetamine, guanfacine, atomoxetine; yes/no). The Socio-Economic Indexes for Areas (SEIFA) is presented for participants, which ranks areas of Australia according to the relative level of socio-economic disadvantage based on geographical area [33]. SEIFA scores are standardised (M = 1,000, SD = 100), where higher scores indicate relative socio-economic advantage.
