Data were weighted based on post‐stratification to facilitate generalization to Dutch population. Unadjusted model: OR and p not controlled for socio‐demographic differences between respondents interviewed before and during the pandemic. Adjusted model: aOR and p controlled for socio‐demographic differences (sex, age, education, living situation, employment status, urbanicity) between respondents interviewed before and during the pandemic. ADHD – attention‐deficit/hyperactivity disorder.
