Results: The mental health impact of the COVID-19 pandemic on people with and without depressive, anxiety, or obsessive-compulsive disorders: a longitudinal study of three Dutch case-control cohorts

Online questionnaires sent out every 2 weeks to 2748 participants in the three studies: 85% of participants from NESDA, 4% from NESDO, and 11% from NOCDA; 1517 total answer at least once
Non respondents younger with lower education level and more likely to have preexisting mental illness, no difference by gender
Of 1517 respondents to online questionnaire, 1181 had lifetime mental health disorder (depressive, anxiety or OCD)
People with more severe or chronic mental health disorder reported greater impact on mental health, increased fear of COVID-19 and less positive coping, more sad emotions, unhealthy lifestyles, fear of infection, and less connection and confidence with society
Both before and after the pandemic the 4 symptom scores used were higher in those with more severe or chronic disorders
Compared to pre COVID conditions depressive symptoms, worry and loneliness increased during the pandemic
No significant change in anxiety
People without severe or chronic mental health problems generally showed modest increase in all 4 symptom scores while there was no overall increase in symptom severity for people with higher mental health burdens
