Concept

Procedures: 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

  • Information was collected on age, gender, and education of study participants.
  • NESDA and NESDO diagnosed mental health disorders using the DSM-IV-based Composite Interview Diagnostic Instrument.
  • NOCDA diagnosed OCD using the Structured Clinical Interview for DSM-IV Axis I Disorders.
  • The mental health burden was classified by severity and chronicity.
  • Scales for assessing the severity of the mental health burden included: the 16-item QIDS for depressive symptoms, 21-item BAI for anxiety, 11-item PSWQ for worry, and 6-item DJGLS for loneliness.
  • An online Survalyzer questionnaire was used to assess living situation, COVID-19 diagnosis, current or suspected mental health treatment, and the impact of the pandemic on mental health, emotional state, and coping.
