Supplementary notes

* In 2018, the scale to measure anxiety disorders was switched from the Generalized Anxiety Disorder Scale (GAD-7) to the Patient Health Questionnaire (PHQ). Although the PHQ allows the comparison of figures on a European level, this represents a methodological break.

The figures have been taken from several publications, the number of participants therefore varied. Furthermore, the sampling of respondents was made online and not controlled scientifically. However, a logistic regression model based on age, gender, and the yearly population, was used to evaluate the prevalence of mental disorders in the entire Belgian population.

As any scale evaluating psychological problems, a margin of error is to be considered. The presented share of the population with a generalized anxiety disorder in Belgium is to be considered as a general picture of the situation across the country.
