Generalized Anxiety Disorder 7-item (GAD-7, Dutch
version)26
The GAD-7 assesses anxiety symptoms. It consists of 7 items, each scored
as 0 (‘not at all’), 1 (‘several days’), 2 (‘more than half of the
days’) or 3 (‘nearly every day’). Total scores range from 0 to 21;
scores of 5, 10 and 15 points are used as cut-off points for mild,
moderate, and severe anxiety, respectively. The GAD-7 has excellent
psychometric properties, including strong internal consistency
(Cronbach’s α = .85) and convergent validity with DSM-V diagnostic
criteria. Using a cut-off score of 10 or higher, sensitivity was 0.89
and specificity 0.82.26, 27
