A Self-Report Measure of ICD-11 Depressive Disorder
The International Depression Questionnaire (IDQ) is a self-report measure of ICD-11 Single Episode Depressive Disorder (ICD-11 diagnostic code 6A70).
It can be used to generate severity scores and to identify cases meeting diagnostic requirements. The severity scoring method involves summing the scores of the 9 IDQ items, producing a possible range of scores from 0 to 36.
No cut-off scores are proposed as caseness is defined by applying the ICD-11 diagnostic algorithm.
The IDQ is freely available to all interested parties.
