summary
background The Diagnostic Inventory for Depression (did) is a new self-report questionnaire based on the dsm-iv inclusion criteria for a major depressive disorder.
aim To analyse the Dutch translation of the did and examine the psychometric properties of the inventory.
methods We conducted a large-scale internet-based screening among the general population.
results Reliability, convergent validity and factor structure were good. The did-nl may classify participants accurately.
conclusion The results look promising and the did-nl can give added value to existing questionnaires. However, since the classification potential has not yet been sufficiently demonstrated, a clinical interview will still be needed.
