BACKGROUND: The self-rated, 16-item Quick Inventory of Depressive Symptomatology (QIDS-SR16) is a well-established measure of depression severity. This study aimed to evaluate the psychometric properties of the German translation of the QIDS-SR16.
METHODS: 332 depressed German adults awaiting psychotherapy were assessed with the German translations of the QIDS-SR16, the Beck Depression Inventory (BDI-II) and the 24-item Hamilton Rating Scale for Depression (HRSD-24).
RESULTS: Internal consistency for the QIDS-SR16 was acceptable (Cronbach's alpha = .77). Corrected item-total correlations indicated adequate discriminatory power of all the items. The QIDS-SR16 highly correlated with the BDI-II (r = .810) but only moderately correlated with the HRSD-24 (r = .581). Regarding discriminant validity, the QIDS-SR16 discriminated between patients with and without a depressive episode but not between patients with and without panic disorder.
CONCLUSION: The German translation of the QIDS-SR16 has adequate psychometric properties. Our results support the usefulness of the German version of the QIDS-SR16 as a brief depression rating scale in clinical and research settings.
