Abstract:
:Current standards for treating major depressive disorder (MDD) recommend that achieving remission should be considered the principal goal of treatment. Recent research suggests that the symptom-based definitions of remission used in efficacy studies do not adequately reflect the perspective of depressed patients receiving treatment in routine clinical settings. We developed the Remission from Depression Questionnaire (RDQ) to capture the broader array of domains considered by patients to be relevant to the construct of remission--symptoms of depression, nondepressive symptoms, features of positive mental health, coping ability, functioning, life satisfaction and a general sense of well-being. The current report is the first study of the reliability and validity of the RDQ. The test-retest reliability of the RDQ was studied in 60 depressed outpatients in ongoing treatment. The convergent and discriminant validity of the RDQ was studied in 274 depressed outpatients who were rated on the 17-item Hamilton Depression Scale (HAM-D) and who completed several self-report scales including the Quick Inventory of Depressive Symptomatology (QIDS). The RDQ demonstrated excellent internal consistency, with a Cronbach's α of .97 for the total scale and above .80 for each of the 7 subscales. The test-retest reliability of the total scale was .85 and above .60 for each subscale. Both the RDQ and QIDS were significantly associated with patients' self-reported remission status. However, the RDQ remained significantly associated with remission status after controlling for QIDS scores (r = -.32, p < .001) whereas the QIDS was not associated with remission status after controlling for RDQ scores (r = -.06). The RDQ is a reliable and valid measure that evaluates the multiple domains that depressed patients consider important in determining remission. The results are consistent with prior research suggesting that depressed patients' perspective of remission goes beyond symptom resolution.
