Within-patient change and linear regression anchor-based analyses were conducted to define meaningful and substantial changes in the HRSD 17 and HRSD 6 using three patient-reported outcomes [Work and Social Adjustment Scale (WSAS), Quality of Life Enjoyment and Satisfaction-Short Form (Q-LES-Q-SF); Mini-Q-LES-Q] obtained at baseline and exit from the first treatment step in STAR*D.Results: Linear regression analyses identified a meaningful change threshold for the HRSD 17 as 3.9 [3.7– 4.1] [lower, upper 95% CI] and a substantial change as 7.8 [7.4– 8.3] with the WSAS. Analogous thresholds based on the Q-LES-Q-SF were 5.8 [5.5– 6.1] and 11.6 [11.0– 12.2], respectively, and 4.9 [4.7– 5.2] and 9.9 [9.3– 10.4] for the Mini-QLES-Q, respectively. For the HRSD 6, linear regression analyses with the WSAS identified a meaningful change as 2.2 [2.1– 2.4], while a substantial change was 4.5 [4.2– 4.7]. Analogous figures based on the Q-LES-Q-SF were 3.2 [3.0– 3.4] and 6.4 [6.1– 6.8]. Similarly, based on the Mini-QLESQ, results were 2.8 [2.6– 2.9] and 5.6 [5.3– 5.9]. For both the HRSD 17 and the HRSD 6, within-patient analyses produced less precise estimates of the same change thresholds with substantial overlap between groups. Based on the WSAS, a clinically meaningful change in the HRSD 17 total score was 9.6 (SD = 6.5), while a substantial change was 15.0 (SD = 6.7). Analogous change thresholds based on the Q-LESQ-SF were 12.9 (SD = 6.2) and 16.8 (SD = 6.4), respectively. For the Mini-Q-LES-Q, thresholds were 10.9 (SD = 6.5) and 16.1 (SD = 6.2).Conclusion: A 4– 6 point change in the HRSD 17 is clinically meaningful; a 7– 12 point change is clinically substantial. For the HRSD 6, analogous estimates were 2– 3 and 4– 7 point changes, respectively.Keywords: depression ratings, patient-reported outcomes, meaningful change |
