In a previous study which made a comparison between disorder-specific and generic instruments to assess outcome of treatments for depression, the Beck Depression Inventory, Second Edition (BDI-II) seemed to be more sensitive to change than the Inventory of Depressive Symptoms- Self Rating (IDS-SR).
A set with longitudinal data from Routine Outcome Monitoring (n=144) were analyzed with multilevel models with random intercepts. The sensitivity to change of two disorder-specific instruments, the BDI-II and the IDS-SR, were compared head to head.
The BDI-II was more sensitive to change when measuring treatment outcome compared to the IDS-SR. The BDI-II decreases significantly more over time than the IDS-SR: the average decrease per week for the IDS-SR is -.012 (95%CI -0.015, -0.009) and for the BDI-II it is -.017 (95%CI -0.021, -0.014).
Conclusions can only be preliminary due to a small sample size.
Treatment outcomes measured with questionnaires may differ depending on the degree of sensitivity to change of the instruments.
在之前一项比较专门用于评估抑郁症治疗效果的量表和通用量表的研究中，贝克抑郁量表第二版（BDI-II）似乎比抑郁症状自评量表-自我报告版（IDS-SR）更能敏感地反映变化。
本研究使用具有纵向数据的常规结果监测（n=144），采用随机截距的多水平模型进行分析。专门用于评估抑郁症的两种量表（BDI-II 和 IDS-SR）的变化敏感性进行了直接比较。
与 IDS-SR 相比，BDI-II 在测量治疗效果时更能敏感地反映变化。BDI-II 随时间的下降幅度明显大于 IDS-SR：IDS-SR 每周的平均下降值为 -.012（95%CI -0.015，-0.009），而 BDI-II 则为 -.017（95%CI -0.021，-0.014）。
由于样本量较小，结论只能是初步的。
使用问卷测量的治疗效果可能因量表的变化敏感性程度而异。
