BACKGROUND
Hamilton depression rating scale (Ham-D) is the most widely used clinician rating scale for depression. There has been no Indian study that has examined the inter-rater reliability (IRR) of video-recorded interviews of the 21-item Ham-D.
AIM
To study the IRR of scoring video-recorded interviews for 21-item Ham-D.
MATERIALS AND METHODS
Eighteen subjects with major depressive disorder involved in a larger study were interviewed using the semi-structured clinical interview of the 21-item Ham-D by a primary rater after informed consent. These interviews were video-recorded and portions edited to ensure rater blinding. Subsequently, the video-recorded interviews were rated by a "blind" rater. Both rated the different sub-domains of Ham-D according to Rhoades and Overall (1983). IRR was evaluated using intra-class correlation coefficient.
RESULTS
Excellent IRR was observed (0.9891) between the two raters. This was true for each of the primary factors and super-factors.
CONCLUSION
Video recorded 21-item Ham-D has excellentIRR. Video-recorded interviews of Ham-D can be reliably used to blind raters in research.
背景
汉密尔顿抑郁评定量表（Ham-D）是最广泛用于评估抑郁症的临床医生评定量表。目前还没有印度研究检验过 21 项汉密尔顿抑郁量表的视频记录访谈的评分者间信度（IRR）。
目的
研究 21 项汉密尔顿抑郁量表的视频记录访谈的评分者间信度。
材料和方法
18 名患有重度抑郁症的受试者在知情同意后，由主要评估者使用半结构式临床访谈 21 项汉密尔顿抑郁量表对他们进行访谈。这些访谈被录像，并剪辑部分内容以确保评估者盲法。随后，录像访谈由一名“盲”评估者进行评分。两位评估者均根据 Rhoades 和 Overall（1983）的方法对汉密尔顿抑郁量表的不同子域进行评分。使用组内相关系数评估 IRR。
结果
两位评估者之间观察到极好的 IRR（0.9891）。这对于主要因素和超因素中的每一个都是如此。
结论
视频记录的 21 项汉密尔顿抑郁量表具有极好的评分者间信度。汉密尔顿抑郁量表的视频记录访谈可以可靠地用于研究中的盲法评估者。
