The findings published to date on convergent validity of the BRMS are mainly concerned with the correlation with other observer-rating scales for depression. In many studies on the evaluation of therapeutic interventions self-rating scales are used in connection with observer-rating scales. Therefore, findings on the relations among instruments of both groups are necessary in order to justify the combination of a particular observer-rating scale with a particular self-rating scale. In the ICD-10 three different degrees of severity of depressive episodes are distinguished. No data on the discriminant validity of the BRMS with respect to this new diagnostic classification are available till now.
45 depressed inpatients were assessed with two observer-rating scales (BRMS and DEPRES of the AMDP system) and two self-rating scales (BDI and DS).
The discriminant validity with reference to the three degrees of severity of depressive episodes as defined in ICD-10 is at r = 0.80 very high. The convergent validity of the BRMS is high at r = 0.70, related to the DEPRES. The correlations between the BRMS and the BDI as well as the DS were clearly lower, at 0.53 and 0.32 each.
The only moderate convergent validity between self-rating and observer-rating scales is a strong argument for a multi-methodological approach in the context of therapy evaluation.
迄今为止发表的关于简明躁狂量表（BRMS）收敛效度的研究结果主要涉及与其他抑郁观察评定量表的相关性。在许多治疗干预评估研究中，自评量表与观察评定量表联合使用。因此，为了证明特定观察评定量表与特定自评量表的组合合理，有必要了解两组量表之间的关系。在《国际疾病分类第10版》（ICD - 10）中，区分了抑郁发作的三种不同严重程度。目前尚无关于BRMS相对于这种新诊断分类的区分效度的数据。
对45名住院抑郁症患者使用两种观察评定量表（BRMS和AMDP系统的DEPRES）和两种自评量表（BDI和DS）进行评估。
相对于ICD - 10中定义的抑郁发作的三种严重程度，区分效度非常高，r = 0.80。BRMS与DEPRES的收敛效度较高，r = 0.70。BRMS与BDI以及DS之间的相关性明显较低，分别为0.53和0.32。
自评量表与观察评定量表之间仅具有中等程度的收敛效度，这有力地支持了在治疗评估中采用多方法学途径。
