The interrater reliability, factorial and discriminant validity of a standardized and expanded Brief Psychiatric Rating Scale (BPRS-E) were investigated in a heterogeneous short-stay group of psychiatric inpatients in the Netherlands (n = 162). Repeated separate interviews by single clinicians (psychiatrists, residents or clinical psychologists), best reflecting the way the BPRS is usually employed in clinical practice and psychopharmacological research, were used to determine interrater reliability (n = 79). Although the 5 subscales of the original 18-item BPRS (BPRS-18) were successfully cross-validated in this Dutch sample, 4 of these subscales (except for thought disturbance) were found to lack interrater reliability. The 10-item schizophrenia scale derived from the BPRS-18 by a Scandinavian group met the standard of acceptable interrater reliability; BPRS-18 and BPRS-E global scales approximated this standard. For the thought disturbance subscale, the schizophrenia scale and for BPRS-18 and BPRS-E global scales, findings supported discriminatory power.
在荷兰一组异质性短期住院精神科患者（n = 162）中，对标准化且扩展的简明精神病评定量表（BPRS-E）的评定者间信度、因子效度和区分效度进行了研究。由单一临床医生（精神科医生、住院医生或临床心理学家）进行多次单独访谈，这最能反映BPRS在临床实践和精神药理学研究中的通常使用方式，以此来确定评定者间信度（n = 79）。尽管最初的18项BPRS（BPRS-18）的5个分量表在这个荷兰样本中成功进行了交叉验证，但发现其中4个分量表（思维紊乱分量表除外）缺乏评定者间信度。一个斯堪的纳维亚小组从BPRS-18衍生出的10项精神分裂症量表达到了可接受的评定者间信度标准；BPRS-18和BPRS-E的总量表接近这一标准。对于思维紊乱分量表、精神分裂症量表以及BPRS-18和BPRS-E的总量表，研究结果支持其区分能力。
