背景和目的。为了确定三级量表数据的可靠性和有效性，研究者提出了两种简化的三级平衡量表——修正Berg平衡量表（BBS- 3p）和修正的卒中患者体位评估量表（PASS- 3p），并将每种量表的心理测量特性与原始量表（Berg平衡量表[BBS]和卒中患者体位评估量表[PASS]）进行比较。分别)。研究对象和方法。本研究由两部分组成。第一部分检验了用这些仪器获得的测量结果的可靠性和并发和收敛效度。共有77名患者参与了这部分研究。BBS中心的3个层次被折叠成一个层次（即0-2-4），形成BBS- 3p。同样，将PASS中间的2个分数取平均值（即0-1.5-3），形成PASS- 3p。在研究的第二部分，这些措施的预测效度和反应性进行了检验。从卒中后生活质量研究参与者的记录中检索226例患者的BBS和PASS评分，并将这些评分转换为拟议的BBS- 3p和PASS- 3p评分。结果。BBS- 3p和PASS- 3p与BBS和PASS具有较高的并发效度，对残疾有较好的预测效度，反应性中至高。重要的是，BBS- 3p和PASS- 3p的心理测量特性与原始BBS和PASS基本相同。讨论与结论。两种简化的3级平衡量表的心理测量特性与完整的、未截断的量表相当。未来的研究需要探讨从尺度简化方案中可以获得多少有意义的效用。王超，薛晓明，沈春春，等。用于脑卒中患者的2种简化3级平衡量表的心理测量特性。
Background and Purpose. To determine if the 3-level scales yield data as reliable and valid as data obtained for the original scales, 2 simplified 3-level measures of balance-a modified Berg Balance Scale (BBS-3P) and a modified Postural Assessment Scale for Stroke Patients (PASS-3P)-were proposed by the researchers, and psychometric properties of each were compared with those of the original measures (the Berg Balance Scale [BBS] and the Postural Assessment Scale for Stroke Patients [PASS], respectively) in patients with stroke. Subjects and Methods. The study consisted of 2 parts. The first part examined the reliability and concurrent and convergent validity of measurements obtained with these instruments. A total of 77 patients participated in this part of the study. The 3 levels in the center of the BBS were collapsed to a single level (ie, 0-2-4) to form the BBS-3P. Similarly, the 2 middle scores of the center of the PASS were averaged (ie, 0-1.5-3) to form the PASS-3P. In the second part of the Study, the predictive validity and responsiveness of these measures were examined. The BBS and PASS scores of 226 patients were retrieved from the records of participants in the Quality of Life After Stroke Study, and these scores were converted into the proposed BBS-3P and PASS-3P scores. Results. The BBS-3P and PASS-3P showed high concurrent validity with the BBS and PASS, good predictive validity for disability, and moderate to high responsiveness. Importantly, the psychometric properties of the BBS-3P and PASS-3P were essentially identical to those of the original BBS and PASS. Discussion and Conclusion. The psychometric properties of both simplified 3-level balance measures were comparable to those of the full, nontruncated scales. Future study is needed to investigate how much meaningful utility can be gained from the scheme of simplification of scaling. [Wang CH, Hsueh IT, Shen CF, et al.
