Abstract

The Borg centiMax scale is a psychophysically constructed general intensity scale with verbal anchors placed in congruence with the numerical scale (0–100); thus, ratio data are obtained. With ratio data, quantitative relationships among perceptions and feelings can be determined in a statistically more solid way. The purpose of this pilot study was to explore the utility of using the Borg CR Scale® (centiMax^®, CR100) for measuring depressive symptoms in a pilot study of 50 students, who completed the centiMax along with the Beck Depression Inventory (BDI). Convergent validity and reliability were examined by correlation analyses (Pearson, Spearman, and Split-half with Spearman–Brown correction), and group and individual symptom profiles were constructed to illustrate the possible advantage of level anchored ratio data. The strong correlation 0.75 (p < .001) between the instruments supports an acceptable convergent validity of the centiMax and indicates a common underlying construct. Additionally, the reliability was high (cM = 0.96; BDI = 0.90). With symptom profiles, it was demonstrated that level anchored ratio data can show both how intense (level) and how many times more intense (relation) the feelings of separate symptoms are. In conclusion, the centiMax appears to be a valid and reliable instrument; however, further studies in larger samples including clinically depressed participants are needed for evaluating its diagnostic importance.

摘要

Borg centiMax量表是从心理上构造的一般强度量表，其中的言语锚与数字量表（0-100）一致；因此，获得比率数据。利用比率数据，可以以统计上更可靠的方式确定感知和感觉之间的定量关系。这项试验研究的目的是探讨使用博格CRScale®的实用程序（centiMax ^®，CR100）用于对50名学生进行的一项抑郁研究中的抑郁症状测量，他们完成了centiMax以及贝克抑郁量表（BDI）。通过相关性分析（Pearson，Spearman和使用Spearman-Brown校正的Split-half）检查收敛性有效性和可靠性，并构建组和个体症状概况以说明水平锚定比率数据的可能优势。 仪器之间的强相关性0.75（p <.001）支持centiMax的可接受收敛效度，并指示常见的基础构造。此外，可靠性很高（cM = 0.96； BDI = 0.90）。与症状谱，证明该水平锚定比率数据可以同时显示如何强烈（电平）和多少倍强烈（相关）的症状是分开的。总之，centiMax似乎是一种有效且可靠的工具。但是，需要对包括临床抑郁症患者在内的较大样本进行进一步研究，以评估其诊断重要性。
