On the Measurement and Control of Beta Change: Problems with the Bedeian, Armenakis, and Gibson Technique
讨论了组织发展面板设计中，受访者可能重新校准评分量表（β变化）或重构概念（γ变化）的问题，并比较了两种控制方法，指出Bedeian等人的方法存在严重的解释问题。
The evaluation of change in OD panel designs is complicated by the possibility that the respondent might have recalibrated the rating scale (beta change) or reconceptualized the construct (gamma change). Two different techniques now exist that claim to identify and control for these problems when the individual is the unit of analysis: that of Terborg, Howard, and Maxwell and that of Bedeian, Armenakis, and Gibson. Advantages and disadvantages of both techniques are reviewed. It is concluded that serious problems of interpretation can result with the Bedeian, Armenakis, and Gibson technique.
