目的
- 变革过度被认为是变革管理的一个重要方面。本文的目的是确定三个主要方面的变化过度：变化的频率，程度和影响。一个三因素的结构，建议扩大新兴的研究背景方面的变化。它的针对性提出了解决医疗保健员工的疲惫，变化相关的不确定性，并支持变革。
设计/方法/方式
- 使用问卷调查，第一个试点样本（n=131）被招募到测试的三因素结构的心理测量特性和效度，同时控制情感。在第二个样本（n=363）上使用了两步法后的结构方程建模技术。首先对过度变化的三因素结构进行验证性评估。第二，过度变化的完全中介作用，作为一个二阶潜在因素，重组变化的频率，影响和程度作为一阶因素，被建模预测的三个概念的变化相关的反应：枯竭，不确定性，和支持的变化。
结果
- 过度变化三因素结构得到验证，同时显示出其优于替代模型。证实了完全介导的模型。因此，改变频率、影响和程度的显著附加效应与情绪耗竭和认知不确定性正相关，而与改变的行为支持负相关。
独创性/价值
- 本研究的贡献，提出了一个三因素结构过度变化评估的基础上以前和独立的研究结果在文献中。它还有助于在建模的变化频率，程度和影响，在充分的中介关系的变化过度的三方反应，在医疗保健管理设置的变化的影响。
Purpose
– Change excessiveness is argued as a critical contextual aspect of change management. The purpose of this paper is to identify three major dimensions to change excessiveness: change frequency, extent, and impact. A three-factor structure is proposed to broaden the emerging study on the contextual aspects of change. Its pertinence is proposed in addressing healthcare employees’ exhaustion, change-related uncertainty, and support for change.
Design/methodology/approach
– Using questionnaires, a first pilot sample (n=131) was recruited to test the psychometric properties and validity of the three-factor structure, while controlling for affectivity. Structural equation modeling techniques following a two-step approach were used on a second sample (n=363). First a confirmatory assessment of the three-factor structure of excessive change is tested. Second, a full mediation effect of excessive change, as a second-order latent factor, regrouping change frequency, impact and extent as first-order factors, was modeled to predict a tripartite conception of change-related reactions: exhaustion, uncertainty, and support for change.
Findings
– The excessive change three-factor structure is validated, while showing its superiority over alternative models. The fully mediated model is confirmed. Therefore, the significant added effects of change frequency, impact, and extent are positively related to emotional exhaustion and cognitive uncertainty, while negatively related with behavioral support for change.
Originality/value
– This study contributes by proposing a three-factor structure to excessive change assessment based on previous and independent findings in the literature. It also contributes in modeling the added effect of change frequency, extent, and impact in the full mediation relationship of change excessiveness on a tripartite reactions to change in healthcare management settings.
