This paper examines how a deeper understanding of procedural justice and interactional justice can enhance the effectiveness of causal mapping workshops using Group Explorer® software combined with the Decision Explorer® tool. A dual facilitation model is outlined that explicitly links the determinates of procedural justice and the key elements of interactional justice to the stages of causal mapping workshops. This model serves to illustrate how the participants’ voice in group workshops using causal mapping is strengthened, producing an authentic outcome that more accurately represents participants’ thinking. Enabling the determinants in the model supports the dimensions of procedural and interactional justice, ensuring these more authentic outcomes. A link between these determinants, dimensions and the workshop process is confirmed through qualitative and quantitative analysis. The qualitative analysis draws on causal maps created with relevant concepts/ statements, highlighted to illustrate this more authentic voice. The quantitative work analyses responses to a post-workshop questionnaire using scale reduction techniques and looks for significant relationships between participants’ voice and the determinants of procedural justice, interactional justice and the causal mapping approach adopted.

本文研究了如何通过使用GroupExplorer®软件和DecisionExplorer®工具结合对程序正义和交互正义的更深入了解来提高因果映射研讨会的效率。概述了双重促进模型，该模型将程序正义的确定性和互动正义的关键要素明确地联系到因果制图研讨会的各个阶段。该模型用于说明如何使用因果映射来增强参与者在小组研讨会中的声音，从而产生能够更准确地代表参与者思维的真实结果。在模型中启用决定因素可支持程序正义和互动正义的各个方面，从而确保这些更为真实的结果。这些决定因素之间的联系，尺寸和车间过程通过定性和定量分析得到确认。定性分析利用以相关概念/陈述创建的因果图，突出显示该因果图以说明这种更为真实的声音。量化工作使用规模缩减技术来分析对车间后调查表的答复，并寻找参与者的声音与程序正义，互动正义和所采用的因果映射方法的决定因素之间的重要关系。
