In the present research, we introduce and validate a single‐item measure of identity leadership—the visual identity leadership scale (VILS). The VILS uses Venn diagrams of sets of overlapping circles to denote different degrees of alignment between a leader's characteristics and behaviours and a group's values and goals. Key advantages of the VILS over other existing multi‐item scales are that it provides a holistic assessment of identity leadership, is short, and can be adapted to address novel research questions that are impractical to address with existing scales (e.g. in diary studies, assessing multiple comparisons of many leaders or groups). Data from three studies (conducted in India, the United States and Germany) provide evidence of the VILS' construct reliability and validity. Results also showcase the instrument's capacity to be adapted to assess variations of identity leadership—for example, by assessing a leader's convergence with descriptive and ideal notions of collective self (i.e. with ‘who we are’ and ‘who we want to be’). We discuss the value of including the VILS in the toolbox that researchers and practitioners can utilize to expand our understanding of identity processes in leadership and group behaviour.

引入并验证身份领导力的单项衡量标准：视觉识别领导力量表（VILS）

在本研究中，我们引入并验证了身份领导力的单项衡量标准——视觉识别领导力量表（VILS）。 VILS 使用一组重叠圆圈的维恩图来表示领导者的特征和行为与团队的价值观和目标之间不同程度的一致性。与其他现有的多项目量表相比，VILS 的主要优势在于，它提供了对身份领导力的整体评估，时间较短，并且可以适应解决现有量表无法解决的新研究问题（例如，在日记研究中，评估许多领导者或团体的多重比较）。来自三项研究（在印度、美国和德国进行）的数据提供了 VILS 结构可靠性和有效性的证据。结果还展示了该工具适应评估身份领导力变化的能力，例如，通过评估领导者与集体自我的描述性和理想概念（即“我们是谁”和“我们想成为谁”）的融合程度。我们讨论了将 VILS 纳入工具箱的价值，研究人员和从业者可以利用该工具箱来扩展我们对领导力和群体行为中的身份过程的理解。
