Allies are members of an ingroup who work toward fairness for people in an outgroup. Ally behaviors include calling out discrimination and fighting for inclusion of outgroup members, and it includes public and private behaviors. As such, White allies can be an important means of reducing racism against people of color. There are few means of assessing and quantifying allyship in ingroup members, and as such, there is a need for methods for assessing allyship that can be used to better understand characteristics of allies and determine if interventions designed to reduce prejudice can improve allyship. To that end we describe an innovative scenario-based measurement technique to quantify interpersonal allyship, with White students as ingroup members (N = 987) and Black students as outgroup members (N = 61). Measurement of allyship is conducted based on participant responses to hypothetical racially-sensitive scenarios where microaggressions are occurring or likely to occur. Items were developed based focus group input, and rated by diversity experts for relevance. The factor structure of allyship items was examined by exploratory and confirmatory factor analyses. The final 10-item Interpersonal Racial Allyship Scale (IRAS) was negatively correlated to 3 measures of racist attitudes and 1 measure of microaggressive behaviors, and it was positively correlated to 2 measures of outgroup liking. It also predicted making racially supportive statements in a laboratory task. We report on characteristics of allies, noting that allied behaviors are correlated with less prejudice, stronger positive feelings toward outgroup members, and a greater likelihood of having other marginalized identities. Implications of findings and applications of the scale are discussed.

盟友是小组成员，致力于为小组成员中的人们保持公平。盟友的行为包括呼吁歧视和为包容外来成员而斗争，其中包括公共和私人行为。因此，白人盟友可以成为减少针对有色人种的种族主义的重要手段。缺乏评估和量化团内成员同盟关系的方法，因此，需要一种评估同盟关系的方法，以更好地了解盟友的特征并确定旨在减少偏见的干预措施是否可以改善同盟关系。为此，我们描述了一种基于情景的创新测量技术来量化人际交往，白人学生为小组成员（N  = 987），黑人学生为小组成员（N = 987）。ñ = 61）。对同盟关系的衡量是基于参与者对假设的种族敏感情景正在发生或可能发生的情况的反应而进行的。项目是根据焦点小组的意见而制定的，并由多样性专家对其相关性进行了评级。通过探索性和确认性因素分析来检查同盟项目的因素结构。最终的10项人际种族同盟关系量表（IRAS）与3种种族主义态度和1种对小人侵略行为的衡量指标呈负相关，与2种对外来群体的喜好程度呈正相关。它还预测在实验室任务中做出种族支持声明。我们报告了同盟国的特征，并指出同盟国的行为与偏见减少，对外联成员的积极情绪增强相关，以及具有其他边缘化身份的可能性更大。讨论了调查结果的含义和该量表的应用。
