Servant leadership has been gaining attention from all types of organizations, whether it be business organizations or public schools. With the increase of studies on the servanthood characteristics of organizational leaders, various scales of servant leadership were used to examine servant leadership behaviors, perceptions, and attitudes in different organizations. In line with the increasing interest on servant leadership, the purpose of the study was aimed at characterizing the Servant Leadership (SL) scale psychometrically through Confirmatory Factor Analysis (CFA) and Rasch analysis. The related data were collected from 461 teachers across several countries. The one-factor structure of the SL was confirmed in CFA along with the Rasch Rating Scale model, with the analyses of rating scale diagnosis, item fit assessment, reliability, unidimensionality, local independence, and differential item functioning (DIF). High person separation and reliability statistics supported the consistency of the SL scores. Only one item (Item 7) did not fit the Rasch model, and another item (Item 1) showed DIF to be in favor of females. Overall CFA and the Rasch models provided enough evidence for the seven-item SL scale.
服务型领导已经引起了各种类型组织的关注，无论是商业组织还是公立学校。随着对组织领导者服务特质的研究增多，各种服务型领导量表被用于检验不同组织中的服务型领导行为、认知和态度。鉴于对服务型领导的兴趣不断增加，本研究旨在通过验证性因素分析（CFA）和罗夏分析对服务型领导量表（SL）进行心理计量学特征描述。相关数据是从来自多个国家的 461 名教师那里收集的。在 CFA 中，SL 的单因素结构与罗夏评分量表模型一致，分析包括评分量表诊断、项目拟合评估、信度、单维性、局部独立性和项目区分度（DIF）。高的个体分离和可靠性统计支持了 SL 分数的一致性。只有一个项目（项目 7）不符合罗夏模型，另一个项目（项目 1）显示出对女性有利的 DIF。总体而言，CFA 和罗夏模型为七项 SL 量表提供了足够的证据。
