For decades, scholars have studied leader-member exchange (LMX) relationships to understand and explain the effects of leadership on follower attitudes and performance outcomes within work settings. One available instrument to measure these aspects is the LMX-7 scale. This measurement has been widely used in empirical studies, but its psychometric properties have been poorly explored. The aim of this study was to test the psychometric characteristics (content, structural and construct validity, and reliability) of the Italian version of the LMX-7 scale and to support its cultural adaptation. We used a cross-sectional multi-center design. The forward-backward translation process was used to develop the Italian version of the scale. The scale was administered through an online survey to 837 nurses and nurse managers working in different settings. The factorial structure was tested using both exploratory and confirmatory factor analyses (EFA and CFA), and reliability was evaluated using Cronbach's alpha. For the construct validity, we used hypothesis testing and differentiation by known groups. The Italian version of the LMX-7 scale presented one dimension. All the psychometric tests performed confirmed its validity and suggested its usefulness for future research.
几十年来，学者们一直在研究领导成员交换（LMX）关系，以理解和解释领导力对工作环境中下属态度和绩效结果的影响。一种可用于衡量这些方面的工具是LMX-7量表。该测量方法已在实证研究中广泛使用，但其心理测量特性却鲜有探讨。本研究的目的是测试意大利语版LMX-7量表的心理测量特征（内容、结构和构想效度以及信度），并支持其文化适应性。我们采用了横断面多中心设计。通过前后翻译过程来开发该量表的意大利语版本。该量表通过在线调查的方式施测于837名在不同工作环境中工作的护士和护士长。使用探索性和验证性因素分析（EFA和CFA）来测试因子结构，并使用克朗巴哈系数来评估信度。对于构想效度，我们使用假设检验和已知组别的区分。意大利语版LMX-7量表呈现出一个维度。所进行的所有心理测量测试均证实了其效度，并表明其对未来研究有用。
