Individual work performance can be defined as individual behaviour capable of generating value and a competitive advantage for the organization. Furthermore, this construct is linked to other fundamental variables that constitute worker well-being, such as job satisfaction and engagement. Although important, a complete measure of individual work performance is still lacking in the Italian context. The objective of this work is to validate the Individual Work Performance Questionnaire (IWPQ) within the Italian organisational context. The IWPQ is a multi-dimensional construct consisting of task performance, contextual performance, and counterproductive work behavior. To investigate the psychometric properties of the Italian IWPQ, 1053 participants were enrolled, whose ages ranged between 19 and 69 years. EFA, CFA, and MCFA analyses were performed to test the structural factors of the IWPQ. The results supported the validity of the IWPQ in the Italian context; the final structure consisted of 17 items. Multigroup confirmatory factor analysis showed that the factor solution was invariant across both gender and occupational categories and found evidence of metric, uniqueness, scalar, and structural invariance. Convergent validity was also tested and demonstrated. Adequate studies on the importance of individual performance can be used to better understand and distinguish the different components affecting performance.
个体工作绩效可定义为能够为组织创造价值和竞争优势的个体行为。此外，这一概念与构成员工福祉的其他基本变量相关联，如工作满意度和敬业度。尽管个体工作绩效很重要，但在意大利背景下仍缺乏对其全面的衡量方法。本研究的目的是在意大利组织背景下验证个体工作绩效问卷（IWPQ）。IWPQ是一个多维概念，由任务绩效、情境绩效和反生产工作行为组成。为了研究意大利IWPQ的心理测量特性，招募了1053名参与者，年龄在19岁至69岁之间。进行了探索性因素分析（EFA）、验证性因素分析（CFA）和多组验证性因素分析（MCFA）以检验IWPQ的结构因素。结果支持了IWPQ在意大利背景下的有效性；最终结构由17个项目组成。多组验证性因素分析表明，因素解决方案在性别和职业类别上都是不变的，并发现了度量、独特性、标量和结构不变性的证据。还对收敛效度进行了测试和验证。关于个体绩效重要性的充分研究可用于更好地理解和区分影响绩效的不同组成部分。
