The structural attributes and correlates of items have an effect on their composite scores and exploring them strengthens the content validity of a measure adapted to another context. The objective of this study was to evaluate the item properties of a measure of psychosocial work factors (PWFs). Data were collected through a web platform from 188 Peruvian working adults (men = 101, 50.5%) holding various professions and jobs. The instrument was the Psychosocial Processes at Work Scale (PROPSIT), adapted for the Peruvian context. The distributional characteristics, the efficiency of its response options and its correlates with engagement, occupational self-efficacy, general stress and psychological distress (explored with a coefficient of maximum information and another of monotonic association) were analyzed. It was found that the items were asymmetrically distributed, without statistical normality and with a response tendency at low (for psychosocial risk factors (PSRFs)) and medium (favorable psychosocial resources) levels. The number of efficient response options was lower (approximately five options) than the original structure (seven options). The monotonic associations with gender and age were essentially zero and theoretically converged with the external constructs, except for some items related to job demands. The contributions of the results to the content validity of the PROPSIT and the orientation of working hypotheses about PROPSIT item constructs and measures of work effects are discussed.
项目的结构属性及其相关性会影响其综合得分，而对其进行探索则可以增强在另一种情境下适应的测量工具的内容有效性。本研究旨在评估一个社会心理工作因素（PWFs）测量工具的项目属性。数据通过网络平台收集了来自 188 名秘鲁成年工作者（男性=101，50.5%），他们从事各种职业和工作。研究工具是针对秘鲁情况改编的工作中的心理社会过程量表（PROPSIT）。分析了分布特征、其反应选项的效率以及与参与度、职业自我效能感、一般压力和心理困扰（通过最大信息系数和单调关联系数进行探索）的相关性。结果发现，项目呈非对称分布，没有统计正态性，且反应倾向处于低（社会心理危险因素（PSRFs））和中（有利的社会心理资源）水平。有效的反应选项数量较少（大约五个选项），而不是原始结构（七个选项）。与性别和年龄的单调关联基本上为零，并且与外部结构理论上是一致的，除了与工作需求相关的一些项目。本文讨论了结果对 PROPSIT 内容有效性的贡献以及关于 PROPSIT 项目结构和工作效果测量的工作假设的方向。
