Fatigue at Work: Scale Validation with Airline Pilots

ABSTRACT In the organizational context, the study of occupational stress encompasses constructs of fatigue at work. Within the air transportation sector, fatigue at work is a potential issue influencing both safety and occupational stress. The objective of the present study was to perform a convergent-discriminant validity analysis of the Feeling of Fatigue scale in the area of Administration. Data from an observational cross-sectional study involving a sample of 1,066 airline pilots were analyzed using quantitative modeling. Confirmatory factor analysis with the structural equations model was performed to determine the validity of a Portuguese version of the Feeling of Fatigue scale in the organizational context of civil aviation. This study fills a gap in the literature on occupational stress in Administration, highlighting the relevance of research on fatigue at work. The results confirmed the validity of a Portuguese version of a mature scale for subjective assessment of fatigue in Administration, thereby contributing to fatigue management in organizational settings.摘要：在组织情境中，职业应激（occupational stress）的研究涵盖工作疲劳这一构念。在航空运输领域，工作疲劳是同时影响安全与职业应激的潜在问题。本研究旨在对行政管理领域的工作疲劳感量表（Feeling of Fatigue scale）开展会聚区分效度（convergent-discriminant validity）分析。本研究针对由1066名航空公司飞行员组成的样本开展观察性横断面研究（observational cross-sectional study），采用定量建模方法对采集的数据进行分析；并通过基于结构方程模型（structural equations model）的验证性因子分析（Confirmatory factor analysis），检验民航组织情境下葡萄牙语版工作疲劳感量表的效度。本研究填补了行政管理领域职业应激相关研究的空白，凸显了工作疲劳研究的现实意义。研究结果证实了行政管理领域疲劳主观评估成熟量表的葡萄牙语版本具有良好效度，可为组织情境下的疲劳管理提供实践支撑。
