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.

RESUMO: Esta revisão integrativa sintetiza dados qualitativos e quantitativos convergentes sobre a pesquisa em psicologia sistêmica na América Latina, em populações sem morbidade diagnosticada. Os critérios de eligibilidade seguiram os protocolos PRISMA e PICO. A qualidade dos estudos foi avaliada com o CASP, e o método de síntese foi a triangulação de métodos e dados. Como resultados, a partir da análise de conteúdo dos artigos por meio da nuvem de palavras, foi possível contrastar palavras-chave com categorias emergentes e desenvolver uma meta-síntese, incluindo um meta-modelo da pesquisa em psicologia sistêmica. A busca restringiu-se às bases Pepsic e Web of Science, com foco estreito no tema. Como o tema é inerentemente interdisciplinar, estudos potencialmente relevantes podem não ter sido incluídos.

ABSTRACT: This integrative review synthesizes convergent qualitative and quantitative data about the research on systemic psychology in Latin America, in populations without diagnosed morbidity. Eligibility criteria followed PRISMA and PICO protocols. The quality of studies was evaluated with CASP, and the synthesis method was the triangulation of methods and data. With the results from the article content analysis by means of word clouds, it was possible to contrast keywords with emerging categories and to develop a meta-synthesis, including a meta-model of the research on systemic psychology. The search was restricted to Pepsic and Web of Science databases, with a narrow focus on the theme. As the theme is inherently interdisciplinary, potential relevant studies might not have been included.
