Validação da Versão Reduzida do Inventário de Felicidade no Trabalho.

Happiness is a socially constructed psychological state, where being happy is feeling positive emotions in the here and now, but with long-term meaning and purpose. When considering the centrality of work in people's lives, it is paramount to understand the valued aspects of building happiness at work. This study aimed to validate the short version of the Happiness at Work Inventory (HWI) using a sample of 814 Brazilian participants. For the short version, the sample was randomly divided into two subsamples. The first was used for exploratory factor analysis to test the original factor structure, resulting in a unidimensional model with 25 items. The second subsample was used for the confirmatory factor analysis. The results indicate that the short version of the HWI has good psychometric properties and is viable for future research with workers. [ABSTRACT FROM AUTHOR]
