Need satisfaction and frustration scale (NSFS): adaptation and validation for Brazilian gig work context

Purpose This study aims to adapt and validate the need satisfaction and frustration scale (NSFS) for the Brazilian gig work context and investigate the distinctiveness of the constructs of basic needs satisfaction and frustration among Brazilian gig workers. Design/methodology/approach Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted on a sample of 351 Brazilian gig workers. Findings Results from EFA supported a three-factor structure, while results from CFA psychometrically supported a six-factor correlated model. The items that constitute the NSFS presented good discriminant validity (heterotrait-monotrait ratio) and internal consistency (Cronbach’s alpha and McDonald’s omega coefficients). Results regarding criterion validity partially support previous empirical evidence that considers needs satisfaction and frustration independent in relation to well-being and ill-being while reinforcing the need for further investigations. The Brazilian version of the NSFS is shown to be an instrument with robust psychometric qualities to assess workers’ perception of basic needs satisfaction and frustration in Brazilian gig work context. Originality/value This study broadens the scope of research on basic psychological needs by introducing a valid and reliable instrument to assess workers’ perceptions of needs satisfaction and frustration in the Brazilian gig work context, a population that has been neglected in self-determination theory research.
