Summary
AI-generated from the abstractA short adapted version of the Flow State Scale (FSS-2) for Brazilian-Portuguese and general activities, the FSS-BR-S, was developed and tested with 396 Brazilian participants. The scale, consisting of nine items, showed good internal consistency and a good fit to the data in confirmatory factor analysis. Item quality analysis indicated that its difficulty and differentiating parameters are adequate for estimating overall flow state. The test information curve suggests the short version is useful for estimating flow states. The FSS-BR-S demonstrated sufficient validity for use with Brazilians.

Abstract
"Flow experience" is a term used to describe the state of being fully immersed in what you are doing. The Flow State Scale (FSS-2) was developed to assess how people feel when they are in the flow state while participating in certain sports activities. The goal of this study was to obtain a short adapted version of the FSS-2 for the Brazilian-Portuguese language and for general activities (FSS-BR-S). To do this, we translated it both ways (forwards and backwards) and verified that the translation was accurate. Methods: After getting answers from 396 Brazilian participants, we performed (1) the construct validity of the FSS-BR-S and (2) the psychometric item quality analysis. The confirmatory factorial analysis shows that a FSS-BR-S factorial model is the best fit for the data (χ2 = 44.36, p = .023, df = 27, χ2/df = 1.64, CFI = 0.99, TLI = 0.98, and RMSEA = 0.04). Reliability tests done in this structure show that the FSS-BR-S (which only has nine items) has good internal consistency. The item quality analysis reveals that its difficulty and differentiating parameters are good for estimating the overall flow state. The test information curve for the short version demonstrates that it is very useful for estimating the flow states of each disposition. Discussion and Conclusions: Based on these findings, we can conclude that the FSS-BR-S has demonstrated sufficient validity to be used with Brazilians.
