Psychometric Analysis of the Flow Short Scale translated to Finnish

We report a psychometric scale validation study on a Finnish translation of the Flow Short Scale (FSS). Data from 200 Finnish speaking participants were collected via the Prolific Academic platform. To analyse the scale's factorial structure, we performed Mokken scale analysis, Parallel Analysis, Very Simple Structures analysis and a standard Confirmatory Factor Analysis. Then, we evaluated the correlations between FSS and two other flow scales, the Flow State Scale and Flow Core Scale. Finally, we evaluated the FSS's ability to distinguish flow-inducing experiences from boring (non-flow-inducing) experiences. Collectively the results showed that an 8-item, two-factor version of the scale was a justified instrument with good psychometric properties.
