The aim of the present study was to adapt the LONG Dispositional Flow Scale–General (DFS-2 General) to Brazilian Portuguese and assess evidence of the instrument’s validity. The DFS-2 General is an instrument for measuring flow in general contexts. The study was divided into two phases. The first involved translation and cultural adaptation of the DFS-2. The second entailed conducting an empirical study to assess evidence of construct and convergent validity, as well as internal consistency. The sample consisted of 310 adults (77.4% female) between the ages of 18 and 63 (M = 30.7 SD = 9.2). Based on the parameters of Jackson et al. (2010), we performed confirmatory factor analysis of two models: one with nine first-order factors, and the other with one second-order Flow factor and the same nine first-order factors. A new six-factor model, also with one second-order Flow factor, was proposed. The DFS-2 General presented adequate psychometric properties, indicating its suitability for assessing flow at work within the Brazilian context. The results revealed significant positive correlations between flow and both satisfaction with life and positive affects, as well as a significant negative correlation between flow and negative affects. Significant negative correlations between flow and stress were also found.
