Despite there being an increasing number of applied flow studies across scientific disciplines, there exists no consistent or broadly applicable intervention to promote flow experiences. This study provides a detailed account of a new educational flow training program developed following recent advancements in the flow literature that have provided a more parsimonious understanding of flow experiences and antecedents. Guided by CONSORT guidelines for feasibility trials, we conducted a single-group, non-randomized feasibility trial of an educational flow training program (N =26). We assessed participant retention, perceptions about and experiences of the program, perceptions about the flow education training, and preliminary assessments of flow as an outcome. Results broadly supported program feasibility, and participants reported positive experiences in, and perceptions of, program components. In terms of preliminary efficacy, we observed evidence of noteworthy change pre-to-post-program in flow (d= 0.84), performance (d= 0.81), competence (d= 0.96), well-being (d= 0.68), intrinsic motivation (d= 0.47), interest (d= 0.72), choice (d= 0.38), stress (d= -1.08), ability to handle stress (d= 0.74), and anxiety (d= − 0.86). These results provide preliminary evidence that it may be possible to ‘train’ flow in line with recent perspectives on a core three-dimensional flow experience (and antecedents). The study has developed a research foundation for flow intervention “curriculum” and quality standards, and for measuring results. It offers a foundation for the implementation of a larger-scale program.Supplementary InformationThe online version contains supplementary material available at 10.1007/s41042-023-00098-2.
