"Developing and Testing the Team Flow Monitor (TFM)" by van-den-hout, Josette Gevers, orin-davis, and Mathieu Weggeman, published in Cogent Psychology (6(1)) in 2019, reports the development and psychometric validation of the Team Flow Monitor — a self-report measurement instrument for team-level team flow tested across 110 teams. It is the empirical companion to conceptualization-of-team-flow-2018 and the methodological centerpiece of team-flow-van-den-hout-2019.
The measurement gap it fills
Individual flow-state has well-established measurement instruments: csikszentmihalyi's experience-sampling-method for ecologically valid in-context measurement, and the Flow State Scale (FSS) and Dispositional Flow Scale (DFS) for retrospective and dispositional measurement. But these instruments all operate at the individual level. Prior to the TFM, there was no validated instrument for measuring flow at the team level — researchers either aggregated individual flow scores (which the conceptualization-of-team-flow-2018 framework argues misses genuinely collective phenomena) or relied on qualitative assessment. The TFM fills this gap.
Psychometric findings

The Josette Gevers co-authorship is notable: Gevers is an organizational psychologist at Eindhoven University of Technology specializing in team temporal dynamics and goal pursuit, contributing methodological expertise in team-level measurement design.
Position in the measurement lineage
The TFM is to team flow what the ESM is to individual flow-state: the empirical instrument that moves the construct from descriptive theory to measurable variable. This matters for the flow KB because a significant portion of the KB's evidential weight depends on distinguishing what has been empirically measured from what has been theorized. sawyer's ten-conditions-for-group-flow were derived from qualitative observation; van-den-hout's conceptualization-of-team-flow-2018 was theoretical operationalization; this paper is the quantitative measurement validation.
A 2024 longitudinal intervention study subsequently used the TFM as the primary instrument in a self-reflection protocol applied across 15 teams in 5 organizations, demonstrating that teams could use TFM-guided measurement to improve their team flow conditions over time — the first intervention-level application of team flow measurement.
Significance
The TFM is the instrument that makes group-flow research in organizational settings fully rigorous in the psychometric sense. Without it, team flow remains an intellectually compelling construct without the measurement foundation needed for organizational research at scale. With it, the conceptualization-of-team-flow-2018 framework becomes testable in any organizational context with access to team self-report data. For practitioners, the TFM is also the tool that makes team flow diagnoses and interventions possible rather than merely theoretical.
