Good stress is not the opposite of bad stress

Most stress research asks how pressure harms us, yet challenging situations can also feel energising, meaningful and even enjoyable. That positive experience of challenge is called eustress, and if it could be reliably defined and measured, workplaces, schools and practitioners could try to foster it deliberately. The difficulty is establishing which features actually make up eustress. Is it a single quality, a bundle of processes such as expecting success and feeling fulfilled, or something that changes entirely from one situation to the next? This study set out to map those features across a wide range of real-life challenges.

The researchers ran a pre-registered study with 251 UK adults using the Situated Assessment Method. Each participant evaluated their eustress across 20 real-life challenging situations, such as giving a public speech in front of a large audience. They also rated nine processes proposed to drive eustress, drawn from the Comprehensive Hierarchical construct of Eustress, including successful outcomes, fulfilment and positive affect. Finally, in a multilevel design, participants completed general trait questionnaires measuring eustress, distress and stress mindset, which let the team compare situation-specific judgments with broader dispositions.

People differed reliably in how much eustress they reported on average across situations, so it behaves partly like a stable trait, but situations themselves also mattered substantially, and the interaction between person and situation was large: the same individual could find one challenge invigorating and another draining. The nine candidate processes correlated strongly with eustress, explaining a median 83% of the variance in individual-level regressions, which supports the construct's validity. Averaged situated eustress correlated with trait eustress and with stress mindset, but was unrelated to trait distress. Factor analyses revealed a dominant general factor of eustress alongside modest multidimensional structure.

The findings align with existing theories of stress while sharpening them: eustress is not simply the absence of distress, since the two were unrelated at the trait level, and it is neither purely situational nor purely dispositional but both at once. The work also contrasts different ways of measuring eustress, situated versus trait, suggesting each captures something distinct. What remains open is whether the descriptive profiles here can guide practice: the authors propose personalised, context-sensitive interventions to foster eustress, but this study measured the construct rather than manipulated it, so whether cultivating processes like fulfilment actually raises eustress is untested.

This is a reason to think the good kind of stress is real, identifiable and heavily shaped by the specific challenge in front of you rather than being a fixed personality feature. Feeling flat in one demanding situation does not mean you lack the capacity for eustress elsewhere, because the person-by-situation interaction was large. It also suggests that thriving under pressure and suffering under pressure are separate dials, not opposite ends of one scale. That is informational rather than a technique: the study described what eustress looks like across situations, not how to switch it on.
