Bidirectional week-to-week relationships between weekly psychological stress across multiple life domains and engagement with an exercise intervention: secondary analysis of data from a randomized trial.
Trial report in Annals of behavioral medicine : a publication of the Society of Behavioral Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEngaging in physical activity can reduce the risk of multiple morbidities and premature mortality. Psychological stress can hinder the development and maintenance of physical activity behaviors. There is a dearth of research on how these two processes interact. PURPOSE: The purpose of this study was to identify the week-to-week bidirectional associations between weekly psychological stress across multiple domains (e.g. social, economic) and adherence to a six-week mHealth exercise program among a previously inactive sample.
methodsThe secondary analyses reported in this study examine data derived from adults randomized to one of three mobile application(s)-based exercise arms embedded within the COPE trial (N = 251). The interventions delivered to participants in each arm involved six weeks of at-home exercise requiring no additional equipment. Relationships between psychological stress (as measured by a modified version of the Chronic Burden Scale) and engagement with the commercially available exercise apps were explored using a random intercept cross-lagged panel model (RI-CLPM). This model simultaneously assessed the longitudinal and bidirectional associations between psychological stress and exercise engagement and vice versa.
resultsBoth psychological stress and engagement with the exercise interventions demonstrated significant positive autoregressive effects across successive weeks. However, the cross-lagged associations between stress and engagement with the exercise intervention were not significant.
conclusionsWhile the cross-lagged effects were non-significant, there was high variability between individuals. Future studies should use larger samples and methods that would allow an examination of an individual's relationship between psychological stress and exercise engagement.
