Psychosocial moderators of the effect of lifestyle interventions in primary prevention of cardiovascular disease: a scoping review.
Article in BMC public health, 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
backgroundLifestyle modification plays a key role in prevention of cardiovascular disease (CVD), but often fails due to non-adherence to lifestyle recommendations. Previous research has highlighted the importance of psychosocial factors in non-adherence, though focused on secondary rather than primary prevention. The aim of this scoping review was to provide an overview of the moderating role of psychosocial factors on the effect of lifestyle interventions in primary CVD prevention.
methodsA literature search of scientific databases was performed to identify studies published in peer-reviewed journals, that evaluated lifestyle interventions in primary prevention in adult populations (18 years and older), with a composite CVD risk score or a CVD risk factor (diet, physical activity, smoking or alcohol) as outcome, and assessed the moderating effect of a psychosocial factor.
resultsThirty-five studies published between 2000 and 2025 were included in this review. Most were randomized controlled trials (RCT), included middle-aged participants, and investigated samples in which women were in majority. The outcomes differed, with fourteen studies reporting on physical activity, eleven on diet, six on body weight, two on smoking and one on alcohol. One study used a CVD risk score as the outcome. The studies included a broad array of psychological factors that were grouped into five categories: self-efficacy or motivation (n = 11), social support or relationship quality (n = 8), mental health (n = 6), personality or emotions (n = 6), and cognitive factors (n = 4). Sixteen (44%) of the studies did not use validated instruments in the assessment of the psychosocial factor.
conclusionsThis review highlights the potential role of psychosocial factors on the effectiveness of lifestyle interventions. However, our ability to draw detailed conclusions or identify any general trends were limited by the heterogeneity amongst the studies in terms of study design, assessment of outcomes and moderators, and populations. Still, we identified a lack of RCTs (1) with long follow-up time, (2) with sufficient sample size, (3) using validated instruments to assess the psychosocial moderator, and (4) using interaction analyses to assess moderating effect.
