Smartwatch use intensity and social physique anxiety: the moderating role of neuroticism and conscientiousness.
Article in BMC psychology, 2026. 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
backgroundThe widespread adoption of smartwatch technology has fundamentally transformed how individuals engage with physical activity. However, limited research has examined the psychological implications of intensive smartwatch use during exercise. This study investigated the cross-sectional relationship between smartwatch use intensity and social physique anxiety among adult exercisers in China, and examined whether personality traits moderate this relationship.
methodsA cross-sectional survey was conducted with 486 regular exercisers (mean age = 28.73 years, standard deviation = 7.42; 52.1% female) recruited from fitness centres in Hefei, Anhui Province, China. Participants completed validated measures including the Chinese 7-item Social Physique Anxiety Scale (C-SPAS-7), a purpose-developed Smartwatch Use Intensity Scale (SUIS), and the Big Five Inventory. Common method bias was assessed using Harman’s single-factor test. Hierarchical regression and moderation analyses were conducted using the PROCESS macro.
resultsSmartwatch use intensity was positively associated with social physique anxiety (β = 0.29, p < .001), controlling for demographic and exercise-related covariates. Neuroticism significantly moderated this association (ΔR² = 0.028, p < .001), with the association being stronger among individuals high in neuroticism. Conscientiousness also moderated the association (ΔR² = 0.012, p = .008), with the association being weaker among individuals high in conscientiousness.
conclusionsThese findings highlight the importance of individual differences in understanding the psychological correlates of wearable technology use. Given the cross-sectional design, causality cannot be established; it remains possible that pre-existing anxiety drives more intensive technology use rather than the reverse. Individuals high in neuroticism may be particularly vulnerable to anxiety associated with intensive smartwatch use, while conscientiousness may serve as a protective factor. Although the moderation effect sizes were small (2.8% and 1.2% additional variance), they represent potentially meaningful individual differences that could accumulate over time. These results have implications for personalised fitness technology design and user wellbeing interventions.
