Nursing Dental Coping Belief Scale among Portuguese healthcare professionals (NDCBS-PT): validation and associated factors.
Article in Frontiers in public health, 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
Background: Oral health is a critical yet frequently overlooked component of global public health, with significant implications for overall health and healthcare costs. In countries like Portugal, where public dental coverage is limited, non-dental healthcare professionals are primarily responsible for monitoring oral health. This study aimed to adapt and validate the Nursing Dental Coping Belief Scale for Portuguese healthcare professionals (NDCBS-PT) and identify factors associated with their beliefs to develop effective interventions and ensure equitable care for dependent populations. Methods: This cross-sectional psychometric study followed a five-stage international protocol. Structural validity was tested via confirmatory factor analysis (CFA) using the weighted least squares mean and variance (WLSMV) estimator. Internal consistency and temporal stability were evaluated using ordinal alpha, McDonald's omega total (ωt), and intraclass correlation coefficients (ICC). Multivariable associations were examined using robust linear models to identify factors independently associated with NDCBS-PT scores. Results: A total of 304 healthcare professionals were included (82.6% female; mean age 44.5 years). The correlated four-factor model - internal locus of control (IL), external locus of control (EL), self-efficacy (SE) and oral healthcare beliefs (OHCB) - showed the best relative fit, although fit was marginal (CFI = 0.858). Despite pronounced floor effects, total-score reliability was acceptable to good (ordinal α and ωt = 0.81). The institutional sector was the most consistent independent determinant of global scores ( Conclusion: The NDCBS-PT demonstrated sufficient reliability and preliminary structural support for the four-factor model among Portuguese healthcare professionals, though requiring further refinement. Caregivers' beliefs appear to be influenced by organizational settings and professional backgrounds. Oral-health training was linked to better self-efficacy and merits prospective testing.
