Sense of Coherence: factorial structure and association with oral health - a study of Norwegian adults.
Article in Acta odontologica Scandinavica, 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
objectiveAssess the construct validity of Sense of Coherence (SOC) by testing a one- and a three-factor structure and associations with oral health indicators.
methodIn all, 9000 adults were randomly selected from a national population panel of 83,000 and 1,557 completed telephone interviews. SOC was measured using the 13-item Norwegian version of the original 29-item Orientation to Life questionnaire. Oral health was assessed as oral impacts on daily performances (OIDP), periodontal symptoms and attitudes towards oral health. Descriptive statistics and multivariable logistic regression analyses were conducted using Statistical Package for the Social Sciences (SPSS). Confirmatory factor analysis (CFA) was performed using the Lavaan package in R.
resultsConfirmatory factor analysis provided satisfactory fit to a modified one-factor model; comparative fit index (CFI) = 0.940, root mean squared error of approximation (RMSEA) = 0.062, Tucker-Lewis index (TLI) = 0.925. Factor loadings ranged from 0.360 to 0.798. Metric invariance was obtained across sexes. Adults having strong SOC were less likely to report oral impacts and periodontal symptoms, and more likely to report positive oral attitudes.
conclusionThis study demonstrated construct validity of the Norwegian version of SOC 13 and that, in the presence of socio-demographic factors, SOC is an important contributor to oral health outcomes. SOC should be considered in oral health educational and promotional interventions among Norwegian adults.
