1 · What the graph read from it

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.

2 · The registry

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 7-item Short Warwick-Edinburgh Mental Well-Being Scale (SWEMWBS) is widely used for measuring mental well-being due to its strong psychometric properties. However, its suitability for adolescents, particularly across gender and age groups, has not been established. The aim of the study was to assess the psychometric properties, factor structure, and measurement invariance of the SWEMWBS in Finnish youth.

methodsThe data from the 2017 School Health Promotion Survey included 132,828 young people (aged 13 to 20; 48.0% cis-female, 46.5% cis-male) from Finnish lower and upper secondary schools. The study employed exploratory factor analysis (EFA), confirmatory factor analysis (CFA), McDonald's omega (ω), and measurement invariance.

resultsA single-factor model with good internal consistency (ω = 0.962) was confirmed via CFA, with minor residual correlations included in the model. Full scalar invariance was established across age, perceived health, chronic illness, loneliness, relationship status, and having at least one friend. The results indicate that the scale is suitable for detecting true differences in mental well-being across these groups. However, scalar invariance was only partial for gender and mental ill-health, suggesting some variability in the measurement properties of the SWEMWBS.

conclusionsThe SWEMWBS is sufficiently unidimensional and suitable for measuring mental well-being among Finnish adolescents. The scale is appropriate for population-level monitoring, as well as in intervention studies targeting the mental well-being in youth. However, comparing scores with the adult population or between specific groups (e.g., those with or without mental health conditions) requires caution.
