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

purposeThe Mind Excessively Wandering Scale (MEWS) assesses excessive mind-wandering. This study evaluated the psychometric properties of the Persian 12-item MEWS (MEWS-12) among Iranian adolescents, focusing on factor structure, internal consistency, associations with external measures, known-groups validity, and gender measurement invariance.

methodIn this cross-sectional study, 506 adolescents aged 12-18 years completed the MEWS and measures of rumination, attentional control, mindfulness, depressive and anxiety symptoms, and positive and negative affect. All 15 original MEWS items were administered, with the developer-recommended 12-item version designated for primary analyses. The sample was randomly divided, with stratification by gender, into independent exploratory factor analysis (EFA; n = 254) and confirmatory factor analysis (CFA; n = 252) subsamples. FINDING: Parallel analysis favored a two-factor EFA solution accounting for 54% of the variance, with a factor correlation of 0.73. In CFA, the correlated two-factor model showed better fit than the unidimensional model, χ

conclusionThe findings provide preliminary evidence regarding the psychometric properties of the Persian MEWS-12 among Iranian adolescents. The two-factor representation should be interpreted cautiously given the substantial factor overlap. Further replication in independent samples and evaluation in longitudinal and clinically characterized studies are warranted.
