Psychometric Properties of the General Anxiety Disorders-7 Scale Using Categorical Data Methods: A Study in a Sample of University Attending Ethiopian Young Adults.
Article in Neuropsychiatric disease and treatment, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
backgroundFew studies have investigated the psychometric validation of the General Anxiety Disorders-7 Scale (GAD-7) using appropriate data assumptions. This study examined the reliability, factorial validity, divergent validity, and item analysis of the GAD-7 using categorical data methods in a sample of Ethiopian young adults.
methodsA sample of 270 students in the age group (18-20 years) was recruited during February-May of 2017 in this cross-sectional study using simple random sampling. The participants completed a tool for socio-demographic details, the GAD-7, and the Perceived Stress Scale-10 (PSS-10).
resultsThe cumulative variance rule (> 40%), the scree test, Kaiser's criteria (Eigenvalues > 1), and the parallel analysis found a 1-factor model for the GAD-7 (factor loadings, 0.38 to 0.63). Fit indices suggested a 1-factor model: the tests applied included the weighted root mean square residual (0.030), comparative fit index (1.000), the goodness of fit index (1.00), root mean square error of approximation (0.037) and the non-normed fit index (1.00). McDonald's Omega (0.772) implied that the scores had adequate internal consistency. Divergent validity was supported by significant but weak correlations that were found between the GAD-7 and PSS-10 scores (r = 0.11 to 0.25,
conclusionThe psychometric validity of the GAD-7 in Ethiopian university attending young adults was supported by the categorical data method.
