Internal Validity and Reliability of the GAD-7 Test in Latin America.
Article in Chronic stress (Thousand Oaks, Calif.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Generalized anxiety has significantly increased in the general population during and after the COVID-19 pandemic, highlighting the need for rapid screening tools. In this context, the present study analyzed the psychometric properties and internal consistency of the Generalized Anxiety Disorder Scale (GAD-7) in healthcare workers and the general population in Latin America. A cross-sectional e-health study was conducted, surveying 11,279 Latin Americans online using snowball sampling. The sample included healthcare professionals, hospital populations, community members from various occupations, and university students from six countries (Argentina, Bolivia, Ecuador, Chile, Colombia, and Peru). Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed separately for each country. Additionally, the instrument's internal consistency was evaluated by calculating McDonald's W index and item-total correlations based on the final items. The EFA revealed a unidimensional structure comprising the seven items of the instrument, which explained between 62.8% and 66.1% of the variance (KMO = between .900 and .910; p < .000). The CFA confirmed adequate fit indices for each country. The omega index ranged from 0.85 (Peru: CI = 0.800-0.884) to 0.95 (Argentina-Bolivia: CI = 0.901-0.985), and item-total correlations were high, ranging from .642 to .869, demonstrating the instrument's reliability. In conclusion, the findings of this study indicate that the GAD-7 is a valid and reliable instrument for assessing generalized anxiety symptoms in the Latin American population.
