Translation, cultural adaptation, and validation of the Geriatric Depression Scale - Short Form into Bengali among elderly people in Bangladesh.

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
Depression is a major health concern among the elderly, affecting their quality of life. The Geriatric Depression Scale - Short Form (GDS-15) is commonly used to screen for depression in older adults. This study aimed to translate, culturally adapt, and validate the GDS-15 into Bengali for use among elderly people in Bangladesh. The GDS-15 was translated into Bengali, followed by cultural adaptation. A cross-sectional study was conducted with 100 elderly participants aged 60 years, and above in Chittagong Medical College Hospital. Psychometric validation was performed using reliability testing, chi-square analysis, ANOVA, and principal component analysis (PCA). The Bengali version of the GDS-15 demonstrated strong construct validity, with significant correlations between the original and translated versions of the items (r = 0.9788, p < 0.001). However, reliability analysis showed a low Cronbach's alpha (0.4753), indicating suboptimal internal consistency. The PCA revealed multiple components, suggesting the multidimensionality of the scale in this population. The Bengali GDS-15 showed low internal consistency which warrants the need for further cultural refinement and psychometric validation before routine use among the population. However, the Bengali GDS-15 has the potential to serve as a useful screening tool for geriatric depression in Bangladesh with further improvements.
