Psychometric validation, factor structure, and measurement invariance of the Arabic brief existential loneliness scale.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Existential loneliness signifies a profound feeling of fundamental separation from others and the world, increasingly acknowledged in the scholarly literature. The Arabic psychological literature lacks the necessary instruments to assess this construct. Methods: The objective of the current study was to develop an Arabic version of the Brief Scale of Existential Loneliness (BSEL). Psychometric validation included internal consistency, test-retest reliability, and validity. The factor structure of the scale was assessed using exploratory factor analysis and confirmatory factor analysis with 420 participants (aged 18-82 years; M = 35.7, SD = 15.3), followed by assessing measurement invariance across gender and age groups. Results: The results showed excellent internal consistency reliability (alpha and omega) and adequate stability. BSEL scores had a positive correlation with depression and existential isolation and a negative correlation with happiness, thus indicating convergent-divergent validity of the scale. The BSEL score showed a negative correlation to age. A unidimensional factor structure was supported. Strict measurement invariance was established across genders, whereas scalar invariance was supported across age groups. Discussion: The results suggest that the Arabic version of the BSEL is a promising and user-friendly tool for assessing existential loneliness among native Arabic speakers.
