Validation Study of the Turkish Version of the Post-Traumatic-Embitterment-Disorder 21-Item Scale.

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
The objective of this manuscript was to adapt the PTED-21 Scale into Turkish and to evaluate its psychometric properties, including validity and reliability. Additionally, the prevalence and levels of embitterment among the participants were assessed. This cross-sectional methodological study included 575 participants. Following a rigorous forward-backward translation process, the PTED-21 was adapted into Turkish. Reliability was assessed using Cronbach's alpha and split-half reliability coefficients. To evaluate construct validity and identify the factor structure, exploratory factor analysis (EFA) was performed using principal component analysis with varimax rotation. Reliability analysis yielded a Cronbach's alpha of 0.960 and a Spearman-Brown coefficient of 0.961. The Kaiser-Meyer-Olkin value was 0.958, and Bartlett's test of sphericity was statistically significant (p < 0.001). Factor analysis revealed that the Turkish PTED-21 consists of a three-factor structure, explaining 67.49% of the total variance. The Turkish version of the PTED-21 is a valid and reliable instrument for assessing embitterment. Its clinical application may significantly enhance the diagnostic assessment of embitterment in Turkish-speaking populations.
