Validation of the Spanish version of the Psychological Flexibility Sports Scale (PFSS).

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: Psychological flexibility has been conceptualized as the capacity to relate to internal experiences, maintain focus on the present moment, thereby allowing individuals to act according to the context in pursuit of their goals and values. It is a psychological construct related to mental health, where there is an increasing body of research that highlights its importance in athletic performance. The Psychological Flexibility Sports Scale (PFSS) is the first psychological flexibility scale specifically designed for use in sports. It has only been validated in a limited number of cultural contexts. Concerning this, the study aims to translate the PFSS into Spanish (ES-PFSS), thereby analyzing and identifying the psychometric properties of the ES-PFSS among native Spanish athletes or those with medium to high proficiency in Spanish. Methods: The sample comprised 146 participants who practiced both team-based and individual sports. (Age 33.95 ± 11.69 years, 63.014% male). Statistical analysis was performed for reliability (internal consistency and temporal stability), construct validity, and criterion validity. Results and discussion: The scale was confirmed to be unidimensional through confirmatory factor analysis. Significant results were found for the evaluation of construct validity. The ES-PFSS demonstrated solid criterion validity related to other constructs of psychological flexibility and perceived athletic performance. The reliability study proved to be significant, with excellent internal consistency (Cronbach's
