Adaptation and psychometric properties of Psychological Skills Inventory for Sport (PSIS-R5) in Latvian athletes: Insights and implications for practice.

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
BACKGROUND AND
objectivePsychological skills are critical for high achievement and elite sports performance. However, there remains a lack of valid, reliable, and accessible instruments adapted to modern athletes. This highlights significant psychometric challenges in the existing tools currently available. While the Psychological Skills Inventory for Sport (PSIS-R5) is a commonly used tool in sports psychology worldwide, it has demonstrated various psychometric issues over time. A previous adaptation to the Latvian sports environment highlighted specific challenges in the Latvian context. It is important to note that these issues are not unique to the Latvian adaptation. A comprehensive review is necessary to address these broader psychometric concerns and ensure the instrument's suitability for contemporary athletes, including those in Latvia. Moreover, the adaptation process may offer insights and methodological guidance for similar efforts in other cultural contexts. The aims of this research were twofold: first, to review and adapt the PSIS-R5 for use in Latvia (PSIS-R5-L), ensuring its validity and reliability; and second, to assess the applicability of the PSIS-R5-L in elite sports settings by examining relationships between athletes' achievement levels and psychological skills.
methodsA total of 444 Latvian athletes aged between 18-43 (M = 21.32; SD = 6.52) completed the PSIS-R5 inventory to assess their psychological skills. The PSIS-R5 was re-translated into Latvian language (PSIS-R5-L) using forward-backward translation. Additionally, five sports psychologists participated in the study, providing evaluations of elite athletes' psychological skills using the PSIS-R5 inventory.
resultsSeries of Principal Components Analyses (PCA) were conducted to explore and validate the structure of the Latvian revisited adaptation of the PSIS-R5-L. As a result, a stable four-factor structure was obtained, consisting of 17 items with satisfactory fit indices (CFI = 0.968, RMSEA = 0.045 [90% CI: 0.034, 0.057], SRMR = 0.026). The findings indicate that the Latvian adapted PSIS-R5-L has appropriate psychometric properties, confirming its suitability for use in the Latvian sports environment. Comparisons between different athlete groups (elite, pre-elite, and amateur) revealed several correlations and statistically significant (p < 0.05) differences in psychological skills.
conclusionsThe PSIS-R5-L is a psychometrically robust and practically valuable tool for assessing athletes' psychological skills in Latvia. It offers coaches, sports psychologists, and practitioners an evidence-based instrument to evaluate and enhance mental skills across different athlete populations, supporting psychological preparation programs in both elite and amateur sports settings.
