Assessing the Turkish version of the Individual Work Performance Questionnaire (IWPQ) for its validity and reliability.
Article in BMC psychology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundsThis study aimed to assess the validity and reliability of the Turkish version of the Individual Work Performance Questionnaire (IWPQ).
methodsA total of 340 adult participants who had been working for at least 8 h a day completed the study questionnaire online. The questionnaire consisted of sections on demographics and socioeconomic characteristics, the IWPQ, and the ultrashortened version of the Utrecht Work Engagement Scale (UWES-3). Principal component analysis (PCA) with Promax rotation was conducted to assess the e three-factor structure for the Turkish version of the IWPQ. Cronbach's alpha was used to determine internal consistency. The intraclass correlation coefficient (ICC) was used to assess test-retest reliability. Spearman correlation coefficients were calculated between the IWPQ and UWES-3 scales to evaluate convergent validity.
resultsThe three factors accounted for a total variance ratio of 60.7%. Cronbach's alphas of three subscales (task performance, contextual performance, and counterproductive work behavior) were 0.894, 0.875, and 0.796, respectively. Test-retest reliability showed high agreement, with ICCs of 0.96, 0.98, and 0.91 for the respective scales. There was a statistically significant correlation between UWES-3 and the task performance subscale (ρ = 0.367 and p < 0.001), a statistically significant correlation between UWES-3 and the contextual performance subscale (ρ = 0.403 and p < 0.001), and a statistically significant correlation between UWES-3 and the CWB subscale (ρ=-0.352 and p < 0.001).
conclusionsThe Individual Work Performance Questionnaire (IWPQ) identifies work performance.The Turkish version of the IWPQ scales demonstrated validity and reliability in assessing individual work performance.
