Psychometric properties of the Chinese version of professional commitment questionnaire among nursing students: validation using classical test theory and item response theory.
Article in BMC nursing, 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
backgroundAssessing professional commitment is crucial for understanding workforce dynamics, particularly in healthcare. The Professional Commitment Questionnaire (PCQ) is a concise tool designed for such assessments. This study aimed to translate and culturally adapt the PCQ into Chinese and validate its psychometric properties among nursing students.
methodsThe translation and cross-cultural adaptation were conducted using the translation, review, adjudication, pre-testing, and documentation (TRAPD) methodology. Psychometric properties were assessed through classical test theory (CTT) and item response theory (IRT).
resultsAccording to CTT, the content validity (S-CVI = 1), convergent validity (AVE = 0.792), internal consistency reliability (Cronbach's alpha = 0.878), and test-retest reliability (ICC = 0.782) of the Chinese version of the PCQ (CV-PCQ) were acceptable. According to IRT, item fit (infit and outfit MNSQ ranging from 0.552 to 1.077) and differential item functioning (p values ranging from 0.164 to 0.870) were acceptable.
conclusionThe CV-PCQ demonstrated acceptable content validity, convergent validity, structural validity, internal consistency reliability, and test-retest reliability, as well as acceptable item fit and differential item functioning among Chinese nursing students. These specific psychometric properties support its utility as a brief assessment tool for nursing educators, researchers, and policymakers.
