Background:
Assessing 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.
Methods:
The 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).
Results:
According 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.
Conclusion:
The 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.
