Translation and Validation of the Thai Version of the Quality Nursing Care Questionnaire (T-QNCQ)

Objective: The Quality Nursing Care Questionnaire (QNCQ) has been widely used to assess nurses’ perceptions of care quality. However, there was a lack of studies validating the QNCQ in Thai healthcare settings, highlighting the need for its adaptation. This study aimed to translate the QNCQ into Thai and evaluate its internal consistency and psychometric properties. Materials and Methods: A cross-sectional study design was used in this research. The Thai version (T-QNCQ) was a self-reported questionnaire consisting of 38 items across 5 response categories, covering 6 dimensions: physical environment, staff characteristics, preconditions, task-oriented activities, human-oriented activities, and patient outcomes. A sample of 380 registered nurses from tertiary government hospitals in Thailand was recruited using purposive and convenience sampling. To assess the validity of the translated scale, confirmatory factor analysis (CFA), descriptive statistics, and reliability testing were conducted. Results: The T-QNCQ demonstrated strong reliability and validity. The Cronbach’s alpha coefficient for the total scale was 0.98, with subscale values ranging from 0.86 to 0.94. Item-total correlations for the overall scale were positive, ranging from 0.61 to 0.84. Construct validity was supported by CFA, which yielded the following fit indices: comparative fit index=0.95, Tucker-Lewis index=0.94, root mean square error of approximation=0.05, and standardized root mean square residual=0.04. Conclusion: The T-QNCQ was found to be a reliable and valid tool for assessing nurses’ perceptions of care quality in Thai healthcare settings. These results provide valuable insights for nurse administrators and policymakers, aiding improvements in care delivery.
