Translation, cross-cultural adaptation, reliability, and validity of the Chinese version of the intensive care unit environment stress scale for pediatric patients

PURPOSE: There is currently a lack of understanding of children's experience in the pediatric intensive care unit (PICU) environment. Additionally, pediatric patients may experience post-PICU syndrome following discharge. Thus, we aimed to adapt and evaluate the psychometric properties of a tool specifically for use with children in the PICU.

DESIGN AND METHODS: According to Brislin's Model, the Intensive Care Unit Environment Stress Scale (ICUESS) was translated both forward and backward and adapted cross-culturally. A total of 210 PICU patients were selected from four hospitals in XXX to analyze the final translated version of the questionnaire, the Pediatric Intensive Care Unit Environmental Stress Scale (PICUESS). Content validity, exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to assess the validity, while reliability was assessed using Cronbach's alpha and split-half reliability analysis.

RESULTS: For PICUESS, seven of 42 items were modified. Content validity was high (overall = 0.96, item validity = 0.8 to 1.0). Exploratory factor analysis revealed eight common factors (Kaiser-Meyer-Olkin = 0.857, significant Bartlett's test). The results of the CFA indicate that the scale model fits well across the 8 factors. The entire scale demonstrated excellent internal consistency (Cronbach's alpha = 0.934). The overall split-half reliability was 0.935.

CONCLUSIONS: The Chinese version of PICUESS demonstrates good reliability and validity, making it suitable for assessing pediatric patients' perceptions of the PICU environment.

PRACTICE IMPLICATIONS: The PICUESS can assist healthcare professionals in providing personalized environment care for PICU patients. It has the potential to serve as a tool for further testing and international comparisons of pediatric patients' perceptions of the PICU environment.
