Purpose: To develop a Chinese version of the State Behavioral Scale (SBS-C) and to evaluate its reliability and validity for sedation assessment in mechanically ventilated children in China.
Design and methods: Cross-sectional survey design was used in a two-part study of mechanically ventilated children, aged 6 weeks to 6 years. A total 172 children and 145 children were recruited from Jan-Dec 2017 and Jan-Dec 2018, respectively, at a tertiary care pediatric hospital in southeast China. Following translation of the scale, the content validity was established by the content validity index, internal consistency was established using Cronbach's α, and construct validity was confirmed by correlation with a similar well-recognized scale, the COMFORT Scale-Chinese version (CS-C).
Results: The content validity index for the seven scale dimensions ranged from 0.83 to 1.0 and for the full scale was 0.932. In the first study, Cronbach's α for the full SBS-C was 0.986 and for the seven scale dimensions ranged from 0.973 to 0.983; similarly, in the second study, Cronbach's α for the full scale was 0.983 and for the seven dimensions ranged from 0.977 to 0.987. The correlation coefficient between scores of the SBS-C and the CS-C was 0.919 (P < .01).
Conclusions: The SBS-C is valid, reliable, and responsive and is suitable for assessing sedation in mechanically ventilated children in China.
Implications for practice: The SBS-C can be used for sedation assessment in mechanically ventilated children in China, guiding decision making and the provision of care, and optimizing patient safety.
