Abstract
AimThis study aimed to develop and validate a scientific and standardized knowledge, attitude and practice questionnaire of pediatric nurses’ preventive care for central venous device-related thrombosis among hospitalized children. BackgroundPediatric nurses play a significant role in the prevention of central venous device-related thrombosis for hospialized children. However, the status of pediatric nurses’ knowledge, attitude and practice of central venous device-related thrombosis prevention has not been revealed due to the lack of assessment tools. MethodsThis questionnaire was framed by the theory of knowledge, attitude and practice. The item pool was compiled through a literature review and a preliminary questionnaire was formed based on expert consultation. A total of 457 pediatric nurses from 10 tertiary class A general hospitals and specialized pediatric hospitals in China were selected for pre-survey. Item analysis, reliability and validity test were conducted to refine and evaluate the items to form a formal questionnaire. ResultsA total of 54 items were proposed in three dimensions of knowledge, attitude and practice. In the exploratory factor analysis, five, three and three common factors were extracted for each dimension, accounting for 60.552%, 89.829% and 84.258% of the total variance, respectively. The content validity index of the three dimensions ranged from 0.968 to 1.000 at the scale level and from 0.833 to 1.000 at the item level. The Cronbach's α coefficients for the total questionnaire and each dimension were between 0.926 and 0.973. The retest reliability for the total questionnaire and each dimension was between 0.688 and 0.898. ConclusionThe proposed questionnaire has good reliability and validity and it can be applied to evaluate pediatric nurses' knowledge, attitude and practice in preventing central venous device-related thrombosis for hospitalized children.
