Abstract:
Objective To analyze and evaluate the reliability and validity of a 30-items initial survey scale concerning the knowledge , attitude and behavior in cancer patients with peripherally inserted central catheters ( PICC) .Methods The initial items were analyzed and thirty items were screened out by combining extreme group discrimination method , correlation analysis and factor analysis .The reliability and validity of 30-items survey scale was also evaluated .Results The Cronbach’s alpha coefficients of knowledge , attitude, and behavior were respectively 0.729, 0.826 and 0.765, the split-half reliability of knowledge , attitude, and behavior were 0.705, 0.774 and 0.735, the Cronbach’s alpha coefficients of overall scale was 0.834, and the split-half reliability of overall scale was 0.725.The correlation coefficients of each item in content validity of knowledge, attitude, and behavior were among 0.346-0.584, 0.652-0.735 and 0.567-0.673.According to the theoretical model , three common factors were extracted by exploratory factor analysis .By using two factor analysis and orthogonal rotation , the cumulative variance contribution rate of three common factors from 24 items was 40.388%, factor loading value of each item was more than 0.4 and communality of each item was more than 0.2.Conclusions Self-designed survey scale of the cancer patients with PICC has met the criteria of statistics after rigorous psychometric analysis , and has the potential to be used in clinic but also still needs for further improvement .
