Abstract:
Objective To develop a Discharge Readiness Scale for Patients with PICC and to test its reliability and validity.Methods Based on the Meleis transition theory,the initial version of the scale was formed through literature review,qualitative interview,expert enquiry and pre-investigation.Patients with PICC in 2 tertiary hospital in Hangzhou from December 2023 to March 2024 were selected to investigate the reliability and validity of the scale by convenience sampling.Results 352 questionnaires were distributed,and 340 valid questionnaires were recovered,and the validity recovery rate was 96.59％.The exploratory factor analysis extracted 4 common factors with the cumulative variance contribution rate of 80.568％.The confirmatory factor analysis showed that all evaluation indicators of the scale were within ideal standards.The item-level content validity index ranged from 0.79 to 1.00,and the scale-level content validity index was 0.96.The total Cronbach's α coefficient of the scale was 0.963,and the split-half reliability coefficient was 0.889.The Chinese version of the Discharge Readiness Scale was used as a calibration tool,and the correlation coefficients between the total score of the scale and the scores of each dimension and the calibration tool were 0.788 and 0.567～0.878,respectively(all P＜0.05).The Discharge Readiness Scale for Patients with PICC included 26 items in 4 dimensions including physiological and psychological status,knowledge of catheter maintenance,catheter maintenance capability and social support.Conclusion The Discharge Readiness Scale for Patients with PICC has good reliability and validity,and can be used to evaluate the level of discharge readiness among patients with PICC.
