Abstract:
Objective To develop a knowledge-attitude-practice assessment scale for home prevention and man-agement of parastostomy hernia in ostomy patients,and to test its reliability and validity,to provide a reliable tool for evaluating the knowledge and practice level of home prevention and management of parastostomy hernia in pa-tients with ostomy.Methods Based on the theory of knowledge,attitude and practice,the initial scale was generat-ed through literature review,semi-structured interviews,expert correspondence,research group discussion and pre-sur-vey.From May to December 2023,685 patients with ostomy from the ostomy clinic of a tertiary hospital in Tianjin were investigated by purpose sampling method,and the reliability and validity were tested.Results A total of 673 valid questionnaires were collected,the results showed that the knowledge-attitude-practice assessment scale for pre-venting and managing parastomal hernia of ostomy patients at home included 3 dimensions of knowledge,attitude and practice,with a total of 27 items.The response rates of 2 rounds of the questionnaire were both 100％;the au-thority coefficients were all 0.915;the Kendall's coefficients of concordance were 0.279 and 0.301,respectively.The content validity index of each item was 0.875～1.000;the content validity index of the average scale level was 0.988;after 2 exploratory factor analysis,the cumulative variance contribution rate was 65.920％.The results of con-firmatory factor analysis showed that the model had a good fit,with a chi-square degree of freedom ratio(/df)of 1.945,the fitting goodness index(GFI)of 0.851,the comparative goodness of fit index(CFI)of 0.919,the root means square error of approximation(RMSEA)of 0.060.The Cronbach's alpha coefficient result of the scale is 0.957,with a test-retest reliability of 0.826 and a half reliability of 0.934.Conclusion The knowledge-attitude-practice assessment scale has good reliability and validity,and can be used as an assessment tool for home prevention and management of parastostomy hernia in ostomy patients.
