Abstract:
Objective To translate the knowledge,attitude and practice assessment scale for pregnant women on UI(KAP-IU)into Chinese and evaluate its reliability and validity,so as to provide healthcare professionals with a tool in Chinese to assess the knowledge,attitude and practice of pregnant women with UI.Methods The KAP-UI scale was translated into a Chinese version following the international standard for cross-cultural adaptation process.A total of 456 pregnant women attending the outpatient clinics were selected for trial of the Chinese version of KAP-UI with the method of convenience sampling.Reliability and validity were further assessed based on Rash model and classic measurement indicators.Results A total of 430 pregnant women validly responded to the survey with the Chinese version of KAPS-UI.The Chinese version of the KAP-UI comprised a total of 23 items.It conformed with the unidimensional assumption of the Rasch model,which explained 66.1%of the variance.Both individual and entry separation reliabilities were>0.8,with the separation index was approximately equal to 3.The information-weighted mean square fit statistic(Infit MnSq)and the unweighted mean square fit statistic(Outfit MnSq)values of the items were from 0.473 to 1.611.The Point-Measure correlation coefficients(Pt-Measure Corr)were from 0.293 to 0.731,with an average individual ability higher than the average item difficulty by 0.343 Logits.The Cronbach's α coefficient of the scale was 0.783,with the test-retest reliabilities of the three dimensions(knowledge,attitude and behaviour)at 0.751,0.815,and 0.760,respectively.The Item-level content validity index(I-CVI)were found from 0.810 to 1.000 and the scale-level content validity index(S-CVI)was 0.824.Conclusions The Chinese version of the KAP-IU scale demonstrates a good reliability and validity among pregnant women in China,with mode rate difficulty.Therefore,it is a reliable tool for assessment of the knowledge,attitudes and practices of pregnant women with UI.
