Chinese Translation and Psychometric Testing of the Peripheral Intravenous Catheter Insertion Self-Confidence Scale

Background and PurposeThere is no tool in China to evaluate self-confidence in peripheral intravenous catheter insertion,this study aims to translate the Peripheral intravenous Catheter Insertion Self-Confidence Scale (PVCS) into Chinese and evaluate its reliability and validity among nursing students. MethodsThe translation and validation followed Brislins model, including forward translation, back-translation, synthesis, expert review, and pre-testing to develop the Chinese version (C-PVCS). A convenience sample of 205 nursing students from Tianjin and Chongqing, China, was surveyed to assess reliability and validity ResultsThe Chinese version of the PVCS (C-PVCS)comprises 15 items in two dimensions: theoretical knowledge self-confidence (5 items) and operational skills self-confidence (10 items). The scales Cronbachs coefficient was 0.979, the split-half reliability was 0.944, and the test-retest reliability was 0.985. The average scale-level content validity index (S-CVI/Ave) was 0.966, and the item-level content validity index (I-CVI) ranged from 0.875 to 1.000. Exploratory factor analysis extracted two common factors, with a cumulative variance explained of 85.839%. For confirmatory factor analysis, the structural equation model fitting indices showed that the root mean square error of approximation (RMSEA) was 0.077, and the chi-square/degree of freedom ratio ({chi}2/df) was 2.22. ConclusionThe C-PVCS demonstrates excellent reliability and validity, making it a suitable tool for assessing nursing students self-confidence in peripheral intravenous catheter insertion.
