Objective:To develop the pressure injury(PI)risk factor assessment scale among residents of pension institutions,and to test its reliability and validity.Methods:The literature review and semi-structured interview were used to form the item pool of the scale.The items of the scale were revised and finalized through experts consultation and pilot investigation.From March to May 2022,242 residents from 4 pension institutions in Henan Province were selected to conduct the first round of questionnaire survey.From June to August 2022,291 residents from other four pension institutions in Henan Province were selected to conduct the second round of questionnaire survey.Results:The final scale contains 2 dimensions and 9 items.The average content validity index was 0.98.Exploratory factor analysis extracted 2 factors,and the cumulative variance contribution rate was 69.890％.The confirmatory factor analysis revealed that the factor structure of the scale was stable.The Cronbach's αcoefficient,half-reliability and test-retest reliability of the total scale were 0.852,0.836 and 0.848,respectively.The cut-off value of the assessment scale was 19.Conclusion:The pressure injury risk factor assessment cale for PI has good reliability and validity.
