ABSTRACT
Objective:To develop the nursing staff's perception scale of patients′ suicide risk and test its reliability and validity, so as to provide basis for managers to formulate training strategies for nurses' suicide gatekeepers.Methods:This was a cross-sectional study. Based on cognitive-experiential self-theory, and on the basis of literature review and semi-structured interviews at home and abroad, a scale item pool was formed, and an initial scale was formed through expert inquiry and pre-investigation. In September, 2022, a cross-sectional survey was conducted among 459 nurses from three tertiary general hospitals and oncology hospitals by convenience sampling method in Jinan and Dezhou, Shandong Province. SPSS25.0 and AMOS23.0 software were used to analyze the items and test the reliability and validity of the scale.Results:The formal scale included three dimensions, namely, cognitive judgment, emotional evaluation, and concern, with 15 items in total. Exploratory factor analysis extracted three common factors, and the cumulative variance contribution rate was 67.845%. The results of confirmatory factor analysis showed that each test quantity of the fitness of the formal scale model is within the acceptable range and loads of 15 items in the corresponding factors were all >0.45; the content validity index S-CVI of the scale was 0.972, Cronbach′s α coefficient of the total scale was 0.907, and the half reliability was 0.814. Conclusion:The scale of nurses′ perception of patients′ suicide risk has good reliability and validity, and it can be used to evaluate nurses′ perceptions of patients′ suicide risk.
