Abstract:

Objective To develop and test the reliability and validity of a Fear of Movement Assessment Scale for patients with peripherally inserted central catheters（PICC），and to make a preliminary application. The aim is to provide an effective tool for nurses to accurately assess the level of fear of movement in patients with PICC and to develop targeted interventions. Methods Based on the psychological imagination belief model，the initial version of the scale was formed through literature review，semi-structured interviews，expert correspondence and a pre-survey. From February to April 2024，211 patients with PICCs were recruited from a tertiary hospital in Wuhan by convenience sampling for project analysis and reliability and validity test. From May to July 2024，256 patients with PICCs from 3 tertiary hospitals in Wuhan were selected by convenience sampling method for further validating the structural validity of the scale and for preliminary application. Results A total of 203 valid questionnaires were collected in February to April 2024，228 valid questionnaires were collected in May to July 2024. The fear of movement assessment scale for patients included 4 dimensions，including the perception of risk，belief of fear，avoidance of movement，and dysfunction，with a total of 17 items. The Cronbach’s α coefficient was 0.922；the split-half reliability was 0.867；the test-retest reliability was 0.958. The content validity index at the item level was 0.867~1.000，and the content validity index at the scale level was 0.951. Both exploratory factor analysis and parallel analysis extracted 4 factors. The cumulative variance contribution rate was 61.348%. Confirmatory factor analysis showed that the model fitted well. The preliminary application results showed that the score of fear of movement in patients with PICCs was 53.95±11.08，which was moderately high. Conclusion The Fear of Movement Assessment Scale for patients with PICCs has good measurement properties，and can be used to assess the degree of fear of movement in patients with PICCs.

摘要：

目的 编制PICC置管患者运动恐惧评估量表，检验其信效度并进行初步应用，为护士准确评估PICC置管患者的运动恐惧程度、制订针对性的干预措施提供有效工具。 方法 以心理想象信念模型为理论基础，通过文献回顾、半结构式访谈、专家函询及预调查形成初始版量表。2024年2月—4月，采用便利抽样法，选取在武汉市某三级甲等综合医院就诊的211例PICC置管患者进行调查，并进行项目分析和信效度检验。2024年5月—7月，采用便利抽样法，选取在武汉市3所三级甲等综合医院就诊的256例PICC置管患者进行调查，以进一步验证量表的结构效度并进行初步应用。 结果 2024年2月—4月共回收有效问卷203份，2024年5月—7月共回收有效问卷228份。PICC置管患者运动恐惧评估量表包括危险感知、恐惧信念、运动回避及功能紊乱4个维度，共17个条目。总量表的Cronbach’s α系数为0.922，折半信度为0.867，重测信度为0.958。条目水平的内容效度指数为0.867~1.000，量表水平的内容效度指数为0.951；探索性因子分析及平行分析均提取出4个因子，累计方差贡献率为61.348%。验证性因子分析结果显示，模型拟合良好。初步应用结果显示，PICC置管患者运动恐惧得分为（53.95±11.08）分，处于中等偏高水平。 结论 PICC置管患者运动恐惧评估量表具有良好的测量学属性，可用于评估PICC置管患者的运动恐惧程度。
