This study aimed to develop the Chinese version of the totally implantable venous access port (TIVAP) self-management behavior scale for patients with cancer to provide a reliable tool for medical staff to judge patients with TIVAP self-management behavior.
This study employed a mixed-method exploratory design. The initial scale was developed through a literature review, expert meetings, and two-round Delphi expert consultation. The reliability indicators included retest reliability and Cronbach's alpha coefficients. The validity indicators included content, construct, convergent, discriminant, and criterion validity. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed for the validity analysis; 22 venous therapy experts participated in the Delphi expert consultation. A total of 500 patients were recruited from two third-class A hospitals in Guangdong Province, China, between July 2020 and January 2021 to test reliability and validity. A convenience sampling method was adopted.
The final scale comprised seven dimensions and 29 items. The content validity index (S-CVI) was 0.990. Cronbach's alpha coefficient and retest reliability of the scale were 0.931 and 0.900, respectively. The EFA results indicated a seven-factor structure, accounting for 65.68% of the total data variance. The results of the CFA showed that the CMIN/DF value was 2.348; the root mean square error of approximation value was 0.06; and the values of comparative fit index, incremental fit index, and Tucker-Lewis index were all >0.90. The factor loadings for all the items were >0.50, the composite reliability value was >0.70, and the average variance extracted (AVE) value was >0.50. Moreover, all absolute values of the correlation coefficients were less than the square root of the AVE for the seven dimensions. The total scores between the health promoting lifestyle profile-II revise (HPLP-IIR) and CPTSMBS were positively correlated (r = 0.465, p < 0.01).
The scale demonstrated good reliability and validity and can be applied in clinical practice to evaluate self-management behavior among patients using a TIVAP.
本研究旨在编制癌症患者完全植入式静脉输液港（TIVAP）自我管理行为量表中文版，为医护人员判断TIVAP患者自我管理行为提供可靠工具。
本研究采用混合方法探索性设计。初始量表通过文献回顾、专家会议及两轮德尔菲专家咨询编制而成。可靠性指标包括重测信度和克朗巴哈α系数。效度指标包括内容效度、结构效度、收敛效度、区分效度和效标效度。采用探索性因子分析（EFA）和验证性因子分析（CFA）进行效度分析；22名静脉治疗专家参与了德尔菲专家咨询。2020年7月至2021年1月期间，从中国广东省两家三级甲等医院招募了500例患者以测试信效度。采用便利抽样法。
最终量表包括7个维度和29个条目。内容效度指数（S-CVI）为0.990。量表的克朗巴哈α系数和重测信度分别为0.931和0.900。EFA结果显示为七因素结构，解释总数据方差的65.68%。CFA结果显示，CMIN/DF值为2.348；近似误差均方根值为0.06；比较拟合指数、增值拟合指数和塔克-刘易斯指数值均>0.90。所有条目的因子载荷>0.50，组合信度值>0.70，平均提取方差（AVE）值>0.50。此外，七个维度的相关系数绝对值均小于AVE的平方根。健康促进生活方式量表第二版修订版（HPLP-IIR）与CPTSMBS总分呈正相关（r = 0.465，p < 0.01）。
该量表具有良好的信效度，可应用于临床实践，以评估使用TIVAP患者的自我管理行为。
