Intensive and critical-care nurses are the key to successful donor management in the critical-care setting. No studies measuring attitudes toward organ donor advocacy existed before 2011, when the 51-item Swedish "Attitudes Toward Organ Donor Advocacy Scale" was developed. The aim of this study was to translate, adapt and establish the psychometric properties of the North American version of the Flodén ATODAI (Attitudes Toward Organ Donor Advocacy Instrument) in terms of validity and reliability.
A multi-step approach was used: Initial translation; Back-translation; Review and synthesis of these translations; ( = 7) rated the prefinal version of the instrument for content validity index (CVI); made adjustments guided by the . Reliability testing with test and retest of the adjusted 46-item version was conducted using intraclass correlation coefficient (ICC), weighted kappa ( ), sign test, and Cronbach's alpha coefficient (α), ( = 50); and finally Delphi technique procedure with a preselected ( = 15).
The CVI was determined to be greater than the 0.05 significance level. Item level (I-CVI) ranged 0.82-1.0, with a mean of 0.97. Scale level (S-CVI) on the entire instrument was 0.97. Test-retest procedure was performed to estimate stability. In total, 34 of the items had good-to-high ICC. Accepting an ICC of ≥ 0.70 resulted in a total of 24 items. Homogeneity reliability was estimated by α and was calculated for these items where α = 0.90. In total, 20 of the items had a substantial or almost perfect and 23 showed a moderate . None of the items showed systematical differences. The Delphi technique procedure was used on the 22 items with ICC < 0.70 resulted in adjustments establishing that consensus was achieved.
Undertaking this multi-step, cross-cultural adaptation procedure has effectively ensured that the 46-item Flodén ATODAI [North American version] produces valid and reliable measurements.
重症监护和危重症护理护士是危重症环境下成功进行供体管理的关键。在2011年瑞典开发出包含51个条目的“器官捐献倡导态度量表”之前，尚无测量对器官捐献倡导态度的研究。本研究的目的是对北美版弗洛登器官捐献倡导态度量表（ATODAI）进行翻译、改编，并从效度和信度方面确立其心理测量特性。
采用多步骤方法：初步翻译；回译；对这些翻译进行审查和综合；7名专家对量表预终版的内容效度指数（CVI）进行评分；根据评分结果进行调整。使用组内相关系数（ICC）、加权kappa系数（ ）、符号检验和克朗巴赫α系数（α）对调整后的46个条目版本进行重测信度检验（n = 50）；最后对预先选定的15名专家采用德尔菲技术程序。
CVI被确定大于0.05显著性水平。条目水平（I-CVI）范围为0.82 - 1.0，平均为0.97。整个量表的量表水平（S-CVI）为0.97。进行重测程序以评估稳定性。总共有34个条目具有良好到高度的ICC。接受≥0.70的ICC得出共有24个条目。通过α估计同质性信度，并对这些条目进行计算，其中α = 0.90。总共有20个条目具有实质性或几乎完美的 ，23个条目显示出中等的 。没有条目显示出系统性差异。对ICC < 0.70的22个条目采用德尔菲技术程序进行调整，确定达成了共识。
采用这种多步骤、跨文化适应程序有效地确保了46个条目的弗洛登ATODAI（北美版）产生有效且可靠的测量结果。
