The signed donor card is an important method to overcome the shortage of organs for transplantation. A valid and reliable scale is necessary to have with the development of interventions to increase the signed donor card. This study aimed to develop and psychometric testing of the Signed Donor Card (SDC) in an Islamic society. This methodological study was conducted in Hamadan city, Iran in 2018 on 600 employees of offices. A 46-item scale was developed. It was assessed by face, content, and construct validities. Reliability was examined using the calculation of the Cronbach's α and test-retest method. The SPSS software version 22 and Mplus version 7.4 were used for data analysis. Our scale demonstrated acceptable internal consistency (α = 0.58-0.93) and good test-retest reliability (ICC = 0.76). The fitness indices for the confirmatory factor analysis (CFA) indicated that the model fit was good. CFA revealed nine standalone components including attitude, subjective norms, intention, anticipated regret, descriptive norms, perceived control, knowledge, non-cognitive beliefs, and religious beliefs. Convergent validity and discriminant validity were established. This study provided evidence concerning the validity and reliability of SDC scale. It can be used for the development and implementation of effective interventions for increasing signed donor card with the consideration of contextual and cultural situations.
签署的捐献卡是克服器官移植短缺的重要方法。随着增加签署捐献卡干预措施的发展，有必要拥有一个有效和可靠的量表。本研究旨在开发和测试伊斯兰社会中签署捐献卡（SDC）的心理计量学。这是 2018 年在伊朗哈马丹市进行的一项方法学研究，共有 600 名办公室员工参与。开发了一个包含 46 个项目的量表。通过表面、内容和结构效度进行评估。使用 Cronbach's α 计算和重测法评估信度。数据分析采用 SPSS 软件 22 版和 Mplus 软件 7.4 版。我们的量表显示出可接受的内部一致性（α=0.58-0.93）和良好的重测信度（ICC=0.76）。验证性因子分析（CFA）的拟合指数表明模型拟合良好。CFA 显示了九个独立的组成部分，包括态度、主观规范、意图、预期后悔、描述性规范、感知控制、知识、非认知信念和宗教信仰。建立了收敛有效性和判别有效性。本研究提供了关于 SDC 量表的有效性和可靠性的证据。可以考虑到情境和文化情况，使用该量表来开发和实施增加签署捐献卡的有效干预措施。
