Despite the fact that many infertile couples have to decide about whether or not to choose donor conception, there is no predictive scale for evaluating the process of decision-making on donor conception and its determinants in such couples. The present study was conducted to develop a decision-making questionnaire for selecting donor conception and assess its psychometric properties in Iranian infertile couples.
This cross-sectional validation study was conducted based on the method developed by DeVellis (2012) in four steps at Milad Infertility Clinic, Mashhad, Iran. The dimensions of the concept of decisionmaking were determined in the first step based on the qualitative results obtained from 38 semi-structured in-depth interviews. Items that were appropriate for the questionnaire were developed in the second step using the qualitative data and a review of the literature. In the third step, the research team reviewed and eliminated some of the items. The fourth step evaluated the face, content and construct validity of the questionnaire through exploratory factor analysis on a sample of 220 infertile couples using convenience sampling and investigated its initial and final reliability.
Based on the results of the qualitative study, a pool of 170 items was developed, 101 of which were eliminated after revision due to ambiguity, repetition or their poor face and content validity and initial reliability. The questionnaire was evaluated for its construct validity with 69 items. After the exploratory factor analysis, the decisionmaking donor conception questionnaire (DMDCQ) having 51 items and seven factors, was finalized. All the factors had Cronbach's alpha values of 0.75-0.87 and intra-class correlation coefficients (ICC) greater than 0.7.
This study led to development of a valid and reliable scale for examining infertile couples' decisionmaking about whether or not to use donor conception as well as the determinants of this decision.
尽管许多不孕夫妇必须决定是否选择供体受孕，但目前尚无评估此类夫妇供体受孕决策过程及其决定因素的预测量表。本研究旨在编制一份供体受孕选择决策问卷，并评估其在伊朗不孕夫妇中的心理测量特性。
本横断面验证研究基于DeVellis（2012年）开发的方法，在伊朗马什哈德的米拉德不孕诊所分四个步骤进行。第一步，根据38次半结构化深入访谈的定性结果确定决策概念的维度。第二步，利用定性数据和文献综述编制适合问卷的项目。第三步，研究团队对部分项目进行审查并剔除。第四步，通过对220对不孕夫妇样本进行探索性因子分析，评估问卷的表面效度、内容效度和结构效度，并调查其初始信度和最终信度。
根据定性研究结果，编制了170个项目的题库，其中101个项目在修订后因表述模糊、重复、表面效度和内容效度差以及初始信度低而被剔除。对包含69个项目的问卷进行结构效度评估。经过探索性因子分析，最终确定了包含51个项目和7个因子的供体受孕决策问卷（DMDCQ）。所有因子的Cronbach's alpha值在0.75至0.87之间，组内相关系数（ICC）大于0.7。
本研究开发了一个有效且可靠的量表，用于检查不孕夫妇关于是否使用供体受孕的决策及其决策的决定因素。
