Considering the key role of physicians in providing genetic counseling services and the lack of studies in this field in Iran, it seems necessary to design a valid and reliable instrument for measuring the awareness, attitude, and performance of general and specialist physicians in genetic counseling.
In this descriptive study, the design and psychometrics of the questionnaire were performed in 4 steps: first, defining the concept of awareness, attitude, and performance of general and specialist physicians in relation to genetic counseling by reviewing texts and articles; second, designing questionnaire items; third, determining the face and content validity by 10 university experts; and forth, determining reliability using Cronbach's alpha coefficient method.
The primary version of the questionnaire was designed taking into account 60 items during the first and second stages. In the third step, one item was removed and in the final version of the questionnaire 59 items and the content validity index (CVI) and content validity ratio (CVR) were reported to be 0.98 and 0.92, respectively. Reliability with Cronbach's alpha coefficient was determined 0.82.
The final questionnaire with 59 items had appropriate psychometric properties. This questionnaire has the ability to be used by health care providers in health care systems to measure the awareness, attitude, and performance of physicians about genetic counseling. The need for further studies is suggested to measure the other types of validity, such as the structural validity of the questionnaire.
考虑到医生在提供遗传咨询服务中的关键作用,以及伊朗在该领域缺乏相关研究,似乎有必要设计一种有效且可靠的工具来衡量普通医生和专科医生在遗传咨询方面的认知、态度和表现。
在这项描述性研究中,问卷的设计和心理测量学评估分4个步骤进行:首先,通过查阅文献和文章,界定普通医生和专科医生在遗传咨询方面的认知、态度和表现的概念;其次,设计问卷项目;第三,由10位大学专家确定表面效度和内容效度;第四,使用克朗巴赫α系数法确定信度。
在第一和第二阶段,考虑到60个项目设计了问卷的初稿。在第三步中,删除了一个项目,问卷的最终版本有59个项目,内容效度指数(CVI)和内容效度比率(CVR)分别报告为0.98和0.92。使用克朗巴赫α系数确定的信度为0.82。
最终的59项问卷具有适当的心理测量学特性。该问卷可供医疗保健系统中的医疗服务提供者用于衡量医生在遗传咨询方面的认知、态度和表现。建议进行进一步研究以衡量问卷的其他类型效度,如结构效度。
