Lack of interest has been cited by many studies as the predominant cause for students undervaluing the subject of Community Medicine. However, there are few valid and reliable tools that could measure this interest. To develop and validate a questionnaire to measure a medical student's interest in the subject of Community Medicine.
Cross-sectional study conducted at MTMC Jamshedpur. The Community Medicine Interest Questionnaire (CMIQ) was developed in two phases: item generation and item reduction. Items were generated through a review of the literature, focused group discussions, and in-depth interviews. In the item reduction phase, the content and construct validity of the questionnaire were ascertained. Content validity was carried out by a group of experts based on three parameters: the interrater agreement on the representativeness of the item, the interrater agreement on the clarity of the items, and the content validity index. The construct validity was ascertained through pilot testing of 480 responses from undergraduate medical students. Exploratory factor analysis through principal axis factoring and Promax rotation.
Twenty-five items were generated. Three of these items were removed following expert validation. Furthermore, three items were removed after pilot testing. The resulting CMIQ consisted of 19 items distributed over three dimensions: feeling, value, and predisposition to reengage toward the subject. The internal consistency of each of the subscales was ascertained.
CMIQ is a valid and reliable tool that can be used to measure such interest for providing educational interventions.
许多研究指出，缺乏兴趣是学生轻视社区医学这门学科的主要原因。然而，几乎没有有效且可靠的工具能够衡量这种兴趣。目的是开发并验证一份用于测量医学生对社区医学学科兴趣的问卷。
在贾姆谢德布尔的MTMC进行横断面研究。社区医学兴趣问卷（CMIQ）分两个阶段开发：项目生成和项目缩减。通过文献回顾、焦点小组讨论和深入访谈生成项目。在项目缩减阶段，确定问卷的内容效度和结构效度。内容效度由一组专家基于三个参数进行评估：项目代表性的评分者间一致性、项目清晰度的评分者间一致性以及内容效度指数。通过对480名本科医学生的回答进行预测试来确定结构效度。采用主轴因子分析和普罗麦克斯旋转进行探索性因子分析。
共生成25个项目。经过专家验证后删除了其中3个项目。此外，预测试后又删除了3个项目。最终的CMIQ由19个项目组成，分布在三个维度上：感受、价值和重新参与该学科的倾向。确定了每个子量表的内部一致性。
CMIQ是一种有效且可靠的工具，可用于测量这种兴趣，以提供教育干预措施。
