Introduction Competence in research methodology and protocol development is essential for medical residents to integrate evidence-based medicine into clinical practice. Online Educational Interventions (OEIs) have been implemented as a structured approach to enhance these skills. This study assesses the impact of an OEI on research methodology knowledge and protocol development among first-year medical residents. Methods A quasi-experimental, prospective study was conducted from June 2022 to February 2023 at the Family Medicine Unit No. 1 of the Mexican Social Security Institute (IMSS) in Victoria, Mexico. First-year residents from multiple specialties participated in a structured OEI designed to strengthen competencies in research methodology. Pre- and post-intervention assessments were carried out using a custom-designed questionnaire validated through expert review. Data were analyzed using Wilcoxon signed-rank and paired Student's t-tests, with statistical significance set at p < 0.05. Results A total of 101 medical residents were enrolled in the study, of whom 65 completed the intervention. Among the completers, 39 (60.0%) were female residents, and 26 (40.0%) were male residents. Family Medicine was the most represented specialty, comprising 29 participants (44.6%). Post-intervention assessments demonstrated statistically significant improvements across all evaluated domains (p < 0.05), with the most pronounced gains observed in data collection procedures, participant selection, and study design. The assessment tool showed high internal consistency (Cronbach's alpha = 0.84). Conclusions Structured OEIs significantly improve research methodology knowledge and protocol development skills in medical residents. These findings support their integration into residency training programs to strengthen research capacity and advance evidence-based practice.
引言 研究方法和方案制定能力对于医学住院医师将循证医学融入临床实践至关重要。在线教育干预（OEIs）已被作为一种结构化方法来提升这些技能。本研究评估了一种在线教育干预对一年级医学住院医师研究方法知识和方案制定的影响。
方法 2022年6月至2023年2月在墨西哥维多利亚市墨西哥社会保障局（IMSS）第一家庭医学科进行了一项准实验性前瞻性研究。来自多个专业的一年级住院医师参与了一项旨在强化研究方法能力的结构化在线教育干预。干预前后的评估使用了经专家评审验证的定制问卷。数据采用Wilcoxon符号秩检验和配对t检验进行分析，统计学显著性设定为p < 0.05。
结果 共有101名医学住院医师纳入研究，其中65人完成了干预。在完成者中，女性住院医师39人（60.0%），男性住院医师26人（40.0%）。家庭医学是参与人数最多的专业，有29名参与者（44.6%）。干预后的评估显示，所有评估领域均有统计学显著改善（p < 0.05），在数据收集程序、参与者选择和研究设计方面的提升最为显著。评估工具显示出较高的内部一致性（Cronbach's alpha = 0.84）。
结论 结构化在线教育干预显著提高了医学住院医师的研究方法知识和方案制定技能。这些发现支持将其纳入住院医师培训项目，以增强研究能力并推进循证实践。
