OBJECTIVE
To assess the change in the perception of self-efficacy of Primary Health Care professionals to provide dietary advice using the Protocols based on the Brazilian Dietary Guidelines for Individual Dietary Advice, after completing a massive online open course (MOOC).
METHODS
Uncontrolled community trial. The study population comprises degree-holding healthcare professionals working in Primary Health Care in 64 small municipalities in Brazil. The intervention was a massive online open course. The outcome was assessed by a validated scale that measures the perception of self-efficacy to provide dietary advice based on the Protocols based on the Brazilian Dietary Guidelines. The mean score was calculated before and after the intervention and the change in score was tested with paired t-test (p-value<0.05).
RESULTS
Among the 1,201 health professionals, the average self-efficacy score increased from 23.71 to 37.31 after the intervention (p-value<0.001), an increase that was significant in all professional categories.
CONCLUSION
The massive online open course increased the perception of self-efficacy of Primary Health Care professionals to provide individual dietary advice based on the Protocols based on the Brazilian Dietary Guidelines.
目的
在完成大规模在线开放课程（MOOC）后，评估初级卫生保健专业人员使用基于巴西膳食指南的个人饮食建议协议提供饮食建议的自我效能感变化。
方法
非对照社区试验。研究人群包括在巴西64个小市镇的初级卫生保健机构工作的持有学位的卫生专业人员。干预措施是大规模在线开放课程。通过一个经过验证的量表评估结果，该量表测量基于巴西膳食指南的协议提供饮食建议的自我效能感。在干预前后计算平均分，并使用配对t检验（p值<0.05）检验分数变化。
结果
在1201名卫生专业人员中，干预后自我效能感平均得分从23.71提高到37.31（p值<0.001），在所有专业类别中这一提高均具有显著性。
结论
大规模在线开放课程提高了初级卫生保健专业人员基于巴西膳食指南的协议提供个人饮食建议的自我效能感。
