To assess the effectiveness of an online course for public librarians on helping patrons reduce saturated fat.
Pre- and posttest design along with a 6-month follow-up survey.
Online nutrition course.
100 (8 males, 92 females) completed the course, and 29 completed the follow-up survey.
Completion of an online course.
Self-efficacy, expectancies, and knowledge were assessed at pre- and posttest. Self-efficacy, expectancies, and use of course content were assessed at 6-month follow-up.
Paired-samples t tests.
Knowledge increased significantly (P < .001). Self-efficacy significantly (P < .001) increased from the pre- to posttest, and this increase remained significant at the 6-month follow-up as compared to pretest (P < .001). Expectancies also increased significantly from pre- to posttest (P < .001) and remained high at 6 months, but they were not significantly different from baseline (P = .178). At 6-month follow-up, 39% of the participants had used the information from the course to find resources for a patron with a health-related question, and 82% had used the information from the course to help a friend or family member.
This small pilot study with librarians shows that an online course can be an effective way to increase self-efficacy about helping patrons with nutrition-related questions.
评估面向公共图书馆馆员的在线课程在帮助读者减少饱和脂肪摄入方面的效果。
前后测设计以及为期6个月的随访调查。
在线营养课程。
100人（8名男性，92名女性）完成了该课程，29人完成了随访调查。
完成在线课程。
在前后测时评估自我效能感、期望和知识水平。在6个月随访时评估自我效能感、期望以及课程内容的使用情况。
配对样本t检验。
知识水平显著提高（P < .001）。自我效能感从前测到后测显著提高（P < .001），并且与前测相比，在6个月随访时这种提高仍然显著（P < .001）。期望也从前测到后测显著提高（P < .001），并且在6个月时仍然很高，但与基线相比无显著差异（P = .178）。在6个月随访时，39%的参与者使用课程中的信息为有健康相关问题的读者寻找资源，82%的参与者使用课程中的信息帮助朋友或家人。
这项针对图书馆馆员的小型试点研究表明，在线课程可以成为提高帮助读者解决营养相关问题的自我效能感的有效方式。
