To measure the change in contraceptive knowledge after interaction with a web-based contraception education resource in an online cohort of potential users.
We conducted a cross-sectional online survey of reproductive-aged, biologically female respondents using Amazon Mechanical Turk. Respondents provided demographic characteristics and responded to 32 contraceptive knowledge questions. We assessed contraceptive knowledge before and after interaction with the resource and compared the number of correct answers using Wilcoxon signed-rank test. We used univariate and multivariable logistic regression to identify respondent characteristics associated with an increase in the number of correct answers. We calculated System Usability Scale scores to assess ease of use.
A convenience sample of 789 respondents were included in our analysis. Prior to resource use, respondents had a median of 17/32 correct contraceptive knowledge responses (interquartile range [IQR] 12-22). The number of correct answers increased to 21/32 (IQR 12-26, p < 0.001) after viewing the resource; 556 (70.5%) had an increase contraceptive knowledge. In adjusted analyses, respondents who were never married (adjusted odds ratio [aOR] 1.47, 95% CI 1.01-2.15), or thought decisions about birth control should be made by themselves (aOR 1.95, 95% CI 1.17-3.26) or in conjunction with a clinician (aOR 2.09, 95% CI 1.20-3.64) were more likely to have an increase in contraceptive knowledge. Respondents reported a median system usability score of 70 out of 100 (IQR 50-82.5).
These results support the effectiveness and usability of this online contraception education resource among this sample of online respondents. The educational resource could effectively augment contraceptive counseling in the clinical setting.
Use of an online contraception education resource improved contraceptive knowledge among reproductive-age users.
在潜在用户的在线队列中，通过与基于网络的避孕教育资源进行互动，衡量避孕知识的变化。
我们使用亚马逊 Mechanical Turk 对育龄期、生物学女性受访者进行了一项横断面在线调查。受访者提供人口统计学特征，并回答了 32 个避孕知识问题。我们评估了与资源互动前后的避孕知识，并使用 Wilcoxon 符号秩检验比较了正确答案的数量。我们使用单变量和多变量逻辑回归来确定与正确答案数量增加相关的受访者特征。我们计算了系统可用性量表分数以评估易用性。
我们的分析纳入了 789 名方便样本的受访者。在使用资源之前，受访者的正确避孕知识回答中位数为 17/32（四分位距 [IQR] 12-22）。观看资源后，正确答案数量增加到 21/32（IQR 12-26，p<0.001）；556 名（70.5%）的避孕知识有所增加。在调整分析中，从未结婚的受访者（调整后的优势比 [aOR] 1.47，95%置信区间 [CI] 1.01-2.15），或认为避孕决策应由自己（aOR 1.95，95%CI 1.17-3.26）或与临床医生一起做出（aOR 2.09，95%CI 1.20-3.64）更有可能增加避孕知识。受访者报告的系统可用性中位数为 100 分中的 70 分（IQR 50-82.5）。
这些结果支持在这个在线受访者样本中，这种在线避孕教育资源的有效性和易用性。该教育资源可在临床环境中有效补充避孕咨询。
使用在线避孕教育资源提高了育龄期用户的避孕知识。
