利用共享决策和循证实践的概念框架，开发了一个门户网站，作为通用(非特定疾病)量身定做的干预措施，以提高普通公众的健康素养技能。评估门户网站与在现实生活环境中不干预相比的效果。这是一项实用的随机对照平行试验，对96名有4岁孩子的父母进行了简单随机。父母被分配进入门户网站或不接受干预，并分配了三项任务在三周内执行。这些任务包括一项搜索任务，一项关键的评估任务，以及报告对参与的看法。数据是从2011年3月到6月收集的。研究发现，使用门户网站可以改善人们对搜索健康信息的态度。这一变量被确定为两个样本中最重要的搜索意向预测因子。与会者认为该门户网站具有良好的可用性、有用性和可信度。与未接受干预的组相比，干预组在循证信息的使用、批判性评估技能和参与性方面略有增加，但这些差异在统计学上并不显著。尽管这项研究的动力不足，但我们发现，门户网站可能会对搜索健康信息的态度产生积极影响。此外，与会者认为门户网站是一个相关的工具。重要的是继续试验基于网络的资源，以增加用户对卫生保健决策的参与。ClinicalTrials.gov NCT01266798
Using the conceptual framework of shared decision-making and evidence-based practice, a web portal was developed to serve as a generic (non disease-specific) tailored intervention to improve the lay public's health literacy skills. To evaluate the effects of the web portal compared to no intervention in a real-life setting. A pragmatic randomised controlled parallel trial using simple randomisation of 96 parents who had children aged <4 years. Parents were allocated to receive either access to the portal or no intervention, and assigned three tasks to perform over a three-week period. These included a searching task, a critical appraisal task, and reporting on perceptions about participation. Data were collected from March through June 2011. Use of the web portal was found to improve attitudes towards searching for health information. This variable was identified as the most important predictor of intention to search in both samples. Participants considered the web portal to have good usability, usefulness, and credibility. The intervention group showed slight increases in the use of evidence-based information, critical appraisal skills, and participation compared to the group receiving no intervention, but these differences were not statistically significant. Despite the fact that the study was underpowered, we found that the web portal may have a positive effect on attitudes towards searching for health information. Furthermore, participants considered the web portal to be a relevant tool. It is important to continue experimenting with web-based resources in order to increase user participation in health care decision-making. ClinicalTrials.gov NCT01266798
