The information assessment method (IAM) permits health professionals to systematically document the relevance, cognitive impact, use and health outcomes of information objects delivered by or retrieved from electronic knowledge resources. The companion review paper (Part 1) critically examined the literature, and proposed a 'Push-Pull-Acquisition-Cognition-Application' evaluation framework, which is operationalized by IAM. The purpose of the present paper (Part 2) is to examine the content validity of the IAM cognitive checklist when linked to email alerts.
A qualitative component of a mixed methods study was conducted with 46 doctors reading and rating research-based synopses sent on email. The unit of analysis was a doctor's explanation of a rating of one item regarding one synopsis. Interviews with participants provided 253 units that were analysed to assess concordance with item definitions.
The content relevance of seven items was supported. For three items, revisions were needed. Interviews suggested one new item. This study has yielded a 2008 version of IAM.
信息评估方法（IAM）使卫生专业人员能够系统地记录通过或从电子知识资源提供或检索的信息对象的相关性、认知影响、使用和健康结果。伴随的综述论文（第 1 部分）批判性地审查了文献，并提出了一个“推-拉-获取-认知-应用”评估框架，该框架通过 IAM 实现操作。本文（第 2 部分）的目的是检验与电子邮件警报相关联的 IAM 认知检查表的内容效度。
一项混合方法研究的定性部分，涉及 46 名阅读和评估基于研究的摘要的医生。分析的单位是一名医生对一篇摘要中一个项目的评分解释。对参与者的访谈提供了 253 个单位进行分析，以评估与项目定义的一致性。
有 7 个项目的内容相关性得到了支持。对于 3 个项目，需要进行修订。访谈建议增加一个新项目。这项研究产生了 2008 年版的 IAM。
