当前的健康素养测量因仅测量阅读和算术技能而受到批评，而做出明智的健康决策需要更广泛的技能，特别是当信息经常通过口头和多媒体视频传达时。作者设计了 9 项健康任务和相应的 190 项评估，以更全面地衡量健康素养技能。 826 名年龄在 55 岁至 74 岁之间的参与者样本完成了评估，这些参与者是从学术普通内科诊所和伊利诺伊州芝加哥市的三个联邦合格健康中心招募的。使用分层因子分析和项目反应理论减少项目，形成包含 45 个项目的综合健康活动量表。所有 45 个项目都包含 1 个一般潜在特征，并且使用健康素养和整体认知功能的衡量标准，得出的量表显示出高可靠性和强大的构建效度。使用自我报告的一般、身体和心理健康状况的综合健康活动量表的预测有效性与广泛使用的健康素养测量相当或更好，具体取决于结果。尽管全面衡量了健康素养技能，但综合健康活动量表中的项目支持 1 个主要构建。具有类似的心理测量特性，根据评估的目的，当前的措施可能就足够了。
Current health literacy measures have been criticized for solely measuring reading and numeracy skills when a broader set of skills is necessary for making informed health decisions, especially when information is often conveyed verbally and through multimedia video. The authors devised 9 health tasks and a corresponding 190-item assessment to more comprehensively measure health literacy skills. A sample of 826 participants between the ages of 55 and 74 years who were recruited from an academic general internal medicine practice and three federally qualified health centers in Chicago, Illinois, completed the assessment. Items were reduced using hierarchical factor analysis and item response theory resulting in the 45-item Comprehensive Health Activities Scale. All 45 items loaded on 1 general latent trait, and the resulting scale demonstrated high reliability and strong construct validity using measures of health literacy and global cognitive functioning. The predictive validity of the Comprehensive Health Activities Scale using self-reported general, physical, and mental health status was comparable to or better than widely used measures of health literacy, depending on the outcome. Despite comprehensively measuring health literacy skills, items in the Comprehensive Health Activities Scale supported 1 primary construct. With similar psychometric properties, current measures may be adequate, depending on the purpose of the assessment.
