In the information search task, older adults performed worse than younger adults (F1,96= 18.0, P< .001). However, there was a significant age × condition interaction indicating that while younger adults outperformed older adults in the hierarchical condition (F1,96= 25.2, P< .001), there were no significant age-related differences in the tag-based condition, indicating that older adults performed as well as younger adults in this condition. Conclusions: Access to online health information is increasing in popularity and can lead to a more informed health consumer. However, usability barriers may differentially affect older adults. The results of the current study suggest that the design of health information websites that take into account age-related changes in cognition can enhance older adults’ access to such information. %M 19917549 %R 10.2196/jmir.1220 %U //www.mybigtv.com/2009/4/e45/ %U https://doi.org/10.2196/jmir.1220 %U http://www.ncbi.nlm.nih.gov/pubmed/ 19917549
