Abstract
- Searching the internet for health-related information is a complex and dynamic goal-oriented process that ostensibly places demands on executive functions, which are higher-order cognitive abilities that can deteriorate with older age. This study examined the effects of older age on electronic health (eHealth) search behavior and the potential mediating influence of executive functions. Fifty younger adults (≤ 35 years) and 41 older adults (≥50 years) completed naturalistic eHealth search tasks involving fact-finding (Fact Search) and symptom determination (Symptom Search), a neurocognitive battery, and a series of self-report questionnaires. Multiple regression models controlling for potentially confounding psychiatric symptoms, health conditions, literacy, and demographic variables revealed that older adults were slower and less accurate than younger adults on the eHealth Fact Search task, but not on the eHealth Symptom Search task. Executive functions mediated the relationship between age and Fact and Symptom Search accuracy, independent of basic processing speed and attention. Parallel mediation models showed that episodic memory was not an independent mediator of age and search accuracy for either eHealth task once speed/attention and executive functions were included. Older adults can experience difficulty searching the internet for some health-related information, which is at least partly attributable to executive dysfunction. Future studies are needed to determine the benefits of training in the organizational and strategic aspects of internet search for older adults and whether these findings are applicable to clinical populations with executive dysfunction.
