Negative communications with health professionals are a stressor to older adults in healthcare settings. In this situation, older adults seek health information on the Internet as alternative information sources and may consider this as having the equivalent value of communicating with a health professional. This study examines the relationship between communications with health professionals and online health information seeking in older adults. This study used the Health Information National Trends Survey, Cycle 3, and included participants (N = 743) aged 65 or older who used the Internet. A multiple logistic regression was employed to examine the association of health professional communication with online health information seeking. Multinomial logistic regression analysis was applied to examine the association between health communications and three types of online health information seeking in older adults. Online health information seeking was significantly associated with negative communications with health professionals. Health communications only predicted online health information seeking by oneself, and females were more likely to search for health information on the Internet than males. The results of this study show that older adults' online health information seeking is an active coping strategy to reduce health risks and improve health promotion in healthcare.
