Research on the health care behavior of older adults in response to symptoms will benefit from having data collection methods that can monitor health actions as they occur on a daily basis. In the present study, symptom experiences over a 2-week period and the actions taken in response to them were studied with a self-kept daily diary. Participants were 142 community-resident older persons, aged 62-94. Diary information about number of daily symptoms and the accompanying pain/discomfort was correlated with health perceptions and psychosocial indices obtained in an interview prior to the diary period. Women tended to take a more active response to symptoms than men, particularly in the area of personal care actions. Preventive health behaviors were not strongly related to symptom-related actions. Satisfaction with one's income was the only predictor of seeking professional assistance. Overall, the diary method is feasible to use with older adults, although certain groups may require special consideration (e.g., the visually impaired, persons with multiple symptoms per day, or those with a limitation on writing ability).
