Researchers at Cornell University are using smartphones to capture location and real-time survey data to examine how social environments encountered in everyday life may affect health.
Equipped with smartphones for a week, dozens of older New York City residents allowed a Cornell sociologist to track their movements and reported several times a day where they were, what they were doing and how they felt.
The 61 study participants, all age 55 or older, shared glimpses of their daily routines and activities: working at a bakery, being at home with a cat, walking in a park with grandchildren, visiting with friends, waiting in line for coffee and going to church. They also noted when they saw litter, vacant buildings, damaged sidewalks and other scenes they considered problematic, such as evidence of drug or alcohol use.
In the places they perceived as stressful or threatening, the older adults were significantly more likely to report momentary spikes in fatigue or pain, the study found. When observing at least two of those disorderly conditions, they were twice as likely to report feeling tired and about two-thirds more likely to report feeling pain.
“These fluctuations may have longer-term impacts on health and well-being for older adults who have to navigate demanding or distressing social environments on a regular basis,” said Erin York Cornwell, lead author of the study.
In New York City, York Cornwell worked with community-based senior centers to recruit a diverse group of volunteers from four neighborhoods: East Harlem, Gramercy and the north and south sections of Bedford-Stuyvesant.
On average, about one-third of the study participants reported feeling some pain and about one-third some fatigue in any given survey, with those feelings being less prevalent in more orderly spaces. The risk increased with each additional condition of disorder observed.
The participants completed most of the surveys within 10 or 15 minutes of being pinged on their smartphones to complete one. Their overall response rate of nearly 99% is almost unheard of in survey research, York Cornwell said.
Researchers typically have relied on survey respondents to keep paper logs of their experiences, often recorded long after events occurred. Though still an emerging research method, York Cornwell said, smartphone-based data collection enables more immediate responses that promise to improve survey accuracy and reduce bias.
“It’s an incredible tool for understanding how people experience and perceive their environments in real time, and then looking at how those environments may affect their health,” she said. “We haven’t been able to get that insight in such a clean way in the past, so this approach has really exciting implications.”
