Assessing Concerns about Falling: A Comparison of Telephone-Based and In-Person FES-I Interviews in Older Adults
While telephone-based FES-I interviews show good agreement with face-to-face assessments for group-level comparisons in older adults, they yield significantly lower scores and are not equivalent for individual clinical decisions, particularly due to age-related differences and specific item variations.

Imagine you are trying to measure how much a group of seniors worries about falling down. To do this, researchers use a specific "worry thermometer" called the FES-I. This tool asks 16 questions about everyday activities, like "How worried are you about falling while taking a shower?" or "How worried are you about falling while answering the phone?"
The researchers wanted to know: Does it matter if you ask these questions over the phone or in person?
Think of it like trying to guess the temperature of a room. You can either stick your hand in the doorway (telephone) or walk inside and stand right next to the heater (face-to-face). Do you get the same reading?
Here is what the study found, broken down simply:
1. The "Phone vs. Room" Difference
The researchers asked the same 123 seniors (all aged 70+) the same questions twice: once over the phone and once in person.
- The Result: When asked over the phone, the seniors said they were less worried about falling than when asked in person.
- The Analogy: It's like asking someone, "How scared are you of spiders?" If you ask them while they are holding a picture of a spider (in person), they might say, "Very!" But if you ask them while they are looking out a window at a garden (on the phone), they might say, "Not so much." The phone interview seemed to make the worry feel a little less "real" or intense.
2. The "Group" vs. "Individual" Rule
The study found that while the phone answers were slightly lower, they still followed the same general pattern as the in-person answers.
- The Analogy: Imagine a choir. If you listen to the choir over a bad radio connection (phone), the volume might be slightly lower, but you can still tell if the choir is singing loudly or softly as a group.
- The Claim: The phone method is okay for looking at big groups (like saying, "On average, this neighborhood is worried"). However, it is not reliable for judging one specific person. If a doctor needs to decide if one specific senior needs help, the phone interview might underestimate their fear, leading to a wrong decision.
3. The "Age" Factor
The study discovered that the older the person was, the bigger the gap became between the phone answer and the in-person answer.
- The Analogy: Think of the phone as a pair of glasses that are slightly foggy. For a younger person, the fog is thin, and they can see clearly. For an older person, the fog is thicker, and the picture gets blurrier. As people got older (closer to 80+), the phone interview became a less accurate way to measure their true feelings.
4. The "Shower" and "Phone" Exceptions
Two specific questions stood out as being very different depending on how they were asked:
- Taking a shower/bath: People said they were less worried about this on the phone.
- Answering the phone: People said they were less worried about this on the phone.
- The Analogy:
- The Shower: Talking about a shower over the phone feels abstract. You aren't standing on the wet tile. In person, the interviewer might be able to see the person's body language or hesitation, making the fear feel more real.
- The Phone: It's a bit ironic! When asked "Are you worried about falling while answering the phone?" over the phone, people might have thought, "Well, I'm doing it right now, and I'm fine!" In person, they might have visualized the rush to get to the ringing phone and remembered how dangerous that rush could be.
The Bottom Line
The paper concludes that telephone interviews are a useful tool for large surveys (like checking the mood of a whole city), but they are not a perfect substitute for talking face-to-face when you need to make a decision about a single person's health.
The researchers suggest that because older adults might "downplay" their worries over the phone, doctors and researchers should be careful. If they are making a plan to help one specific person, they should probably sit down with them in the same room to get the truest reading of their fears.
