Validation of self-reported cellular phone use.

View Original AbstractPeople significantly underestimate their actual cell phone usage, making most health studies less reliable than they appear.
Plain English Summary
German researchers tested how accurately people remember their cell phone usage by comparing what 68 people reported in surveys to their actual phone records from network providers over three months. They found people were reasonably good at remembering how many calls they made per day (62% accuracy) but much worse at remembering how long each call lasted (34% accuracy). This matters because most cell phone health studies rely on people accurately reporting their usage patterns.
Study Details
In recent years, concern has been raised over possible adverse health effects of cellular telephone use. In epidemiological studies of cancer risk associated with the use of cellular telephones, the validity of self-reported cellular phone use has been problematic. Up to now there is very little information published on this subject.
We conducted a study to validate the questionnaire used in an ongoing international case-control stu...

Our study suggests that cellular phone use is easier to recall in terms of number of calls made than in terms of cumulative phone use and should thus be used as the basis for the dose-response analysis.
