Abstract

Potential differential and non‐differential recall error in mobile phone use(MPU) in the multinational MOBI‐Kids case–control study were evaluated.We compared self‐reported MPU with network operator billing record data up to 3 months, 1 year, and 2 years before the interview date from 702subjects aged between 10 and 24 years in eight countries. Spearman rankcorrelations, Kappa coefficients and geometric mean ratios (GMRs) wereused. No material differences in MPU recall estimates between cases andcontrols were observed. The Spearman rank correlation coefficientsbetween self‐reported and recorded MPU in the most recent 3 monthswere 0.57 and 0.59 for call number and for call duration, respectively. Thenumber of calls was on average underestimated by the participants(GMR = 0.69), while the duration of calls was overestimated (GMR = 1.59).Country, years since start of using a mobile phone, age at time of interview,and sex did not appear to influence recall accuracy for either call number orcall duration. A trend in recall error was seen with level of self‐reportedMPU, with underestimation of use at lower levels and overestimation of useat higher levels for both number and duration of calls. Although bothsystematic and random errors in self‐reported MPU among participantswere observed, there was no evidence of differential recall error betweencases and controls. Nonetheless, these sources of exposure measurementerror warrant consideration in interpretation of the MOBI‐Kids case–controlstudy results on the association between children's use of mobile phonesand potential brain cancer risk.
