Model 900, 1800 MHz (GSM) mobile phone use in teenagers

Teenage volunteers (n=90, age 11-16) were questioned regarding mobile phone use via recording 24-hr activity diaries and focus groups. Interviews to re-affirm diary records did not improve the accuracy of recall. Mobile phones were used more by the older children and on average slightly more by the girls than the boys. The number of calls and text messages seemed mostly governed by the user's budget, and were often very short (10-20 seconds). Those sending fewer texts made more mobile phone calls. Boys used the phone more as a game console and girls used the phone more as a mobile and computer. Phone use was influenced by whether the teen had a boy- or girlfriend, and whether they dated or traveled by public transport to school. School days vs. other days and school rules also influenced use, and use increased with age. Taking / sending pictures and use as a game console was popular. Use on the internet was of little or no interest, probably due to limitations in bandwidth causing long delays. The range of use (from high to low) was from not at all to 45 times in the day.
