Natasha Jackson described the GSMA’s recent collaboration with the Mobile Society Research Institute as it surveyed over 20,000 children and their parents in 13 countries about their mobile phone use, most recently in Iraq, Saudi, Egypt and Algeria. Each study involves paired research, usually interviewing parents and children together. Participants are asked questions such as how mobiles were acquired, what the children use them for, what parents think about risks and what risks the children encountered. Some variation in the methodology is allowed – for example, online, face-to-face – but there is a core set of questions that every country has to ask, including a minimal set of questions on mobile risk. Usually the national mobile operator pays for the research. GSMA’s large evidence base is attractive to policymakers, especially in countries where children’s internet use is gaining policy attention. Jackson outlined the challenges of multistakeholder engagement, which include: • Countries’ reasons for participating vary hugely – depending on the national operator, or if the operator wishes to target the child or teen market, or to launch a new service. • The purpose of comparative research – operators don’t want to stand out, especially regarding evidence of problems with their services, and so prefer a comparative report rather than the spotlight on one country. • Research lead time – researchers must talk to the operator/sponsor in the year before the budget, which itself is a year before publishing the report. • The budget may be commercial, CSR, marketing, etc. – it comes from different places and requires different rationales. • The operator often wants a tangible deliverable, for example, a national launch in addition to a comparative report. • Messaging around risk is particularly difficult to manage.
