Abstract: Abstract of thesis entitled Mobile Phone Surveys in Hong Kong: Methodological Issues and Comparisons with Conventional Phone Surveys Submitted by Lau Ka Po for the degree of Master of Philosophy at The University of Hong Kong in May 2005 In Hong Kong, in 2003, there were households which were not equipped with conventional phones for the first time. On the other hand, at the end of 2003, mobile penetration rate was 100%. The mobile penetration in Hong Kong is very high which makes a mobile phone survey generally feasible and also, some households nowadays are not equipped with conventional phones which makes a mobile phone survey important to see if it can capture this sub-population. The current research aimed at examining and comparing methodological issues and survey results of a mobile survey and its corresponding fixed line component. Random digit dialing with stratification on mobile network operators and digital networks was adopted for sampling in the mobile component which was deemed effective in terms of response rates. The final disposition codes used for traditional fixed line surveys were also adapted for the mobile component which also seemed feasible as no apparent problems were found in call outcome classifications. The success rates of the mobile and fixed line components were 50% and 47% respectively. The mean interview lengths per question of the two components were not significantly different. The two components of the current study have covered respondents with different demographic characteristics. The mobile component included higher percentages of respondent who were working or unemployed, males, with upper secondary education or above, aged younger than 45, and never married or divorced/separated while the fixed line component had higher percentages of respondents who were students, homemakers, the retired, females, with lower secondary education or below, aged 45 or older, and married or widowed. Respondents of the two components also had different patterns of phone use and they were not equally available for mobile phone surveys and conventional surveys. 1 For the mobile component, 82% of the respondents who completed the whole interview were willing to talk using a mobile phone without diverting the call to a fixed line telephone for about 18 minutes on average. 16% of them did not have a fixed line telephone at home. The 'mobile only' group also has some distinct characteristics when compared with the fixed line component. This 'mobile only' group was distinctively different from the participants in a traditional telephone survey by its inclusion of a much higher percentage of respondents who were unemployed. Conventional telephone survey results may under represent the unemployed. Since survey outcomes may depend on variables other than interview phone types such as survey topics, organizations initiating a particular survey, question types, and length, more mobile surveys from different settings on different topics are needed to generate a comprehensive picture in mobile survey practice.
