Research Design Telephone interviews were conducted by interviewers under close supervision. All data were collected by our interviewers using a Computer Assisted Telephone Interview (CATI) system invented by the research team which allowed real-time data capture and consolidation. To ensure data quality, on top of on-site supervision, voice recording, screen capturing and camera surveillance were used to monitor the interviewers' performance.
Telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample.
The target of this interview is full time worker of age 15 or above who speak Cantonese, English or Mandarin. If more than one eligible subject had been available, selection was made using the “next birthday rule” which selected the person who had his/her birthday next. The survey was conducted during the period of September 9 to 29, 2015. A total of 1,013 respondents were successfully interviewed. The response rate of this survey was 64.1%, and the standard sampling error for percentages based on this sample was less than 1.6 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 3.1 percentage points at 95% confidence level.
