Research Background

In January 2015, Halo Public Relations Ltd commissioned the Public Opinion Programme (POP) of The University of Hong Kong to conduct this “Survey on Sunscreen Product Usage and Awareness of Medicine Registration” targeting Cantonese-speaking Hong Kong citizens aged 18 or above. The objectives of the survey were to understand the general public’s sunscreen product usage and their awareness of medicine registration policies in Hong Kong.

The research instrument used in this study was designed entirely by the POP Team after consulting Halo Public Relations Ltd, while both POP and Halo Public Relations Ltd had equal say in the final instrument. Moreover, fieldwork operations, data collection and data analysis were conducted independently by the POP Team, without interference from any party. In other words, POP was given full autonomy to design and conduct the survey, and POP would take full responsibility for all the findings reported herewith.

If more than one eligible subject had been available, the one who had his/her birthday next was selected.
Sample size	:	503 successful cases

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 population of this survey was Cantonese-speaking Hong Kong citizens aged 18 or above. 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 March 17 to 26, 2015. A total of 503 respondents were successfully interviewed. The response rate of this survey was 66.8%, and the standard sampling error for percentages based on this sample was less than 2.2 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 4.5 percentage points at 95% confidence level.
