Research Background

In January 2015, Hong Kong Practicing Specialist Association and Hong Kong Men's Health Society commissioned the Public Opinion Programme (POP) of The University of Hong Kong to conduct this “Survey on Complications of Cold and Flu” targeting Cantonese-speaking Hong Kong citizens aged 50 or above. The objectives of the survey were to understand how senior citizens in Hong Kong usually dealt with the symptoms of cold and flu and to gauge their awareness of the complications of cold and flu.

The research instrument used in this study was designed entirely by the POP Team after consulting Hong Kong Practicing Specialist Association and Hong Kong Men's Health Society, while all parties 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.

Survey date	:	4-13/5/2015
Target population	:	Cantonese-speaking Hong Kong citizens aged 50 or above
Survey method	:	Random telephone survey conducted by real interviewers
Sampling method	:	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. If more than one eligible subject had been available, the one who had his/her birthday next was selected.
Sample size	:	507 successful cases
Effective response rate	:	75.4%
Standard error	:	Less than 2.2% (i.e. at 95% confidence level, the maximum sampling error of all percentages should be no more than +/-4.4 percentage points)

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 50 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 May 4 to 13, 2015. A total of 507 respondents were successfully interviewed. The effective response rate of this survey was 75.4%, 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 4.4 percentage points at 95% confidence level.
