First, participants completed a 90-minute Audio Computer-Assisted Survey Interview (ACASI), which assessed sociodemographic and relationship characteristics, sexual behaviors and condom use, and psychosocial mediators that had sound psychometric properties and had previously been implemented with adult African-American populations.
Interviews lasting 90-120 minutes were conducted using computer-assisted survey interviewing technology on laptop computers.
Thirteen college student interviewers and two supervisors conducted the interviews using a telephone interviewing software package, Computer Assisted Survey Execution System.
The interviewers simultaneously collected and entered data into a password-protected, computer database using CASES (Computer Assisted Survey Execution System).
All members of the household are then interviewed on a range of topics by trained interviewers using computer assisted interviewing.
We undertook a computer assisted telephone interviewing (CATI) survey of the Australian public and a parallel survey of those involved in nanotechnology from the academic, business and government sectors.
At baseline all participants had their weight, height and blood pressure measured, received the National Heart Lung and Blood Institute's Aim for a Healthy Weight brochure, and completed an audio computer assisted self-interview survey which collected data on demographics, health behaviors, mental health and neighborhood characteristics.
Each participating country can choose from these modules and decide on the most practical and cost-effective survey method (i.e., household face-to-face survey, computer assisted telephone interview, or computer assisted personal interview) [ 41].
Study participants were from a larger computer assisted telephone interview (CATI) survey of the Australian public contacted as part of the National Survey of Adult Oral Health (NSAOH), conducted in Australia between 2004 and 2006 [ 31].
