ABSTRACT

INTRODUCTION: Globally, population surveys on HIV/AIDS and other sensitive topics have been using audio computer-assisted self interview for many years. This interview technique, however, is still new to Vietnam and little is known about its application and impact in general population surveys. One plausible hypothesis is that residents of Vietnam interviewed using this technique may provide a higher response rate and be more willing to reveal their true behaviors than if interviewed with traditional methods. OBJECTIVE: This study aims to compare audio computer-assisted self interview with traditional face-to-face personal interview and self-administered interview with regard to rates of refusal and affirmative responses to questions on sensitive topics related to HIV/AIDS. METHODS: In June 2010, a randomized study was conducted in three cities (Ha Noi, Da Nan and Can Tho), using a sample of 4049 residents aged 15 to 49 years. Respondents were randomly assigned to one of three interviewing methods: audio computer-assisted self interview, personal face-to-face interview, and self-administered paper interview. Instead of providing answers directly to interviewer questions as with traditional methods, audio computer-assisted self-interview respondents read the questions displayed on a laptop screen, while listening to the questions through audio headphones, then entered responses using a laptop keyboard. A MySQL database was used for data management and SPSS statistical package version 18 used for data analysis with bivariate and multivariate statistical techniques. Rates of high risk behaviors and mean values of continuous variables were compared for the three data collection methods. RESULTS: Audio computer-assisted self interview showed advantages over comparison techniques, achieving lower refusal rates and reporting higher prevalence of some sensitive and risk behaviors (perhaps indication of more truthful answers). Premarital sex was reported by 20.4% in the audio computer-assisted self-interview survey group, versus 11.4% in the face-to-face group and 11.1% in the self-administered paper questionnaire group. The pattern was consistent for both male and female respondents and in both urban and rural settings. Men in the audio computer-assisted self-interview group also reported higher levels of high-risk sexual behavior--such as sex with sex workers and a higher average number of sexual partners--than did women in the same group. Importantly, item refusal rates on sensitive topics tended to be lower with audio computer-assisted self interview than with the other two methods. CONCLUSIONS: Combined with existing data from other countries and previous studies in Vietnam, these findings suggest that researchers should consider using audio computer-assisted self interview for future studies of sensitive and stigmatized topics, especially for men.

ABSTRACT

INTRODUCTION: Violent acts in young people constitute one of the most serious forms of violence in any society. Violence by young people in schools, on the streets, and in their families has been documented in many studies worldwide. Homicide and non-fatal assaults involving young people have been reported as a great global burden of premature death, injury and disability. Adolescents and young people are both the main victims and perpetrators of such violence. In Vietnam, an emerging pattern of health problems in adolescents related to intentional injury and violence is drawing increasingly more attention from government and the public. OBJECTIVE: Describe the situation of intentional injury among Vietnamese youth, including risk and protective factors, in order to suggest policy implications. METHODS: The 2003 Survey Assessment of Vietnamese Youth was used as a data source, providing a nationally representative sample of 7584 youth aged 14-25 years, resident in 42 of the country's 61 provinces. This sample was drawn from the 45,000 households in the 2002 Vietnam Living Standards Survey, with a multi-staged and stratified design, using the probability-proportional-to-size method to maintain representativity. Data were analyzed using bivariate and multivariate statistical techniques. RESULTS: Of the sample of young people, 2.2% reported injury resulting from violent behavior by a family member and 8.0% by non-family members, the latter demonstrating a significantly higher rate among males than females (13.6% vs. 2.4%). Characteristics of youth most likely to hurt others included: male sex, inebriation at some point, victims of intentional injury, group riot participants and carriers of weapons. Youth who had been members of mass social organizations or clubs in the community were half as likely to hurt other people as those who were unaffiliated with such groups. Females were almost four times more likely than males to attempt suicide. Other risk factors for suicide attempts were past inebriation (OR 2.7, 95% CI 1.3-5.4), ever having been a victim of intentional injury by a family member (OR 3.3, 95% CI 1.1-11.5) or ever having had feelings of hopelessness (OR 6.5, 95% CI 3.3-13.6). CONCLUSIONS: Prevalence of violence and self-harm among Vietnamese youth is comparatively less than in Western and other Asian countries. Risk and protective factors appear similar to those found in most populations. In particular, this study indicated a possible protective effect of membership in social groups. National policy for injury prevention should include strategies to reduce violence and self-harm within this population group.
