The Australian Research Council funded this survey through providing a scholarship as part of the grant to reduce health disparities in culturally and linguistically diverse populations, regarding HIV, sexually transmissible infections and blood-borne viruses.

Brief Overview

Among people living with hepatitis B virus (HBV) infection in Australia, 38% are from culturally and linguistically diverse (CaLD) groups born in North-East and South-East Asia. Gaps exist in the available information related to HBV knowledge, attitudes and practices (KAP) in these populations. The surveys focussed on HBV KAP in these populations used face-to-face interview and self-administered paper survey. These strategies are associated with challenges, for example, social desirability bias, interviewer bias, cost/time for translation and interpretation, spoken-only languages, translation quality, and variable literacy levels. These barriers could be overcome by the use of audio records and pictures.

The current study will develop an audio computer-assisted self-interview (ACASI) survey tool with pictures illustrating survey questions and response options, and assess the acceptability of this mode of administration by the population which uses several languages, and of which a proportion has language barrier or limited literacy. The hepatitis B knowledge, attitudes and practices survey will be administered among the people born in Myanmar and living in Perth by three modes of administration, including ACASI with illustrated pictures. The quantity and quality of data obtained by ACASI with pictures will be compared to those obtained by face-to-face interviews or self-administered paper surveys.

Project objectives

  • To adapt a survey questionnaire used in previous surveys which assessed knowledge, attitudes and practices of hepatitis B transmission and prevention
  • To test the face validity of the survey questionnaire with a subset of the target population
  • To develop audio-visual aids based on the revised questionnaire
  • To review the audio-visual aids with a subset of the target population
  • To build an audio computer-assisted self-interview (ACASI) survey tool with illustrated pictures
  • To test user acceptance of the ACASI tool with illustrated pictures with a subset of the target population
  • To document the process of developing the ACASI survey tool with illustrated pictures, including lessons learned
  • To administer a hepatitis B KAP survey among Myanmar community in Perth by three modes of administration: (i) ACASI with illustrated pictures, (ii) face-to-face interviews, and (iii) self-administered paper surveys
  • To compare single-item completion rates of sensitive and non-sensitive questions, and quality of responses to sensitive questions between data collected by an ACASI survey tool with illustrated pictures and data collected by face-to-face interviews or self-administered paper survey

Project Impacts

The findings will add more evidence to the literature around comparison of modes of survey administration, specifically for migrants and surveys of sensitive issues. The findings will suggest the mode(s) of administration enabling people with limited literacy and language barriers to take part in surveys of socially discriminable behaviours. The findings will inform whether migrants with limited literacy or who use different dialects can take part in the ACASI survey with audio tracks in most commonly used languages in source and receiving countries, complemented with pictures. The study will contribute to the engagement of vulnerable populations in public health research.
