  1. Measuring Behavioural Outcomes with Polling Booth Surveys B.M. Ramesh, PhD Department of Community Health Sciences, University of Manitoba, Winnipeg, Canada & Karnataka Health Promotion Trust, Bangalore, India

  2. Background • Focused HIV prevention program in 6 high prevalence states in India • KSAPS implementing the program in 9 districts of Karnataka • KHPT implementing the program in 16 districts in Karnataka and 3 districts in Maharashtra. • Main objective is to reduce the incidence of HIV and STIs. • Monitor changes in condom use and other sexual behaviours • Polling Booth Surveys (PBS) among FSWs

  3. What is polling booth survey? • Polling booth survey is: • A group interview method • Where the individuals give their responses through a ballot box • Where the individual responses are anonymous and unlinked

  4. Polling booth survey: Advantages • More suitable to collect information on sensitive and personal issues • Reduces social desirability bias • Respondent remains anonymous • Easy to administer among the illiterate • Increases sense of confidentiality among participants • Simple to analyze • Not individualized face to face interview, but a group approach using a moderator giving instructions

  5. Comparison of face-to-face interviews with PBS • Among FSWs • The FTFI tends to overestimate the condom use behaviour • The PBS tends to minimize the exaggeration of reported condom use • Among the general population • The FTFI tends to underestimate the risky sexual behaviours • The PBS tends to give a relatively higher reporting of risky sexual behaviours

  6. Comparison of FTFI and PBS for eliciting sensitive behaviours among unmarried subjects in Mysore GPS *Among those who have heard of HIV/AIDS

  7. Comparison of FTFI and PBS for eliciting sensitive behaviours among married subjects in Mysore GPS  *Among those who have heard of HIV/AIDS

  8. Comparison of FTFI and PBS for eliciting sensitive behaviours among unmarried subjects in Belgaum *Among those who have heard of HIV/AIDS

  9. Comparison of FTFI and PBS for eliciting sensitive behaviours among married subjects in the Belgaum *:Among those who have heard of HIV/AIDS

  10. PBS methods (1) • Members are separated from each other in a polling booth environment • Each participant is given 3 boxes (Red, Green and White) and a pack of cards • Cards are numbered corresponding to the number of questions asked • Cards are stacked in serial order • Responses • Card with the number corresponding to the question asked is put into the Green box if the response to the question is YES • Card is put into the Red box if the response is NO • Card is put into the White box if the question is NOT APPLICABLE • Card is kept outside these boxes if the participant does not want to respond to that question

  11. PBS Method (2) • The moderator explains the PBS method with an example and a practice session • Questions are read one by one • The moderator needs to • Make the exercise lively • Ask each question clearly, slowly and loudly so that every participant hears the question clearly, repeating the question as required • Use situations/stories while asking the question • Use local terms • Give sufficient pause, and not to hurry

  12. PBS Method (3) • At the end of administering the questions: • Collect the cards separately: the ones that are in the Green boxes, the ones that are in Red boxes and the ones that are in the White boxes • Count the number of cards in each box for each question and record the tallies in the reporting form • Share and discuss the group responses with the participants • Document group discussion points

  13. Sampling in PBS • The subjects for the PBS may be recruited using any of the probability sampling methods

  14. Polling booth questions • Only the questions that have a definitive YES or NO as answers are suitable to be canvassed in PBS • How often do you use condoms with your regular clients? (Not suitable for PBS)

  15. Challenges/Limitations • Non-response could be higher as not all selected individuals are able to participate in a group at the designated time and place • Can include only the questions that have a YES or NO answers • Can ask only a limited number of questions – questionnaire cannot be as long as the one that could be used in a face-to-face interview • Can get only the group-aggregated data, and cannot be analyzed with linkages to individual characteristics
