The non-verbal response card was developed and tested as part of the Gilgel Gibe Social and Sexual Relationship History Survey 2006. Results of a comparison of the card method with conventional verbal response methods have been published in articles appearing in Studies in Family Planning (2010) and Journal of Adolescent Health (2012).
The non-verbal response cards were used for sensitive questions regarding sexual knowledge, attitudes and practices in the second, third and fourth rounds of the Adolescent Surveys as part of the Jimma Longitudinal Family Survey of Youth. The non-verbal cards provide a confidential and private (non-verbal) method for respondents to provide answers to questions that are subject to social desirability bias in the context of a face-to-face interviewer administered survey. A full description of the cards is provided in the JLFSY Study Design guide that can be accessed via the link below.

In the fourth round survey the an experimental test was conducted comparing the non-verbal response card to a new experimental touch card. The touch card was designed to reduce error associated with the non-verbal response card and more easily allow skip patterns. To use the touch card, respondents point to their response in full-view of the interviewer and the interviewer records the response. The touch card allows the respondent to non-verbally respond to sensitive questions. Although the response is known by the interviewer, the touch card does provide an enhanced level of privacy compared to the conventional verbal response method.
