Nominative technique, a simple tool for assessing illegal wildlife consumption
To test the efficacy of nominative technique within a small sample, we performed a total of 179 semi-structured interviews in Luang Prabang, northern Laos, in August 2017 and April 2019, using the domestic consumption of bears in northern Lao People’s Democratic Republic (hereafter Laos) as our case study. We also assessed whether the specialised questioning technique of nominative technique could be used within qualitative data collection methods, such as semi-structured interviews. The technique theoretically ensures more accurate statements of illegal wildlife consumption behaviour, by maintaining the anonymity of an individual’s sensitive behaviour through asking about the behaviour of peers. We also directly asked about participants’ use of bear bile. Nominative technique showed that approximately 11% of the participants’ peers used bear products, with respondents’ direct admittance of using bear bile was nearly double, at 23%. Use of bear parts appears to not be sensitive in northern Laos. In addition, a strong association was found between nominative technique and direct questioning responses, which indicates that users of bear parts have social networks with higher levels of use. This lends supports to theories that use of wildlife products is directly influenced by the social group. The underreporting found through nominative technique indicates the high variability of response that can occur within small samples; however, these results show that nominative technique may be a simple, useful tool for triangulating data, assessing users’ integration into social networks of use, and assessing changes in behaviour prevalence.
