Abstract:Measuring risk-taking has been challenging because of the wide variety of behaviours considered risky. Self-report is one way to measure risk-taking behaviours, but the limitation is the possibility of individuals not answering truthfully. Lejuez et al. (2002) developed a computer-based Balloon Analogue Risk Task (BART) to address self-report limitations. BART is significantly correlated to risk-related constructs such as sensation seeking and impulsivity, as well as risky behaviours such as drug and cigarette consumption. However, the BART limitation is that the two-dimensional task does not have high fidelity and immersion, which leads to the participant's awareness being tested. Thus, a modification that increases fidelity and immersion is needed to measure risk-taking. Therefore, this study aims to replicate and validate the original study of BART by Lejuez et al. (2002) in virtual reality (VR). Moreover, VR technology can reduce negative user experiences. The expectation in replicating BART to VR is that the tool is positively correlated with risk-related constructs. The design is within subjects where the participants performed both conditions (Computer Based (CB) and VR versions) and filled in risk-related questionnaires used in the original study. The result shows positive correlation between VR version BART with risk-related constructs, no difference in participants' performance between CB and VR versions, the VR version has higher immersion than CB version, and satisfying as a tool. In conclusion, the VR version of BART still needs further study with more variety of samples and the VR version of BART is an acceptable tool for measuring risk-taking.
