Relapse-Prevention Support from a Virtual  Coach to Quit Smoking: a Virtual Reality Study

Mobile applications with a virtual coach providing real-time relapse-prevention support may be useful to aid smoking cessation as they are easily accessible, cost-effective, and can be utilized directly in situations where the risk of relapse is high. This study aimed to examine the effect of three types of relapse-prevention support on tobacco craving to inform the development of a mobile application with a virtual coach. The three types of support focused on (A) motivation and self-efficacy; (B) one’s future self and implementation intentions; and (C) identity-related positive self-talk. Secondly, the study aimed to explore how physical nicotine dependence related to the effect of relapse-prevention support on tobacco craving. A virtual reality experiment with a within-participant design was conducted where 25 participants intending to quit smoking were immersed in a virtual high-risk-of-smoking environment. The participants had four conversations in a randomized order with a...Show moreMobile applications with a virtual coach providing real-time relapse-prevention support may be useful to aid smoking cessation as they are easily accessible, cost-effective, and can be utilized directly in situations where the risk of relapse is high.

Secondly, the study aimed to explore how physical nicotine dependence related to the effect of relapse-prevention support on tobacco craving. A virtual reality experiment with a within-participant design was conducted where 25 participants intending to quit smoking were immersed in a virtual high-risk-of-smoking environment. The participants had four conversations in a randomized order with a concept version of a virtual coach on a simulated mobile phone: three conversations containing a type of relapse-prevention support and one neutral conversation. Physical nicotine dependence was measured at baseline and craving was measured after each conversation. Participants indicated that they would find it reasonably difficult to refrain from smoking in the VR environment and sense of presence was sufficient. Results indicated that the relapse-prevention support did not decrease craving compared to neutral contact with the coach. Furthermore, no association was found between physical nicotine dependence and effect of relapse-prevention support. These results stress the need for evaluations of effectiveness in order to inform the further development and improvement of the relapse prevention support prior to finalizing a mobile application with a virtual coach.Show less
