Evaluation of a Novel Intervention Aimed at Instilling Future-oriented Mindsets and Behaviors Using a Smartphone Application and Immersive Virtual Reality

People with a short-term mindset tend be focused on the here-and-now and are inclined to disregard the more distant consequences of their actions. This often results in self-defeating behaviors, i.e., behaviors that provide immediate gains but that may simultaneously incur significant costs in the longer run (e.g., substance use, delinquency, overspending). In contrast, people who are more future-oriented typically balance the immediate gains against the longer-term consequences of their decisions and are more inclined to set goals for the future. The investigators are developing an intervention, FutureU, aiming to promote future-oriented mindsets and behaviors by strengthening people's identification with their 'future self'. The level of identification with the future self depends on the extent to which people are able to vividly imagine their future self (i.e., vividness), feel positively towards their future self (i.e., valence), and feel similar and connected to their future self (i.e., related). During the intervention, participants interact with their future self. This future self is developed on the basis of a digitally aged image of themselves. In order to present the visual representation of the participants' future self, the investigators implement the intervention via a smartphone application (app) and via immersive virtual reality (VR). The present study examines the current iteration of the FutureU intervention, which is developed within an ongoing research program. The findings of this study will be used to further develop and optimize the FutureU intervention.

In a three-armed Randomized Controlled Trial, the investigators will evaluate the FutureU intervention by examining 1) its effectiveness on both proximal and distal outcomes, 2) its working mechanisms, and 3) moderators of intervention effects. It is hypothesized that FutureU will increase participants' future-oriented mindsets and behaviors (e.g., increase future orientation, enhance goal achievement, and reduce self-defeating behaviors). There are no specific expectations regarding differences in effectiveness between the two implementation strategies (app vs. VR). Regarding the working mechanisms, the hypothesis is that intervention effects of FutureU are mediated by increases in future self-identification. Concerning moderators, the investigators will examine the moderating role of personality traits within an intervention context in an exploratory fashion. Furthermore, associations between usage patterns (e.g., length and frequency of use), engagement levels and intervention outcomes will be examined, and the goals set by the participants will be analyzed qualitatively and quantitatively.
