The Immersive Virtual Reality Assay (IVRA) is a virtual reality paradigm designed to engage three self-regulation targets (self-focused reflection, affect, and cognition) and four corresponding brain circuits in a fixed order: (1) default mode circuit (related to self-focused reflection), (2) the negative affect circuit, (3) the positive affect circuit, and (4) the cognitive control circuit. Participants undergo different virtual environments using the Oculus Rift DK2 (virtual reality headset developed and manufactured by Oculus VR). The self-regulation targets listed above are assessed behaviorally and via self-report. This paradigm is intended to assess a participant’s regulation of self-reflection. This virtual reality environment is used to engage the default mode circuit (regions in the anterior medial prefrontal cortex, anterior gyrus, and posterior cingulate cortex). The paradigm also intends to acclimate the participant to virtual reality environments by displaying natural and relaxing settings as 360-degree still images to minimize sensory stimulation and instead engage self-reflective processes. At follow-up visits, experimenter should allow participants to choose one of two baseline environments to ensure preference and consequent relaxing effects. For behavioral assessment, participants’ behavior is videotaped and then coded via FRAPS screen capture software on the virtual reality headset (FRAPS, 2016). The headset’s coordinates in space relative to the origin as well as its three-dimensional movements (i.e., pitch, yaw, and roll) are also captured over the duration of each environment. At the end of each virtual environment experience, participants are given a self-report form to report the intensity of their emotions across the following scales: amusement, anger, confusion, contempt, disgust, fear, happiness, pain, relief, sadness, tension, relaxation, nausea/discomfort, and strength of immersion. Additionally, participants’ motion sickness is also monitored via self-report.
The Immersive Virtual Reality Assay (IVRA) was created to engage self-regulation targets to elucidate mechanisms of change implicated in depression and obesity. Deficient self-regulation ability is associated with an array of maladaptive behaviors and consequences (e.g., overeating, inactivity, and psychopathology). Alternatively, improved weight management, mental health, and social interactions are outcomes of those who display more aptitude at regulating their self (Gross & John, 2003; Tangney, Baumeister, & Boone, 2004; Gillison et al., 2015). Self-focused Reflection (a target of self-regulation) may be imperative in evaluating social-emotional situations and achieving future goals (Immordino-Yang, Christodoulou, & Singh, 2012), and can thus be a potential determinant in behavior change.

The Science of Behavior Change (SOBC) program seeks to promote basic research on the initiation, personalization and maintenance of behavior change. By integrating work across disciplines, this effort will lead to an improved understanding of the underlying principles of behavior change. The SOBC program aims to implement a mechanisms-focused, experimental medicine approach to behavior change research and to develop the tools required to implement such an approach. The experimental medicine approach involves: identifying an intervention target, developing measures to permit verification of the target, engaging the target through experimentation or intervention, and testing the degree to which target engagement produces the desired behavior change.
Within the SOBC Measures Repository, researchers have access to measures of mechanistic targets that have been (or are in the processing of being) validated by SOBC Research Network Members and other experts in the field. The SOBC Validation Process includes three important stages of evaluation for each proposed measure: Identification, Measurement, and Influence.
The first stage of validation requires a measure to be Identified within the field; there must be theoretical support for the specific measure of the proposed mechanistic target or potential mechanism of behavior change. This evidence may include references for the proposed measure, or theoretical support for the construct that the proposed measure is intended to assess. The second stage of validation requires demonstration that the level and change in level of the chosen mechanistic target can be Measured with the proposed measure (assay). For example, if the proposed measure is a questionnaire, the score on the measure should indicate the activity of the target process, and it must have strong psychometric properties. The third stage of validation requires demonstration that the measure can be Influenced; there must be evidence that the measured target is malleable and responsive to manipulation. Evidence relating to each stage includes at least one peer-reviewed publication or original data presentation (if no peer-reviewed research is available to support the claim) and is evaluated by SOBC Research Network Members and experts in the field.
Once a measure has gone through these three stages, it will then either be Validated or Not validated according to SOBC Research Network standards. If a measure is Validated, then change in the measured target was reliably associated with Behavior Change. If a measure is Not validated, then change in the measured target was not reliably associated with Behavior Change. Why would we share measures that are not validated? The SOBC Research Network values open, rigorous, and transparent research. Our goal is to make meaningful progress and develop replicable and effective interventions in behavior change science. Therefore, the SOBC sees value in providing other researchers in the field with information regarding measures that work and measures that fall short for specific targets. Further, a measure that is not validated for one target in one population may be validated in another target or population.
