Brief Summary
Anhedonia is a symptom dimension that characterizes many individuals suffering from depression, as well as some types of anxiety, psychosis, and substance use. For the most part, treatments are effective in decreasing negative affect but ineffective in improving anhedonia, with some antidepressant medications even worsening symptoms of anhedonia. Yet anhedonia is a significant marker of poor prognosis as well as suicidal ideation and actual suicide. The development of effective treatments for anhedonia is thus of paramount importance. Advances in neuroscience indicate specific targets that may underlie anhedonia that can be shifted through behavioral training. The investigators have developed such a program and found it to be effective in raising positive affect, especially for depressed or anxious individuals with anhedonia at baseline. To date, this program has been implemented by highly trained clinicians, which have supervised its implementation on a large scale. Moreover, the behavior program is dependent on readily available rewarding experiences, which anhedonia obviously challenges. Furthermore, mechanistic evaluation is impeded by intra¬- and inter-¬individual variability in exposure to rewarding stimuli. Virtual Reality (VR) offsets these barriers by repeated controlled immersion in experiences designed to enhance approach motivation, initial responsiveness to reward attainment, and reward learning. In this current study, the investigators aim to measure clinical outcomes using Virtual Reality-Reward Training (VR-RT).

Outcome Measures
Primary Outcomes (1)
Change in anhedonia
Change in anhedonia as measured by the anhedonia subscale of the Mood and Anxiety Symptom Questionnaire (MASQ) (max: 110, min: 22, with a higher score indicating higher anhedonia)
Baseline to Post-treatment (4 weeks)
Study Arms (2)
Control
NO INTERVENTIONThe control group will not undergo the positive virtual reality training program. Instead, they will complete all self-report and behavioral measures and have the option to experience the positive virtual reality training program upon the conclusion of the study.
Positive Virtual Reality Training Intervention
EXPERIMENTALThe experimental group will undergo the positive virtual reality training program, which consists of 7 virtual reality (VR) sessions to be completed at home after orientation to the program, in addition to all self-report and behavioral measures.
Interventions
Participants will undergo 7 45 minute sessions of positive virtual reality training over the course of four weeks. All assessments will be completed online at home following initial orientation to the program.
