A Phase 1 interventional study of Virtual Reality-Reward Training (VR-RT) and Virtual Reality-Memory Training (VR-MT) in Positive Affect and Depression, sponsored by University of California, Los Angeles. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-04.

The purpose of this study is to compare the effects of Virtual Reality-Reward Training (VR-RT) with an active control condition, Virtual Reality-Memory Training (VR-MT), on positive affect and other clinical symptoms.
VR-Reward Training is a novel intervention aimed at enhancing savoring of positive experiences among individuals with depression and low positive affect through guided imaginal recounting following immersion in positive VR experiences.
Target enrollment is 80 male and female participants with low positive affect, depression, and impaired functioning, who are at least 18 years old, who will be randomly assigned to 7 weeks of either Virtual Reality-Reward Training (VR-RT) or Virtual Reality-Memory Training (VR-MT). Participants will complete in-person VR sessions, laboratory assessments, self-report questionnaires as part of the study.
The total length of participation is around 3 months.
Anhedonia, or loss of interest and pleasure in usual activities, has been relatively resistant to pharmacological and psychological treatments in the context of anxiety and depression. Newer treatments that focus upon positivity or reward sensitivity have shown promising results.
The purpose of the current randomized controlled trial is to compare the effects of Virtual Reality-Reward Training (VR-RT) with an active control condition, Virtual Reality-Memory Training (VR-MT), on positive affect and other clinical symptoms. Virtual Reality-Reward Training is designed to augment reward sensitivity in individuals with depression and low positive affect. Targets include behavioral, cognitive, and self-report indices of reward anticipation and initial response to reward. Specificity of target engagement is assessed by comparison with Virtual Reality-Memory Training, designed to improve memory.
Targets and clinical outcomes are assessed at baseline (Week 1) and either weekly or at mid-treatment (Week 3), post-treatment (Week 7), and follow-up (Week 12). Statistical models evaluate whether change in outcomes and change in target measures are greater as a result of Virtual Reality-Reward Training compared to Virtual-Reality-Memory Training and whether changes in target measures correlate with changes in outcome measures.
Target enrollment is 80 male and female participants with low positive affect, depression, and impaired functioning, who are at least 18 years old, who will be randomized to Virtual Reality-Reward Training or Virtual-Reality Memory Training, each comprising 7 individual virtual reality training sessions over the course of 7 weeks.
Participants will complete laboratory tests and self-report questionnaires as part of the study. Total length of participation is around 3 months.

Meet all of the following dimensional score cutoffs:
Exclusion Criteria:
7 sessions of positive VR immersion and positive memory specificity training exercises designed to savor rewarding features of immersion followed by memory specificity training exercises to savor rewarding features of autobiographical memory.
Behavioral: Virtual Reality-Reward Training (VR-RT)
7 sessions of neutral VR immersion and neutral memory specificity training exercises, designed to train memory of objective non-emotional stimuli followed by memory exercises to neutral autobiographical memories.
Behavioral: Virtual Reality-Memory Training (VR-MT)
Participants will complete verbal recounting (present-tense, field perspective, positive details) and guided imaginal recounting of positive details for rewarding VR experiences and positive autobiographical memories.
Participants will complete verbal recounting (past-tense, observer perspective, objective details) and guided imaginal recounting of neutral details for neutral VR experiences and neutral autobiographical memories.
Depression, Anxiety, and Stress Scales (DASS-21)
Reported symptoms of depression (score range: 0-21), anxiety (score range: 0-21), and stress (score range: 0-21), higher scores indicate higher severity and frequency.
Time frame: Change from baseline to follow-up (Week 12)
The Positive Affect and Negative Affect Schedule-Expanded Form (PANAS X) (General Dimensions Scales)
Change in reported positive affect (general dimensions scale positive affect) and negative affect (general dimension scale negative affect) (score range for each scale: 10-50, higher scores represent higher levels of positive affect or negative affect).
Time frame: Change from baseline to follow-up (Week 12)
MASQ-AD 14 Item
Change in reported anhedonia (score range: 14-70), with higher scores indicating greater anhedonic symptom severity
Time frame: Change from baseline to follow-up (Week 12)
Behavioral Activation Scale (BAS)
Change in reported reward sensitivity (score range: 23-92), with higher scores indicating higher reward sensitivity
Time frame: Change from baseline to follow-up (Week 12)
Work and Social Functioning Scale (WSAS)
Change in impairment in the following life domains: work (score range: 0-8), home management (score range: 0-8), social leisure (score range: 0-8), private leisure (score range: 0-8) and personal or family relationships (score range: 0-8).
Time frame: Change from baseline to follow-up (Week 12)
Positive and Negative Affective Schedule (PANAS)
Change in reported positive affect and negative affect (score range for each scale: 10-50, higher scores indicate higher levels of positive affect or negative affect)
Time frame: Change from baseline to follow-up (Week 12)
Temporal Experience of Pleasure Scale (TEPS)
Change in reported anticipatory pleasure (score range: 10-60) and consummatory pleasure (score range: 8-48). Higher scores indicate higher reward responsiveness.
Time frame: Change from baseline to follow-up (Week 12)
Effort Reward Trade-off Task
Change in behavioral effort for reward (button presses for points) and experience of reward (happiness ratings). The Effort Reward Trade-off Task is a novel online behavioral task.
Time frame: Change from baseline to follow-up (Week 12)
Positive Valence Systems Scale (PVSS-21)
Change in reward anticipation, motivation, and consumption for rewards such as rewards such as food, physical touch, positive feedback, social interactions, hobbies and goals (score range: 21-105). Higher scores (e.g. 105) indicate higher reward responsiveness.
Time frame: Change from baseline to follow-up (Week 12)
