Major depression (MD) is the leading cause of disability in youth, with a global economic burden of >$210 billion annually. However, up to 70% of youth with MD do not receive services. Even among those who do access treatment, 30-65% fail to respond, demonstrating a significant need for more potent, accessible interventions for adolescent depressive symptoms and disorders.
The goal of this project is to assess the acceptability and effectiveness of a novel, single-session, virtual reality-based depression intervention—the VR Personality Project—teaching growth mindset: the belief that personal behaviors and characteristics, such as depressive symptoms, are malleable rather than fixed. In a previous trial, a single-session growth mindset intervention significantly reduced depressive symptoms in high symptom-adolescents; however, this intervention did not benefit all adolescents uniformly. For instance, the intervention reduced depression in adolescents who reported post-intervention increases in perceived control, but it did not lead to significant depression reductions in adolescents who reported small or no increases in perceived control. Thus, the VR Personality Project was designed to systematically target and increase adolescents' perceived control by offering a more immersive, active, and user-directed intervention experience than the web-based SSI can provide. By targeting an identified predictor of intervention response, the VR Personality Project may be lead to larger reductions in depression than the existing web-based mindset SSI.
To test this possibility, adolescents with elevated depressive symptoms or at high risk for depressive symptoms (N=159; ages 12-16) will be randomized to one of three intervention conditions: the VR Personality Project; the web-based growth mindset SSI tested previously; or an active control SSI, also tested previously. Adolescents and their parents will report on their depression symptoms, perceived control, and related domains of functioning at pre-intervention, post-intervention, and at three- and nine-month follow-ups. We predict that the VR and web-based SSIs will both lead to larger reductions in adolescent symptoms relative to the control SSI. Additionally, we predict that the VR-based SSI will lead to larger reductions in depression than the online SSI, and that these symptom reductions will be mediated by increases in adolescents' perceived control. Results may identify a particularly potent, mechanism-targeted, brief intervention for adolescent depression.
Psychiatric disorders are the leading cause of disability worldwide, and 40.5% of this burden is attributable to major depression (MD). Rates of MD increase markedly in adolescence, with nearly 20% of youth experiencing MD between ages 12 and 18. Adolescent-onset MD accounts for 66% of lifetime MD cases and predicts interpersonal problems, substance abuse, and a 20-fold increased risk for attempting suicide. Despite this early onset and protracted course, up to 70% of US adolescents with MD do not receive services. Even among those who do access treatment, 30-65% fail to respond. These findings highlight the urgent need for more potent and accessible MD interventions for adolescents.
Emerging work suggests that single-session interventions (SSIs) may increase accessibility of youth MD interventions. SSIs include core elements of comprehensive, evidence based treatments, but their brevity makes them easier to disseminate to diverse settings. Indeed, SSIs can successfully treat youth psychiatric problems: In a meta-analysis of 50 RCTs, it has been found that SSIs reduced youth mental health difficulties of multiple types (mean g=0.32), including self-administered SSIs (e.g., web-based SSIs; mean g=0.32). One SSI, in particular, has been shown to reduce adolescent MD symptoms: the growth mindset (GM) SSI, a web-based program teaching the belief that personal traits are malleable, which has prevented and reduced adolescent MD in recent RCTs. For example, in a recent RCT conducted by the principal investigator on the proposed study, the GM SSI led to post-intervention increases in adolescents' perceived control over behavior (d=.34, p<.001) and emotions (d=.19, p=.03) relative to a comparison (supportive therapy, or ST) SSI. The GM SSI also predicted steeper 9-month declines in youth depression symptoms per parent (B=-.99, p=.047) and adolescent reports (B=-1.37, p=.03), based on mixed-effects linear models.
However, it is notable that the GM SSI does not reduce depression in all adolescents. For instance, the intervention reduced depression in adolescents who reported post-intervention increases in perceived control over behaviors and emotions, but it did not lead to significant depression reductions in adolescents who reported small or no increases in perceived control. Thus, the potency of GM SSIs for adolescent depression has yet to be optimized. Such potency may be advanced by developing new iterations of the growth mindset intervention, which are designed to more systematically target predictors and mediators of clinical outcomes, such as perceived control. Such efforts may increase the promise of growth mindset interventions to produce greater symptom reductions for a larger proportion of youth experiencing distress.
Accordingly, the goal of the present study is to test the acceptability and effectiveness of a novel, single-session virtual reality-based growth mindset intervention—the VR Personality Project—for depressive symptoms in adolescents. The VR Personality Project was designed to systematically target and increase adolescents' sense of agency and perceived control by offering a more immersive, active, and user-directed intervention experience than the previously-tested web-based SSI can provide. By targeting an identified predictor and mechanism of intervention response, the VR Personality Project may produce larger reductions in depression than the existing web-based mindset SSI. Thus, this intervention may represent a mechanism-targeted, efficient strategy for reducing for adolescent depression--one that is both relatively affordable (less than $100 for any commercially-available VR headset, a fraction of the cost of long-term psychotherapy) and engaging to adolescents experiencing mood-related distress.
There are four specific study aims for this research:
AIM 1: Replication of past research. Our first aim is to replicate past research suggesting that single-session growth mindset interventions can significantly reduce depressive symptoms in at-risk adolescents. We hypothesize that adolescents who participate in a growth mindset intervention (web-based OR virtual reality-based) will show larger reductions in depression symptoms from baseline (pre-intervention) through the 9-month follow-up assessment, compared to adolescents who receive an active, web-based control program.
AIM 2: Evaluation of new virtual reality intervention, including a comparative efficacy study. Our second aim is to evaluate whether the new virtual reality-based growth mindset intervention (the VR Personality Project) can reduce depressive symptoms in adolescents, both relative to an active control program and relative to the previously tested web-based growth mindset intervention. We hypothesize that adolescents who participate in the virtual reality-based growth mindset intervention will show larger reductions in depressive symptoms from baseline (pre-intervention) through the 9-month follow-up assessment, compared to adolescents who receive the web-based growth mindset intervention AND adolescents who receive the active web-based control program.
AIM 3: Testing mediation through perceived control. The VR Personality Project was explicitly designed to target and increase adolescents' perceived control by offering a more immersive, active, and user-directed intervention experience than the the web-based growth mindset SSI can provide. Thus, the third goal of this study is to examine whether the VR Personality Project does, in fact, reduce adolescent depressive symptoms by eliciting proximal increases in perceived control. We hypothesize that the VR Personality Project will lead to larger increases in perceived control than either web-based intervention from pre- to post-intervention, and that these increases will mediate subsequent reductions in adolescent depression across the follow-up period.
AIM 4: Gauge the relative acceptability and feasibility of the VR intervention. Adolescents' perceptions of any intervention can impact completion rates, program engagement, and ultimately intervention effectiveness. Thus, an additional aim of this research is to examine whether adolescents view the VR Personality Project as more engaging, helpful, and interesting than the web-based growth mindset intervention or the web-based control intervention.

Participants will be partly blind to condition =. A computer-based survey will randomize participants into one of three conditions: an online mindset program, an online control program, or a virtual reality program. If a participant is randomized into one of the first 2 programs, the participant will know that s/he is not assigned to the VR program, but neither the experimenter nor the participant will be aware of which of the two computer-based programs s/he is completing. However, both participants and the experimenter leading the study visit will be aware of whether he participant was allocated to the VR condition (specific equipment set-up is required). The experimenters leading the study visits will be trained RAs not involved in data analysis. The study PI will remain blind to participants' condition assignments.Primary Purpose: Treatment
