Depression has a lifetime prevalence rate of 20.6% and has one of the highest prevalence rates of mental health disorders. Major depressive disorder can lead to higher costs of living for individuals as well as a larger economic decrease associated with inability to work. Current treatment targets one of the two core symptoms of depression of decreased mood or loss of interest in activities. However, current treatment models are not enough because there are more individuals who require treatment than treatment opportunities which creates inequities of care. Digital interventions provide a unique opportunity to increase widespread accessibility of treatment at reduced and scalable costs. Virtual reality is a newer type of digital intervention that consists of providing experiences for individuals that are different from the physical environment they are currently in. Through audio and visual displays, virtual reality creates a sense of presence, or the experience of immersion, with an environment. Virtual reality has been used in a variety of clinical psychology areas such as training, assessment, and treatment of mental health disorders and other medical conditions. Despite research finding efficacy for virtual reality with anxiety and PTSD, few studies have examined the impact of virtual reality on depressive disorders and low mood. Of studies that have looked at mood changes, most studies measured indirect measures of mood such as energy levels which leads to a gap of research on the efficacy of virtual reality with low mood. The present study aims to examine if virtual reality exergames improve participant's mood and affect. Additionally, the study will determine if there are different effects of presence, depressive symptoms, and technology familiarity on mood. Furthermore, the study will examine helpfulness and satisfaction to examine usability of virtual reality as a medium for clinical intervention.
Once participants consent, they will complete the three demographic questions and their familiarity with virtual reality. Participants will also complete the Patient Health Questionnaire-8(PHQ-8), Affinity for Technology Interaction scale (ATI), Positive and Negative Affect Schedule (PANAS), and the mood sliding scale. Participants will then be informed that they are going to watch a short clip and press play to watch a 2-minute video of Lion King. After the sad mood induction, participants will complete the PANAS and a mood slider scale. Participants will then be randomly assigned to the virtual reality or control condition. In the virtual reality condition, participants will be asked to complete the first course a virtual reality game called "The Climb". In the control condition, participants will be told that they will be watching a video of a virtual environment climbing game and then be asked to copy all hand movements as accurately as they can. After completing either the virtual reality or control condition, individuals will then complete the PANAS, mood scale, temple presence inventory, three feedback questions, net promoter question, and an open-ended question on improving the activity they just completed. Participants will then be debriefed about the study and compensated for their time.

Change in Positive Affect and Negative Affect From Baseline to After a 2 Minute Mood Induction
There are twenty total items of the Positive and Negative Affect Schedule. The Positive and Negative Affect Schedule has two subscales, negative affect and positive affect, that consist of 10 items each on a 5-point likert scale from 1 (very slightly or not at all) to 5 (extremely). The PANAS has different time instructions based on when the researcher would like to measure affect and the moment instruction was used. The minimum value for each subscale is 1 and the maximum for each subscale is 5. Each subscale is calculated from an average of 10 items that compose of the subscale. Higher scores indicate more endorsement of positive affect or negative affect depending on the subscale endorsed. Individuals were provided the Positive and Negative Affect Schedule at baseline and after completion 2 minute of mood induction.
Time frame: Baseline to after 2 minutes of mood induction
Change in Positive Affect and Negative Affect From Mood Induction to After Condition Completion
There are twenty total items of the Positive and Negative Affect Schedule. The Positive and Negative Affect Schedule has two subscales, negative affect and positive affect, that consist of 10 items each on a 5-point likert scale from 1 (very slightly or not at all) to 5 (extremely). The PANAS has different time instructions based on when the researcher would like to measure affect and the moment instruction was used. The minimum total value for both positive and negative affect subscales is 10 and the maximum total value for each subscale is 50. Higher scores indicate more endorsement of positive affect or negative affect depending on the subscale endorsed. Participants were measured after mood induction and after completion of the virtual reality or control condition. A change in score was calculated by subtracting the total value of the negative subscale before and after the time point and subtracting the total value of the positive subscale before and after the time point.
Time frame: Mood induction to after an average of 15 minutes of virtual reality or control condition
Temple Presence Inventory Score Total
The Temple Presence Inventory measures the amount of presence across different technologies such as virtual reality. The Temple Presence Inventory has eight subscales that measure the following dimensions: spatial presence, social presence with actor in medium, passive social presence, active social presence, presence as engagement, presence as social richness, presence as social realism, and presence as perceptual realism. Only spatial presence and presence as engagement was utilized in the study to determine presence as no social interaction was utilized in the study. Each item is rated on a 7-point scale from 1 (not at all) to 7 (very much) with higher mean subscale scores reflecting higher association with the specific presence factor. The minimum value for each subscale was 1 and the maximum value was 7. Each participant was only measured once approximately 30 minutes after the start of study after they completed rather the virtual reality condition or control condition.
Time frame: One measure after approximately 30 minutes after start of study
Patient Health Questionnaire Depression Scale Total
The Patient Health Questionnaire-8 is an 8-item self-report measure used to screen for major depressive episodes and the severity of depressive symptoms. Each item is rated on a 4-point scale from 0 (not at all) to 3 (nearly every day) with higher mean scores reflecting more depressive symptoms. Individuals were measured once at the beginning of the study. The minimum value for the PHQ-8 was 0 and maximum was 24.
Time frame: Approximately 5 minutes after start of the study
Affinity for Technology Interaction Scale Total Score
The Affinity for Technology Interaction Scale is a 9-item measure used to assess an individual's level of engagement with technology. Each item is rated on a 6-point Likert scale from 1 (completely disagree) to 6 (completely agree). Items 3, 6, and 8 are reverse coded and a mean score is calculated with higher scores reflecting an individual having more independence and utilization of technology. Each participant completed the measure once after completion of the virtual reality condition or control condition. The minimum score was 1 and maximum was 6.
Time frame: Once approximately 30 minutes after start of study
