Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Interventional Model Description: Single case design (multiple baselines)
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Virtual reality treatment<br>Use of google maps with virtual reality to virtually situate the participants into scenarios that are motivating for them (i.e., the beach, a mountain, a park, etc.) at their choice. | Other: Behavioral activation using virtual reality<br>* The investigators will encourage behavioral activation (increase in the number and time of conducted activities) situating the person in motivating situations using virtual reality<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Behavioral activation | In a scale from 0 (not at all) to 6 (completely), to what extent were you satisfied with what you did today? | Change through study completion, an average of 31 days. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline vs posttreatment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Mood | In a scale from 0 (completely sad) to 100 (completely happy), how did you feel today? | Change through study completion, an average of 31 days. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | 
| Change in Depression | In a scale from 0 (not at all) to 3 (completely), how was your level of depression today? | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | 
| Change in Positive affect | In a scale from 1 (not at all) to 5 (completely), how was your positive affect today? | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | 
| Change in Negative affect | In a scale from 1 (not at all) to 5 (completely), how was your negative affect today? | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) | 
| Change in Activity level | In a scale from 0 (minimum) to 100 (maximum), what was your activity level today? | Change through study completion, an average of 31 days.. The outcome will be evaluated daily (at 9pm) during 31 days. Changes will be investigated from baseline to posttreatment using all corresponding time points (baseline to posttreatment) |
