• Conditions: Depression - Major Depressive Disorder; Anxiety; Stress

• Registration Number: NCT07130734
• Lead Sponsor: Auburn University

Brief Summary

The present study will assess the effects of a four-week digitally delivered intervention on physical activity and depressive symptoms among adults experiencing at least moderate depressive symptoms. The main questions this research aims to answer are:

* Does a digital intervention reduce symptoms of depression?

* Does a digital intervention increase physical activity levels?

Researchers will compare a digital intervention promoting physical activity to a passive control (does not receive the intervention) group to see if the digital intervention works to reduce depressive symptoms and increase physical activity levels.

Participants will:

* Visit the laboratory at two separate time points before group assignment, separated by one week of physical activity monitoring

* Be randomly assigned to complete four weeks of a digital intervention prompting engagement in physical activity or have their mental health symptoms monitored over four weeks (i.e., passive control group)

* Visit the laboratory at two separate time points after the intervention, separated by one week of physical activity monitoring

Detailed Description

Procedures include four laboratory visits: two visits before the intervention and two visits after the intervention.

Participants will be randomly assigned to either four weeks of a digital intervention that prompts participants to engage in physical activity or a waitlist (passive) control condition. Participants will be randomized using a stratified approach using depressive symptoms and physical activity measured at pre-intervention as strata.

The digital intervention group will be instructed to download a Pathverse mobile application on their Apple or Android smartphone device. The Pathverse mobile application will be used to send participants daily notifications to engage in physical activity of their choice. During the second pre-intervention visit, each participant will select approximately five types of physical activity they find enjoyable that they would like to engage in over the four-week intervention. Participants will report on the physical activity they completed, along with the duration and intensity of each activity. Participants will have the choice of time of day as to when they would like to receive daily notifications on their device.

Members of the passive control group will be informed that their mental health will be monitored over four weeks as a control condition. After the study, they will be offered the digital PA intervention, if desired.

Primary Outcome Measures

Name	Time	Method
Depressive Symptoms	pre-intervention, at the two-week time point during the intervention, and immediately after the intervention	Depression, Anxiety, and Stress Scale (DASS-21) will be used to assess changes in symptoms of depression. The DASS-21 includes 7 items that assess for depression. Total scores for depression range from 0-42, with higher scores indicating greater depression severity.
Moderate-to-vigorous physical activity	pre-intervention and immediately after the intervention	Physical activity will be assessed using a wrist-worn accelerometer before and after the intervention. Physical activity outcomes will be calculated as amount of time spent in a specific intensity.
