The Impact of Virtual Physical Activity Interventions on Depression and Anxiety among College Students: Randomized Controlled Trial (Preprint)
BACKGROUND Depression and anxiety are growing issues for college students, with both aerobic-resistance training and mindfulness-yoga exercises known to be effective in reducing symptoms and severity. However, no known research is available comparing these two depression and anxiety interventions simultaneously and in a virtual environment. OBJECTIVE This study aimed to determine the effects of a virtual aerobic-resistance exercise intervention (WeActive) and a virtual yoga-mindfulness mindfulness exercise intervention (WeMindful) on depression and anxiety symptoms in college students METHODS The participants were 78 college students who anonymously completed a Qualtrics survey including the Generalized Anxiety Disorder Scale (GAD-7) and the Major Depression Inventory (MDI) at baseline and the post-test. Participants were randomly assigned to either the WeActive or WeMindful group and underwent two 30-minute virtual aerobic-resistance exercise lessons or yoga-mindfulness lessons per week for eight weeks. RESULTS The results of ANCOVA with repeated measures indicated that, while not statistically significant, both groups showed a notable decrease in anxiety with a marginal significant main effect of time (F = 3.485, p = 0.066, η2 = 0.047) but no significant main effect of group and no significant interaction effect of time with group. The two intervention groups experienced a significant decrease in depression with the main effect of time (F = 3.892, p = 0.052, η2 = 0.052). There was no significant main effect of group or interaction effect of time with group for depression. CONCLUSIONS College students in both WeActive and WeMindful groups experienced a significant decrease in depression symptoms and a decrease, though not significant, in anxiety as well. The study suggests that virtual WeActive and WeMindful interventions are effective approaches to managing US college student depression and anxiety during a pandemic.
