A Randomized Controlled Trial of Mindfulness Versus Yoga

Depression and anxiety disorders are two of the most common mental disorders in the United States. These disorders are prevalent among college students.The main objective of this study is to compare the effectiveness of two different types of intervention practices (mindfulness vs. yoga) and a noninterventional control group in mitigating the effects of depression and/or anxiety in college students.A sample of 90 students (both genders) over age 18 who had a diagnosis of anxiety and/or depression was recruited from 11,500 undergraduate college students in a mid-size university. The study's design included stratified-randomized controlled repeated measures with three groups: a mindfulness intervention group, a yoga-only intervention group, and a noninterventional group. Participants were randomly assigned to the aforementioned three groups. Participants in the intervention groups received an 8-week training either in mindfulness or yoga. Depressive, anxiety, stress symptoms, self-compassion, and mindfulness were measured at baseline, Week 4, Week 8, and Week 12.Depressive, anxiety, and stress symptoms decreased significantly (p < .01) from baseline to follow-up conditions in both the mindfulness and yoga intervention groups. The changes in mindfulness scores were also significant in both groups. However, the changes in self-compassion scores were significant only in the mindfulness intervention group. No significant changes in the control group were demonstrated.The findings from this study can provide useful information to nurses and other health care providers. This study may have implications for a cost-effective treatment for depression and anxiety.
