The Efficacy of a Mindfulness-Based Intervention for College Students Under Extremely Stressful Conditions

Abstract

Objectives: This study evaluates the effectiveness of a mindfulness-based intervention (MBI), called Koru mindfulness, among college students.

Methods: Undergraduate students (N = 34) participated in a 4-week mindfulness curriculum embedded within a college course, while a control group (N = 35) taking a different course did not. Notably, the intervention coincided with the start of a state-wide lockdown due to the COVID-19 pandemic.

Results: Despite the additional external stress, there was a significant main effect and a significant interaction between the intervention and time for state mindfulness, (the treatment group experienced increased state mindfulness). There was a significant main effect (higher for the control group) on coronavirus worry and a significant interaction between the intervention and time for perceived stress, with the treatment/control group experiencing decreased/increased stress over time. There was also a significant interaction between the intervention and time for sleep problems with the intervention group experiencing declines in sleep problems over time and also being more likely to experience optimal amounts of sleep over time.

Conclusions: The Koru intervention effectively increased state mindfulness, decreased stress, and improved sleep, suggesting that it is robust even under extremely stressful conditions. This study adds to the growing evidence that MBIs can play an important role in addressing rising concerns regarding the mental health of college students.
