Study summary

To understand the potential effectiveness of a 4 week Mindfulness-Based Cognitive Therapy intervention delivered using a smartphone application for reducing anxiety and stress within college students.

Read the detailed description

The objective of this project is to understand the potential effectiveness of a 4 week Mindfulness-Based Cognitive Therapy intervention delivered using a smartphone application for reducing anxiety and stress within college students. Although in-person mindfulness-based cognitive therapy approaches have been found effective for reducing anxiety and stress; given the pervasiveness of anxiety and stress in this population, there is a need to provide alternative and accessible interventions to improve students' mental health. One such approach may be by leveraging existing tools such Sanvello - a free mindfulness-based cognitive therapy smartphone application - which could more easily be deployed across a broader population. Accordingly, using a cluster-randomized controlled design, this intervention will assess the extent to which 4-weeks of using the Sanvello application was effective for reducing anxiety and stress within college students.

    Positive Control

    The control experimental group received training on the utilization of mindfulness-based stress reduction breathing techniques. Participants were instructed to set a timer for 5 minutes in order to engage in mindfulness breathing. Comprehensive instructions were provided during the initial laboratory time, elucidating the method by which participants were to direct their attention towards their breath. Moreover, participants were encouraged to cultivate a non-judgmental attitude when confronted with potential distractions and to subsequently redirect their focus back to their breathing. Participants were advised to integrate this technique into their daily lives as a means to alleviate anxiety and stress.

    Behavioral: Mindfulness Practice

  • Experimental
    Mindfulness-Based Cognitive Therapy intervention

    The active experimental group received a mindfulness based cognitive therapy through the Sanvello smartphone application. Participants were encouraged to practice mindfulness daily through the application program "Braving Anxiety," which consisted of 35 modules. The anxiety management program consists of 1) Watch, 2) Read, 3) Listen, 4) Plan, 5) Listen - Mindfulness practice.

What researchers measure

Primary outcomes

  1. State-Trait Anxiety Inventory

    Trait scale of the Spielberger State-Trait Inventory as an index of trait anxiety. The possible trait scores range from 20 to 80, with higher scores indicating greater levels of anxiety.

    Time frame: Change from baseline, 4 weeks.

  2. Perceived Stress Scale

    The Perceived Stress Scale-4 as an index of perceived chronic stress levels. The possible scores range from 0 to 16, with higher scores indicating higher perceived chronic stress levels.

    Time frame: Change from baseline, 4 weeks.

Limitations and caveats
Although the intervention was not a priori designed as a crisis interventional approach, it was implemented only a month after a mass-shooting event occurred on campus. Thus as Foa et al. (2005, doi: 10.1037/0022-006X.73.5.953), observed that cognitive restructuring had limited effects on individuals with post-traumatic stress disorder (PTSD) and their perceived levels of chronic stress; it is important to acknowledge and consider the limitations this might introduce.

Participant flow

Potential participants were enrolled in a single predominately first year-level college course in health-sciences at Michigan State University.
