Problem Statement: Nursing students experience high stress levels that can negatively impact academic performance, clinical decision-making, long-term mental health, and lead to attrition from nursing programs. However, most programs do not teach coping strategies to student nurses to reduce attrition, improve coping, and prevent health consequences for the student nurse population. Purpose: The project aimed to determine whether providing a mobile application for stress management would promote student self-efficacy.Methods: MindShift® CBT mobile application was introduced to project participants to provide interactive cognitive-behavioral and mindfulness tools to manage stress. A mixed methods pre-test/post-test design was used to evaluate perceived stress and self-efficacy before, at the midpoint, and after the intervention using the Perceived Stress Scale and General Self-Efficacy Scale. Inclusion Criteria: Students enrolled in nursing programs at a community college in the Midwest United States. Analysis: Results of the Friedman rank sum test were significant based on an alpha value of 0.05, X[superscript 2] (2) = 7.24, p = 0.027, indicating significant differences in the median values of pretest, midpoint, and posttest General Self-Efficacy Scale after intervention. Implications for Practice: Provision of a mobile stress management application can improve nursing students' self-efficacy. A downward trend in perceived stress and upward trend in self-efficacy indicate clinical relevance for providing this tool, particularly for first semester students.
