The purpose of this qualitative single case study was to explore pre-licensure Bachelor of Science in Nursing (BSN) students' knowledge of mindfulness meditation (MM) using a smartphone app (SMA) to manage stress and promote resilience. Guiding this study was the transactional model of stress, adaptation, and coping by Lazarus and Folkman (1984) and the zone of proximal development (ZPD) educational theory by Vygotsky. The study asked the following questions: What was pre-licensure Bachelor of Science of Nursing (BSN) students' knowledge of mindfulness meditation (MM) using a smartphone app (SMA) to manage stress and promote resilience? What had the prelicensure BSN student experienced regarding MM with an SMA? What did prelicensure BSN students know about MM using an SMA to manage stress? What did prelicensure BSN students know about MM using an SMA to promote resilience? A sample of 91 students was obtained to answer the demographic questionnaire and three surveys. From those students, 25 volunteered for interviews and focus groups with 14 BSN students for interviews and 11 students split into two focus groups. The data were collected from surveys, interviews, and focus groups, and themes were developed. Data obtained contributes to current knowledge, and recommendations for further research are given.
