Overview of Mixed Methods Study Design.
Note. The pre- and post-intervention surveys were sent to students in both the intervention and comparison groups, while the collection of messages and interviews occurred with the intervention group only. Qualitative and quantitative data were analyzed independently and then compared to explore the study’s research questions.
