Students can experience multiple stressors during their academic life which have an impact on their emotional health and academic progress.This study sought to explore students' understanding of and factors affecting their emotional well-being in an undergraduate nursing programme at a private nursing institution in Karachi, Pakistan.In this qualitative study, data were collected through individual semi-structured interviews using a self-designed guide from 16 participants in total, drawn from various years of the selected undergraduate programme.Participants noted that the quality of the 'learning environment' was a key influence on their emotional well-being. They highlighted faculty role and teaching approaches, academic expectations and availability of learning resources as important factors that affected their emotional well-being as well as their academic performance. Institutional support was also deemed important. Factors associated with a 'hidden curriculum' were found to be a threat to students' emerging sense of professionalism.Suggestions are given as to how the learning environment in the nursing programme under study can be improved to take into account students' emotional well-being. Emphasis needs to be laid on developing supportive faculty role to provide conducive learning environment and professional development of students. Efforts to develop stress-free academic environment with supportive institutional policies need to be considered.
