This study compared first generation and non-first generation doctoral students' levels of perceived stress, sense of coherence, and mindfulness. These variables were assessed both separately for each trainee group and in hypothesized relationships with each other. In addition, moderator analyses were conducted to assess whether key relationships between these variables differed in strength across the two trainee groups. Results from this study indicated that there were no significant differences among the two groups with regards to levels of perceived stress or sense of coherence levels. All trainees, regardless of generational status, reported a significant negative relationship between perceived stress and sense of coherence levels and between perceived stress and mindfulness levels. The relationships between perceived stress and sense of coherence were moderated by generational status, while the relationship between perceived stress and mindfulness was not significantly moderated by generational status. Implications of these findings and directions for future research are further discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC.
