(2) Clinical registered nurses that obtained support from their families were more inclined to be placed in the Low stress-high self-demand group. (3) Social connection significantly mediated the relationship between nurses’ work engagement and perceived stress. (4) Work engagement demonstrated a non-linear relationship with both perceived stress and social connection. …”
