Social group membership, burnout, and subjective well-being in new nurses in the life transition period: A cross-sectional study.

Multiple group membership was positively associated with life satisfaction and positive affect and negatively with burnout. Burnout influenced new nurses' negative effect in their life transition period. To improve new nurses' subjective well-being, it is essential to focus on their social group membership, encourage participation in group activities, and improve access to sociopsychological resources that can help them take their first steps as professional staff and develop as healthy members of society, which will foster sustainable healthcare systems.
