A PMHNP leads a weekly outpatient group therapy session for adults recovering from major depressive disorder. The group includes members at various stages of recovery. During a session, a member who has been in the group for eight months and has shown significant improvement shares her recovery journey with a newer member who expressed hopelessness about ever feeling better. The newer member later tells the group, 'Hearing her story gives me hope that I can get through this too.' The longer-standing member then states, 'Being able to help someone else makes me feel like my suffering wasn't for nothing.' Which combination of Yalom's therapeutic factors is most evident in this exchange?
