Three Factors That Influence Resilience
1) Reliable comfort – having someone to confide in or lean on in times of trouble, and being able to get help from other people when needed
2) Social connectedness – whether their physical health or emotional problems interfered with social activities like visiting friends and relatives and interacting socially with neighbors or groups
3) Daily functioning – having difficulties with their normal activities because of emotional problems like depression or anxiety.
