Introducing two types of psychological resilience with partly unique genetic and environmental sources

Abstract Psychological resilience is indicated when individuals demonstrate good mental health despite exposure to significant stress or adversity. Good mental health may involve low levels of illbeing and/or high levels of wellbeing. There is still very limited knowledge about the potential differe...
