In the 1960s, Garmezy’s research began to focus on competence in children at risk for psychopathology. Then in the 1970s his research laid the groundwork for the international longitudinal study of resilience, science and developmental psychopathology. This was known as the project competence longitudinal study and continued for more than 20 years. The goal was to learn about resilience and to determine protective processes, measure key aspects of competence and exposure to risks that could explain how children overcome adversity. This study also identified the influence both internal and external factors have on the development of resilience. The groups were those who showed average or above average socioeconomic resources, cognitive skills, openness to experience, drive for mastery, conscientiousness, close relationship with parents, adult support outside the family and feelings of self-worth.
