Urie Bronfenbrenner Ecological Systems Theory

EST

A: A psychosocial developmental theory that explains behaviour as shaped by multiple environmental systems. Development is influenced by interconnected contexts, not a single factor.

• Behaviour = result of interaction between systems

• Every factor is linked in an ecological chain

• Focus: person + environment together

Development is shaped by the interaction and interdependence of multiple environmental levels.

• Systems influence each other

• Development is dynamic and contextual

• Useful for understanding risk, protection, and resilience

Risk Concepts

• Risk: possibility of harm

• Vulnerability: susceptibility to negative outcomes

• Risk factors: biological, psychological, social, economic influences that increase harm

• Risk behaviours: behaviours increasing likelihood of harm

• Protective factors: reduce likelihood of harm or buffer risk

• Resilience: ability to adapt successfully despite risk exposure
