BECK’S NEGATIVE TRIAD
- Explains why some people are more vulnerable to depression than others.
3 parts to this cognitive vulnerability:
negative self-schemas – package of ideas that holds negative beliefs and views about
ourselves (develops in childhood due to negative experiences)
cognitive biases - we see and interpret things in a negative way (e.g., selective abstraction/
catastrophising, black and white thinking) develop in adulthood
negative triad – this negative cycle of thinking leads to negative views about the self, world
and future leading to depression
ELLIS’ ABC MODEL
- Good mental health is the result of rational thinking, mental health problems derive
from irrational thoughts.
A ACTIVATING EVENT – external event triggers irrational beliefs
B BELIEFS – irrational beliefs about ourselves and the world
C CONSEQUENCES – leads to negative emotions and behaviours.
“People are not disturbed by things but rather their view of things”.
