Key skills






Re-frame symptoms as
depression
Link to life events
Negotiate antidepressants if necessary
Problem list and
priorities
Set realistic time scale
Agree regular review
Explanations


Depressive illness
is clinically different
from the blues and
involves chemical
changes in the
brain.
Depressive illness
has characteristic
symptoms and
explain them.
Explanations

Depression benefits
from both drug and
non-drug
approaches.


“Pills for symptoms.”
“Talking for
problems.”
Explanations


Anti-depressants
are not addictive or
habit forming.
Anti-depressants
take 2-3 weeks to
begin to work and
need to be taken for
4-6 months after the
full benefit is
obtained to prevent
relapse.
Explanations



Side effects occur
and are expected –
explain.
Drugs enable talking
therapy to work
better.
Regular review is
important and needs
to continue for at
least 6 months.
Explanations


Talking therapy can help solve
problems that are soluble, cope with
the insoluble and examine other
problems that seem unrealistic to the
patient or therapist.
Prevention of further trouble will be
considered when the treatment is
coming to an end.
