EVALUATION: RELIABILITY OF ICD-10 IN
DIAGNOSING SCHIZOPHRENIA
Strengths
Study to Support
Weaknesses
Evidence shows that
ICD-10 is a reliable
measure of
Schizophrenia. It also
in comparison to DSM
III has research to
suggest that it is more
reliable.
Schizophrenia was
diagnosed more
frequently when ICD10 was used than
when DSM IV was
used suggesting that
there is a lack of
reliability between the
two systems.
Studies use inter-rater
reliability
Schizoaffective
disorders were not
reliably diagnosed.

EVALUATION: VALIDITY OF ICD-10
IN DIAGNOSING SCHIZOPHRENIA
Strengths
Study to Support
Weaknesses
When ICD-10 is used
to diagnose
schizophrenia the
diagnosis matches a
diagnosis using a
different system.
Different versions of
the ICD classification
systems focussed on
different symptoms
and features.
Research
demonstrated that
ICD-10 and DSM IV
gave in excess 80%
agreement in
diagnosis.
Studies on validity are
difficult to carry out
given the complexity
of the disorder.
