Why is Hiller et al (1992) supporting evidence of the ICD classification system?
Hiller gave case notes of 100 psychiatric patients with symptoms of Sz to 4 different clinicians and asked for a diagnosis
Found an 80% rate of agreement using the ICD-10 when diagnosis for Sz showing reliability for this manual
Why is Pihlajamaa et al (2008) supporting evidence of the ICD classification system?
Pihlajamaa found that when ICD-10 is used to diagnose Sz the diagnosis matches a diagnosis using a different classification system
Suggests it is a valid diagnostic tool
Why is accessible a strength of the ICD classification system?
ICD-10 is used significantly more than DSM-5 by psychiatrists around the world
(70% compared to 23% in a study by Reed et al 2011)
Suggesting it is more user-friendly and accessible- likely due to the fact it is a free resource and multi-lingual
Why is being produced by WHO a strength of the ICD classification system?
ICD-10 is produced by a global health agency (WHO) and provides very specific detail for diagnosis of disorders which enables practitioners to do more research into the causes of mental illness and ultimately advances medical technology in helping develop cures
Why is sophisticated structure a strength of the ICD classification system?
ICD-11 has a more sophisticated structure than the ICD-10
With around 55,000 codes that can be used to classify diseases, disorders, injuries and causes of death
ICD-11 offers a fine level of detail in coding these illnesses
Why is Cheniaux et al (2009) refuting evidence of the ICD classification system?
Cheniaux found that Sz was diagnosed more frequently when using ICD-10 than when using DSM-IV
Suggests a lack of reliability between the two systems
This difference may be due to the duration of symptoms - six months for DSM and one month for ICD
Why is Jansson et al (2002) refuting evidence of the ICD classification system?
Jansson studied the concurrent validity of ICD-9 and ICD-10
155 patients in Copenhagen were assessed between 1998 and 2000
ICD-10 was found to be less valid than ICD-9 when diagnosing Sz
