ranged from 3.3 and above to 3.6 and above, while in patient samples the cutoff scores have ranged from 3.4 and above to 4.0 and above. To improve the detection of dementia, the IQCODE can be used in combination with the Mini-Mental State Examination. A graphical method of combining the two tests has been developed and is known as the Demegraph. Validity of the IQCODE The IQCODE has been found to distinguish people who have or do not have dementia. A low score on the IQCODE in a person who does not currently have dementia has also been found to predict that they will develop dementia in the future. The IQCODE has found to correlate highly with conventional dementia screening tests, such as the Mini-Mental State Examination, and to have moderate correlations with a range of neuropsychological tests. It has also been found to correlate with change in cognitive test scores over time. The IQCODE has near-zero correlations with a person's level of education or with their intelligence earlier in life. This is in contrast to conventional dementia screening tests like the Mini-Mental State Examination, which are affected by education and intelligence as well as the presence of dementia. Other versions of the IQCODE The original IQCODE has 26 items. A Short IQCODE has been developed, consisting of the 16 items, and has been found to be as valid as the full version. Because it is briefer and of equal validity, the Short IQCODE can generally be used in preference to the original version. Because the IQCODE does not require the involvement of the person being assessed, it can be used to assess probable dementia in someone who is unable to be assessed because they have had a stroke, developed delirium or have died. A Retrospective IQCODE has been developed for this purpose. The IQCODE has been translated into many languages, including Chinese, Danish, Dutch, Finnish, French, Canadian French, German, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Spanish and Thai.
