Conclusions
The majority of screening tests to detect cognitive
impairment are strongly influenced by educational
level, and most of them are not useful for illiterate
subjects.
The MT was administered to 309 subjects older than
60 years-old without cognitive impairment
or
dementia, recruited from the general neurology
clinics. For each subject different parameters were
controlled: age, gender, handling of coins (never,
occasionally, frequent), years of education (none,
less than 10, more than 10), educational level
(illiterate, can read and write but not fluently, can
read and write fluently) and the neurological problem
to attend the clinic (potential capability to induce or
not cognitive impairment). Multiple linear regression
was performed to examine the relationship between
the total score of the MT and qualitative variables of
interest. A factorial analysis of the MT was
performed by the principal component method with
Varimax rotation.
305 subjects (98.7%) concluded the MT in 4.7+ 1.7
minutes (fig. 2) with scores of 24±3 (fig 3) with a
median =25 and score of 20 and 18 for percentiles
10 and 5, respectively. The distribution of subjects
according to years of education, educational level
and handling of coins is presented in graphics. The
total score was not influenced by gender, years of
education or neurological problem, but was
influenced by age (>70 y.o. β= -1.37 p<0.001),
handling of coins (never= ref.; occasionally: β= 2.15
p<0.001; frequent: β= 3.68 p<0.001), and
educational level (illiterate =ref.; no fluent read and
write: β= 2.38 p<0.001; fluent: β= 3.32 p<0.001).
(Table 1). The 4 factors with autovalue >0.9
attained the 64% of the variance of the MT score
and were independently correlated with the memory
and fluency items (the first), calculations (second)
and recognition (third), the last factor had a
negative correlation with intrusions number in
fluency tasks (Table 2).
The MT is easy to perform, fast, ecological and
well accepted by the subjects. It was
concluded for most subjects, including illiterate
subjects. The total score is not influenced by
years of education but it is influenced by
educational level. The factorial design
suggests that the MT explores different
cognitive domains, specially memory and
calculation, in an independent way. Moreover,
it can evaluate indirectly the functional
capability of the subject and his/her social
adaptation. It is useful to be applied to any
culture or country.
These circunstances imply that the utility of these
screening tests is very low in populations with a high
prevalence of low educational level subjects, in which
there will be more convenient to apply tools not
influenced by education and feasible to perform by
illiterate subjects.
Objective
Design and evaluation of a screening test to detect
cognitive impairment in low educational level
populations, to be applied to illiterate subjects.

The Money Test (MT) is based on the knowledge
and practical use of 12 local coins, exploring items of
recognition, recall, handling, calculation and memory
of the used coins. (Figure 1; AppendixI)

The Money Test
I am going to explore your memory, please listen carefully to everything that follows.
Do you remember how many different legal coins are there in Spain at this moment? Pay
you special attention to the fact that the question is about coins and not about bills.
