Abstract(s)
Objectives: To study the reliability/stability of the Cognitive Telephone Screening Instrument
(COGTEL) for the assessment of cognitive functions, and to investigate the concurrent
validity (that is, the relationship between the COGTEL scores and external variables,
such as level of education and MMSE results) in a pilot study of elderly persons residing
in the community in the municipal regions of Apuí, Fonte Boa and Manaus (Amazonas,
Brazil). Method: This pilot study included 90 elderly persons (29 men and 61 women) aged
60-85 years of age [68.2 (± 6.7)]. The COGTEL, the MMSE and socio-economic survey
were applied in the form of two interviews, a week apart and under the same conditions.
Results: The test-retest intraclass correlation coefficient of the COGTEL total score (and
respective six subtests), MMSE and educational level ranged from acceptable to high
(0.708 < R <0.946). There was a strong positive correlation between the total score of
the COGTEL with the MMSE (r =0.682; p <0.001), as well as with educational level (r
=0.604; p <0.001). Conclusion: This study presents preliminary evidence of the reliability/
stability and concurrent validity of the COGTEL in the evaluation of cognitive functions
in elderly persons residing in the community. The results of this study support the use of
COGTEL as a short, reliable and valid instrument for analyzing differences in cognitive
functioning in inter-individual studies with elderly persons.
