A reduced version of the Face-Hand Test (FHT), the FHT-R, was applied to a random sample of 91 elderly subjects living in the community (S. Paulo-Brazil), to study the instrument's ability to detect Organic Brain Syndrome (OBS). The scores of the FHT-R test were then compared with a psychiatric assessment using the Clinical Interview Schedule. Five persons were regarded as OBS "cases" and 86 as OBS "non cases". At the cut-off point 0/1 the validity coefficients were as follows: Sensitivity 60%, Specificity 94%, Positive Predictive Value 38%, Negative Predictive Value 98% and Overall Misclassification Rate 8%. The usefulness of this clinical test to screen for OBS in epidemiological surveys is discussed.
