They were randomized into derivation (<italic>n</italic> = 303) and validation (<italic>n</italic> = 303) groups. The SMMSE score was built from six memory items of MMSE, with a score ranging from 0 to 6 (i.e. best performance).</p> </sec> <sec id="ene3830-sec-0003" sec-type="section"> <title>Results</title> <p>The receiver operating characteristic curve showed an area under the curve of 0.98 for the derivation group and 0.97 for the validation group without differences between curves (<italic>P</italic> = 0.254). The cut‐off between the sensitivity and the specificity of the SMMSE score for clinically diagnosed dementia was ≤4. The performance of the SMMSE for the diagnosis of dementia was high in the derivation and validation groups: sensitivity at 93.1% and 93.8%, specificity at 93.8% and 90.5%, positive predictive value at 94.3% and 90.1%, negative predictive value at 92.5% and 94.0%, likelihood ratio of positive test at 14.9 and 9.8 and of negative test at 0.07 and 0.07, respectively.</p> </sec> <sec id="ene3830-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The Short Form of the Mini‐Mental State Examination was a good screening test for dementia in older individuals followed in a memory clinic for a memory complaint.
