Abstract

Background: The objectives of this study were to examine the reliability and validity of a 26-point telephone version of the Cantonese Mini-mental State Examination (T-CMMSE) for a sample of 65 elderly patients, comprising 31 patients without dementia and 34 patients with dementia, in an acute regional hospital in Hong Kong, and to identify an optimal cut-off score to discriminate between those patients with dementia and those without.

Methods: Participants were rated by using the face-to-face Mini-mental State Examination (MMSE) before inpatient discharge and the T-CMMSE after inpatient discharge, and were rated separately by two raters in two telephone follow-up sessions using the T-CMMSE.

Results: The results of the study indicated that the scale had excellent inter-and intra-rater reliabilities. There was substantial agreement between the two versions of the examination (κ > 0.6–0.8 ≤) for orientation, registration, and recall items. An optimal cut-off score of ≤ 16 was suggested for the T-CMMSE to discriminate between those with and without dementia.

Conclusion: The T-CMMSE can be used in telephone follow-ups as an alternative to the conventional face-to-face version.
