Core Tip

Core tip: In this study we examined the agreement between mini-mental state examination and montreal cognitive assessment in an older population attending mental health service outpatients. Although both scales assess the same construct (cognition) the agreement between them was modest. Further we delivered a conversion rule which can allow conversion of scores between these scales. The converted scores had a high agreement with original ratings. Finally, this new conversion rule was superior to three previously suggested equating rules.
