PEDRAZA, Olga Lucía et al. Intra and interrater reliability of the Minimental State Exmination (MMSE) and Montréal Cognitive Assessment (MoCA test) applied by health personnel in training. Acta Neurol Colomb. [online]. 2016, vol.32, n.1, pp.35-40. ISSN 0120-8748.

Introduction: The instruments for screening cognitive functions, applied to subjects in clinical settings and research, are useful for determining if this person has any trouble in cognition or show changes in the time. The usefulness of these instruments is defined with the evaluation of their psychometrics properties. Objective: This study allows to determine the intra and inter-observer agreement, when the MoCA test and MMSE were applied by a group in training process Materials and methods: The study group who attended two training sessions, with an interval of 5 months, scored the MoCA test and MMSE, from two patients which were filmed responding the tests, previous informed consent signature. We compared how close were the scores of participants among themselves by concordance correlation coefficient of Lin (rho) and with those given from the others by intra-class correlation coefficients (ICC). Results: In total, 46 participants were included. Intra-rater reliability was high for MoCA test (ICC = 0.86), but it was poor for MMSE (ICC=0.24). Inter-rater was poor for MoCA test (rho patient 1= 0.012, rho patient 2= 0.152) and MMSE (rho patient 1 = 0.008, rho patient 2 = 0.012). Although the scores between participants and gold standard were different, the diagnoses were similar. Conclusion:The correct scoring of the test, requires several trainings to clinical and research groups, and although they can be found few differences between scores applied by non-expert personnel, if the scores mistakenly given, are close to the cut-of point proposed for each test, the bias increases.
