Item-level information herewith provided for the Italian MoCA can help interpret its scores by Italian practitioners. Memory items showed high discriminative capability, along with certain items assessing executive functions and orientation. Several items proved to be scarcely sensitive, especially the place item from Orientation and the letter detection task. Substantial disagreements with previous ESs classifications were detected. No sex differences were detected when tested along with age and education. ResultsĪge and education significantly predicted all MoCA measures except for Orientation, which was related to age only. Agreement with previous ESs classification was assessed via Cohen’s k. Normative values were derived by means of the Equivalent Scores (ESs) method, applied to the MoCA and its sub-scales. Item Response Theory (IRT) was adopted to assess item difficulty and discrimination. Methodsįive hundred and seventy nine healthy individuals from Northern Italy (208 males, 371 females age: 63.4 ± 15, 21–96 education: 11.3 ± 4.6, 1–25) were administered the MoCA. This study thus aimed at providing: (i) updated, region-specific norms for the Italian MoCA, by also (ii) comparing them to pre-existing ones with higher geographical coverage (iii) information on sensitivity and discriminative capability at the item level. doi: 10.1590/0004-282X20190130.The availability of fine-grained, culture-specific psychometric outcomes can favor the interpretation of scores of the Montreal Cognitive Assessment (MoCA), the most frequently used instrument to screen for mild cognitive dysfunctions in both instrumental and non-instrumental domains. MoCA test: normative and diagnostic accuracy data for seniors with heterogeneous educational levels in Brazil. The montreal cognitive assessment: normative data from a large Swedish population-based cohort.
A subtest analysis of The Montreal Cognitive Assessment (MoCA): which subtests can best discriminate between healthy controls, mild cognitive impairment and Alzheimer’s disease? Int Psychogeriatr. Dementia incidence continues to increase with age in the oldest old: the 90+ study. 2017.Ĭorrada MM, Brookmeyer R, Paganini-Hill A, et al. Revision, custom data acquired via web-site. United Nations Department of Economic and Social Affairs Population Division. The equivalences of the three cognitive tests (MMSE, MoCA-30, MoCA-22) in the oldest-old will facilitate continuity of cognitive tracking of individuals tested with different tests over time and comparison of the studies that use different cognitive tests.ĩ0 + MMSE MoCA-22 MoCA-30 Oldest-old Score conversion. Subtest, domain and MoCA-22 norms will aid in evaluation of the oldest-old who cannot complete the MoCA-30 or are tested over the phone.
An MMSE score of 27 is equivalent to a MoCA-30 score of 22 and a MoCA-22 score of 16. MoCA-22 total score norms are: mean = 18.3(standard deviation = 2.2).
Second, we derived score equivalences for MMSE to MoCA-30 and MoCA-22, and MoCA-30 to MoCA-22 using equipercentile equating method with log-linear smoothing, based on all 157 participants. These norms were derived from 124 participants with a Mini-Mental State Examination (MMSE) ≥ 27. First, we derived norms for (1) subtests and cognitive domains of the in-person Montreal Cognitive Assessment having a maximum score of 30 (MoCA-30) and (2) the total MoCA-22 score, obtained from the in-person MoCA-30 by summing the subtests that do not require visual input to a maximum score of 22. To provide norms and score equivalence for commonly used cognitive screening tests for the oldest-old.ĭata on 157 participants of the Center for Healthy Aging Longevity Study aged 90 + were analyzed. However, norms and score equivalence for screening tests are lacking for this group. This age group is the fastest growing and has the highest risk of dementia. Cognitive screening is important for the oldest-old (age 90 +).
