Psychometric Properties of Montreal Cognitive Assessment v8.2 Test: Pilot Study

Description

The world is rapidly ageing and, with increasing age, there is also a potential increase in patients with Alzheimer’s disease and dementia. This calls for a reliable screening tool that could easily and rapidly identify the symptoms of pathological cognitive decline. As currently such tools are not available in Latvia, the objective of this study was to examine the psychometric properties of the newly translated Montreal Cognitive Assessment test.. 65 Latvian native speakers aged 55 – 90 (M = 49.93, SD = 19.22) participated in the study and were divided into three groups – with diagnosis of dementia (n = 21), mild cognitive impairment (n = 18) and control group (n = 26). All participants were assessed using the Montreal Cognitive Assessment test (Nasreddine et al., 2005), and a test-retest was conducted after 2 weeks (n = 37). . Almost all reaction indices and inter-item correlation coefficients were acceptable (.2 – .8), apart from indices in the Naming task and Verbal fluency task. The test showed very high reliability scores (α = .949), that were also satisfactory to high in the subscales of the test (ranging from .74 - .92) apart from the Naming (α = .65) and Verbal fluency (α = .50) scales. The test-retest reliability showed consistent results (r = .975). . Overall, the results from the pilot study show acceptable psychometric properties; however, two of the subscales should be revised. The pilot study should be continued and criterion validity tested.
