Question 1:
Montreal Cognitive Assessment (MoCA) – Sampling and Suitability in the South
African Context
Aim, instrument description, purpose and constructs measured
The Montreal Cognitive Assessment (MoCA) is a brief cognitive screening instrument
designed to detect mild cognitive impairment and early neurocognitive decline. It measures
multiple domains of cognitive functioning, including executive functioning, attention,
memory, language abilities, visuospatial skills, abstraction, and orientation. These domains
reflect higher-order cognitive processes required for independent daily functioning and are
often affected in the early stages of neurocognitive disorders.
In the South African context, the relevance of the MoCA lies in its application across
linguistically, culturally, and educationally diverse populations. Cognitive screening tools
developed in Western contexts often assume relatively uniform education levels, language
proficiency, and cultural familiarity with testing formats. In South Africa, marked differences
in schooling quality, multilingualism, and socioeconomic conditions influence cognitive test
performance independently of actual cognitive ability. This raises concerns about whether
the MoCA measures pure cognitive functioning or whether it is partially confounded by
contextual factors such as education and language (Van Wijk et al., 2024).
