Assignment 2 2026
Unique number: 203365
Due Date: 19 June 2026
QUESTION 1 (2 ANSWERS PROVIDED)
1. Introduction
Van Wijk et al. (2024) conducted a South African psychometric study on the Montreal
Cognitive Assessment test, commonly known as the MoCA. The study is important because
Theme 1 explains that psychological measures must be evaluated according to their
purpose, constructs measured, norm group, validity, reliability and fairness before they are
used with a client or group (UNISA, 2026). This is especially important in South Africa, where
language, education and culture may influence test performance.
2. Aim of the study and description of the instrument
2.1 Aim of the study
The main aim of Van Wijk et al. (2024) was to replicate and extend earlier South African
research on the MoCA by giving a fuller description of its psychometric properties in a South
African workplace sample.

Van Wijk et al. (2024) conducted a South African psychometric study on the Montreal
Cognitive Assessment test, commonly known as the MoCA. The study is important

2. Aim of the study and description of the instrument
2.1 Aim of the study
The main aim of Van Wijk et al. (2024) was to replicate and extend earlier South
African research on the MoCA by giving a fuller description of its psychometric
properties in a South African workplace sample. The study focused on
neurocognitively healthy working adults who reported good English proficiency, and it
also compared them with a smaller group diagnosed with mild neurocognitive
disorders. The authors examined scale descriptions, structural validity, discriminant
validity and the possible use of grey-zone thresholds instead of relying only on one
universal cut-off score (Van Wijk et al., 2024).
2.2 Description, purpose and constructs measured
The MoCA is a brief cognitive screening test used to identify possible mild
neurocognitive impairment. It is not a full diagnostic assessment, but it helps to
identify people who may need further assessment. The test has a maximum score of
30, and the traditional cut-off score of below 26 has often been used to indicate
possible cognitive impairment (Van Wijk et al., 2024). In terms of Theme 2, the MoCA
falls under measures of cognitive functioning because it assesses mental
performance across specific cognitive areas (UNISA, 2026). The constructs
measured by the MoCA include visuospatial ability, executive functioning, attention,
language, memory and orientation (Van Wijk et al., 2024).
