Preliminary psychometric validation data for a non-clinical South African sample using a neuroscience-based computerized battery

Normative psychometric test data for computerized neuro-cognitive batteries are scarce in the South African testing literature. The research explores the psychometric test properties of a computerized neuropsychological test battery in a non-clinical South African sample. A non-experimental correlational design was employed to collect data (N=594) and assess internal consistency indices on a number of executive and emotions tasks. The study also investigated the potential effect that certain socio-demographic factors may have on neuropsychological performance indicators and included mother’s education, father’s education, language used in high school, home language and quality of education. In keeping with current research it was found that even though socio-demographic factors do play a role in test performance, the psychometric properties of the battery remain consistent across different groups and further research utilising this tool is encouraged as the battery evidences construct validity.Keywords: Neuropsychology, computerized, psychometric, tool, South Africa
