Despite the array of neuropsychological tests available, these assessments are largely made and developed for use in WEIRD (western, educated, industrialized, rich, democratic) societies (Fernandez, 2019; Ponsford, 2017). The Multicultural Neuropsychological Scale (MUNS) was developed with underrepresented groups in mind as a universally valid neuropsychological assessment which can be used across cultures and adapted to different languages. To assist with the validation of the MUNS as a cross-cultural instrument, investigators administered the MUNS to a cognitively 'healthy’ college-aged population in the United States as a means of collecting normative data. Results were compared to samples taken from an Argentine university, Universidad Catelica de Cerdoba, and combined with another American university, Marymount Loyola University. The goal of this comparison was to provide evidence supporting the validity of the MUNS as a universal, cross-cultural neuropsychological assessment battery.

Students from James Madison University (JMU) in Harrisonburg, Virginia (N = 24, Age = 20.083 1.93, Female = 87.5%) were recruited via a campus-wide email. Students who met inclusionary criteria were selected for MUNS administration. Students completed a background questionnaire and effort measure (REY-15; Rey, 1964) before completing the MUNS battery, consisting of eight subtests with four delayed trials. Descriptive statistics of the group were assessed, and one-way ANOVAs were conducted on the various subtests to determine whether differences exist between the American and Argentine samples.

No significant difference between groups was found for seven subtests. A difference existed on the Attention subtest between the American (f (1, 106) = 45.409, p < .001).

The results show support for the cross-cultural validity of the MUNS. The only significant difference was found in the Arrows (Old) subtest. This is in alignment with previous administrations of the MUNS (Fernandez et al., 2018). Further studies are needed to assess potential bias within this subtest, as well as to pursue comparison studies for the New Arrows subtest administered within this USA sample. The present findings provide further evidence that the MUNS can be applied as a neuropsychological assessment across a variety of populations.
