The assessment of personality factors across 25 countries

The means for each scale score from the Eysenck Personality Questionnaire were compared individually and conjointly across 25 countries. Comparisons were carried out using coded difference scores, Pearson correlations, Euclidean distances, cluster analyses and non-metric multidimensional scaling. It was possible to compare the personality (as defined by the scale scores on E, N, P and L) of each country with all other countries, culminating in a one-dimensional non-metric scale of distances for both the male and female data from each country. The assumptions underlying the rationale of the measures used and the comparisons undertaken are briefly discussed.
