Hough and colleagues’ (2001) narrative review summarized the published research exploring Latino/Hispanic-White group mean score differences on the Big Five personality factors. They also reported effect sizes for measures of the facet-level personality constructs of surgency (i.e., potency, dominance) for extraversion and achievement and dependability for conscientiousness. In general, ds were modest (with a few exceptions). For conscientiousness, they report d = 0.04 favouring Whites. On the facet of achievement, they report small differences that favour Latinos/Hispanics, d = 0.04. However, on the facet of dependability there were larger differences favouring Whites, d = 0.11.
For extraversion, the difference is near zero (d = 0.01), favouring Latinos/Hispanics. At the facet level, the difference is near zero (d = 0.01), again favouring Latinos/Hispanics. On the construct of adjustment (i.e., emotional stability or reverse-scored neuroticism) the difference is near zero (d = 0.01), also favouring Latinos/Hispanics. However, the differences favoured Whites on the dimensions of agreeableness (d = 0.06) and openness to experience (d = 0.10).
Foldes and colleagues (2008) expanded their meta-analysis and reported the following differences (unless otherwise noted, differences favour Latinos/Hispanics). For emotional stability, d = 0.03 with respective global measure, self-esteem facet measure, low anxiety facet measure and even-tempered facet measure ds of 0.04 (favouring Whites), 0.25, 0.25 and 0.09; for extraversion, d = 0.02 (favouring Whites) with respective global measure, dominance facet measure and sociability facet measure ds of 0.12, 0.04 (favouring Whites) and 0.16 (favouring Whites); for openness to experience, d = 0.02 (favouring Whites); for agreeableness, d = 0.05 (favouring Whites); for conscientiousness, d = 0.08 with respective global measure, achievement facet measure, dependability facet measure, cautiousness facet measure and order facet measure ds of 0.20, 0.10, 0.00 and 0.00. Again, while composite-level effect sizes are generally small and often close to zero, appreciable facet- level effect sizes emerge. Overall, while Big Five measures by and large demonstrate much lower Latino/Hispanic-White group mean score differences than do measures of cognitive ability, there is some variation in the size of these differences depending on the construct and whether one is looking at facet or global measures.
On measures of integrity, Hough and colleagues (2001) report that Latinos/Hispanics score higher than Whites (d = 0.14). In addition, it was found that Latinos/Hispanics also score higher than Whites (d = 0.56) on measures of social desirability. More recent primary research has confirmed this finding (e.g., Dudley, McFarland, Goodman, Hunt & Sydell, 2005).
