“…These results, and a quantity of other data, accompanied by our own observations, make it very unlikely that children younger than 12 years of age and scoring, say, less than 38 points on the SPM do not already have a personality structure or that it is very dissimilar to the adult structure. Existing data clearly indicate that the personality structure in early adolescence resembles that of adults in all five dimensions, at least when it is estimated by knowledgeable adults (Barbaranelli, Caprara, Rabasca, & Pastorelli, 2003;Markey et al, 2002;Mervielde et al, 1995). Accordingly, it is more likely that the fragility of the self-reported personality structure in 12-year-olds is caused by its introspective inaccessibility due to insufficient cognitive capabilities and verbal skills that are prevalent in this age group.…”
