Development and validation of the Dutch brief form of the Multidimensional Personality Questionnaire (MPQ-BF-NL)

This study describes the development and psychometric properties of the Dutch brief form of the Multidimensional Personality Questionnaire (MPQ-BF-NL). Representative samples from the Netherlands (N = 1,055) and the United States (N = 1,153) and a Dutch student sample (N = 987) were used for development, cross- and external validation, respectively. The authors' strategy for item selection and scale validation replicated the development of the U.S. brief form (MPQ-BF). Internal consistencies were generally good and comparable to the U.S. version, as were correlations with the U.S. full-length scales and higher order structure. Moreover, convergent and divergent patterns were consistent with prediction, with Positive Emotionality related to social and activating behavior, Negative Emotionality to anxiety, and Constraint to reversed impulsivity and externalizing behaviors. In sum, the MPQ-BF-NL provides the Dutch-Flemish language area with a personality inventory well suited for both psychopathology research and clinical practice and offers new opportunities for fundamental and cross-cultural studies on personality.

Goal and Personality Trait Development in Emerging Adulthood

The present research examined continuity and change in the importance of major life goals and the relation between change in goals and change in personality traits over the course of college (N = 298). Participants rated the importance of their life goals 6 times over a 4-year period and completed a measure of the Big Five personality traits at the beginning and end of college. Like personality traits, life goals demonstrated high levels of rank-order stability. Unlike personality traits assessed during the same period and in the same sample, the mean importance of most life goals decreased over time. Moreover, each goal domain was marked by significant individual differences in change, and these individual differences were related to changes in personality traits. These findings provide insights into the relatively unstudied question of how life goals change during emerging adulthood.
