[email protected]. PERSONALITY CHANGE IN EMERGING AND YOUNG ADULTHOOD 2 Abstract Early adulthood is a time of substantial personality change characterized by large inter- individual diversity. To investigate the role of age in this diversity, the present study examined whether emerging adults differ from an older group of young adults in their Big Five personality development. By means of multi-group latent change modelling, two groups of 16- to 19-year-olds (n = 3,555) and 26- to 29-year-olds (n = 2,621) were tracked over the course of four years and compared regarding four aspects of personality change: Mean-level change, rank-order change, inter-individual differences in change, and profile change.
