| Abstract | The purpose of the current study is to advance our understanding of the development of social anxiety -- with particular attention to humiliation anxiety and performance anxiety -- and social self-perception in maltreated and nonmaltreated comparison adolescents, and to provide prospective empirical evidence supporting a cognitive model of social anxiety. Specifically, the study aimed 1) to test mediation of social self-perception in the relationship between child maltreatment experience and social anxiety over time; 2) to understand the developmental trends of social anxiety and self-perception across age; 3) to investigate the impact of child maltreatment on the developmental trajectories of social anxiety and self-perception; 4) and to examine the longitudinal dynamic mechanisms between social anxiety and self-perception across age. This study was part of a larger longitudinal prospective study of the impact of maltreatment on the development of adolescents. The ethnically diverse sample consisted of 303 maltreated and 151 comparison children. Maltreated children were recruited from active cases in the Los Angeles County Department of Children and Family Services and the demographically similar comparison sample was recruited from the same zip-codes as the maltreated sample. The subjects were evaluated three times with 1-year interval. A series of longitudinal analyses techniques were used within a framework of Structural Equation Modeling including: a cross-lagged model, a latent growth curve model, and a univariate and a bivariate latent difference score model. The results supported full mediation of social self-perception between child maltreatment experience and social anxiety in adolescence. Child maltreatment experience predicated lower social self-perception which in turn predicted higher humiliation anxiety and performance anxiety at later time.; Social anxiety tended to decrease and social self-perception tended to increase with age, but there was no significant difference in developmental trend of social anxiety between the maltreated and the comparison adolescents. The results from the bivariate latent difference score models reveal that social self-perception is a leading factor influencing change in performance anxiety over time. The findings lend strong empirical support for a cognitive model of social anxiety in relations to self-perception. This study provides important empirical data that can be used to guide the development and provision of effective intervention for social anxiety and social self-perception in maltreated adolescents. |
