| Abstract: | Sociocultural models hypothesize causal paths in the development of eating disorders, yet few longitudinal studies have controlled for temporal stability, leaving open the question as to causality and the directionality of effects. In the present study, the authors tested portions of the socioculturally based dual-pathway model, specifically, the risk factor hypotheses that internalization of the thin ideal predicts body dissatisfaction, that body dissatisfaction predicts depressive affect, and that depressive affect predicts disordered eating. The authors also examined competing hypotheses (e.g., disordered eating predicts depressive affect) as well as the possibility of simultaneous relationships (i.e., variables would be related to one another within a time frame). The 6 models (3 cross-lagged and 3 simultaneous) were evaluated using 236 female freshmen who provided self-report data during their 1st semester in college and 6 months later. While controlling for temporal stability, structural equation modeling revealed that (a) internalization and body image each were related to the other across time; (b) body image was related directionally, but only in the simultaneous context, to depressive affect; and (c) depressive affect and disordered eating were related reciprocally and temporally to one another. Directions for future research and implications for intervention are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
