Chapitre sur l'estime de soi

Je vais avoir une nouvelle publication à mon CV. Jacob a été invité à rédiger un chapitre pour un livre sur l'estime de soi, et l'éditrice a accepté le résumé de chapitre que nous avons proposé. Nous devons rédiger le chapitre d'ici le 15 juin 2011. Voici le titre et le résumé du chapitre:

The epidemiology of sex differences in the expression of self-esteem: A test of two explanatory models

Females report lower self-esteem than males across cultures and at early stages of child development, suggesting that the differences are rooted in natural biological processes. Scientists have used two general models to explain the epidemiology of these differences. A disease-centered perspective characterizes the first domain of models. A corresponding thesis is that lower self-esteem in females is biologically maladaptive and thus the result of vulnerability in the form of disregulated cognitive processing or heightened exposure to external stressors. A functional perspective characterizes the second domain of models. One thesis asserts that the expression of both high and low self-esteem each have adaptive social communicatory properties and that differential expression reflects specialized expressive styles for regulating sex-typical peer relationships. We examined aspects of these alternative models using a college sample of healthy adults (n = 808, Mean age = 22.2, SD = 4.9). Sex differences emerged for internalizing behaviors including self-esteem, as well as relationship dynamics, social communication styles, and reported trauma. As predicted by the functional perspective, sex-typical (feminine) expressive biases mediated the relations between (female) sex and various internalizing behaviors including self-esteem. In contrast, trauma experiences only mediated sexually-differentiated emotional pain. Overall, the findings support both evolutionary and developmental models for understanding the epidemiology of sex differences in self-esteem. Implications for the distinction between explicit and implicit self-esteem and future directions for research on subjective well-being are discussed.
