Psychodynamic approaches to the treatment of individuals with eating disorders are underrepresented in research and in academia. This will increasingly deprive patients of a viable therapeutic alternate to the dominant behavioral family-based models. As psychodynamic approaches may have unique benefits, there is value in resolving this loss. Recent models of dynamic therapies for eating disorders within modern, empirically-derived theory show promise for future psychodynamic viability. An attachment-focused approach targeting disordered attachment patterns that are common in individuals with eating disorders is a recent accomplishment. To complement this model, this paper proposes an approach for individuals with eating disorders that is hypothesized to target emotion regulation deficits that are also commonly found in individuals with eating disorders. Observed parallels between the implicit branch of the emotion regulation system and that of contemporary constructs of defense mechanisms guide this proposal. Developmental considerations reveal important connections between this biologically-based model and a two-person model based in attachment theory. In this way, this proposal offers a flexible psychodynamic approach that integrates with the existing literature. The approach is illustrated in case material from the treatment of an adolescent with anorexia nervosa and discussion follows.
