A bidirectional examination of expressed emotion among families of adolescents with bulimia nervosa.

ABSTRACT: The purpose of this paper was to examine expressed emotion (EE) measured from adolescents with bulimia nervosa (BN) toward their parents, in addition to measuring EE from parents toward patients.Fifty-four adolescents and their parents who were receiving treatment for BN participated in a videotaped family interview, from which ratings of EE were made.Parent and patient scores were highly correlated. Four family profiles were created (Low Patient EE/Low Parent EE; High Patient EE/High Parent EE; Low Patient EE/High Parent EE; High Patient EE/Low Parent EE) to determine whether the match between parent and patient EE was related to treatment outcome. The Low Patient EE/Low Parent EE group demonstrated the greatest reduction in purging from baseline to end-of-treatment; the High Patient EE/Low Parent EE group showed the smallest reduction in purging.EE has historically been rated from relatives toward patients, but patients' own EE may also be related to treatment outcome.

Project description:ObjectiveThe authors examined functional activity in the frontostriatal systems that mediate self-regulatory capacities and conflict resolution in adolescents with bulimia nervosa.MethodFunctional magnetic resonance imaging was used to compare blood-oxygen-level-dependent response in 18 female adolescents with bulimia nervosa and 18 healthy female age-matched subjects during performance on a Simon spatial incompatibility task. Bayesian analyses were used to compare the two groups on patterns of brain activation during correct responses to conflict stimuli and to explore the effects of antecedent stimulus context on group differences in self-regulation and conflict resolution.ResultsAdolescents with and without bulimia nervosa performed similarly on the task. During correct responses in conflict trials, frontostriatal circuits-including the right inferolateral and dorsolateral prefrontal cortices and putamen-failed to activate to the same degree in adolescents with bulimia nervosa as in healthy comparison subjects. Instead, deactivation was seen in the left inferior frontal gyrus as well as a neural system encompassing the posterior cingulate cortex and superior frontal gyrus. Group differences in cortical and striatal regions were driven by the differential responses to stimuli preceded by conflict and nonconflict stimuli, respectively.ConclusionsWhen engaging the self-regulatory control processes necessary to resolve conflict, adolescents with bulimia nervosa displayed abnormal patterns of activation in frontostriatal and default-mode systems. Their abnormal processing of the antecedent stimulus context conditioned their brain response to conflict differently from that of healthy comparison subjects, specifically in frontal regions. It is suspected that functional disturbances in frontal portions of frontostriatal systems may release feeding behaviors from regulatory control, thereby perpetuating the conflicting desires to consume fattening foods and avoid weight gain that characterize bulimia nervosa.
