background Individuals with eating disorders tend to internalise their anger and aggression excessively. However, an evidence-based intervention, targeted on this persistent issue, was missing until now. Therefore, a body and movement oriented intervention was developed, which supports patients to reframe and redirect anger and aggression against the destructive influence of the eating disorder.
aim To study the effectiveness of the aggression regulation intervention.
method The intervention was tested in a first randomised controlled trial (rct) in an outpatient setting and in a two-center rct in a multidisciplinary day hospital setting. Coping with anger was measured by the Self-Expression and Control Scale (secs). Eating disorder pathology was measured by the Eating Disorder Examination Questionnaire (ede-q).
results Both rcts delivered first evidence for the brief body and movement oriented intervention to reduce excessive anger internalisation in individuals with eating disorders. Moreover, in the outpatient trial the eating disorder pathology was significantly more reduced in the intervention group compared to the control group.
conclusion There is first evidence for the effectiveness of a body and movement oriented approach of reducing excessive anger internalisation in individuals with eating disorders.
