Akzeptanzfördernde Intervention und kurzes internetbasiertes Selbstwerttraining bei der Körperdysmorphen Störung
摘要
The treatment rates of body dysmorphic disorder (BDD) are low due to various perceived barriers to treatment. Cognitive behavioral internet-based interventions are effective but present challenges regarding acceptance and adherence. This study therefore evaluates the use of an acceptance-facilitating intervention (AFI) and the effectiveness of a brief internet-based self-esteem training as a low-threshold and resource-oriented approach.
MethodA total of 46 adults with relevant symptoms of BDD (n = 17 diagnosed with complete BDD) either received an AFI (educational video) or were randomly assigned to a control group. Afterwards, all participants were offered a 2-week internet-based self-esteem training.
ResultsThe AFI increased the acceptance of internet-based interventions and related constructs such as credibility compared to the control group; however, no group differences were found in participation rates and the number of active training days. The self-esteem training not only improved the state of self-esteem but also reduced the BDD symptoms. The participation rates and adherence were overall high. This pattern was mostly confirmed in the subsample diagnosed with BDD.
ConclusionThe AFI represents an economical approach to increase acceptance and expectancy toward internet-based interventions in BDD. The high acceptance of the self-esteem training suggests that a resource-oriented intervention can help overcome perceived barriers to treatment. The clinically relevant improvement in symptoms achieved by addressing self-esteem highlights its central role in BDD. The brief internet-based self-esteem training could also serve as a low-threshold intervention to improve treatment rates in other body image disorders.
