Abstract
We conducted a randomized, controlled preliminary trial to examine the effect of a dissonance-based eating disorder program on eating disorder symptoms and cardiac risk indices in a community sample of women with subclinical and clinical symptoms (N = 47), examining the efficacy of the program in both the indicated prevention and treatment realms.
Eating disorder symptoms, body mass index, and biomarkers of cardiac risk were examined in dissonance and assessment-only control conditions at baseline, postintervention, and 2-month follow-up. Specifically, we assessed mean R wave amplitude, QT interval length, vagal tone (high frequency spectral power of heart rate variability), and sympathetic tone (low/high frequency spectral power ratio) via electocardiography (ECG) at each assessment period.
We predicted a statistically significant 2 (condition: control, dissonance) × 3 (time: baseline, postintervention, 2-month follow-up) interaction in the mixed factorial MANOVA results. Results confirmed this hypothesis. Eating disorder symptoms and cardiac risk indices decreased significantly among participants in the dissonance condition at postintervention and 2-month follow-up compared with baseline.
Results provide support for the efficacy of a dissonance-based program in the reduction of eating disorder symptoms and cardiac risk indices among women with subclinical and clinical eating disorder symptoms. Findings establish the efficaciousness of this dissonance-based approach in the indicated prevention and treatment realms and establish its efficacy in reducing cardiac risk indicators.
