Dissonance-based eating disorder program reduces cardiac risk: A preliminary trial.

Abstract

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.

Meta-analytic review of dissonance-based eating disorder prevention programs: Intervention, participant, and facilitator features that predict larger effects

“…This might be interpreted as providing additional support for the intervention theory for dissonance-based eating disorder prevention programs because the intervention activities center on exploring the costs of pursuing the thin ideal. Table 2 reveal that the trials that observed the largest effects (d > .70) for eating disorder symptoms, arguably the most critical outcome, emerged for the prevention programs evaluated by Atkinson and Wade (2016), Green et al (2016), Green, Willis et al (2017), Krishna (2011), Machin (2008), Mitchell et al (2007), and Rohde et al, 2014) relative to minimal intervention control conditions. Given that the studies by Machin, Mitchell, and Green, and Rohde evaluated interventions that added unique exercises to the standard Body Project the pattern of findings suggest that these versions of dissonance-based eating disorder prevention programs might be good candidates for implementation.…”

“…It is important to acknowledge that some participants who enroll in body acceptance eating disorder prevention programs due to body image concerns also have threshold or subthreshold eating disorders , which blurs the line between selected and indicated prevention. Further, it is possible that effects for dissonance-based eating disorder prevention programs will be even larger if they are implemented in an indicated fashion to young women with subclinical eating pathology versus when implemented universally to unselected populations, but only two trials evaluated a dissonance-based eating disorder prevention program when delivered in an indicated fashion (Green et al, 2016;Green et al, 2018), preventing us from comparing the effects sizes from indicated versus selective and universal dissonance-based prevention programs. An added benefit of this approach is that the intervention can be described as a body acceptance class, which facilitates recruitment.…”

A Controlled Randomized Preliminary Trial of a Modified Dissonance‐Based Eating Disorder Intervention Program

“…Participants came to the laboratory at each assessment period to have their height, weight, and cardiovascular function assessed. Cardiovascular results are reported in a separate paper (see Green et al., ).…”

Prevention of eating disorders: current evidence-base for dissonance-based programmes and future directions

“…Finally, there is recent trial evidence that an Internet version of the noted Body Project showed a significant reduction in ED symptoms and body mass index relative to educational video control conditions and educational brochure through a 1-year follow-up [84]. Given accumulated evidence [25,28,[32][33][34][35][36][37][38][39][40][41] that the Body Project yields greater reductions in factors that greatly increase the likelihood of both obesity and EDs (i.e. negative affect and body dissatisfaction) [72][73][74][75][76][77][78][79][80], it would be useful for future research to test the potential of this Internet version of the Body Project to reduce future ED and obesity onset.…”

“…[34][35][36]), though not all of these trials targeted females with body image problems/ concerns. Moreover, the Body Project decreased ED symptomatology and electrocardiogram-assessed cardiac risk indices among females with sub-clinical and clinical EDs [37], which is relevant since cardiac problems are among the leading mortality causes among such people. Hence, the Body Project has demonstrated efficacy when implemented (a) universally to females who were not screened for body image problems, (b) selectively to females with body image concerns, and (c) in an indicated fashion to females with ED symptomatology.…”
