Objective: A group dissonance-based eating disorder prevention program, in which young women critique the thin ideal, reduces eating disorder risk factors and symptoms, but it can be difficult to identify school clinicians with the time and expertise to deliver the intervention. Thus, we developed a prototype Internet version of this program and evaluated it in a preliminary trial. Method: Female college students with body dissatisfaction (N = 107; M age = 21.6 years, SD = 6.6) were randomized to the Internet intervention, group intervention, educational video condition, or educational brochure condition. Results: Internet and group participants showed greater pre-post reductions in eating disorder risk factors and symptoms than video controls (M ds = 0.47 and 0.54, respectively) and brochure controls (M ds = 0.75 and 0.72, respectively), with many effects reaching significance. Effects did not differ significantly for Internet versus group participants (M ds = -0.13) or for video versus brochure controls (M d = 0.25). Effect sizes for the Internet intervention were similar to those previously observed for group versions of this intervention. Conclusions: Results suggest that this prototype Internet intervention is as efficacious as the group intervention, implying that there would be merit in completing this intervention and evaluating it in a fully powered trial.

    • "eficacia de una intervención cognitiva breve con alumnado universitario de educación primaria ción breve (seis semanas). Investigaciones recientes corroboran la potencial eficacia de programas de duración limitada (Orejudo, Fernández-Turrado y Briz, 2012; Stice et al, 2012 ), siempre y cuando estos se encuentren focalizados en un ámbito o área determinada, como es el caso del presente estudio. Sin embargo, tradicionalmente la duración mínima recomendada para este tipo de intervenciones se ha situado en 10 semanas (Alfermann y Stoll, 2000). "

    ABSTRACT: The physical self-concept has shown its relation with different factors such as lifestyle, certain risk behaviors, and even with the development of eating disorders. Its relevance and contribution to general self-perception has led to investigation of the possibility of improving it. Traditional interventions based on exercise programs and physical activity tend to be effective, however its dissemination and distribution is limited. This study evaluates the effectiveness of a new intervention program implemented on physical self-concept from a cognitive perspective. Its features allow an individual self-application limited to six weeks. The participants' results (169 undergraduates, 22.5% male, 77.5% female, mean age 21.40 years in the experimental group, SD = 5.49, and 21.03 years of mean age in the control group, SD = 4.50) show statistically significant improvements in the scales of physical condition, general physical self-concept and general self-concept at the end of the application. The magnitude of those improvements is significant but low. These improvements are not reflected when the experimental group scores are compared to those of the control group. The possible reasons for those results are discussed, taking into account future designs to enhance the effectiveness of such interventions.

    • "It seems unlikely that differential clinical experience of facilitators explains the fact that the Body Project tends to produce larger effects than other eating disorder prevention programs, because numerous trials of other eating disorder prevention programs have often had graduate students or experienced clinicians deliver the interventions. Thus, while the acute effects from this trial suggested that the eBody Project produced effects that were similar in magnitude to the Body Project effects (Stice et al., 2012), results from the present report indicate that the group Body Project generally produces more clinically meaningful intervention effects that show greater persistence over time if delivered by experienced clinicians, but that the eBody Project produces effects that are similar to those observed by clinicians with less expertise. One potential explanation for why the effects for key outcomes such as thin-ideal internalization were weaker for the eBody Project versus the Body Project is that participants may feel greater public accountability when they critique the thin ideal in a group of peers, versus online, potentially because they continue to see these peers outside of the group setting or have the potential to do so, whereas they are more anonymous when they critique the thin ideal on the Internet.

    ABSTRACT: Objective: A group-based eating disorder prevention program wherein young women explore the costs of pursuing the thin ideal reduces eating disorder risk factors and symptoms. However, it can be challenging to identify school clinicians to effectively deliver the intervention. The present study compares the effects of a new Internet-based version of this prevention program, which could facilitate dissemination, to the group-based program and to educational video and educational brochure control conditions at 1- and 2-year follow-up. Method: Female college students with body dissatisfaction (n = 107; M age = 21.6, SD = 6.6) were randomized to these 4 conditions. Results: Internet participants showed reductions in eating disorder risk factors and symptoms relative to the 2 control conditions at 1- and 2-year follow-up (M -d = .34 and .17, respectively), but the effects were smaller than parallel comparisons for the group participants (M -d = .48 and .43, respectively). Yet the Internet intervention produced large weight gain prevention effects relative to the 2 control conditions at 1- and 2-year follow-up (M -d = .80 and .73, respectively), which were larger than the parallel effects for the group intervention (M -d = .19 and .47, respectively). Conclusions: Although the effects for the Internet versus group intervention were similar at posttest, results suggest that the effects faded more quickly for the Internet intervention. However, the Internet intervention produced large weight gain prevention effects, implying that it might be useful for simultaneously preventing eating disordered behavior and unhealthy weight gain.

    • "Consistent with the other applications of cognitive dissonance, it appears to be superior to the neutral or mindfulness approach and is associated with longer duration of positive effects.[70] It has also been delivered via the internet, with reported positive effects comparable to those seen with a face-to-face group intervention.[71] This, along with other internet-based interventions that report positive findings,[72] is encouraging and reflects a potential route by which eating disorder prevention can be disseminated in countries where mainstream prevention efforts are currently limited but where rapid modernization permits easy access to online material.

    ABSTRACT: Eating disorders are common, life-threatening conditions in Western countries, but until relatively recently they were regarded as uncommon in non-Western cultures. However, the prevalence of eating disorders in many of the more affluent non-Western countries is rising rapidly as community members, particularly young women, internalize the 'thin ideal' that has been widely promoted by the international media. This review discusses the factors involved in the development of eating disorders in non-Western settings with a particular emphasis on the influences of urbanization, modernization, Westernization, and the resulting changes in women's roles. The cognitive dissonance programs developed in Western countries that have proven successful in countering the negative effects of the thin idea are described and their potential application to East Asia and other non-Western countries are discussed.
