Body image dissatisfaction is prevalent among college women and has been linked to problems such as eating disorders, depression, anxiety, and overall poorer quality of life (Pearson, Heffner, & Follette, 2010). Therefore, interventions to reduce body dissatisfaction in college settings are valuable. Of the various interventions targeting body dissatisfaction among college women, dissonance-based programs have consistently been the most effective (Stice & Presnell, 2007). However, Acceptance and Commitment Therapy (ACT) has recently demonstrated success in treating body image concerns (Pearson, Follette, & Hayes, 2012; Pearson et al., 2010). Studies indicate that ACT has reduced body dissatisfaction in an individual therapy format (Pearson et al., 2010) as well as in a 1-day workshop for adult women (Pearson, 2012). However, its effectiveness as a short-term group intervention for body-dissatisfied college women has yet to be compared with another empirically supported program.

520 $a Body image dissatisfaction is prevalent among college women and has been linked to problems such as eating disorders, depression, anxiety, and overall poorer quality of life (Pearson, Heffner, & Follette, 2010). Therefore, interventions to reduce body dissatisfaction in college settings are valuable. Of the various interventions targeting body dissatisfaction among college women, dissonance-based programs have consistently been the most effective (Stice & Presnell, 2007). However, Acceptance and Commitment Therapy (ACT) has recently demonstrated success in treating body image concerns (Pearson, Follette, & Hayes, 2012; Pearson et al., 2010). Studies indicate that ACT has reduced body dissatisfaction in an individual therapy format (Pearson et al., 2010) as well as in a 1-day workshop for adult women (Pearson, 2012). However, its effectiveness as a short-term group intervention for body-dissatisfied college women has yet to be compared with another empirically supported program.
520 $a The present study sought to determine whether an ACT intervention is as effective as a dissonance-based intervention in reducing body dissatisfaction for a sample of college women. Undergraduate women with high levels of body dissatisfaction were randomly assigned to participate in an ACT intervention, a dissonance-based intervention, or an expressive writing control condition. Each intervention consisted of four sessions and was conducted in small groups for one hour per week. Self-report measures of body dissatisfaction and body image avoidance were administered at pre-intervention, post-intervention, one-month follow-up, and two months follow-up.
520 $a It was hypothesized that both the ACT and dissonance-based interventions would be superior to an expressive writing control condition in reducing body dissatisfaction as well as body image avoidance. However, the mechanisms of action for the two intervention conditions were expected to be different. Specifically, it was predicted that change in body image outcomes for the ACT condition would be associated with an increase in psychological flexibility, while this would not be the case for the dissonance and control condition. In addition, change in body image outcomes for the dissonance-based condition would be associated with a decrease in thin-ideal internalization, while this would not be the case for the ACT and control conditions. Thus, when compared with the control condition, it was expected that thin-ideal internalization would mediate the effect of the dissonance intervention on body image outcomes, and that psychological flexibility would mediate the effect of the ACT intervention on body image outcomes.
520 $a In general, the findings did not support the hypotheses. Neither the ACT nor dissonance-based intervention demonstrated any significant effects on body image outcomes compared to the control condition at post-test nor at follow-ups. Notably, however, there were downward trends in body dissatisfaction observed during the course of the ACT and dissonance-based interventions that were not present for the control condition. Although the dissonance-based intervention did succeed in decreasing thin-ideal internalization, these changes did not produce significant effects on body image outcomes, failing to support the predicted mediation model. Further, the ACT intervention was not associated with greater changes in psychological flexibility compared to the control condition, contrary to hypotheses. Finally, no differences were observed when the two intervention conditions were directly compared. Considering this study's mixed findings, future studies should be conducted to further assess the value of both body image interventions among college women.
