Abstract
The recent rise in body dissatisfaction and weight bias has led to a call to the media to increase the diversity of their imagery, in efforts to challenge the thin-ideal. Therefore, this study aimed to evaluate the effects of both body diversity and thin-ideal interventions on health outcomes. Female participants (n = 160) were randomly allocated into an intervention group: body diversity; thin-ideal; control. They completed measures of body satisfaction, body compassion, internalisation of the thin-ideal, weight bias and behavioural intentions at baseline and post-intervention. The results showed significant differences between groups for weight bias and intentions to eat healthily. Specifically, those in the body diversity intervention group reported a greater reduction in weight bias compared to the other conditions. Further, those in the thin-ideal intervention group reported a greater increase in intentions to eat healthily compared to the other conditions. There were no differences between groups for body satisfaction, body compassion, internalisation of the thin-ideal and behavioural intentions to exercise and manage weight. In conclusion, exposure to body diversity images reduced weight bias whereas exposure to the thin-ideal promoted intentions towards healthy eating. These findings therefore offer empirical evidence for the impact of using different types of imagery to change different health outcomes.
