Media images of unrealistic beauty have been identified as a determinant of women's body dissatisfaction. This experimental study aims to explore whether the negative impact of such images could be reduced by a one-time educational intervention consisting of a presentation and discussion, teaching women to be critical of media images.

Female psychology students (n=176) from a university in the UK were randomly assigned to the control or intervention group and completed measures of body dissatisfaction after being challenged by images of the perfect female body. Follow up data were collected four weeks later.

The results suggested that the intervention had no immediate buffering effect on body dissatisfaction but participants in the intervention group showed a long-term improvement for confidence, attractiveness and body-parts dissatisfaction.

This one-time intervention could be used to protect young women against the detrimental impact of media images in the longer term.

This study provides an evidence base for the use of an educational intervention for young people in schools and colleges.
