The impact of an implicit manipulation of self-esteem on body dissatisfaction.

BACKGROUND AND OBJECTIVES Given the theoretically postulated causal pathway from low self-esteem on body dissatisfaction, the aim of the present study was to experimentally test this linkage before and after a mirror exposure in body dissatisfied females. METHOD Thirty-six women with high body dissatisfaction (HBD) and 39 women with low body dissatisfaction (LBD) received either a positive or a negative implicit manipulation of self-esteem and participants' actual body dissatisfaction and negative emotions were assessed (T1). Following that, they underwent a one minute mirror exposure and actual body dissatisfaction and emotions were assessed once more (T2). RESULTS In the HBD group no effects of the self-esteem manipulation were found prior to the mirror exposure. However, the negative manipulation of self-esteem led to a significant increase of body dissatisfaction over the course of the mirror exposure. The positive manipulation of self-esteem did not decrease body dissatisfaction over the course of the mirror exposure. No effects of self-esteem on body dissatisfaction were found in the LBD group. LIMITATIONS Formal eating disorder diagnosis in study participants was not established. Therefore, the extension of the results to an eating disordered population is recommended. CONCLUSIONS The results yield evidence of a close linkage between negative self-esteem and body dissatisfaction in individuals high on body dissatisfaction. Consistent with cognitive theories, this link is only apparent when shape and weight schemas are activated, e.g. by the confrontation with one's own body.
