Research examining the relationship between self-esteem, body image attitudes and eating behaviours remains unclear. Some argue that this lack of clarity is due to the non-specificity involved in measurement of self-esteem in relation to body attitudes and eating behaviours. The current study addresses this issue by exploring the relationship between self-esteem and specific contingencies of self-worth to body image dissatisfaction and dysfunctional eating behaviours in a non-clinical sample of 59 young adult females (age range 21 to 35 years; M = 25, SD = 4.3). The findings indicate that there is a strong positive relationship between external contingencies of self-worth and global self-esteem as measured by the Rosenberg Self Esteem Scale. Moreover, those women who have a high investment in external contingencies of self-worth reported higher levels of body-image dissatisfaction and dysfunctional eating behaviours than those with a low investment in these contingencies. The findings suggest that reducing one's over investment in aspects of self-worth that are driven by external factors is more relevant than attempting to boost overall self-esteem, in reducing vulnerability to socio-cultural influences. Further research, exploring the conceptual underpinnings of the construct of self-esteem in relation to body image and eating behaviours is recommended.
