摘要：Body image is a multifaceted construct involving several dimensions. Itis socially defined and the way we feel about our own image influences various aspects of our lives. Dozens of scales have been developed to measure the perception of body image,however,they are made up of contoured images whichrepresent bodies from the leanest to the fattest,not contemplating silhouettes with more apparent muscle mass. Thus,the aim of this study is to validate psychometric qualities of the silhouette scale proposed by Damasceno (2004) for measuring body image in adults. The sample consisted of59 students of both genders from the Department of Physical Education in a University. Anthropometric measurements followed the recommendations of ISAK and in order tostandardize the measurements the participants were asked: “What figure best represents your body?” (actual silhouette);“What figure represents the best the body you would like to have?” (ideal silhouette). The second visit occurred in an interval of 15 days afterthe first one and the same questions were then asked to them.The instrument’s validity was calculated from the correlation coefficient with second-order polynomial adjustment of SA in relation to BMI (r = 0.77,p = 0.001) and G% (r = 0.58,p = 0.001). The Intraclass Correlation Coefficient (ICC) for the test and re-test ofthe Actual Silhouette (AS)and Ideal Silhouette (IS)werecalculatedfor reliability,with values of 0.94 and 0.93,respectively. The effect size was also calculated,showing a trivial result for SA and small for SI. The presented instrument has good psychometric qualities and can generally be applied to the adult Brazilian population.
