Abstract

Body image is a multidimesional construct including both perceptual body size distortion and body dissatisfaction. In this study a comparison between the adjustment and staircase methods has been carried out on a sample of 137 participants (60 males and 77 females) in order to investigate body size distortion (both side and frontal profile). Concerning the cognitive component, questionnaires have been administred to assess body dissatisfaction. Results show that (i) the staircase method detects a greater distortion than adjustment method, (ii) in males sample, side profile has a greater distortion than frontal profile, and (iii) perceptual body size distortion and body dissatisfaction seem not to be related.
