Self-other positioning in obesity: A pilot study using repertory grid technique

Self-other positioning was investigated in a group of obese youths in order to empirically test the clinical hypothesis - based on the constructionist theory of Family Semantic Polarities - that obese people are affected by a negative self-perception and low self-esteem. Repertory grid technique was used with 30 participants (15 obese-overweight and 15 control) to elicit and compare their personal constructs and assess, via ad hoc measurement indices, the positions they assigned to the self and significant others in relation to these constructs. The results confirmed the research hypotheses, with obese subjects displaying a tendency to position both self and others at the negative pole of bipolar constructs and reporting greater self-ideal discrepancy. These findings and their limitations are discussed in relation to their clinical applications and in light of the methodological issues arising from the study. © Castiglioni et al.
