Resumen

DANILLA E, Stefan et al. Development and testing of an instrument to assess body shape related quality of life. Rev Chil Cir [online]. 2015, vol.67, n.5, pp.493-505. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262015000500006.

Background: The assessment of patient satisfaction and quality of life after body remodeling surgery is important. Aim: To develop and assess a self-report instrument to evaluate the results of bariatric and body remodeling surgery. Material and Methods: A three phase methodology was used. In phase 1, literature was reviewed and in depth interviews to patients were carried out, creating a preliminary instrument that was applied to 1,340 patients in phase 2. In phase 3, the final assessment of the instrument was performed, applying it to 34 patients. The psychometric properties of the in instrument were evaluated. Results: The instrument has four domains (satisfaction with abdomen, sexual life, self-esteem and social life and psychological symptoms) and 20 items. Its score ranges from 20 (worst) to 100 (better). Response rate was 100%, internal reliability was 93% and test-re test concordance was 98%. Body shape related quality of life was significantly higher in men than in women. It decreases with age and with increasing body mass index. Patients subjected to bariatric surgery had lower scores than patients subjected to esthetic surgery. In the postoperative period, the score improved by 21.9 ± 16.9 points. Conclusions: The instrument developed can reliably measure quality of life associated with body shape.
