Method: descriptive, exploratory and correlational investigation. Forty-seven adolescents participated in an obesity consultation in Portugal. Data obtained between May and September 2018, through a questionnaire consisting of the University of Rhode Island Change Assessment Scale that evaluates motivation for change, and the Contour Drawing Rating Scale that evaluates satisfaction with body image. Results: prevalence of females n=33 (70.2%); mean age: 15.51 years. Mean body mass index of 29.05 kg/m2.
