Obesity implies risks for physical and psychological health, impacting negatively on self-esteem. As an improvement strategy, weight loss often has an impact not only on body image but also on others domains of self-concept. Despite the extensive research on physical self-concept, the exploration of others self-concept's domains concerning a weight loss is scarce. This study aims to explore the spontaneous self-concept of a successful weight loss. Thirty men and women who achieved a successful weight loss (loss at least 7% of the initial weight and made a minimum maintenance of 12 months) were interviewed. The in-depth audio-recorded interviews were transcribed and analysed through content and thematic analysis (pluralistic analysis with inductive and deductive approaches), by a jury of psychologists. A quantitative exploration of the association between the emergent categories was made through a multiple correspondence analysis. An inter-rater agreement (Cohen's k) was substantial (.734). Self-concept established a three-factor model: 1) Effective investment/Balanced self-esteem, 2) Ambivalent, and 3) Positive acceptance/Focused, entailed domains such as self-esteem, physical, social, and explicit personality self-concept. The qualitative exploration of self-concept on a weight loss context contributes to engrossing the current literature. Emphasising that not only physical but also psychological aspects may be impacted in a successful weight loss process, this study highlights that negative self-representations must be attended in a clinical interventions' context.

AUTO-CONCEITO ESPONTÂNEO NUMA PERDA DE PESO BEM-SUCEDIDA-ESTUDO QUALITATIVO PLURALISTARESUMO: A obesidade implica riscos para a saúde, afectando negativamente a auto-estima. Como estratégia de melhoria, a perda de peso impacta não só a imagem corporal como também outros domínios do auto-conceito. Apesar da extensa investigação sobre o autoconceito físico, a exploração de outros domínios do auto-conceito relativamente a uma perda de peso é escassa. Este estudo tem como objectivo explorar o auto-conceito espontâneo de uma perda de peso bem-sucedido. Trinta homens e mulheres que fizeram uma perda de peso bem-sucedida (perda mínima de 7% do peso inicial e uma manutenção mínima de 12 meses) foram entrevistados. As entrevistas foram gravadas em audio, transcritas e analisadas através da análise de conteúdo e análise temática (análise pluralista com abordagens indutiva e Rua Jardim do Tabaco, 34, 1149-041 Lisboa, Portugal.
