- FOODLIT-PRO: conceptual and empirical development of the food literacy wheelPublication . Rosas, Raquel Alexandra Ferreira; Pimenta, Filipa; Leal, Isabel Pereira; Schwarzer, RalfPursuing food systems' sustainability is crucial. Given the risk constituted by unhealthy diets, scarce research on food-related adjacent fields, and inconsistency across food literacy conceptualizations, this study aims to explore the constructs' definition and develop a conceptual and empirical framework of food literacy. A quantitative approach was taken on previously obtained qualitative outcomes from 30 interviews with experts from food-related fields. Food literacy was defined by a four-dimension model: Cooking Skills, Preserve and Analyse, Choice and Acquisition, Search and Plan. The framework Food Literacy Wheel integrates the construct definition, food literacy determinants (Internal, External) and influential factors (Nutritional, Psychological, Health, Learning Contexts, Policy, Industry, Sustainability, Social and Cultural). Allowing a broader perspective of food literacy within major food systems, this study contributes with new insights for future instruments and interventions, paving the way to develop/implement food literacy-related multi-sectorial and multilevel actions.
- Foodlit-pro: Food literacy project food literacy conceptualisation, assessment, and intervention with portuguese adultsPublication . Rosas, Raquel Alexandra Ferreira; Leal, Isabel Pereira; Pimenta, Filipa; Schwarzer, RalfIndividuals’ food-related education and empowerment is crucial not only to transform knowledge, competencies, and behaviours towards healthier and more sustainable food choices, but also to provide for skills that allow consumers to successfully navigate within food systems. The central aim of this dissertation was to contribute to further advancements in the field of food literacy by exploring its conceptual understanding, facilitate its assessment, and developing a theory-supported intervention. To this end, we developed a mixed-methods and sequentially designed project entitled ‘FOODLIT-PRO: Food Literacy Project’ that comprises three stages described in five chapters. Presented in chapters 2 and 3, Stage 1 demonstrated a wider outlook on the comprehension of food literacy, providing for a conceptual and empirical framework with a multidimensional definition of the construct, a characterisation of its determinants, and the identification of inter-sectorial fields of action. Described in chapter 4, Stage 2 allowed to translate the multifaceted conceptualisation of food literacy into a quantitative assessment tool, providing for an adaptable and validated measure to assess food literacy, its determinants, and influential factors in Portuguese adult samples. Presented in chapter 5 and 6, Stage 3 enabled the first known mapping of food literacy content into digitally delivered behaviour change techniques and allowed to verify the theoretical suitability of the Health Action Process Approach in predicting food literacy outcomes. These findings suggest that a broader approached should be taken when striving to promote food literacy, acknowledging the impact of surrounding areas and identified determinants. Emphasising the synergy between consumers’ food literacy and wider fields of action, the FOODLIT-PRO underlines the need to consider multidisciplinary approaches towards global food-related sustainability.
- The perceived consequences and self-concept of a successful weight loss – A qualitative studyPublication . Rosas, Raquel Alexandra Ferreira; Pimenta, FilipaA obesidade e a perda de peso implicam gerir percepções face à imagem corporal e lidar com padrões sociais. A investigação mostra que o excesso de peso e a obesidade têm impacto negativo na saúde física e no estado psicológico. A imagem corporal compreende o eixo atitudinal, que inclui a componente avaliativa e de investimento, e o eixo da auto-percepção. Sendo um conjunto de generalizações cognitivas, o auto-conceito inclui percepções específicas sobre o indivíduo em contextos particulares. Sendo que a qualidade da imagem corporal afecta a auto-estima, é pertinente o estudo do auto-conceito na experiência de perda de peso. Pretende-se avaliar de forma qualitativa as consequências percebidas e o auto-conceito, e desenvolver modelos explicativos (análise de correspondência múltipla). Foram entrevistados trinta participantes que realizaram uma perda de peso bem-sucedida (perda mínima de 7% do peso inicial e manutenção mínima de 12 meses). O conteúdo das entrevistas foi transcrito e submetido a análise temática e de conteúdo. As consequências percebidas organizam-se num modelo de três factores (Crescimento pessoal/Adversidades sociais, Imagem corporal/Benefícios sociais, e Bem-estar físico/emocional), compreendendo consequências como problemas relacionais e bem-estar/felicidade. Também o auto-conceito se organizou num modelo de três factores (Investimento eficaz/Auto-estima equilibrada, Ambivalente, e Aceitação positiva/Foco), incorporando auto-conceito físico e da personalidade explícita. Incluir em igual proporção ambos os géneros e utilizar entrevistas gravadas são vantagens que destacam a contribuição da investigação. O estudo amplifica o conhecimento das consequências percebidas e do auto-conceito, no contexto de uma perda de peso bem-sucedida. A análise retrospectiva é considerada uma limitação.
