Avaliar as propriedades psicométricas do CASQ quando aplicado a amostra de pacientes oncológicos ingleses e verificar sua invariância frente à amostra brasileira. Apresentar proposta de avaliação do impacto da doença e do tratamento na qualidade de vida de pacientes oncológicos. Estimar o consumo de energia e de macronutrientes de pacientes com câncer e sua relação com características demográficas e clínicas, e estimar a contribuição da ingestão alimentar e do apetite no impacto na qualidade de vida de indivíduos com câncer. Métodos: Foram estimadas as validades de face, conteúdo e construto (fatorial e convergente). Para todos os modelos foi realizada análise fatorial confirmatória (AFC) e utilizados os índices razão de qui-quadrado pelos graus de liberdade (χ2/gl), comparative fit index (CFI), goodness of fit index (GFI) e root mean square error of aproximation (RMSEA). A validade convergente foi analisada pela Variância Extraída Média (VEM). A Confiabilidade foi estimada por meio da Composta (CC) e pelo Coeficiente alfa de Cronbach (α). A invariância fatorial foi estimada por análise multigrupos (∆χ2). Para definir o melhor modelo foram utilizados os índices da teoria da informação (Akaike Information Criterion (AIC), Browne-Cudeck Criterion (BCC) e Bayes Information Criterion (BIC). Como instrumentos de medida utilizou-se o Cancer Appetite and Symptom Questionnaire (CASQ), Functional Assessment of Cancer Therapy - General (FACT-G), o European Organization for Research and Treatment of Cancer - Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) e o... / Objectives: to perform a cultural adaptation of the Cancer Appetite and Symptom Questionnaire (CASQ), into Portuguese, and evaluate its psychometric properties on a sample of Brazilian cancer patients. Evaluate the psychometric properties of CASQ when applied to sample United Kingdom (UK) cancer patients and check their invariance front of the Brazilian sample. To present a proposal for evaluating the impact of cancer and treatment on quality of life among cancer patients. To estimate the energy and macronutrient intakes of cancer patients and their relationship with the patients' demographic and clinical characteristics, and to estimate the contribution of food intake and appetite to the impact on the patients' quality of life. Methods: Face validity, content and construct (factorial and convergent) were estimated. For all models were performed confirmatory factor analysis (CFA) and the indices used chisquare ratio by degrees of freedom (χ2/df), comparative fit index (CFI) goodness of fit index (GFI) and root mean square error of aproximation (RMSEA). Convergent validity was analyzed by Average Variance Extracted (AVE). Reliability was estimated by the Composite Reliability (CR) and the Cronbach's alpha coefficient (α). The factorial invariance was estimated by multigrupos analysis (∆χ2). To define the best model we used the contents of the theory of information (Akaike Information Criterion (AIC), Browne-Cudeck Criterion (BCC) and Bayes Information Criterion (BIC). As measuring instruments used the Cancer Appetite and Symptom Questionnaire (CASQ), Functional Assessment of Cancer Therapy - General (FACT-G), the European Organization for Research and Treatment of Cancer - Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Food Frequency Questionnaire (FFQ). Statistical significance of causal paths (β) was analyzed using z-tests, and sample adjustment ...
