Resumo

Antecedentes: O câncer é um problema de saúde pública, uma das variáveis psicossociais relacionadas a essa doença é o estresse, portanto, é necessário ter uma escala que meça o estresse na população hispânica com câncer. Objetivo: Determinar as propriedades psicométricas da Escala de Medição do Estado Atual (MOCS) em pacientes mexicanos com câncer. Método: Desenho do estudo: transversal, instrumental, não experimental. Participaram 197 pacientes com idades entre 18 e 81 anos, em qualquer estágio clínico, em tratamento ou acompanhamento do câncer. Instrumentos: MOCS e Termômetro de desconforto emocional. Análises estatísticas: análise fatorial confirmatória para avaliar o ajuste do modelo aos dados por meio do método de máxima verossimilhança e pontos de corte. Resultados: Foram obtidos dois modelos, o primeiro estado atual autopercebido com um alfa de 0,90 variância explicada de 74,2 %, o segundo efeito inespecífico com um alfa de 0,61 variância explicada de 74,3 %; a análise fatorial confirmatória mostrou que ambos os modelos tiveram índices que sugerem estabilidade, ajuste aceitável e são demonstradas pontuações por meio de intervalos interquartis para cada modelo. Conclusões: a versão mexicana do MOCS tem confiabilidade e validade; sua estrutura fatorial confirmatória é semelhante à versão original. É recomendado para prática clínica e pesquisa em pacientes com câncer.
