ABSTRACT
Venous Ulcers (VU) are a serious health problem that affect the Quality of Life (QoL). They are evaluated by many different scales in the literature. We aimed to analyze the correlation between the Medical Outcomes Short-Form Health QoL (SF-36) and Charing Cross Venous Ulcer Questionnaire (CCVUQ) scales. This is a cross-sectional study conducted in a Brazilian center specializing in chronic VU of the Primary Health Care (PHC) provided to patients with active VU. The general QoL instrument SF-36 and the CCVUQ, specific for people with VU, were used. Spearman's Rho Test determined the correlation between the variables analyzed. Our sample had a total of 150 patients. We found a direct correlation between the domestic activities division (CCVUQ) aspect and the SF-36 Physical role functioning (strong), and Physical functioning (moderate) domains. The Social interaction division (CCVUQ) aspect presented moderate correlation with the domains of the SF-36 Physical role functioning and Physical functioning. The Vitality domain (SF-36) showed moderate correlation with the aspects of CCVUQ Cosmesis division and Emotional status division. The greatest forces of direct correlation were observed between the physical, functional and vitality aspects of SF-36 with those represented by domestic activities and social interaction in the CCVUQ.

ABSTRACT Objective: to present evidence of validity of an instrument aimed at evaluating the knowledge of nursing students about the care of the wounded patient, according to the difficulty and discrimination indexes of the items. Method: methodological study conducted in a nursing higher education institution with 117 undergraduate students and 38 professionals from a research group with experience in the area of wounds. For data collection, a questionnaire with 10 multiple choice questions was applied before and after classes on wounds. Results: most of the questions presented low level of difficulty and inefficient discrimination index, requiring a revision of the instrument. After two review stages, the difficulty and discrimination indexes of the instruments improved. Conclusion: an instrument with better evidence of validity was obtained. However, it still requires refinement for later revalidation in the same population.
RESUMEN Objetivo: identificar las evidencias de validez según los índices de dificultad y discriminación de los ítems de un instrumento con el fin de evaluar el conocimiento de académicos de enfermería en el cuidado de la persona lesionada. Método: se trata de un estudio metodológico desarrollado en una institución de enseñanza superior de enfermería realizado entre 117 estudiantes de graduación y 38 profesionales con experiencia en el área de heridas pertenecientes a un grupo de investigación. Se recogieron los datos mediante un cuestionario de 10 preguntas de opción múltiple, aplicado antes y después de las clases sobre heridas. Resultados: la mayoría de las cuestiones presentó un nivel bajo de dificultad y poder discriminativo ineficiente, haciéndose necesaria la revisión del instrumento. Tras dos etapas de revisión, el cuestionario demostró una mejoría de los índices de dificultad y discriminación. Conclusión: se logró un instrumento con mejor evidencia de validez, aunque tuvo que ser perfeccionado para su posterior revalidación en la misma población.
RESUMO Objetivo: Identificar as evidências de validade, segundo os índices de dificuldade e discriminação dos itens, de um instrumento para avaliação do conhecimento de acadêmicos de enfermagem no cuidado à pessoa com lesão. Método: Estudo metodológico desenvolvido em instituição de ensino superior de enfermagem com 117 estudantes de graduação e 38 profissionais componentes de grupo de pesquisa com experiência na área de feridas. Para coleta de dados, utilizou-se um questionário com 10 questões de múltipla escolha, aplicado antes e após as aulas de feridas. Resultados: A maioria das questões apresentou baixo nível de dificuldade e poder discriminativo ineficiente, sendo necessária a revisão do instrumento. Após duas etapas de revisão, o questionário apresentou melhora dos índices de dificuldade e discriminação. Conclusão: Obteve-se um instrumento com melhores evidências de validade, embora com necessidade de refinamento para posterior revalidação na mesma população.
