Objective: To evaluate the effect of educational intervention in the adherence to self-care activities and functional health literacy and numeracy in people with type 2 diabetes mellitus. Methods: This was a quasi-experimental study conducted in two units of the Brazilian Family Health Strategy, involving people with diabetes. Educational interventions occurred in three meetings, weekly, lasting 60 minutes on average. Data were collected using the Questionário de Autocuidado com o Diabetes, before and after the interventions. Results: 55 people participated in the study. After the interventions, the greatest difference for a better adherence to self-care was the item “inspecting the inside of the shoes before putting them on”, with 3.29 days in the week delta at analytical level. The worst was “taking insulin shots as recommended”, with 0.00 days a week delta at basic level. Conclusion: Educational interventions had a positive effect on adherence to self-care and functional literacy in health.

Resumo Objetivo Avaliar os aplicativos móveis disponíveis sobre pré-eclâmpsia (PE) nos principais sistemas operacionais para a promoção da saúde de gestantes. Métodos Estudo avaliativo dos aplicativos móveis disponíveis nas plataformas (iOS e Android). Foi realizada uma busca sistemática nas lojas virtuais dos principais sistemas operacionais: Play Store (Android, Google ) e App Store (iOS, Apple ) de abril a junho de 2018, delimitando-se as seguintes etapas: estabelecimento dos objetivos da avaliação e dos critérios de inclusão e exclusão de aplicativos (seleção da amostra), definição das informações a serem extraídas, análise dos resultados, discussão e apresentação da avaliação. Para tanto, foram utilizados dois dispositivos: um Samsung Galaxy S8, compatível com Android e um Iphone 8, compatível com iOS versão 10.2.1. Três buscas foram realizadas em cada loja virtual, utilizando-se individualmente cada uma das seguintes palavras-chaves: Pré-eclâmpsia; eclâmpsia e promoção da saúde de gestantes com pré-eclâmpsia. Resultados 11 aplicativos foram elegíveis para o estudo. Todos estavam presentes no sistema operacional Android e apenas um estava disponível nos dois sistemas operacionais, Android e iOS. Dos 11, seis aplicativos abordavam características da pré-eclâmpsia; apenas um abordava o manejo clínico da PE. A avaliação do aplicativo variou de 14 a 29 pontos em um escore que varia de 6 a 30 pontos. Apenas dois aplicativos possuíam versões em português. Conclusão Foi possível verificar que os aplicativos possuem informações importantes que podem esclarecer eventuais dúvidas que as gestantes possam ter.

Objetivou-se identificar as melhores evidências sobre estratégias de educação em saúde utilizadas para ensino-aprendizagem de pessoas com diabetes mellitus e pé em risco neuropático. Revisão integrativa realizada nas bases de dados PubMed, LILACS, CINAHL e SCOPUS em janeiro de 2015, com uma amostra de 14 artigos analisados na íntegra. Nos resultados, as evidências foram apresentadas em quadro-síntese e discutidas em categorias, abrangendo as diferentes estratégias de educação em saúde para prevenção/manejo do pé em risco neuropático (grupal; individual nas consultas ou por telefone; e utilizando tecnologias interativas) e a síntese das melhores evidências da efetividade destas intervenções na redução de complicações do pé diabético. Concluiu-se que todas as estratégias educativas são efetivas na promoção do autocuidado do pé diabético. Porém, as estratégias grupais mostraram maior eficácia, possibilitando melhora significativa nos conhecimentos, atitudes e práticas do cuidado com os pés e com a saúde, em geral, de pacientes diabéticos.

Dimensioning the instrumentation: Exploratory or confi rmatory factor analysis?Re: Quality of nursing care: Instrument development and validation Dear Editor, Martinez et al. in their research entitled as "Quality of nursing care: Instrument development and validation", published in volume 69 and issue 5 in 2016, have done a valuable work in relation to the design and psychometry of instrument as well as the relevant areas (Nurses' perceptions of activities leading to increased quality of care by nurses) (1) . There are some tips in some parts of the research methodology that need to be considered. Explaining them seems to be capable of improving the work in future research and to be a guidance for other researchers in the field of design and validity of the instrument. Conceptualization and generating items in this study were performed with a deductive approach and by using OE -Ordem dos Enfermeiros (Order of Nurses) standard related to Portugal standards. Sampling in large sample size and focusing on the validity and reliability of the provided tool are as the strengths of the mentioned study.Papers appraisal is essential for the growth of knowledge and improves the quality of scientific research (2) . Scientific review of articles can be useful for readers and researchers regarding the increase of the article quality (3) . The mentioned study is criticized from two major aspects: In evaluating the newly designed instrument validity, only the qualitative content analysis (intelligibility, clarity and communication) has been mentioned. Although this evaluation is proper and accurate, but it is not enough, and CVI or CVR have not been calculated (4)(5) , while focusing on these indices is crucial in instrumentation and represents the issue that whether the instrument content fully assesses the studied structure or not (5) . The important, and in fact, the main thing to notice is that followed by sampling, the exploratory factor analysis method was used to assess the construct validity, while the dimensions have been specified in the beginning of the study and it is even determined that which items would be placed in which dimensions. In this context, the factor analysis of choice will be of confirmatory type and not the exploratory kind (5)(6)(7) . Since, the confirmatory type is the test hypothesis, suggesting that whether the statements included within each dimension are really fit and belong to that dimension or not (4) . The exploratory type, as the name implies, involves the detection and determining the dimensions. Sometimes, the texts can be used to state the dimensions of a structure. However, to specify which statements need to be placed in the made instrument, the exploratory factor analysis prediction should be employed in such circumstances.The purpose of the aforementioned is helping the illustration of key points in the design of the instrument and mentioning of some necessary points. Researchers would like to appreciate the Rev Bras Enferm Journal as it accepts the review of articles with contentm...
