Brazilian-Portuguese Validation Assessment of the Gastrointestinal Quality of Life Index for Patients After Laparoendoscopic Cholecystectomy

Background: Cholelithiasis is currently one of the most common diagnosis in Brazil. The aim of this study was to validate the Gastrointestinal Quality of Life Index (GIQLI) as a quality-of-life (QoL) assessment among the Brazilian population with syntomatic gallstone. Materials and Methods: The questionnaire was translated and culturally adapted after the linguistic validation process determined by the international methodology. Sixty-three patients who underwent laparoscopic cholecystectomy responded to the GIQLI-Brazil and Short-Form Health Survey (SF-36) instruments. For the evaluation of reproducibility, 30 patients responded to GIQLI-Brazil two more times after 2 and 4 weeks. After the University of São Paulo Ethics Commitee Board approval (UNIFESP/CEP: 1270/2019), the study was carryed out between May 2019 and February 2020 at the Gastroenterology outpatient clinic of Hospital São Paulo-Federal University of São Paulo (UNIFESP). Cronbach's alpha, the calculation of the intraclass correlation coefficient (ICC), and Spearman's correlation were used to assess the validity and reproducibility of the instrument translated into Portuguese, and to measure correlation between the domains of the GIQLI-Brazil and SF-36 (P < .05). Results: Seven questions were modified during the process of translation and cultural adaptation. The Brazilian version of the instrument presented a Cronbach's alpha of 0.89, and excellent reproducibility through the ICC, with the following variation between domains: meteorism (ICC = 0.918; P < .001) and gastrointestinal function (lower tract) (ICC = 0.956; P < .001). The dimensions of the GIQLI-Brazil and SF-36 demonstrated a significant correlation (P < .001), except between the domains: functional aspects of the SF-36 and gastrointestinal function (lower tract) of the GIQLI-Brazil (r = 0.211). Conclusion: The GIQLI was translated and validated for Portuguese-Brazil and can be used to assess the QoL of adult patients with gastrointestinal diseases and/or disorders.

Cross-cultural adaptation and content validation into Portuguese of the Subjective Global Nutritional Assessment for pediatric patients hospitalized with cancer

ABSTRACT Objective Cross-cultural adaptation and content validation of the Brazilian Portuguese version of the Subjective Global Nutritional Assessment questionnaire (originally in English) for use in hospitalized children and adolescents being treated in a reference institute of oncology. Methods The cross-cultural adaptation process consisted of the following stages: conceptual, item, semantic, and operational equivalence. The conceptual equivalence and item was carried out through discussion with members of an expert committee. Semantic equivalence was evaluated through initial translation, synthesis of translations, back translation, discussions with experts, and pretest with 32 patients. During operational equivalence, the experts discussed about the format of questions and instructions, setting, target populations, and mode of administration to later propose a final version. Content validation was performed by the expert committee. Results Minor modifications were made in the instrument to facilitate its use in the Brazilian socio-cultural context. Pretest results showed that the instrument is easily understood by health care professionals and the target population. Conclusion The cross-cultural adaptation and validation of the Subjective Global Nutritional Assessment allowed obtaining a Brazilian version equivalent to the original. The adapted instrument will be an important tool for the subjective assessment of the nutritional status of pediatric patients hospitalized with cancer.

Equivalência semântica do Questionário Pediatric Subjective Global Nutritional Assessment para triagem nutricional em pacientes pediátricos com câncer

Objetivo: Realizar a equivalência semântica da Avaliação Nutricional Subjetiva Global Pediátrica e sua adaptação para a língua portuguesa para aplicação em pacientes pediátricos hospitalizados com câncer. Métodos: O processo de equivalência semântica envolveu as seguintes etapas: tradução, síntese das traduções, retrotradução, discussão com comitê de especialistas e pré-teste, etapas que aconteceram na Universidade Federal do Rio de Janeiro e no Instituto Nacional de Câncer José Alencar Gomes da Silva. O questionário foi pré-testado em 32 pacientes pediátricos com câncer, de 2 a 18 anos, para verificar sua adequação nessa população. Resultados: Todas as etapas fundamentaram a equivalência semântica do instrumento. Foram necessárias discretas alterações no instrumento Avaliação Nutricional Subjetiva Global Pediátrica para o contexto brasileiro. Na avaliação das 56 assertivas traduzidas para o português, 81% das respostas dos especialistas classificaram como "inalterado" o significado geral. Evidenciou-se uma boa equivalência semântica entre a tradução e a retrotradução e a versão original. Conclusão: A versão brasileira da Avaliação Nutricional Subjetiva Global Pediátrica foi bem compreendida pela população do estudo e mostrou-se adequada para seguir com as demais etapas de adaptação transcultural e validação da ferramenta para posterior aplicação na população pediátrica hospitalizada com câncer.

Cross-cultural adaptation and psychometric properties of the Brazilian-Portuguese version of the VSP-A (Vécu et Santé Perçue de l'Adolescent), a health-related quality of life (HRQoL) instrument for adolescents, in a healthy Brazilian population

Background

Health-related quality of life (HRQoL) assessment, encompassing the adolescents' perceptions of their mental, physical, and social health and well-being is increasingly considered an important outcome to be used to identify population health needs and to provide targeted medical care. Although validated instruments are essential for accurately assessing HRQoL outcomes, there are few cross-culturally adapted tools for use in Brazil, and none designed exclusively for use among adolescents. The Vécu et Santé Perçue de l'Adolescent (VSP-A) is a generic, multidimensional self-reported instrument originally developed and validated in France that evaluates HRQoL of ill and healthy adolescents.

Purpose

To cross-culturally adapt and validate the Brazilian-Portuguese version of the VSP-A, a generic HRQoL measure for adolescents originally developed in France.

Methods

The VSP-A was translated following a well-validated forward-backward process leading to the Brazilian version. The psychometric evaluation was conducted in a sample of 446 adolescents (14-18 years) attending 2 public high schools of São Gonçalo City. The adolescents self-reported the Brazilian VSP-A, the validated Psychosomatic Symptom Checklist and socio-demographic information. A retest evaluation was carried out on a sub-sample (n = 195) at a two-week interval.

The internal construct validity was assessed through confirmatory factor analysis (CFA), multi-trait scaling analyses, Rasch analysis evaluating unidimensionality of each scale and Cronbach's alpha coefficients. The reproducibility was evaluated by intra-class correlation coefficients (ICC). Zumbo's ordinal logistic regression analysis was used to detect differential item functioning (DIF) between the Brazilian and the French items. External construct validity was investigated testing expected differences between groups using one-way analysis of variance (ANOVA), Mann-Whitney tests and the univariate general regression linear model.

Results

CFA showed an acceptable fit (RMSEA=0.05; CFI=0.93); 94% of scaling success was found for item-internal consistency and 98% for item discriminant validity. The items showed good fit to the Rasch model except 3 items with an INFIT at the upper threshold. Cronbach's Alpha ranged from 0.60 to 0.85. Test-retest reliability was moderate to good (ICC=0.55-0.82). DIF was evidenced in 4 out of 36 items. Expected patterns of differences were confirmed with significantly lower physical, psychological well being and vitality reported by symptomatic adolescents.

Conclusions

Although DIF in few items and responsiveness must be further explored, the Brazilian version of VSP-A demonstrated an acceptable validity and reliability in adolescents attending school and might serve as a starting point for more specific clinical investigations.
