Abstract

ABSTRACT Objective The objective of this study was to translate and cross-culturally adapt the NutriQoL® into Brazilian Portuguese. Methods The NutriQoL® comprises 17 questions that evaluate the quality of life of patients receiving home enteral nutrition therapy. The methodological procedures included the translation from the Spanish version into Portuguese by two translators, synthesis of the translations, back translation, evaluation by a committee of judges composed of 24 individuals in which a content validity index > 0.78 was considered acceptable, and generation of the pre-final version. A pre-test to analyze its semantic equivalence was administered to 12 patients receiving home enteral nutrition therapy. The final version of the questionnaire was then prepared. Results A summary version of the questionnaire was obtained using two versions of the translation. Both back translations were identical for 73.6% of sentences (n=25). Twenty-four volunteers were included in the committee of judges. The content validity index was 0.88±0.11, and 14.7% (n=5) of questions had a low content validity index and were thus reformulated. In the pre-test, 35.3% (n=12) of items obtained low levels of understanding and required adjustment. In the preparation of the final version, the inconsistencies of the items mentioned were corrected and/or adjusted. Conclusion After completing the methodological procedures, a Brazilian Portuguese version of the NutriQoL® questionnaire was obtained. Following the validation process, it can be used by dieticians and other health professionals to assess the quality of life of patients receiving home enteral nutrition therapy to contribute to improvements in care practices.

Home Enteral Nutrition Therapy (HENT) is a form of nutritional care provided at home, with the objective of recovering or maintaining nutritional status [1]
Assessments of quality of life in patients who receive HENT are usually difficult to obtain and interpret because the questionnaires used for evaluations in these individuals are non-specific [8]

Summary

Introduction

Home Enteral Nutrition Therapy (HENT) is a form of nutritional care provided at home, with the objective of recovering or maintaining nutritional status [1]. As with enteral nutritional therapy in the hospital setting, HENT is not risk-free and may have physical effects on patients because of mechanical problems in the probe, such as leakage, displacement, and occlusion, and due to the formation of granular tissue at the insertion site, making the individual more susceptible to infections [1,2]. Other recurrent problems include gastrointestinal problems, mainly constipation, diarrhea, nausea, and vomiting, as well as metabolic complications, such as dehydration and body weight adjustment [2]. There may be psychological complications, as the patient’s transition from hospital to home can be stressful, confusing, and oppressive [4]
