Abstract
This study was ubdertaken to investigate the content validity of an instrument about knowledge on nasogastric intubation, based on the Pasquali model of content validation. Methods: methodological study developped with 23 nurses judges, teachers from public higher education institutions in the state of Rio Grande do Norte, by the application of Content Validity Index (CVI) and the Kappa index. The majority of the research judges were female (87%), age between 25 and 57 years-old, teaching time experience between 1 and 34 years and experience in the discipline of Nursing Semiology and/or Semiotics between 1 and 32 years. Of the total judges, 78.3% had master's degree as the maximum degree and 69.6% exercised exclusively the teaching. In the overall evaluation, the instrument obtained CVI values above 0.75, 0.94 the total CVI and 0.88 the total Kappa. However, some changes were made and focused on the requirements: vocabulary, clarity, updating and accuracy. The instrument showed reliability and trustworthy to observe the nursing care quality, however requires the resubmission of instruments to the same judges to retest, beyond its clinical application, for a more precise and specific content validation.
Highlights
The knowledge constitutes an essential tool for the nursing practice
The guidelines for the nasogastric tube insertion and assistance to patients who use it must be guiding on scientific basis in order to result in a secure action to the patient with a view to the need to prevent risks related to nursing actions (HERMANN; CRUZ, 2008; CERIBELLI; MALTA, 2006)
The teachers selected for content validation were a total of 23 judges, mostly female (87%), aged between 25 and 57 years-old, time variation of teaching experience between 01 and 34 years and experience in the Semiology and/or Semiotechnique Nursing discipline between 01 and 32 years
Summary
Many studies show the gap between the knowledge referred by nurses and the patient care in general, as well as those with nasogastric tube (MOREIRA; BERNARDINO JÚNIOR, 2013; CHAN et al, 2012; METHENY; STEWART; MILLS, 2012; HERMANN; CRUZ, 2008). In this context, the guidelines for the nasogastric tube insertion and assistance to patients who use it must be guiding on scientific basis in order to result in a secure action to the patient with a view to the need to prevent risks related to nursing actions (HERMANN; CRUZ, 2008; CERIBELLI; MALTA, 2006). That process have two stages, the first is the development of the instrument and the second involves the analysis and judgment of specialists (POLIT; BECK, 2006)
