Construction and validation of indicators and respective definitions for the nursing outcome Swallowing Status

Abstract

OBJECTIVE: to develop indicators for the nursing outcome Swallowing Status and the respective conceptual and operational definitions validated by experts and in a clinical setting among patients after having experienced a stroke. METHOD: methodological study with concept analysis and content and clinical validations. The Content Validation Index was verified for the scores assigned by 11 experts to indicators. Two pairs of nurses assessed 81 patients during the clinical validation: one pair used an instrument with definitions and the other used an instrument without definitions. The resulting assessments were compared using Intraclass Correlation Coefficient, Friedman's test, and Minimal Important Difference calculation. RESULTS: All the indicators, with the exception of the indicator Ability to bring food to mouth, presented Content Validation Index above 0.80. The pair using the instrument with definitions presented an Intraclass Correlation Coefficient above 0.80 for all the indicators and similarity was found in all the assessments, according to the Minimal Important Difference calculation. The pair using the instrument without definitions presented a low coefficient (ρ<0.75) for all the indicators. CONCLUSION: the results showed that greater uniformity and accuracy was achieved by the pair of nurses using the conceptual and operational definitions for the indicators of the nursing outcome Swallowing Status.

Psychometric Assessment of the Nursing Outcome Swallowing Status: Rasch Model Approach

“…In this study, results confirmed the unidimensionality of Swallowing status outcome. Previous methodological study with concept analysis and content and clinical validations contributed to refine this outcome (Oliveira et al., ).…”

“…A nurse provided a score using a value ranging from 1 (worst result) to 5 (best health status). Operational definitions were previously developed for each indicator to allow a more accurate result analysis performed by the nurse (Oliveira et al., ).…”

“…For instance, Oliveira et al. () studied the outcome named as “Swallowing status.” In their first study, objectives included developing and performing expert and clinical validation of indicators for this nursing outcome and its conceptual and operational definitions among patients after a stroke. Their second study aimed to clinically validate this nursing outcome, testing whether swallowing scale measures swallowing ability in a group of stroke patients and also verifying its reliability and consistency across different populations, according to the classical test theory (CTT) and item response theory (IRT).…”

“…This nursing outcome was submitted to expert and clinical validation. Its conceptual and operational definitions were assessed by poststroke patients in a previous study (Oliveira et al., ).…”

Clinical indicators of dry eye severity nursing outcome in intensive care unit

“…The NOC presents advantages such as reduced documentation time, better patient satisfaction and results, greater uniformity in the evaluation of the professional nurse and improved quality of care ( 9 - 10 ) . This study is justified by the importance of developing a clinical evaluation focused on the condition of eye health and prevention of adverse events to the patient, using a taxonomy composed of a set of indicators to direct the care and determine interventions that provide positive results.…”
