Resumo
Fatigue is a subjective phenomenon, characterized by a feeling of
tiredness, being one of the most frequent symptoms in the postoperative period.
Internationally, there is the scale Identity- Consequences Fatigue Scale (ICFS),
multidimensional, specific to this population, composed of 29 items and five
subscales. In Brazil, research on the consequences of the impact of fatigue on the
lives of patients undergoing surgery are scarce. Moreover, their fatigue evaluation is
difficult to perform, we suggest the analysis of this phenomenon by means of specific
instruments and surgical population scales. Thus the cross-cultural adaptation and
validation of specific assessment tools that phenomenon being, are necessary.
PURPOSE. Perform cross-cultural adaptation to Brazilian Portuguese and validate
the ICFS for fatigue assessment in surgical patients. METHODOLOGY.
Methodological study of cross-cultural adaptation and validation of an assessment
tool for postoperative fatigue, ICFS, linked to a scientific Project - multicenter
technological "Fatigue in cancer patients: exploring the symptom in surgical patients
and advancing in clinical patient care," approved by the Federal University of Goiás
Research Ethics Committee and by the Association of Cancer Combat of Goiás
Research Ethics Committee. The method is described in two stages: the first refers to
the cross-cultural adaptation and the second for testing the psychometric properties.
RESULTS. The ICFS was translated independently by two bilingual Brazilians,
finding 31 items with disagreement among translators. After the consensus version
was held back-translation by a bilingual native North American translator. This
version was sent to the lead author of the instrument considering similar to the
original version. Following the panel of judges evaluated and suggested
modifications in sixteen items and followed. Finally, the pretest was in surgical
patients, they considered to be the instrument understandable. Thus Obtained the
Brazilian version of the Scale Identification and Consequences of Fatigue (EICF). In
the validation phase EICF was applied 99 (ninety-nine) participants (n = 99, 61.6%
postoperative), concomitantly the Piper Fatigue Scale-Revised (PIPER) and Hospital
Anxiety and Depression Scale (HADS). The analysis included assessing the internal
consistency, convergent validity, concurrent and construct. The KMO test considered
the minimum sample size. Identified the Identification of Fatigue scale with two
subscales, and the Consequences of Fatigue scale with three subscales. Internal
consistency for the subscales was very good (Cronbach α> 0.775). The scores of
EICF positively correlated with the scores of the HADS scales and Piper. The
Brazilian version EICF- showed - is valid for surgical patients and clinical treatment.
We conclude that the Brazilian version of EICF is valid and reliable. FINAL. Obtained
the end Scale Identification and Consequences of Fatigue - Brazilian version,
culturally sensitive, valid and reliable, consisting of 29 items arranged in two
dimensions and five subscales. A new tool for assessing fatigue surgical patients
during the postoperative period will enable the improvement of the health care
professional in this target population.
