Propriedades psicométricas da Dutch Fatigue Scale e Dutch Exertion Fatigue Scale: versão brasileira

Abstract

Fatigue is a human response in varied acute and chronic conditions and also in general population. This article reports a study conducted to estimate reliability and validity of the Dutch Fatigue Scale (DUFS) and the Dutch Exertion Fatigue Scale (DEFS) adapted for Brazilian use. Three-hundred heart failure patients and 64 healthier volunteers answered the DUFS and DEFS translated into Portuguese. Factorial analysis of DUFS and DEFS items yield a solution with one factor for each scale (explained variance = 53.9%), and good reliability estimates were obtained by the Chronbach's alpha (DUFS=.85 e DEFS=.92). In the patient sample, scales scores were positively associated with heart failure functional class (DUFS and DEFS p=.00), depression scores (DUFS r s=.63; p=.00 and DEFS r s=.55; p=.00), and sleep disturbance (DUFS and DEFS p=.00). Brazilian versions of DUFS and DEFS presented psychometric properties similar to those of the original ones.

Correlation between clinical and socioeconomic characteristics and perceived health status of patients with heart failure

“…However, the number of studies that evaluate the relationship between the health statuses of HF patients with clinical indicators is still incipient especially in. Published studies do not associate generic and specific ESP, leaving gaps in relation to the behavior of these variables, as well as do not correlate with other data, such as clinical and socioeconomic CRUZ, 2009;CRUZ, 2013).…”

Características da fadiga no pré e pós-operatórios de cirurgia de revascularização do miocárdio

“…Fini e Cruz (2008) realizaram a validação e adaptação desses instrumentos para o uso no Brasil em pacientes com insuficiência cardíaca (IC) (35,36) .…”

“…A prevalência de fadiga em pacientes com cardiopatia é elevada (13,14,17,22,35,36,65) . Naqueles com IC a prevalência de fadiga pode variar de 47% a 83% (35,57,(65)(66)(67) .…”

“…Para avaliação da fadiga foi utilizada a Dutch Fatigue Scale -DUFS (Anexo 2) (27,36) . Esta escala foi desenvolvida e publicada por três holandeses em 1998 a fim de mensurar a intensidade da fadiga (27) .…”

“…Originalmente era composta de nove itens, porém, após estudo de adaptação transcultural e validação para o português falado no Brasil permaneceu com oito itens, com estimativa adequada de confiabilidade (alfa de Cronbach=0,848) (27,36) . (26,27,35,36) .…”
