Validation study of the Chinese version of the Brief Fatigue Inventory (BFI-C)

Abstract

A cross-sectional study was conducted among 249 Chinese cancer patients with multiple diagnoses to validate a Chinese version of the Brief Fatigue Inventory (BFI-C). Cronbach's coefficient alpha was 0.92 for fatigue severity items and 0.90 for fatigue interference items. Construct validity was explored by principal factor analysis and suggested a two-factor solution: fatigue severity and fatigue interference. Internal consistency reliability was excellent. Convergent validity was examined by correlating the BFI-C with 2 subscales and 2 component scores of the MOS 36-Item Short-Form Health Survey (coefficients ranged between -0.44 and -0.71, P<0.001). Known-group validity was examined by comparing fatigue severity in patients having different scores on the Eastern Cooperative Oncology Group Performance Status Scale. Approximately 60% of patients experienced moderate to severe fatigue (4 or greater on the 0-10 scale of the BFI-C "fatigue worst" item). The BFI-C is a valid, reliable instrument to measure the severity and impact of cancer-related fatigue among Chinese patients.

Assessment of Fatigue in Cancer Patients and Community Dwellers: Validation Study of the Filipino Version of the Brief Fatigue Inventory

“…The Brief Fatigue Inventory (BFI) was developed to assess the severity of cancer patients’ fatigue and how much fatigue interferes with daily activities [6]. The BFI’s validity and reliability have been confirmed in English and in other languages, including traditional and simplified Chinese, German, Greek, Japanese, Korean, and Russian [7,8,9,10,11,12,13]. However, a tool for measuring cancer-related fatigue has not been available for the Philippine cancer population.…”

“…We translated the BFI into Filipino using a standard translation/back-translation process, and we then assessed its psychometric properties in a sample of Filipino cancer patients and community-dwelling normal adults. This well-established procedure was followed in previous BFI language validation studies [7,8,9,11,12]. As a secondary goal, we used the BFI-F to document the prevalence and severity of fatigue in our Filipino study sample.…”

“…Los autores nombran esa dimensión como "severidad de fatiga" 3 . Mientras tanto, un estudio de validación del instrumento en una población de adultos mayores de la comunidad en Estados Unidos de Norteamérica 13 y otro estudio de validación del instrumento en pacientes con cáncer 15 identificó dos factores: severidad de la fatiga e interferencia. Es posible que la condición de hospitalizado haya interferido en el resultado de ese estudio.…”

“…Similares hallazgos han obtenido en pacientes con otros tipos de cáncer reportándose fatiga modera o severa en 48% 13,15 . Se observó que el ítem relativo al impacto que tenía la fatiga en la capacidad de disfrutar la vida obtuvo el mayor puntaje.…”

Reliability and Validity of Turkish Versions of the Child, Parent and Staff Cancer Fatigue Scales

“…One of such symptoms is fatigue defined by the National Comprehensive Cancer Network as "a distressing persistent, subjective sense of physical, emotional and/ or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning" (Mock, 2000). As a cancer related symptom, fatigue has often been focused in a number of studies from a variety of perspectives and several scales have been consequently developed to identify the symptom in detail and adapted into different languages (Cleeland et al, 2000;Radbruch et al, 2003;Wang et al, 2004;Lin et al, 2006;Shun et al, 2006;Wu et al, 2006). Neverthless, it is worth noting that the studies on fatigue in pediatric populations still remain insufficient and based on one group (Hinds et al, 1999a(Hinds et al, : 1999bHinds and Hockenberry, 2001;Hockenberry et al, 1998Hockenberry et al, : 1999.…”
