Department of Postgraduate Nursing Studies, University of Otago, Christchurch, New Zealand.Journal of pain and symptom management (Impact Factor: 2.8). 02/2009; 37(1):107-28. DOI: 10.1016/j.jpainsymman.2007.08.019
Fatigue is a common symptom associated with a wide range of chronic diseases. A large number of instruments have been developed to measure fatigue. An assessment regarding the reliability, validity, and utility of fatigue measures is time-consuming for the clinician and researcher, and few reviews exist on which to draw such information. The aim of this article is to present a critical review of fatigue measures, the populations in which the scales have been used, and the extent to which the psychometric properties of each instrument have been evaluated to provide clinicians and researchers with information on which to base decisions. Seven databases were searched for all articles that measured fatigue and offered an insight into the psychometric properties of the scales used over the period 1980-2007. Criteria for judging the "ideal" measure were developed to encompass scale usability, clinical/research utility, and the robustness of psychometric properties. Twenty-two fatigue measures met the inclusion criteria and were evaluated. A further 17 measures met some of the criteria, but have not been tested beyond initial development, and are reviewed briefly at the end of the article. The review did not identify any instrument that met all the criteria of an ideal instrument. However, a small number of short instruments demonstrated good psychometric properties (Fatigue Severity Scale [FSS], Fatigue Impact Scale [FIS], and Brief Fatigue Inventory [BFI]), and three comprehensive instruments demonstrated the same (Fatigue Symptom Inventory [FSI], Multidimensional Assessment of Fatigue [MAF], and Multidimensional Fatigue Symptom Inventory [MFSI]). Only four measures (BFI, FSS, FSI, and MAF) demonstrated the ability to detect change over time. The clinician and researcher also should consider the populations in which the scale has been used previously to assess its validity with their own patient group, and assess the content of a scale to ensure that the key qualitative aspects of fatigue of the population of interest are covered.

- "Fatigue was assessed with the " Fatigue Severity Scale " (FSS). FFS is a nine-item questionnaire developed to measure the impact of fatigue on daily functioning [Krupp et al., 1989; Whitehead, 2009], each item scored on a seven-point Likert scale. To assess the prevalence of " severe fatigue " versus " no fatigue " the following cut-off values were used; non-fatigue ¼ FFS mean score 4 and severe fatigue ¼ FFS mean score ! 5 [Roelcke et al., 1997; Lerdal et al., 2005].

ABSTRACT: Marfan syndrome (MFS) is a severe autosomal dominant connective tissue disorder that might influence peoples work ability. This cross sectional study aims to investigate work participation in adults with verified MFS diagnosis and to explore how the health related consequences of MFS and other factors might influence work participation. The prevalence of health problems in young adults compared to older adults with MFS was examined in association to work participation. A postal questionnaire including questions about work participation, demographic characteristics, MFS related health problems, chronic pain, and fatigue was sent to 117 adults with verified MFS (Ghent 1), and 62% answered. Fifty-nine percent were employed or students, significantly lower work participation than the General Norwegian Population (GNP), but higher than the Norwegian population of people with disability. Most young adults worked full-time despite extensive health problems, but the average age for leaving work was low. Few had received any work adaptations prior to retiring from work. In multiple logistic regression analysis, only age, lower educational level and severe fatigue were significantly associated with low work participation; not MFS related health problems or chronic pain. Fatigue appears to be the most challenging health problem to deal with in work, but the covariance is complex. Focus on vocational guidance early in life, more appropriate work adaptations, and psychosocial support might improve the possibility for sustaining in work for adults with MFS. More research about work challenges in adults with MFS is needed. © 2015 Wiley Periodicals, Inc.American Journal of Medical Genetics Part A 09/2015; DOI:10.1002/ajmg.a.37370 · 2.16 Impact Factor

- "The scales may be multidimensional (e.g., physical, emotional, and cognitive), unidimensional (e.g., sleep/rest), or a separate module within a larger health-related life quality instrument. Many scales assess the feelings of fatigue and the perceived effect of fatigue on life quality (for reviews see Dittner et al. 2004; Hjollund et al. 2007; Whitehead 2009). Although numerous fatigue scales exist for the adult population , there are very few, well-standardized instruments for children and adolescents (Hockenberry et al. 2003). "

- "This is a nine-item questionnaire developed to measure the impact of fatigue on daily functioning [Krupp et al., 1989]. The FSS is widely used and has been found valid and reliable in different patient groups [Whitehead, 2009]. Each item is scored on a seven-point Likert scale with a range from 1 (completely disagree) to 7 (completely agree). "
ABSTRACT: This study aims to investigate how fatigue affects adults with verified Marfan syndrome (MFS) in their daily lives, by examining fatigue levels and prevalence of severe fatigue compared to the general Norwegian population and individuals with other comparable chronic conditions. We investigated associations between socio-demographic characteristics, Marfan-related health problems, pain and fatigue. A cross-sectional study was conducted, using a postal questionnaire including the Fatigue Severity Scale (FSS) and questions on socio-demographic characteristics, Marfan-related health problems and pain. One hundred seventeen persons with MFS were invited to participate, 73 answered (62%). Participants reported significantly higher FSS scores and prevalence of severe fatigue compared to the general Norwegian population and patients with rheumatoid arthritis (RA), but lower than for other chronic conditions. Participants with chronic pain reported higher fatigue scores than those without chronic pain. Participants on disability benefits reported higher fatigue scores than participants who were working or enrolled in higher education. Marfan-related health problems like aortic dissection and use of blood pressure medication were not significantly associated with fatigue. In multivariable regression analyses chronic pain and employment status were significantly associated with fatigue. The final multivariable model explained 24% of the variance in fatigue scores. Our results show that fatigue is common in MFS patients and that it interferes with their daily lives. Chronic pain and employment status show significant associations to fatigue. This implies that fatigue is important to address when meeting MFS patients in clinical practice. There is need for more research on fatigue in Marfan syndrome. © 2014 Wiley Periodicals, Inc.American Journal of Medical Genetics Part A 08/2014; 164A(8).
