“…The scale has been tested for construct validity, internal consistency, and criterion-related validity in cardiac patients in a Dutch [12] and a Lithuanian sample. [24] Prevalence of fatigue General fatigue and mobility-related fatigue are relatively prevalent in the general older population. A Danish study based on data from the 1914-cohort from the Glostrup Aging Studies showed that the proportion of men and women with mobility-related fatigue increased with age from age 70 to age 85.…”

The aim of this paper is to give an overview of research on general fatigue, mobility-related fatigue, and fatigability in older adults, with a focus on fatigue as an early indicator of the aging process. Fatigue is a strong predictor of functional limitations, disability, mortality, and other adverse outcomes in young-old and old-old populations, in men and women, and in different geographic localities. Several biological, physiological, and social explanations are proposed: fatigue may be seen not only as a self-reported indicator of frailty, defined as a physiologic state of increased vulnerability to stressors which results from decreased physiologic reserves and even dysregulation of multiple physiologic systems, but this state may be accelerated by the cumulative impact of social, mental, and biological factors throughout life. Fatigue in older adults is the result of multiple potentially modifiable factors, of which some may be fully treated or at least alleviated, thus slowing down the speed of the aging process.

“…Exertion fatigue, defined as fatigue directly related to the performance of daily activities in the spheres of household, personal hygiene, and social life, was evaluated using the self-report Dutch Exertion Fatigue Scale (DEFS) (28). The DEFS consists of nine items that are rated on a 5-point Likert scale ranging from 0 to 4.…”

“…The time frame is the last few days. MFI scales have shown good psychometric properties across several chronic diseases and languages [34,35,36] and good internal consistency (Cronbach's α across scales ranging from 0.80 to 0.94). In the current study, Cronbach's α yielded 0.72-0.84, which were all above what is minimally acceptable given the scale length and the average inter-item correlation [37,38,39,40,41].…”

Influence of Disease Severity on Fatigue in Patients with Parkinson's Disease Is Mainly Mediated by Symptoms of Depression

Purpose: Fatigue is a frequent non-motor complaint of patients with Parkinson's disease (PD). Despite increasing knowledge on fatigue, the factors leading to its development are still not recognised. The aim of this investigation was to test, using structural equation modelling, the hypothesis that the influence of disease severity on fatigue is mediated by symptoms of depression in patients with PD. Method: The sample consisted of 190 PD patients (93 men, 48.9%, mean age 68.2 ± 9.3 years, mean disease duration 6.4 ± 4.7 years) recruited from hospitals and outpatient clinics in the East Slovakia region. The Multidimensional Fatigue Inventory, the Hospital Anxiety and Depression Scale and the Unified Parkinson's Disease Rating Scale were used. LISREL was used to analyse the data. Results: Disease severity was directly associated with symptoms of depression (β = 0.26) and directly affected fatigue in terms of increased levels of general fatigue (β = 0.35), physical fatigue (β = 0.22), reduced activity (β = 0.31) and mental fatigue (β = 0.29), but did not directly influence reduced motivation. Symptoms of depression mediated the impact of disease severity on general fatigue (β = 0.25), on reduced activity (β = 0.31) and on mental fatigue (β = 0.28), but not on physical fatigue. Reduced motivation was not mediated, but directly influenced by more symptoms of depression (β = 0.82). Discussion: Since increased symptoms of depression mediate the impact of disease severity on three domains of fatigue in PD patients, disease management should focus on the treatment of PD and symptoms of depression.

Construct and criterion validity of the DUFS and DEFS4 in Lithuanian patients with coronary artery disease

Abstract: The construct validity and criterion validity of the DUFS and DEFS were confirmed in a Lithuanian sample of cardiac patients. The construct validity of the MFI was also supported and this fatigue measure can be used in Lithuanian settings of clinical practice and research.
