“…remained constant at the two moments evaluated (test and retest). These results were similar to those for Valderramas et al (26) . This study also found a strong correlation of fatigue with depressive symptomatology and quality of life, demonstrating that the more severe the fatigue, the more severe the depressive symptomatology and the greater impairment of quality of life.…”

“…The sample size calculation was based on the studies of Valderramas et al (26) and Mendes et al (17,18) , amounting to a minimum of 87 patients and a minimum sample size calculation for each psychometric property studied: internal consistency and construct validity n=87; Reproducibility n=23; Validity of criterion n=23; Discriminant validity n=21; Responsiveness criterion n=15. Each psychometric property studied was a subgroup extracted from the total sample.…”

“…The higher the score, the greater the severity of the symptom (17) . It was tested in (26) different populations (7,11,13) , demonstrating good psychometric properties, but has not yet been tested in Brazilian cirrhotic patients. It has been translated and adapted to Brazilian Portuguese by Mendes et al (17,18) .…”

-Background -Fatigue is a common complaint in cirrhotic patients and may be considered a debilitating symptom with negative impact on quality of life. Research on its etiology and treatment has been hampered by the lack of relevant and reproducible measures of fatigue. Objective -To evaluate the psychometric properties of the Fatigue Severity Scale (FSS) in cirrhotic patients and to correlate with depressive symptomatology and quality of life. Methods -Cross-sectional study with a convenience sample of 106 cirrhotic patients, aged between 18 and 70 years, both genders, literate, pre and post liver transplantation in outpatient follow-up. Internal consistency, reproducibility, discriminant validity, criterion validity, construct validity, responsiveness criterion, depressive symptomatology and quality of life were evaluated through questionnaires between January and October 2015. Results -The mean age was 54.75±9.9 years, 65.1% male and 32.1% of the sample had cirrhosis due to hepatitis C virus. The mean FSS score was 4.74±1.64. Cronbach's alpha was 0.93, and the Intraclass Correlation Coefficient was 0.905 (95% CI: 0.813-0.952). For discriminant validity, FSS differentiated scores from different groups (P=0.009) and presented a correlation with the Modified Fatigue Impact Scale (r=0.606, P=0.002). FSS correlated significantly and positively with depressive symptomatology and correlated negatively with the SF-36 domains for construct validity. For responsiveness, no significant changes were observed in the fatigue scores in the pre and post-liver transplantation periods (P=0.327). Conclusion -FSS showed good psychometric performance in the evaluation of fatigue in patients with cirrhosis. Fatigue presented a strong correlation with depressive symptomatology and quality of life.

“…In the present study, we used the Portuguese-language version of the FSS validated for use in Brazil. (23) Symptoms of depression and anxiety states were assessed using the Hospital Anxiety and Depression Scale (HADS). This scale consists of 14 items, of which 7 focus on the assessment of anxiety (HADS-A subscale), and 7 focus on the assessment of depression (HADS-D subscale).…”

Objective: To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. Methods: This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who completed the ICFS. Patients with chronic heart disease (CHD) and healthy controls, matched for age and gender, also completed the scale. Initially, a Brazilian Portuguese-language version of the ICFS was administered to 50 LC patients by two independent interviewers; to test for reproducibility, it was readministered to those same patients. At baseline, the LC patients were submitted to spirometry and the six-minute walk test, as well as completing the Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), and Fatigue Severity Scale (FSS). Inflammatory status was assessed by blood C-reactive protein (CRP) levels. To validate the ICFS, we assessed the correlations of its scores with those variables. Results: The sample comprised 50 patients in each group (LC, CHD, and control). In the LC group, the intraclass correlation coefficients for intra-rater and inter-rater reliability regarding ICFS summary variables ranged from 0.94 to 0.76 and from 0.94 to 0.79, respectively. The ICFS presented excellent internal consistency, and Bland-Altman plots showed good test-retest reliability. The ICFS correlated significantly with FSS, HADS, and SF-36 scores, as well as with CRP levels. Mean ICFS scores in the LC group differed significantly from those in the CHD and control groups. Conclusions: The ICFS is a valid, reliable instrument for evaluating LC patients, in whom depression, quality of life, and CRP levels seem to be significantly associated with fatigue.

Introduction: Individuals after stroke present several motor impairments, which reduced the functional capacity. The understanding of modifiable factors which are related to functional capacity in individuals with chronic stroke could better direct clinical practice. However, the mechanisms that could influence functional capacity in individuals with chronic stroke are not fully understood.Objective: This study aimed to determine which modifiable variables would best predict self-reported functional capacity after stroke.
