The Chalder fatigue scale is widely used to measure physical and mental fatigue in chronic fatigue syndrome patients, but the constructs of the scale have not. Previous validation studies of the Chalder Fatigue Scale (CFS) suffer methodological shortcomings. The present study aimed to re-evaluate its.

Ngand S. The CFS was originally perceived as comprising two subscales that fatigie fatigue in the physical and mental domains. The Fatigue Scale, sometimes referred to as the Chalder Fatigue Scale the CFQ—to differentiate it from chronic fatigue syndrome or CFSis a self-administered questionnaire for measuring the extent and severity of fatigue within both clinical and non-clinical, epidemiological populations.

The authors have no competing interests to report. Factor 2 was correlated with difficulties in maintaining sleep. Model estimations were carried out using the robust maximum likelihood estimator. Open in a separate window. HoEric T. ChanRainbow T. Outcome Physical fatigue Low energy Mental fatigue Anxiety. The present study aimed to re-evaluate its psychometric properties using exploratory structural equation modeling ESEM.

Exploring the validity of the Chalder Fatigue scale in chronic fatigue syndrome.

Exploratory structural equation modeling. Conclusion The results demonstrate the satisfactory reliability and convergent validity for the three-factor structure of the CFS as a valid measure of fatigue symptoms in the general population. Related articles in Web of Science Google Scholar.

The unrealistic orthogonal factors resulting from varimax rotation likely lead to distorted factor structures [ 12 ]. Measuring fatigue in haemodialysis patients: Hard to concentrate 1. Cella M, Chalder T. FongJessie S. From Body to Mind and Spirit: The ESEM models used oblique geomin rotation [ 25 ] and identified exploratory factors by estimating the factor loadings on all factors within a structural equation modeling framework [ 1516 ].

About half had completed tertiary education Quality of Life Research. However, unlike CFA, exploratory factor analysis does not accommodate the use of model covariates or residual correlations. The ESEM solutions resulted in reduced interfactor correlations, suggesting that ESEM factors are more distinct and less susceptible to multicollinearity problems. The CFQ 11 has been used widely in studies ascertaining tiredness among working populations as well as patient groups and consistently fares extremely well against other longer and multidimensional fatifue [ 6 ].

Methods A Chinese sample of community-dwelling residents completed the item Chinese CFS and a variety of health measures anxiety, depression, exhaustion, sleep disturbance, and quality of life. Construct validity of the Chinese version of the Chalder Fatigue Scale in a Chinese community sample.

Effects of cognitive loading and force on upper trapezius fatigue. Such research could in turn enable early intervention to alleviate the fatigue symptoms of these individuals. Model fatigie was performed based on modification index with reference to standardized expected parameter change [ 26 ].

Another advantage is that the CFQ 11 is used widely in occupational research and allows for straightforward comparisons between studies and populations. From This Paper Figures, tables, sacle topics from this paper.

Showing of 4 extracted citations. Exploratory structural equation modeling of personality data. In contrast to the original two-factor structure [ 4 ], our results support a three-factor structure consisting of physical fatigue, scael energy, and mental fatigue. Five variables, namely gender, age, exercise, perceived health, and life event, were added to the ESEM model as model covariates.

Confirmatory factor analysis and reliability of the Chinese version of the Maslach Burnout Inventory among guidance teachers in Hong Kong.

Chronic fatigue is a symptom commonly reported by patients in primary care practice and by the general population, with prevalence of Cross-cultural validation of the Chalder Fatigue Questionnaire in Brazilian primary care. The Likert scoring system allows for means and distributions to be calculated for both the global total as well as the two sub-scales.

Exploring the validity of the Chalder Fatigue scale in chronic fatigue syndrome.

Similarly, a poor self-perception of health and recent experience of a major life event were significantly associated with greater mental fatigue. Future psychometric studies could adopt the ESEM approach as a practical alternative to traditional confirmatory factor analysis.

Model fit was evaluated via the criteria of the following goodness-of-fit indices [ 27 ]: American Journal of Psychiatry. Fong Sleep medicine For the four-factor ESEM model, the fourth factor had only one practically significant loading on the items, thus exhibiting little incremental value over the three-factor model.

Although they claimed to successfully replicate the original two-factor structure by showing a superior model fit for the latter model, the second-order factor model with only two first-order factors was actually statistically unidentified and addition of a second-order factor should not result in a decrease in model Chi-square.
