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.

Chalder fatigue scale – MEpedia

Using the Likert scoring method, responses on the extreme left receive a score of 0, increasing to 1, vatigue or 3 as they become more symptomatic. Cella M, Chalder T. Email alerts New issue alert. Practical Assessment, Research and Evaluation. Afari N, Buchwald D. First, most of these studies adopted the outdated principal component analysis and varimax rotation approaches.

The need for a reliable self-completion tool that can measure this subjective condition, either in extreme ftaigue cases or in routine day-to-day functioning, has never been greater [ 3 ]. From an analytical perspective, the significant and substantial interfactor correlations we found support the use of oblique geomin rotation rather than orthogonal varimax rotation to avoid distortion of the factor structure.

Cutoff criteria for fit indexes in covariance structure analysis: Overall, the respondents displayed moderate levels of fatigue, with item means ranging from. ChanRainbow T. Support Center Support Center. The last author S. Construct validity of the Chinese version of the Chalder Fatigue Scale in a Chinese community sample.


We conclude that ESEM is a helpful tool for model building and development [ 18 ] and recommend that future psychometric studies abandon the use of outdated methods and apply ESEM as a practical alternative to CFA in assessing the psychometric properties of scales. Sca,e Randomized controlled trial of cognitive behavior therapy for multiple sclerosis fatigue. Please review our privacy policy. Chaledr the ESEM models, the two-factor model ecale a mediocre fit to the data.

Exhaustion was assessed using vatigue 5-item subscale of the item Chinese Maslach Burnout Inventory [ 22 ]. The CFS was originally perceived as comprising two subscales that evaluate fatigue in the physical and mental domains. Factor structure of the Chinese version of the Pittsburgh Sleep Quality Index in breast cancer patients.

References Publications referenced by sale paper. Fong Sleep medicine The participants provided informed consent and completed a self-report online questionnaire on fatigue and health measures. Satisfactory reliability and moderate to strong correlations were found chlder the CFS factors, suggesting adequate discriminant validity. The ESEM model has been shown to provide a better model fit and unbiased interfactor correlations [ 1718 ].

The results support the validity of mental and physical fatigue subscales and the dropping of the “loss of interest” item in the item version of the fatigue scale. Exploratory structural equation modeling ESEM is a newly proposed analytic methodology with substantial modeling flexibility [ 1516 ]. Topics Discussed in This Paper. For all items, the least symptomatic answers are on the left of the response-set, providing an easy-to-understand checklist for respondents.


Higher levels of fatigue were linked to greater psychological and physical distress and a poorer quality of life. Fatigue was assessed using the Chinese version of the CFS [ 13 ].

The majority of participants was married Sleep disturbance was measured using the item Chinese Pittsburgh Sleep Quality Index [ 21 ], which assesses seven components on a 4-point scale. The global score also spans two dimensions—physical fatigue measured by items 1—7 and psychological fatigue measured by items 8— Exploratory factor analysis estimates the cross-loadings and results in more realistic factor structure.
