Tiredness and fatigue are important in both academic and applied occupational medicine—and the understanding of the link between them and employee health, performance, safety and general workability continues to grow. Loneliness and social isolation of military veterans: The sub-scales of physical and psychological fatigue are not used here, but rather the respondent receives a global binary fatigue score ranging from 0 to 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 been examined in this patient sample.

Cahlder of quality of life with disease characteristics and cahlder outcomes in patients with advanced gastric cancer: The need for a reliable self-completion tool that can measure this subjective condition, either in extreme clinical cases or in routine day-to-day functioning, has never been greater [ 3 ].
Oxford University Press is a department of the University of Oxford. Factor 1 was correlated with subjective everyday cognitive difficulties, concentration difficulties, and a deficit in paired associate learning. Another advantage is that the CFQ 11 is used widely in occupational research and allows for straightforward comparisons cgalder studies and populations.
Exploring the validity of the Chalder Fatigue Scale in chronic fatigue syndrome. 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 tools [ 6 ].
The Likert scoring system allows for means and distributions to be calculated for both the global total as well as the two sub-scales. Data analysis included confirmatory factor analysis to determine the factor structure and model fit, correlations to assess discriminant validity and effects sizes to determine sensitivity to change.

Using the Likert scoring method, responses on the extreme left receive a score of 0, increasing to 1, 2 or 3 as they become more symptomatic. To evaluate the psychometric properties of an item fatigue severity measure, the Chalder Fatigue Questionnaire CFQ in MS including validity of the factor structure, internal reliability, discriminant validity and sensitivity to change.
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.

For all items, the least symptomatic answers are on the left of the response-set, providing an easy-to-understand checklist for respondents.
Factor 4 was correlated with interview and self-rated measures of depression. 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 uqestionnaire within both clinical and non-clinical, epidemiological populations. As a short questionnaire, phrased in simple English with a straightforward answering system, it provides a brief tool to measure both physical and psychological fatigue.
Factor 2 was correlated with difficulties in maintaining sleep. A bi-factor model with one general fatigue factor, incorporating two smaller group factors mental and physical fatigue had good model fit and appeared the most appropriate factor structure underlying the CFQ scale.
Factor 3 was inversely correlated with grip strength, peak Chaldwr, peak heart rate, and peak functional work capacity.
