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.

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.
