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 Afari N, Buchwald D. First, most of these studies adopted the outdated principal component analysis and varimax rotation approaches.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.

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tool for model building and development [ 18 ] and recommend that future psychometric studies abandon the use of outdated methods and apply ESEM as a practical alternative to CFA in assessing the psychometric properties of scales.

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.
