Van Hoof, E., Coomans, D., Cluydts, R., De Meirleir, K. The Fennell Phase Inventory in a Belgian Sample. Journal of Chronic Fatigue Syndrome. 2004;12(1):53-69

Purpose of the study:

  • Replication of prior empirical evidence purporting the structural robustness of the Fennell Phase Model
  • Additional analyses regarding the stability and utility of the Fennell Phase Inventory (FPI)
  • Examination of the utility of FPI in the development of treatment plans

The study was a prospective randomized study, with subjects selected from an outpatient Chronic Fatigue Syndrome clinic in Brussels. The pool from which subjects were selected were individuals presenting at the clinic for medical examinations to exclude other explanations for their excessive fatigue.

Results:

  • The study supports the distinction between the phases and appears to capture the Fennell Model.
  • The Fennell Phase Inventory was found to be valid and reliable in the Belgian sample.
  • Health promotion strategies, which influence both the individual and populations, can then be utilized within the Fennell Phases to facilitate more appropriate treatment outcomes.
  • The Belgian sample shows improvement in the dimensional assessment, as well as in the immune parameters, suggesting physical improvement over the different phases.
