VanNess:

SF-36 vragenlijst-onderdelen

"voorspellen" de toename

van klachten na inspanning

 

 

 

 


 

Een studie van VanNess en kollega's bevestigt wat patiŽnten al weten:

veel klachten nemen (langdurig) toe na inspanning en "herstel" neemt dagen in beslag.

 

Sommige onderdelen van de SF-36 vragenlijst (klik hier en hier voor een vertaling)

hebben wat de ernst en duur van post-exertional malaise een voorspellende waarde

 

Alhoewel het prettig is post-exertional malaise te kunnen "voorspellen" met vragenlijstjen,

heb ik zelf een sterke voorkeur voor objektieve, dus niet te ontkennen, maatstaven

(zoals een afname van de verzuringsdrempel bij een tweede fietstest, bijv. 48 uur later).

Purpose.

 

To determine the validity and reliability of Short Form 36 Version 2 (SF36v2)

in sub-groups of individuals with fatigue.

 

 

Method.

 

Thirty subjects participated in this study,

including n = 16 subjects

who met case definition criteria for chronic fatigue syndrome (CFS) and

n = 14 non-disabled sedentary matched control subjects.

 

SF36v2 and Multidimensional Fatigue Inventory (MFI-20)

were administered before two maximal cardiopulmonary exercise tests (CPETs)

administered 24 h apart and

an open-ended recovery questionnaire

was administered 7 days after CPET challenge.

 

The main outcome measures were

self-reported time to recover to pre-challenge functional and symptom status,

frequency of post-exertional symptoms and SF36v2 sub-scale scores.

 

 

Results.

 

Individuals with CFS demonstrated

significantly lower SF36v2 and MFI-20 sub-scale scores prior to CPET.

 

Between-group differences remained significant post-CPET,

however, there were no significant group by test interaction effects.

 

Subjects with CFS

reported significantly more total symptoms (p<0.001),

as well as reports of

fatigue (p<0.001), neuroendocrine (p<0.001), immune (p<0.01),

pain (p<0.01) and sleep disturbance (p<0.01) symptoms

than control subjects

as a result of CPET.

 

Many symptom counts

demonstrated significant relationships with

SSF36v2 sub-scale scores (p<0.05).

 

SF36v2 and MFI-20 sub-scale scores demonstrated significant correlations (p<0.05).

 

Various SF36v2 sub-scale scores demonstrated significant predictive validity

to identify subjects

who recovered from CPET challenge within 1 day and 7 days (p<0.05).

 

Potential floor effects were observed for both questionnaires for individuals with CFS.

 

 

Conclusion.

 

Various sub-scales of SF36v2 demonstrated

adequate reliability and validity for clinical and research applications.

 

Adequacy of sensitivity to change of SF36v2 as a result of a fatiguing stressor

should be the subject of additional study.
