This research presents a validation of an adaptation in French of the
Boredom Proneness Scale (sp) intitled ''Echelle de disposition a l'enn
ui'' (EDE). Three studies were conducted to evaluate psychometric prop
erties, construct validity and structural validity. A first study with
student participants demonstrated acceptable fidelity (test-retest re
liability, internal consistency...) and validity indices. However a co
nfirmatory factor analysis did not support the unidimensional structur
e of the Boredom Proneness Scale. The second study with a sample of dr
ug addicts assessed the validity of the scale using the ''Known-Groups
'' method. Results supported the construct validity of the scale. A th
ird study examined elderly persons. Results of this study point to the
reliability and validity of the french version of the Boredom Pronene
ss Scale. Furthermore, a bidimensionality of the boredom construct was
found through an exploratory factor analysis.
