The paper reports the Flemish contribution to the first phase of an in
ternational collaborative research project operating as the Internatio
nal Consortium for the Study of Developmental Antecedents of the Five-
Factor-Model (ICDA-FFM). Free parental oral descriptions of their own
children's personality are recorded, transcribed, segmented in units a
nd classified with a category system comprising fourteen major categor
ies, further subdivided in facets and clusters. Three quarters of the
parental descriptors for children aged 3, 6, 9 and 12 could be classif
ied as instances of various facets of the Five-Factor Model (FFM). Com
parison of frequencies of classified descriptors across age levels sho
ws a significant increase of descriptors indicating Conscientiousness
and a decrease of references to Extraversion. Analysis at the facet le
vel points towards an age related shift within Extraversion from activ
ity to sociability descriptors. The relationship of categorised free c
hild descriptions to the FFM is illustrated by their consistent patter
n of correlations with factor scores derived from parental ratings of
the same children on 25 scales (Mervielde, 1992) marking the FFM. More
over, most of the free descriptors classified in categories regarded t
o be beyond the scope of the FFM, show significant and plausible corre
lations with the factor scores derived from parental ratings of the sa
me children.
