Most investigators have reported only between group comparisons
of mean scores and not proportions scoring in the clinical
range. However, Gibson et al. (2000a,b) report that 5% and
Glazebrook et al. (2001) 17.1% of ART mothers of singletons
had clinically significant depressive symptoms. This might be
attributable to sampling differences; Gibson et al. (2000a,b)
recruited socio-economically advantaged Australian women and
Glazebrook et al. (2001) a more socio-economically diverse
English sample. However, it is more likely to be to do with the
EPDS cut off score that was used and the timing of assessment.
